Edmonton Rooftop Balcony Leak Repair, July 2015

Rooftop Balcony Leak Repair Edmonton - Below you will find a series of ongoing reports for a residential client in Edmonton, Alberta. The client requires leak maintenance where a PVC rooftop deck and a tar and gravel flat roof connect and flat roof recovery or replacement to the tar and gravel flat roof. Project manager notes have also been included.  This single family home in Edmonton Alberta has a second story rooftop deck (a deck that is over a heated living space is considered a rooftop deck - it needs a membrane suitable for over heated living spaces such as a flat roof membrane). It issue is the homeowners recently purchased the home and came to realize the second story balcony was leaking in to the home causing significant damage. So they hired a deck company to replace the membrane on the deck, but the decking company could not re-connect the balcony membrane to the tar and gravel roof that runs around the house as a skirt. The home-owner asked us to inspect the tar and gravel flat roof skirt and the need for the rooftop deck membrane to be connected properly (the deck membrane that was recently installed is a PVC and the PVC will not of course bond to a tar and gravel roof so a break needs to be constructed and then both the PVC deck membrane and the tar and gravel roof need to be tied in correctly). They also asked us to inspect the tar and gravel flat roof on top of the house. Update (07-30-2015): More posts to come as the work continues at this site. Update (07-30-2015): Quotation added New Client Call, July 24 2015:
  • Service: Roofing
  • Type: Residential flat roof
  • We have small issue with the roof section that joins up with the deck. There is water infiltration culminating in leaks.
Background The client purchased their home a few years ago; it is two storeys. The second story has a walk-out balcony over a heated living space. The balcony itself connected to a tar and gravel roof skirt that goes around the house. The balcony membrane was in a failed condition, so they had it replaced with a "vinyl" deck membrane not long ago. An inspection will also be required for the tar and gravel flat roof on the main roof. Concerns:
  1. The flat roof skirt that wraps the house which connects to the vinyl deck needs an assessment for replacement options.
  2. Most recently, there was a water ingress as the previous decking contractor did not correctly set a temporary waterproof scenario where the deck meets the flat roof skirt. An infrared technologist was called in and said there is no considerable issues in the walls, but considering the flat roof skirt's age there may be an issue with rotting joists or sheathing.
  3. An inspection is required on the connection area between the vinyl deck and the flat roof skirt. Is there a suitable break between the two sections appropriate for us to roof in the skirt properly?
  4. Inspect the main flat roof above for any maintenance concerns and estimate the expected life-cycle for future replacement considerations.
  5. Ask the client for the manufacturer name of the vinyl used for the most recent roof/deck replacement. When a roof deck is installed over a heated living space, there needs to be a product that is intended not only for use as a deck membrane, but also as a rooftop (low slope) roof membrane.
Assessment, July 25 2015: We arrived on-site at 1:00 pm and the client asked how much it would cost for us to only tie-in the new DuraDek material to the little roof that goes around the house as well as both ends where the deck and roof meets. The roof itself is a BUR roof and it was leaking into the house on the left side. The other end is fine, but the client wants some tie-in maintenance done there as well. We also did a main roof inspection for completeness.

Roof Deck Drainage and Waterproofing

ARTICLE:  Roof Deck Drainage Problems. Waterproofing a 2 Ply SBS Modified Bitumen Roof Balcony in Edmonton, Alberta.

Recommendations for Waterproofing Outdoor Decks Over Conditioned Living Space. Roof Deck Drainage and Waterproofing - Inspection and Repair of a Torch-On Flat Roof on Outdoor Balcony at Multi-Family Condominium. Customers regularly call on us to have roof assessments (inspections) completed. During a roof assessment our journeyman roofers assess the roofs condition. We assess the roof for preventative maintenance reasons as well as inspecting existing problems that the customer is pointing out. We then discuss different scopes of work fix the problems as well as potential materials and costs related to the repairs. One of the most common calls we get for inspections and repairs are rooftop decks, balconies and patios. The primary reason the failure rate on rooftop decks is so high is because of the original installation. It is common for incorrect membrane choice to be the reason. In other words, many people install an outdoor deck membrane that is intended only for an outdoor deck and not a membrane for over a heated living space. If your rooftop deck or balcony is over a heated living area you require a special membrane that is also intended for low slope roofing (as well as deck waterproofing) and is approved for use over a conditioned living space. Common products for this are Dura-Deck or DecTec, both of which are a PVC membrane that are suitable to be walked on (so they do not require a floating deck over top) and they manufacture membranes suitable for over a conditioned living space. We use DecTec extensively and have had great results with it. Or, also common is the installation of a membrane that won't hold up to the foot traffic associated with outdoor living areas. Other reasons include simple age, wear and tear, drainage and issues relating to penetrations or floating deck assemblies on top of the membrane. Visit our main website for more information on rooftop deck waterproofing. This particular inspection and subsequent repairs was more focused toward an aging membrane and the associated repairs that come with not properly maintaining the deck membrane and building envelope over the years. The drainage problems were causing significant damage to the exterior of the building. Below you will find the inspection report. May 20, 2015: Journeyman Superintendent Attends for Balcony Inspection. Roof Inspection Location: 10245 116 Street NW Edmonton Alberta. Roof Inspection Date: May 20, 2015.

Athabasca DecTec Balcony Assessment, February 2015

Our client, located north of Edmonton, reached out to GRS to explore the option of installing DecTec Membrane on a balcony off the second floor of their building. Scope of Work: 1) Removal and disposal of existing roof assembly under the existing membrane that would interfere with new surface installation. 2) Removal/replace rotten sheathing (if any). 3) Mild increase to slope to encourage drainage. 4) Door openings may have to be customized to account for new slope. 5) Flashing may have to be re-done to accommodate new slope as well. 6) Deck railing removed and replaced to ensure safety. 7) Waterproofing of walls to allow for vertical installations. Ensures watertight fit. 8) Upon completion of 1-7 (as necessary), floating deck can then be installed to support viable systems (SBS Modified Torch, EPDM, TPO, or PVC), though DecTec does not require a floating deck to sit atop the membrane.   Proposed Solution DecTec bore GRS's recommendation for this project, as we employ all of the technicians typically required to see a successful installation. The client was simply looking for a quote for this type of project, which we were happy to provide.   Existing Decking: Pre-DecTec Installation 1 Pre-DecTec Installation 2 Pre-DecTec Installation 3 Pre-DecTec Installation 4 Pre-DecTec Installation 5 Pre-DecTec Installation 6     Until next time,         The Roofers at GRS CODE: 4510 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Rooftop DecTec Installation, March 2014, Edmonton

This client's residence bears a flat roof with a leak in one corner of the tar and gravel system. Upon GRS' inspection, however, the client desired to explore options for a total roof replacement and its conversion into a rooftop deck. Continue reading Rooftop DecTec Installation, March 2014, Edmonton

Edmonton Commercial Roof Deck Installation, March 2014

This commercial client in Edmonton required a Dec-Tec roofing installation by the GRS crew. Several decks are being installed on this site. This report follows the deck installations, however additional roofing work was completed on this site at a later time. Additional reports will be made for the subsequent work. Note: This report is text based and does not contain progress photos.
Roof Report, March 23, 2014: This morning we removed the old deck down to the substrate and found some rotten plywood in the corners which we will have to replace with 1/2 plywood. The entire perimeter will also need to be replaced with 3/8 plywood as it was coated with asphalt which is not compatible with this system. I need to alter the ordered slope package to include a drain. I cut some wires while prepping the wall, so I am going to need some heavy rubber gloves, wire strippers and some heat shrink wrap. We removed the roof until 4 pm and download garbage until 7 pm. Materials Required:
  • 11 pieces of 8 ft. drip edge.
  • 5 pieces of  3/8 plywood.
  • 3 pieces of 1/2 plywood.
  • 10 short sawsall wood blades.
  • 1 roll of garbage bags.
  • 3 drains.
  • 3 scuppers.
  • An industrial heater (for dec patch and gluing).
  • Heavy rubber gloves.
  • Wire strippers.
  • Heat shrink wrap.
Roof Report, March 24, 2014: I got the crew going in the morning and then went to the landfill. Once I returned I started on repairing the wires that I cut the day before. I realized that there was a lot more damage to the wires and I had to go back to home depot for more supplies. Once I fixed the wires and the crew fixed the substrate we then had a hard time fitting in the drip edge behind the building membrane. An important note about the decks is that they will have to be insulated from underneath. Vapour barrier needs to placed on top of the ceiling drywall to ensure an energy efficient building. This should not be that much extra for them since the ceiling drywall is damaged in those areas. I am thinking I could use another crew member to assist with this site. We may also require an electrician to assist with the wiring.
Roof Report, March 26, 2014:
Once I got to site this morning I knew I had to fix the back slope of the substrate on the west side.  The electricians showed up at 10:15 am and fixed the wiring on the roof.  The power is working and their repair is to code. We finished the slope repair and then went to drop off the sliding door screen for repair, and pick up the slope package from Plastifab.  Unfortunately the package we picked up turned out to be the wrong size. I am going to get the guys to remove and download the floating deck until I come back with the right slope package.
Roof Report, March 28, 2014:
We completed the slope package and the install of 5/8 plywood. During the process I saw the need for light gauge 90 degree metal to minimize gaps around the perimeter. Short of the scupper which we should have by noon tomorrow, we are ready for the dec patch and heaters. Tomorrow we will start with relocating the scupper from the outside and if time and weather permits, tarp and start on the removal of the the next deck in the NW corner until the proper size scuppers arrive. We would have started on these items but high wind in the afternoon made our next set up too hazardous.

Roof Report, March 29, 2014:
We started the day with the repair of some installed screws and then sanded the laps in the 5/8 plywood dec-tec substrate. We also installed caulking and dec-tec kick under the patio door and window. At 12 pm we then started to tarp off the area around the next deck and began removal. This area has been damaged by water for some time and is full of mold.  We may have some framing issues as the original substrate has been water damaged as well. I strongly suggest that the drywall on the ceilings and walls under this deck be completely removed to check for water damage and mold. The proper installation of insulation and vapor barrier under the deck above the ceiling drywall is necessary as well. There is also the issue of the siding as it has been cut as high as 4 ft in some places. We need to consult the client about what they want done for this. It will look a little strange if I bring my membrane that high. We should find out if they want the same type of siding installed (which would require all of the siding to be redone), or if they would prefer a different type of siding.
Roof Report, April 15, 2014:
This morning we had to work on fixing an area that wrinkled while we were installing the dec-tec. Bringing up the membrane even 12 inches is making the install difficult. There is 15.5 inches of unfinished wall that will have to be completed when the other siding is installed.
Roof Report, April 16, 2014:
We continued with installing the second dec-tec today, short of a couple of pieces to finish. I had to put a patch over the scupper because of dripped glue. Tomorrow I will be finishing the seal on the second deck and down loading the tools from there. We should be done the second dec-tec installation by 10 or 11 am tomorrow morning, short of one lap that I need the 90 degree tool for. Then it will be ready for the Tyvek building paper and the scupper box install. All of the deck areas above the metal cap flashing need to be patched of holes that we put in to build the temporary roofs. This should take us a half a day and the repair of the back wall should take 2 days. I still need to take the trailer to the dump one last time, but I am waiting till the end of the job to do that. We have some matching downspout pipe and 90's for the drainage so there will be no extra cost to us moving the scupper from the original location. I have already bought the matching paint for the scupper boxes.
Roof Report, April 17, 2014:
Today we finished off the dec-tec and installed building wrap to the substrate walls to ensure no water gets into the system. Most of the upper area that is not covered by the membrane is 10 inches and the open area by the scupper is 15.5 inches.
The lowest part of the membrane is 12 inches off the field which is at the peak of the slope package. We worked on the membrane until 12:30 pm and then started to secure the roof and download the most important tools. I will drop off the mountain of receipts and paperwork some time this weekend. Depending on the weather when I go back to Edmonton, I may need to pick up some heaters again.

Edmonton Rooftop DecTec Installation, December 2013

The report below follows repairs made to this client's residential roof deck. They sought a DecTec installation, replacing the existing system with one to be more reliable. Unfortunately, the in-progress roof reports' photos are no longer available; the placeholder image above is another project of GRS' that illustrates a similar roofing system.   Inquiry Received: September 9, 2013 When we first heard from the client, they told us that their deck is built right into the roof (as a cutout), and the flat floor seems to have leaked. It appears that their previous repair job was not done properly, and they had worries that there would be more existing issues that had not yet been discovered.   Quotation Delivered: September 11, 2013 After hearing about the situation, GRS project management delivered a quotation was for roof deck repair and/or replacement options. We booked them in for service, set to repair the problematic areas.     Roof Report: December 7, 2013 Given the temperatures and snow buildup, the technician began their time on site by bringing up the heater to warm up the deck. By raising the temperature of the decking surface, it would be better prepared to accept the patching material. While the deck surface was warming up, the technician planed and sanded the deck joints to give a flush connection. At that point, the servicing technician installed the deck patch to alleviate problems with the reported leaking. They went over the next steps with the client, letting them know that the existing slope of the deck is moving water into the drain nicely. The rest of the job should be completed the following Monday with the DecTec installation. The GRS technician waited for the deck patch to set and dry in place. They put together a plan for the scope of work yet to be completed; details below.
  • Sand the deck patch down.
  • Cut the plywood on the walls to a height of 6", as the old membrane will not come off the walls and there is a gap from where the deck was lowered.
  • Replace the removed plywood with 1/2" plywood boards.
  • DecTec to then be installed.
  • Must then install peel-and-stick membrane to the door frames, power outlets, and lights in the area.
  • The vapour barrier must also be installed where needed.
  • The handrail, which is currently in a rotten/poorly state, will need to be removed and replaced with a new piece of lumber (2" x 8" x 12')
  • Install more peel-and-stick membrane to the top of parapet walls and the new hand rail.
  • In Spring 2014, Hardie Board and metal trims can be installed. It may be able to be done sooner, as the product doesn't need to be painted.
Unfortunately, the photos for this site are unavailable - please accept our apologies!   Roof Report: December 10, 2013 The GRS crew arrived on site for 8:00 with the day's paperwork only taking them until 8:15am. They began tearing out the plywood walls, working through 11:00am. After that, the area was cleaned and prepared for the floor membrane over the next couple of hours. The DecTec was installed between 1:30 and 6:45, with one of the team members departing for the evening around 4:00pm. The site was cleaned up between 6:30 and 6:45pm, with garbage disposed of and the materials and tools packed away.     Roof Report: December 11, 2013 The team started their day for 8:00 once again, filling out the pertinent paperwork and bringing all tools and materials into the work area by 8:30am. They began preparing the walls for the Tyvek wrapping by removing all of the preexisting staples and nails from the structure and surface. Half an hour later, they began installing the Tyvek wrapping, taped up the joints, and affixed peel-and-stick membrane to the area. The membrane was all installed by 5:00pm, so the team spent the next hour and a bit cleaning up the site, removing the materials and tools from the work area. Come 6:30pm, they were prepared to depart for the evening, and the jobsite complete.   CODE: 649 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Deck Membrane Replacement, April 2013, Edmonton

This residential client reached out to GRS to replace the membrane of their home's decking system. GRS ensured that everything was done to specification, in addition to some light repairs on the client's garage roof.   Quotation Delivered: February 26, 2013 GRS delivered a quotation for the membrane replacement on their existing deck that sits above a living area. The existing membrane would need to be removed and replaced with a new SBS system and some drains to accommodate the water ponding.   Client Correspondence: March 28, 2013 We sent word out to the client that the senior journeyman roofer would be attending the site this day around 5:00pm to go over the installation specifics. The journeyman was briefed ahead of time to understand that the scope of the work covered removing the existing membrane to the decking, then apply a 2-ply charcoal SBS Modified roofing system. If further work needs to be done to adjust slope or substrate repair; the journeyman will be able to assess the situation at that time.   Roof Report: April 8, 2013 A previous report (consisting of the membrane removal) is, unfortunately, no longer available. Work description: The crew arrived on site to continue with the deck surface replacement, so they started by removing the wood siding's first (bottom) row, and tarred the existing two layers of decking. The rest of the deck was the cleaned up and the gravel stop prepared for the new membrane. With that complete, they installed a layer of IKO Armourbond Flashing on the deck, including all corners and up the wall to 8" height.   image006image001 image002 image003 image004 image005         Roof Report: April 9, 2013 The garbage was all cleaned up, picked up, and disposed of before the crew got to the torch-on capping. As with all open-flame procedures, there was a fire watch protocol to carry out, so the team waited on-site for the prescribed time, working on sheet metal over the nearby garage in the meanwhile. Spots and laps were caulked to shore up the watertightness of the area.   Roof Report: April 11, 2013 The crew began by removing four old drains and replacing them with new ones. Shortly after, they moved to cut away the base sheet from the gravel stop and stripped it in correctly. Then, the cap sheet was cut and prepared for the following day. The crew had to seal up all of the exposed seams to waterproof it properly, before the cap sheeting could be applied.   20130411_114641 20130411_114656 20130411_163306 20130411_171017     Roof Report: April 12, 2013   This day, the crew used seven full rolls of SBS (black) cap sheeting and half of a roll of base sheet on the decking area. The four new drains were installed and the siding that had been removed some days earlier was replaced and installed into its original place.   Roof Report: April 13, 2013 All of the cap sheet was torched and installed to specification, and the site cleaned up of garbage. With the garbage disposed of, the project was now considered complete. 20130412_154320 20130412_154353     Warranty Repair Request: July 28, 2014   The client reached out to GRS to request an inspection on an area of the decking that was damaged during a patio door installation. Now, the deck appears to be leaking into the room below, and they would like it repaired. GRS booked a technician to go on-site the following day to see what needed to be dealt with.   Inspection: July 29, 2014 The technician went out to the client's location and began inspecting the decking area. There were some damaged spots, but (fortunately) none of them appeared to be a through-and-through puncture into the membrane. Upon visual inspection, the leak could be traced to a certain degree of accuracy, but the area underneath the new door is inaccessible without removing the doorframe around it. GRS delivered a new quotation for the repairs, and this report will be updated if/when work continues on this site.   Photos: Service Follow-up, October 21, 2015 Some additional photos were submitted to show how the canopy was holding up.

Edmonton Roof Deck Replacement and Waterproofing, October 2011

This residential client was provided with a quotation for the replacement and re-installation of a proper decking and waterproofing system. There is water leaking into the home and proper draining systems need to be installed. This report also includes a follow-up service call. Inspection, October 8, 2011:
The client is looking to have both decks re-surfaced and proper drain systems installed. There is moisture getting into the home in the daughters room. There is also dimpling visible on the ceiling and screws were dropping down, those have since been plastered over. Both decks are pooling water and are improperly sealed. The client believes there is stucco below the deck and has questions about damage to it or the foundation during the process. The client is also looking to have new eaves-troughs installed.

Roof Report, November 27, 2011:
I am unable to give as much slope to the decks as the customer would like as the threshold under his doors is only 1" after I rip the old roof off. I plan on using sloped fiberboard around the wall lines as this will only build it up by .5" and give some sort of slope at the walls. As the threshold is only 1" under the door I don't want to use FR board because this will build the roof up too much. Instead, I plan on using the fast and stick 180 base-sheet as this is mechanically fastened and can be used directly on the plywood deck. Along the wall lines the stucco starts 1" above roof line. In order to be able to ensure a good seal I want to put plywood strips along the wall line at the height of 4" to give me plenty to seal to on the walls. To make this look better for the client I would like to use a black metal flashing over my wall line cap-flashing (to make it look more like crown molding, and it will match the metal cap at the top of the wall). The door provides me with a bigger problem. I would like to run my cap flashing up onto the door sil as this will give me more to seal to instead of trying to work under it as it is only 1". As I know using the torch on his door sil presents a real fire hazard, I would like to use a peel and stick 250 cap with the IKO S.A.M adhesive and a detail roller.

Roof Report, November 30, 2011:
We ripped off the larger of the two roofs at the back side of the house. Once the old membrane was ripped off we inspected the plywood deck, the plywood was wet but not rotted out in any spots. After the plywood was inspected we put our plywood strips around the perimeter of the building to allow me the height I need to seal my ply's. Once the plywood was installed we cut fiber board on a 45 degree angle and screwed it along the perimeter to create as much slope as the threshold under the door would allow. Once the fiber board was screwed down we laid out our rolls of fast and stick 180. Then we screwed it down for our first ply of the system and torched the laps to make it all water tight. This morning we lost a couple of hours removing snow and chipping ice. After we got all the snow and ice removed from the roof we primed half of the perimeter. I put on the armourbond flash up the walls and sealed it to the top of the plywood to ensure a strong seal. After I finished the flashing I was able to put down half of the 250 cap sheet on the flats of the roof. Once that was done i degranulated the perimeter and moved all of the customers belongings on the deck to the completed side so I can get a good jump start in the morning.

Roof Report, December 4, 2011:
I went to work on the front deck of the house, we ripped off the old membrane and inspected the plywood deck for rotten areas but none were found. As with the back deck the plywood was found to be wet but not damaged in any areas. After we dried the plywood as best as possible, we built the plywood walls around the perimeter to allow me to seal my ply's. Once the wall lines were installed, we used strips of fiber board cut at a 45 degree angle to create as much slope as the threshold around the door would allow. Then we screwed it down. After the fiber board was laid out I was able to lay all of the 180 fast and stick base sheet over all the flats, screwed it all down, and torched all of the laps. Next the plywood wall lines were all primed so I could put my 180 capping on the walls. I was able to cap half of the wall with 180 peel and stick capping, starting from the drain and working out. To make things easier for our next day I torched down my first run of the 250 cap sheet on the flats.

Roof Report, December 12, 2011: This morning we returned to the client's house to continue work on his roof decks. After we finished drying the roof I completed all of the peel and stick capping around the perimeter including under the doorway. Once the 180 capping was complete I finished the flats with the 250 cap sheet, and finished degranulating the perimeter of the 250 cap sheet. I was also able to complete about 40% of the 250 capping along the wall lines. All I have left on this roof is to finish the 250 capping around the wall and put all of the customers furniture back where it was when we showed up. I plan on drying the smaller roof in the morning and then ripping it off first thing.

Follow-up Service Call, March 14, 2012:
Arrived at the site and the client showed us the water damage in both of her children's rooms, however there was no water damage in the bathroom between the two rooms.  After inspection of the SBS roof, there were a few blisters starting. These blisters were not attached to any exterior wall or opening in seams, so we suspected that it was moisture underneath the membrane and not a leak from roofing system causing the blister. We discussed with the client that because of the ice on the roof it would be best not to continue the blister repair at this point. Client mentioned that her husband was shoveling the snow off the deck as a preventative measure, which may or may not indicate any attempt to clear the drain. We did suggest that we could conduct a flood test to give the client peace of mind. This would test whether any rain in the meantime would leak from our drain installation. The customer agreed and gave permission for the flood test and remained just inside the home with an open door between us and her. We conducted the flood test and initially there was no moisture coming through where previous leaks occurred.  However, after 30 minutes of flooding the roof on deck, the clients nanny told us that there was a water leak in the kitchen, the floor beneath the original leak locations. At this time we turned off the water. As we came downstairs to inspect the new leak, we suspected that the leaks were not caused from a leak in the membrane on the deck, nor was the problem just a leak around the drain area.  The leak in the kitchen was substantial and furthermore there was water running down over the back entrance on the exterior wall.  After noticing this we went back to the original leak areas (ie. the children's bedrooms) above the kitchen, at which time we noticed that the floor was getting wet in the bedroom directly above the kitchen. We noticed the sound of dripping water while standing in the bathroom between the two bedrooms, client was present when mentioning the sounds coming from inside the walls. It is our conclusion that for this amount of water to penetrate such a large area of the house in such a short time frame the water must be coming from the drain pipe. It is attached to the drain bowl which is enclosed in the wall and exits the exterior wall between the first and second floor (ie. between the kitchen and bedroom directly above). At this point we told the customer that this was not a roofing problem, and that she had a drain problem which would require a plumber. We further advised her that this is not warranty work, any problems to roof assembly that have occurred because of the drain problem would be addressed after the plumbing problem is fixed and would then be chargeable work as our warranty is void if there is an already existing issue outside of the scope of our work.  She is also aware to e-mail GRS with the progress and completion of such work.

Roof Report, March 15, 2012:
Arrived at clients home and inspected both drains. First drain inspected while the client poured water down the drain. Fairly steady drip came from seal from the inside of the bowl. The second drain was inspected from open ceiling and the leak was not the bowl itself but the insert attached to the bowl had a horizontal split which was the cause of a substantial leak. We are not certain as to who installed what in this plumbing section. Inserts do need to be changed out. To temporarily fix the leaking we caulked the split on one drain and caulked the ridge of the compression ring on both drains.  We explained to the clients that it is a temporary fix until further action is taken on the part of GRS or a plumber. The split could be a manufacturer default or a crack which was then split from freezing water, or it could be due to someone trying to clear the drain with an object. These are just possible reasons for an uncertain situation and speculation based on the fact that the crack was horizontal. We explained that once the deck is dry and a course of action is decided upon, the drains will be repaired and the blisters would be fixed at the same time.

Service Follow-up, April 1, 2012: The following email was sent by the client to our project manager:
I have water flowing into my great-room, over the deck (currently out of 2 spots at a great rate of flow). There are wet spots all along the path likely leading to the drain area in the front.  The back deck remains ok, with no drainage, but covered up with the tarp still.  The areas fixed on Thursday look intact, but the edges of the repairs are mixed with water and the "fix it material". I have photos and video.  This is similar to what happened in Dec after the original remediation on the decks which supposedly stopped the issue. He told me at the time it was likely an interface with the drain issue that he was able to stop with some caulking. Any thoughts or suggestions on stopping this flow and ongoing issue?
Following this email a crew member was sent out to inspect the leaks, the inspection notes are below:
Client indicated the leak is a very small amount of water that only leaks during a heavy rain fall. The amount is about two to three table spoons of water. The leak comes off of a truss. The client has caulked the metal around the balcony on the bottom which has solved prior leaks.
We flood tested on top of the metal where it was caulked and we attempted to flush water up behind the metal.  The truss started to get moist.  We re-caulked the fastener heads and the old caulking. There may have been pin holes in the caulking. If this doesn't stop the leak then the metal flashing may have to be removed to diagnose the leak further. The roof is wet due to rain and there is rain in the forecast for this afternoon. The client is happy with the trouble shooting and is willing to wait and see if the leak has stopped. There are three buckles that will need to be addressed in the near future.  This can be done with ms detail and grey granules, weather permitting.

Edmonton Residential Roof Deck Waterproofing Inspection, July 2011

This client required a quotation for various waterproofing options to fix a leaking deck. Our crew was dispatched to provide an inspection and to determine where the leak was coming from. Inspection, July 27, 2011: I arrived on-site and the client took me to the garage and showed me where water was still dripping down from yesterday’s rain. They have the drywall and insulation stripped in the area where the drain comes down from the flat roof. I set my ladder up on the cross beam that runs across the garage. I was facing the entrance to the house. The floor joist runs just to the right of the roof drain, it is spliced on the cross beam that I had my ladder leaned up against and it appeared to be soaked between the two joists on the splice. The splice and also a very short piece of 2x4 about 2” long appears to be screwed to the deck from above. When I stuck my finger between the 2x4 and the joist it was saturated, this is the area where the water is coming in. It is within a foot from the drain area but the drain or drain pipe itself was not wet at all after running a water hose down it to test it. The client did say that the water does not come through right away when it begins to rain so the leak may not be in the immediate area but I am convinced it is coming from the flat roof. I inspected the shake roof surrounding the flat roof but didn’t find anything that I felt would be the problem.

The inspection of the drywall and insulation revealed that the entire assembly was saturated with water from leaks.
100_1210
The technician's ladder was setup on the crossbeams across the garage. From this view, our technician was able to inspect the floor joist that ran just to the right of the roof drain.

After inspecting the flat section of the client's roof, the technician could not easily surmise what was causing water ingress.

Photo Gallery: Edmonton Rooftop Deck, September 2010

This report serves to show the before-and-after difference that a rooftop patio reconstruction can make. There are no in-progress reports to cover; just a photo gallery to highlight the expertise that GRS can bring to your household upgrades.  
001
After removing the original roof membrane and step flashing from the perimeter of the patio, we applied new roof boards to the surface.
002
This custom fit section is where we would later install a drain. We ensured that the piping was in full repair and that the surrounding roof surface had no deficiencies.
004
Once the boards were installed, we began laying EPDM over the roof.
 
005
EPDM was secured against the wall connections using termination bars around the perimeter. This contributed to the watertightness we were aiming for.
006
Completed drain installation.
008
010
Post-installation photograph, with terminal bars completely installed around the perimeter. All that remained was liquid rubber coatings over the seams.
009
Detailing at the door. The EPDM is folded over itself underneath the termination bar.
