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 Residential EPDM Roof Recovery, October 2013

This client in Edmonton required a quotation for an EPDM roof recovery. The report outlines the recovery process carried out by one of the GRS crews. Roof Report, October 25, 2013: We arrived on site at 9:30 am to measure the roof and order the material for the job. The bin arrived at 12:00 pm. We started to remove the gravel and were about half way done by 6:00 pm. Roof Report, October 28, 2013: The front entrance is finished but the back one is only just started and I will have to continue in the morning. There are some issues with the metal beyond my capabilities but as far as the roof is concerned it will look great when complete.
Roof Report, October 30, 2013:
Today we completed the small EPDM roof at the back of the building and then left to work on another site. We then returned to remove water from the roof area that we are starting on tomorrow.
Roof Report, October 31, 2013: We managed to lay out the first 20 ft. run across the main roof and through most of the details on the roof. The EPDM was not fully relaxed and I have some wrinkles to deal with tomorrow. We will push through and have it sealed by Friday afternoon.
I will require another crew member to assist with the metal wall detail on the smaller roof. There is only a 2 inch lip on the outside perimeter of the main roof, but the existing metal seems to still fit well. I had the crew dry out and prep the next area to be completed and I worked on getting the details done from the previous day. Then we were shut down by high winds.

Roof Report, November 4, 2013: With the crew being down to 3 of us for the day and me leaving for the weekend, I needed to make sure that the roof was 100%. We completed the rest of the details and cleaned up the metal for re-use. Then we installed a tie in and prepped the roof for snow.
Roof Report, November 8, 2013: I am going above and beyond on the details to ensure that the roof will last and not leak. We have 12 ft. x 47 ft. of roof left to install as well as the metal. I am going to need both trucks to get all my supplies and tools back to Calgary.
We managed to finish the field and have a few details left to complete the roof. We had just enough rubber to finish with a few scrap pieces left over. The roof should be completed by Sunday afternoon, short of some metal on the inside walls of the lower roofs. I need another crew member to install those properly as it could cause problems later if not done right. Roof Report, November 8, 2013:  
After dealing with both trucks in the morning we didn't get to start roofing until 10 am. It was slow going due to the weather, but we managed to get 30 ft. of perimeter detail, 1 plumbing vent, 2 curbs, and another 4 ft, of outside detail done on the other side. We still have another 15 ft. of perimeter detail to seal and an over flow scupper to seal in. Then the upper roof will be completed with regards to the EPDM install.
Roof Report, November 10, 2013: We completed the EPDM part of the roof, and I got all my tools and supplies back to Calgary. There were a lot of wrinkles on the roof after we were done but I made sure none of them went through laps.
All of the original metal is secured on the main roof. There were some hinges on the roof hatch that if reinstalled would have made the roof leak, so I left them alone. I left a message with bins by Joe and they will contact me when the bin is removed. After that I will let the crew know that the plywood and clean up can begin. < End Report >

Edmonton Industrial Flat Roof Replacement, September 2012

This industrial client required a full flat roof replacement with additional work attached to the project. This included painting of vents and painting of the frames that run the perimeter of the building.  Roof Report, September 18, 2012: The crew arrived and began removing the gravel from the rooftop as well as loading the materials into the site area. photo (12) photo (13) photo (14) photo (15) photo (16) photo (17) photo (18) photo (19) Roof Report, September 19, 2012: The crew returned the next day and tore off an area 16 square ft. wide.

  The client reached out to us regarding the time line of the roof membrane installation. The following emails are between our project manager (italicized) and the client: Are we planning to attempt something tomorrow?  Need to give status of repair job plans by 8AM as they will be bugging me again.  Just to recap they will be asking for more detail on repair job as time stretches on and more detail on backup plans if weather stays cool and wet until snow falls.
Hi, To complete the roof membrane portion we require the roof to be dry on top for at least 24 hours. As such, the weather will determine what day that occurs. Based on the forecast our scheduling is for this Wednesday or Thursday. If for some reason we cannot accomplish this task before freeze up then we will hoard. However, in all our experience with this product we have never had to, we have always, every year completed all scheduled sites before freeze up. The material can be applied to - 10 celcius which gives us ample time. After we have completed the last coat we then have to do metal which can be done in any temperature. When we consulted the manufacturer about the recent moisture after spraying it was made evident that there were a few isolated areas that did not have time to cure and of course moisture penetrated. Also we were advised that any existing moisture in the system would manifest in the form of a blister. If no blisters are present after completion we are good to go. If present, we cut that section out and replace. Thanks.

Edmonton Commercial Roof Leak Inspection, June 2012

This client in Edmonton required a roof inspection due to leaking that was occurring during heavy rainfalls. This brief report outlines the initial inspection and includes photos of the site. Inspection, June 13, 2012: Upon arrival at the site we talked with a manager who directed us to the roof hatch and the damaged office area. We spoke to the person whose desk was directly under the leak, and he noted that the leak only occurred when there was very heavy rain. All vents in the problem area described were inspected. The plastic cement was also inspected and it appeared to be solid. We determined that the large unit in the area was the source of the leak (we calculated it to be directly above the leak area). We scraped the gravel from around the unit and lifted up the flashing in order to get a better look, and to expose the area for the incoming rain. After the rain had passed, we inspected both the unit and the office area. No leaks were found in the office area. We swept the pools of water around the unit onto the unit itself, trying to provoke a leak, but there were still no leaks. This led us to conclude that there were no leaks in the roof, and the leak that occurred previously was due to the rain being so heavy that it must have overflowed into the unit itself; if there was a problem with the roof, then the rain today would have exposed it.

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 Flat BUR Roof Repair and Maintenance, September 2010

This Edmonton client required repairs to an existing built up roof system. Some areas on the roof appear to be blistering and others have ponding water. A crew was dispatched to perform the repairs once the weather was suitable. Note: This report contains several separate repairs and maintenance reports completed at different times.
Scope of Work: Repairs to Existing BUR – Built Up Roof System.
  • 7 areas of the roof have blistering that requires repair.
  • 3 areas of the roof have ponding that requires repair.
  • 2 units show water penetration to the interior.
001
Some blistering in the roof around ventilation vents, with signs of moisture buildup.
002
Exposed blistering sticking through the gravel layer.
003
Holes in the base of a plumbing vent. During periods of precipitation, water has a direct point of entry into the building through holes such as these.
004
Significant signs of moisture buildup lead from evaporated standing water.
005
We removed the gravel around sections of significant moisture buildup to expose the roof surface. We found small pockets of waterpooling, which was also entering the building through the various blisters and tears that were identified.
008
Spudding over some tears.
007
Parts of the underlay that bordered with the edge of the shingle roof section were curling up, and required refastening. Moisture was entering the building through here.
010
Cement was applied over the sections of the roof where we had found significant standing water.
013
For smaller holes and blistering, we applied spudding, mesh over top, and then followed up with a second layer of spud.
  Roof Report, January 28, 2011: Investigated roof leak, approximately 18" frozen snow on roof. Checked all repairs done previously and no deficiencies could be found. Possible leak area (small leak now, did not show for 6 months) could only be related to metal flashing/roof flashing interface, which right now is frozen together.
I told our site contact that as soon as we have a good break in the weather we would be back to source the leak. She also asked me to check how the drains were, which were exposed and working fine. The client then showed me interior cracks in her ceiling, which with the amount of snow on the roof are more than likely due to extra weight on roof.  She told me their condo board has no money to pay for snow removal and they would take care of it themselves.
Annual Maintenance Follow-up, April 25, 2012: Arriving on site we walked around the building to look for any signs of potential problems ie. open mortar joints and general degradation, and nothing stood out. As we entered the premises interior ceilings and walls did not show any signs of water damage/problems.  Once we proceeded to the roof there was nothing that stood out. Closer examination showed some caulking drying up and cracking. We proceeded to caulk all units/protrusion on the roof and also caulked all seams and screws on the parapet flashing. There were a few minor repairs needed near the scuppers. We used MS Detail to do these repairs. Otherwise the BUR portion of the roof showed no signs of any deficiencies, such as blistering or ridging etc. Once the body of the roof was inspected for these deficiencies we then proceeded to broom the entire roof.  We would level out gravel where the wind around some units would push the rocks away and create a bare spot which would be open to exposure/ UV rays. Then we leveled out the gravel on the entire roof looking for low spot and making sure they were covered. There are only two areas of concern.  The first is the shingles under the scuppers; they are badly worn and are in need of replacement. The second is the gyp rock cover the hatch door. It came off when we opened the hatch, we would have fixed it but it had been re-screwed back on so many times that the edges of the gyp rock were nothing but torn paper. There were several different types of nails and screws around the edge to further indicate it was repaired many times. Roof Report, June 20, 2012:
Removed 18 inches of gravel around vent. The plys are wet and soft so we applied 12" of plastic cement around.
IMAG0271
The ply around the vents were wet, soft, and coming apart.
IMAG0273
12" of plastic cement was applied around the base.
Annual Maintenance Follow-up, January 30, 2014:
An email sent from our project manager to the client:
Hi, Our report, that was copied to you, determined that there are a number of areas of concern that will cause leaks; 1. Areas such as the caulking on the heat stacks (you don't need to call anyone to replace heat stacks) - maintenance issue. 2. Ice damming glacier effect - again maintenance. The previous repairs are not the issue. You have a failed roof that is going to fail in a number of areas at any time, as with this report. When the roof fails the leaks will manifest on the inside at the lowest points, the same points as always because water finds the lowest point in that area and manifests. Did you want a work order to have repairs done? Thanks

Some of the rooftop appliances, such as the base of this heat stack, required re-caulking around its seams.
20140128_151237
Some of the rooftop units also had some tears along the termination bar which required resealing.
20140128_151456
Exposed pocket adjacent to a piece of edge flashing. When ice damming melts, the water has a clear point of entry into the building through sections such as this.
20140128_151422
Ice buildup directly facing an exposed section of the roof edge. We advised the client that without certain parts of the assembly being replaced, water would eventually leak into the building once the snow and ice melted.
