Commercial Tar and Gravel Flat Roof Leak Repair Edmonton, November 2015

Below you will find a routine leak repair service call for a commercial client by our Edmonton roofing repair crew. The following reports underline some of the work we do with other contractors and trades, such as plumbers.  Inspection, November 19 2015: We began to sweep the rock layer on the flat roof to expose the surface so that we could start looking for leaks. After speaking with the building manager, our crew has been asked to wait for a plumber before we inspect the drains. The second part of our inspection entails what units need to be removed.

The client was the owner of a multi-residential apartment unit.
20151119_135416
We started by sweeping away rocks on the flat roof to look for the potential causes of water that was leaking into the building.
20151119_135419 Roof Report, November 21 2015: Today the crew removed more gravel from the roof. A couple leaks were patched up. The site manager gave us the go-ahead to remove one unit from the roof. Roof Report, November 23 2015: Today we shoveled more rock from the roof to find more holes that needed patching. Once it started snowing, we covered the roof and shut down the site.
20151123_120414
We eventually found a few holes throughout the roof that needed patching.
Roof Report, November 25 2015: We removed the one unit that the building manager had requested to be taken off-site. We also started working on two drains but were later informed that the owners were having all the pipes replaced, including on the other two drains that we were not given permission to begin work on. The remaining two pipes were added to the work order and we will have to wait until they have completed the pipe replacement before proceedings.

We removed a unit off-site at the building manager's request and patched over it.
Roof Report, November 26 2015: We are still waiting for the plumber so that we can proceed with the inspection and maintenance on the remaining two drains. This site should be completed on Saturday. Site Completion, November 30 2015: We finished the site today, on schedule. The remaining two drains were replaced, which we had to add to the original work order. Another possible leak location was sealed. As well, any metal that we removed from the walls was reinstalled. Another rooftop unit was disposed of, as well.

Edmonton Commercial Flat Roof Replacement, January 2015

This commercial client in Edmonton was presented with a quotation for a flat roof replacement. The report follows the crew as they performed the replacement over the course of several months. Scope of Work:
  • Scrape gravel down to existing 4 ply membrane and take down to dispose.
  • Supply and glue down a FR board (1/2 inch fiberboard adhered to a 95 gram sanded poly sheet) and seal all laps.
  • Supply and back torch a 180 gram armour bound peal and stick up walls and all penetrations.
  • Remove and replace any wet insulation.
  • Owners to move and re-position satellite and communication systems.
  • Clean all debris and haul away.
Roof Report, January 21, 2015:
We arrived on site at 2:10 pm and I got set up to continue with the cap stripping. At the same time we were waiting to see what was going to happen with the weather since it was still drizzling. I went through the safety paperwork and then we helped with removing the garbage from the roof and brought it to the bin. 20141212_14051920141212_195820 20141212_195807 20141212_140503 Roof Report, January 23, 2015: After our toolbox meeting we proceeded to install FR board on the upper mechanical roof and did so until the point of satellites in all directions. We then installed peel and stick stripping wherever possible and sopramastic waterproofing in all other protrusions.
Cleaned up and left site at 4:30pm.

Roof Report, February 12, 2015:
This morning after we were done with the safety reports, we went to the upper roof and continued with the base seal tie in. I had two other crew members remove snow from the entire upper roof while I started to install peel and stick on the curbs. After I was done with the curbs on the north side of the roof, I installed patches over the plates and installed gussets were there were none. I also found several spots that needed patches in the field and repaired as required.
Roof Report, February 14, 2015:
Started to lay in FR board where they moved the satellite towers. Once we got the base done on one I had a crew member start capping it in while myself and another crew member started to base in the next section. Both sections were capped by the end of the day which made the client happy. Then I stayed on site to complete fire watch.
20150214_013512_resized 20150214_022441_resized
Roof Report, February 18, 2015:
This morning we started on completing the NE corner of the roof by installing the last of the FR board. We also started sealing around the curbs and perimeter.
We then moved to the SW corner and completed the base tie in around the satellite and patched plate holes in the area. Fire watch from 3:30pm to 5:30pm.
IMGP2516 IMGP2517 IMGP2518 IMGP2519 IMGP2523 IMGP2527 IMGP2532
Roof Report, February 19, 2013: Once we got to the site we continued with the base tie in around the large curb and the parapet on the SW corner of the upper roof.
Roof Report, March 7, 2015: Today we completed the field cap and most of the DE granulating around the details. Roof Report, March 9, 2015:
Bill and me completed the cap stripping on the upper roof today and need to touch up the gum boxes and granules to finish the SBS on the upper roof. We then completed the curbs on the main roof and started to install the plumbing vents when it started to rain at 3 pm. I am not happy with the large ponding area on the east side of the main roof and would like permission to extend the sump on the east side with a trough through the high spot so that more water drains.  I would have to cut out the FR board from the sump about 1 ft. wide west about 10 ft. to where the water ponds 3 inches at the deepest point. Then tie in the old roof to new torch on roof through the trough. This would require 10 man hours and another roll of cap which would add another 2 years to the life of the cap in that area. Roof Report, March 10, 2015:
Today we installed 8 plumbing vents and touched up the existing plumbing vents with smag and granules. We completed the west drop drain install and reset the air units on the SW corner of the main roof. We then cleaned the entire main roof and downloaded all the garbage. Roof Report, March 11, 2015:
This morning we completed the touch ups on the gum boxes of the upper roof and then started installing the metal around the perimeter of the upper roof and found that we were short one length. On the far east side of the roof there looks to be another piece missing that would cover the electrical lines and 2-18 inch storm collars are gone as well. We installed all the metal that was there and added extra screws and smack pins to make them very solid.
Roof Report, March 12, 2015: After the weekly meeting in the morning we met up at Home Depot for caulking and then went to the site. We spent extra time on resetting all the wire tracks on the upper roof and finished off the storm collars with caulking as well. 2 of the 18 inch stacks still have no storm collars but we filled them with caulking anyway. With no metal flashing on the wall detail on the upper roof, we made sure that water would not pond there by completely filling the riglet with caulking. We downloaded the rest of the tools, rolls of base, and propane into the small trailer and parked it in the very NE corner of the parking lot.  The bin is still on site and will need to be removed.
Follow-up Inspection, August 19, 2015: Upon visual inspection of the roof. I noticed 6 different blisters had developed. Attached is a copy of a roof map that shows the approximate locations of the blisters. Continuing on we walked the entire roof, testing the membrane to make sure the insulation was properly adhered to the roof underneath. I would say that there is no issues with the adhesion. The following is a list of the repairs that should be made to said deficiencies:
  • A lack of chipping away at the existing roof that was re-roofed led to a ridge. We can either build it up around it, leveling it off, or cut it and patch it.
  • Run a patch to meet lapping requirements.
  • Pipes need to be patched.
  • Anchor fasten the flashing correctly to the wall. Ms detail to seal the flashing.
  • Replace with concrete paving stones and roof mate underneath, and have a drainage mat under the roof mate.
  • Run a drainage mat or roof mate.
  • Install storm collars and caulk them.
  • Have a flashing made up and installed.
  • Have a sheet metal cap fabricated and installed.
  • Install cap sheet, roof mate, drainage mat and paving stones.
  • Box it in with cap and quick prime.

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.

Materials Needed:
  • (1) 6x6 scupper.
  • (10) 100' dark brown downspout.

Roof Report, April 24, 2014: Today we fixed the down pipe and installed an elbow. When I went to install the scupper box I called our project coordinator and he said it had to be a torch-on tie in. The roof was still wet from the previous rain so we are going to leave this until the roof has dried. I notified the customer of the schedule change due to water on the roof and she was okay with it. 11 image Roof Report, May 8, 2014: We installed one scupper with a torch-on tie on to the BUR roof, and I also had to modify the metal where the scupper was placed. There was an uneven balance to the roof so we put more rock on the places where it was needed. When finished with the scupper I had to fix the down pipe that was connected to it and where the down pipe hits the ground. This site is now complete. 0 1   4 5 6  8 9 < End Report > CODE: 13104 Contact Us Call our 24 hour emergency roofing repair at 1.780.424.7663. Mail to: 3428 99 Street NW Edmonton, Alberta T6E-5X5.

Edmonton Commercial Temporary Roof Repairs, August 2013

This condominium in Edmonton required temporary roof repairs to mitigate water and wind damage. Several areas of the rooftop had missing shingles and a full inspection of the building was requested by the client. Temporary repairs are needed to prevent further water damage inside the units. Inspection, August 12, 2013: This location has severe wind damage as out lined in an earlier correspondence with the client.
  • Specific to temporary repairs ordered, the area is approximately 10sq. of wind damage on 4 unit building (#64-#67).
  • Above unit 65 was hit worst.
  • Temporary repairs affected to 65 and others on block unit.
  • No visual hail damage on vents or any metal.
  • This is a 3 story back side and 2 story front side.
  • The pitch is approx 6/12 with some being 5/12.
  • The IKO brand shingle and product number A40490 color is weather wood.
    Further observation of complex:
  • Shingles missing and fascia and siding damaged to units 1 – 8, 24, 50, 80, 83 and 134.
  • While working on unit #65 I could see that there was wind damage to unit #83, unit #50, as well as unit #10 (photos taken). I added 4 shingles while up there to stop the water from entering.
  • Unit #50 & #10 I was unable to tend to them due to extreme weather conditions - they have similar areas as unit #65.
  • Unit #128 was missing a piece of facia.
  • Unit #138 was missing a a couple pieces of imitation cedar shake siding but there was no roof damage to this unit.
  • There is a serious mishap with the nail lines for this complex, every area that has blown off has the nails too high – installation of shingles will not meet manufacturer recommendation.
Additional Notes: The nails weren't long enough. The shingles discussed earlier were not nailed on the paint line. As well, the manufacturer has the seal line too high allowing wind to get under them to lift up and then blow off. What we need to do is take full measurements which will take quite an amount of time because some areas don't have access unless on a scaffold. I think it would take 2 days just for measurements. Measurements are better done from satellite.

Edmonton Liquid Rubber Roof Replacement, September 2012

This commercial client had various water leak issues on his rooftop including water ponding which had damaged the membrane. The roof was a candidate for the replacement or recovery option and the client decided to go ahead with a full liquid rubber replacement. After two inspections the following emails were sent between our project manager (italicized) and the client:
Good afternoon,
After our second and more thorough inspection, GRS feels it would be in your best interest to do a Full Roof replacement over Recovery.
A Recovery (retro-fit, overlay, re-covering) involves covering an existing flat roofing system with a new roof membrane. This process requires removal of all wet, damaged, or deteriorating roof insulation prior to the new roof being installed.
The main concern with a Recovery System is that your roof is currently leaking and the large amount of ponding water. This means the roof membrane may be totally damaged and a Full Roof replacement will suit you best.
In addition, when the current roof membrane has been saturated 30% or more we typically suggest a full roof replacement.
After our second inspection, we estimate that the roof is most likely saturated at around 15%.
At this level of saturation we can still proceed with a recovery system, however if we miss any insulation that is saturated, with the Liquid Rubber Recovery over top it creates condensation and the Liquid Rubber will bubble and possibly crack. If you decide to do a recovery system, we may have to come back for a few repairs meaning you may have future leaks. In the end it is more of a on-going problem for you and us. These visits will be free of charge as our recovery systems warranty applies.
For full roof replacement we still encourage our 4 ply Engineered Liquid Rubber System as we have had the most success with the product.
Today, customers trust significant roof asset management, repairs, and projects to GRS which include some of the largest commercial and industrial roofs in the world.
What sets us apart is an industry leading Lifetime Workmanship Guarantee and our commitment to core values. Old-fashioned hard work, customer service and honesty, customer education, superior property stewardship, an unwavering position toward safe work, and a passion for pinnacle roof craftsmanship are examples of values we hold. These build trust with customers, a strong company culture, and great character in roofers who enjoy a job well done. Any further questions or concerns I will assist you as you require.
 Thanks for the Consideration! Greatly Appreciated.
 General Roofing Systems.
Hi, I guess we need to proceed with a roof replacement with liquid rubber. Is this possible this year? Thank you.
Good morning, The 4 Ply Liquid Rubber Roof Replacement is strongly recommended. Great choice, the Liquid Rubber Roof is our most successful membrane.
We can complete this roof this year. Do you have any other questions? If you decide to carry through with this scope of work I will compile a work order for you to sign. Thanks for the consideration.
Initial condition of the rooftop: 1 2 3 4
Plumber's Report: Friday we had a plumber and mechanical technician attend the site to disconnect and move AC units and to lower the drain for adequate drainage of the roof.
The plumber informed me that the acting drain on your roof was actually the main vent for all your plumbing and could not be used as a drain as this does not adhere to the current building code. There is going to have to be a new drain installed on your roof to bring the roof up to code. We can finish the roof and install the drain once we are complete or at a later date but this leaves your roof without adequate drainage and could potentially create large problems. If you would like us to proceed I will get a quote from the plumber and a change order will have to be processed outlining the costs and will have to be approved and signed by you prior to the drain being installed. Our Journeyman red-seal roofer has informed me that upon the event of a flash flood/torrential downpour water will inevitably reach the flashing level and at this point water will seep into the roof system, causing the roof to fail. Thank you.
Roof Report, September 13, 2012:
  • Ripped off roof and cleaned it.
  • Removed skylight and put it back on again after taking off the sheet metal and flashing.
  • We put plastic cement around the vents.
  • Put on ice and water shield.
  • Job will be 100 percent done in another 2 days roughly.
Today a safety officer showed up at the job site and asked for the safety documents. Mike was there and he handled the situation very well, The safety officer asked us to install hooks to the roof for each person who is going to be working on the roof. We did what he asked for and he inspected to see if it was done proper. We were given the okay to carry on with the job. Roof Report, September 16, 2012: Materials dropped off on site in the morning and half of the ISO was already removed. After lunch all of the ISO had been removed and the crew was beginning to install the fiber board. Once half of the fiber board is down, one of the crew members will begin laying fabric. We should be at the spraying point by 4 or 5pm today. If the LR install is complete tonight the only thing remaining will be the re-connection of the AC units and the duct work. The new drain is to be put in on Monday pending the customers decision. A second coat may also be applied if necessary.
  • Laid and mechanically fastened ISO to entire roof area 5 screw and plates per 4'x4' sheet.
  • Coated ISO and backside of fiber board with liquid rubber for installation.
  • Installing fabric with rolled on LR (fabric 80%).
  • Patched holes in field temporarily with fabric and highbuild 200.
  • Attempted to spray but ran out of daylight.

Roof Report, September 17, 2012:
  • Finished 20% of fabric and rolled on LR.
  • We put high-build and mesh underneath flashing.
  • We put fabric and high-build around curbs.
  • LR coating on the entire roof.
  • Installed plumbing vents and roof jacks.
AC units and electrical are not connected. Plumber will be on site tomorrow to do the plumbing part. HVAC is not connected (duct not hooked back up). photo (1)photo (3)photo (4)photo (5)photo (6)photo (7)photo (8)photo (9)photo (10)photo (11) Extra Costs (associated with AC units): Our project manager sent the following email to the client:
Hi, I am writing this email to inform you of extra costs incurred on the project. Due to the age and positioning of the AC units on the roof they had to be completely disconnected and moved to install the roof system properly. Also while our mechanical contractors were on site disconnecting the AC and electrical, they requested they lower the drain on your roof to allow for adequate drainage. The plumber informed us the drain in current use was not a drain at all but the main vent for the plumbing of the building. Vents being used as drains is no longer accepted and is contrary to current building codes. This being said to bring the roof up to code and to be able to put the roof under warranty the drain simply had to be installed. I will get a change order for the additional costs sent over from our office for you to sign and send back, just sending this email as a courtesy to explain the extras so you don't feel in the dark. Thank You.
Roof Report, September 18, 2012:  
  • AC units connected and placed in original position.
  • Proper roof drain was installed.
  • Perimeter cant was brushed with highbuild 200 and meshed.
  • Entire roof was coated with brushed on LR.
  • AC units duct work reconnected.
  • Temporary anchor screws were siliconed and left as there was no drill on site.

Edmonton Commercial Flat Roof Inspection, August 2011

This report follows an initial inspection for a commercial client requiring a roof replacement. Also included is a correspondence sent to the client by our project manager. Inspection, August 19, 2011: This roof is accessible by hatch. The current roof system is tar and gravel and is experiencing multiple leaks. Upon inspection I found approximately twenty blisters, numerous spots of surface erosion, and sealants cracking around vents. The client would like a quote for replacement. He will be removing the outside lighting which is set on the parapet walls, but would like us to remove the satellite dish.
The following email was sent to the client by our project manager:
Good morning,
Please find attached the pricing you requested, sorry about the delay - if there is any problem opening the attached let me know and I will resend in a different format.
The documentation and internet links in the attached report detail our; Workmanship Guarantee, System Options and Methods, Credentials, 2011 Schedule Availability, Links to Manufacturers, GRS Project Portfolio and Clients, etc.
Beyond attempting repairs, there are two different methods to do your roof.
One method is to rip the old roof off (a complete replacement) and the other is a new Roof Recovery System.
A Roof Recovery would have our crew scraping the gravel off, taking the old membrane and soaked insulation off (as required only) and then mechanically attaching a fiber board and putting a new roof over top (SBS Torch On, Tar and Gravel Mop On, EPDM, TPO, or PVC per quote).
Typically a roof recovery is what is done. A roof recovery is less intrusive, it is more environmentally friendly as the old bitumen layers don't end up in the land fill, the old system also has an inherent R Value of usually around 7, it is less costly, and the life-cycle is the same as a complete replacement.
However, if you find that you want or are required to completely remove the old system down to the substrate (the sheathing or metal Q deck), we can accommodate this and the pricing is included in the attached documentation also.
Additionally, there are a number of different membranes available, which I've detailed in the quote. Essentially, it comes down to 1) A traditional 4ply mop on tar and gravel (BUR), 2) 2ply SBS Mod Bit (torch down or cold apply), or 3) Single ply; black rubber membrane (EPDM) or a white membrane (TPO or PVC) depending on whether you want to draw the sun in or not. EPDM, TPO, PVC are available in multiple colors, however EPDM out of the box is typically black and TPO / PVC are typically white.
Single ply systems are what are being installed more and more now (for GRS singly ply is about 80%), however, we install all system types. I would encourage you to consider the life-cycle costing and maintenance / repair benefits of a single ply system prior to choosing a system.
Have a read and let us know what you think - I know there is a lot of information so I'm sure you will have questions.
Thanks for the opportunity to quote - it is very much appreciated!

Edmonton Commercial Metal Roof Leak Repair, August 2011

This report begins with a quotation outlining various options for a metal roof repair. There is moisture entering the building and leaking which is occurring after rain and snow falls. There also appears to be a number of maintenance issues with the existing sheet metal. Roof Observation Report: Very difficult to pinpoint where the moisture is entering, however it appears to be coming in at a number of areas. The metal roofing has a number of maintenance/sheet metal issues but the inherent expansion and contraction also likely causes issue. This roof leaks after the snow melts and heavy rainfalls. The roof is approximately 25 years old and could use a metal roof replacement but the Engineered Liquid Rubber coating will stop the roof from leaking for many years. Project Manager Recommendations (emailed to client):
This roof structure is a candidate for either a repair-maintenance program or an engineered coating and does not have to be replaced. I would not recommend an elastomeric coating or the SPF Spray Foam as the acrylic and EPDM covering options do not last well in Edmonton climate, but liquid rubber performs well in our climate. Generally speaking, metal roof systems are constant aggravating roof structures. Industrial metal roof systems have a deficient design - they are water-shedding and not water-proofing coverings. Metal expands and contracts more than any other roofing material. Metal roofs tend to leak from expansion and contraction and ice / snow loads. Leaks are intermittent at seams, penetrations (stacks, etc.), fasteners (fastener holes get larger with expansion and contraction), around the perimeter as ice back-ups at gutters and then under eave, and at joints between roof and wall connections. Metal rust / corrosion may start at places, the seams and fasteners are vulnerable from expansion / contraction and snow loads, and any traditional caulking or coating won’t last more than a few seasons at best. Remedies are either spot repairs-maintenance with caulking or more extensive maintenance which involves engineered coatings. Our recommendation is a high end engineered liquid rubber polymer coating that carries a 10 Year Manufacturer Warranty and has option for maintenance contracts for extended warranty. General Roofing is considered a pioneer and leader in engineered roof coatings; (www.liquidrubber.ca, https://www.grscanadainc.com/Roof_Coatings.html, https://www.grscanadainc.com/Liquid_Rubber.html). We have significant liquid rubber operations specifically serving industrial facilities with low slope metal roofs. Our clients include companies such as Imperial Oil, Shell Oil, Telus, Fortis, Toran Power, National Oil Well Varco (NOV), Teck Resources, and many more.(https://www.grscanadainc.com/Project_Portfolio.html). In this instance, we recommend a 2 Ply System engineered liquid rubber coat to complete metal roofing, fastener replacement as required, sheet metal repair as required to-achieve a water-tight state. Typically this is even more successful than a full metal roof replacement. A recent project with photos can be found at; http://generalroofingsystemscanadainc.blogspot.ca/2012/05/roof-repair-liquid-rubber-metal-roof.html Thank you.
August 16th, 2011: The crew arrived on site and found two pipe boots and two patches that were leaking. Also discovered were two large holes in the membrane of the north corner (also causing leaking). It appears that something heavy had dropped on the roof at some point causing the holes. The insulation around the two holes was totally saturated and this was clearly allowing quite a bit of water into the system. The insulation is acting like a sponge and is releasing water into the Q deck and lunch room of the building. The crew performed a drip count within the three areas where dripping was occurring. The first drip count was done before the flood test and the results are as follows: Area 1:  every 10 seconds. Area 2:  every 6 seconds. Area 3:  every 19 seconds. After the repair and during the flood test the results were as follows: Area 1:  every 16 seconds. Area 2:  every 20 seconds. Area 3:  none.
The test indicates that the repairs were successful and that there is a slow drip only because of the still saturated insulation. The crew also searched the rooftop for any other possible leak spots. One area was found and patched. It was further reported to the client that the A/C unit in front of the roof hatch was dripping water from inside the unit.
The client was highly satisfied with the execution of the repairs.
DSC01206
Two large holes in the membrane were found, and the insulation was completely saturated with water. Water had been entering the building through these holes and leaking into the lunch room.
DSC01207
We moved the ballast rocks around the piping systems and other roof appliances, checking for deficiencies. The coatings around the base of this drain were past their life cycle.
DSC01209
Second tear location. Although this section of the roof had previously been patched over, some heavy object had fallen and caused the hole.
DSC01210
The torn off EPDM was tucked back into place, with new liquid rubber coatings applied over top.
DSC01211
Coatings completed on both tears.
DSC01212
After the coatings had cured, they were patched over with new EPDM.
DSC01213
Finally, caulking was applied over the seams to make the new patches watertight.
DSC01216
We found some other old patchwork that had been provided in past spot repairs. Some of them had been coming apart, although no water had been entering the building through these sections.
DSC01217
There were a few other patches along the perimeter of the roof that we also identified as requiring touch-ups.
DSC01218
Liquid rubber coatings and spud at the seams were applied over these patches to mitigate leaking in the future.
DSC01219
Water had been dripping from inside of the A/C unit into the roof structure.
