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.

Industrial Roof Liquid Rubber Repair, October 2015, Stony Plain

This client's industrial building required some repairs to the ridge line capping. They contracted a team of GRS technicians to go on-site and carry out the repair with liquid rubber.   Roof Report: October 7, 2015 The team went out to the client's location for just the afternoon and wrapped up the metal and seam work that had been left from a previous day (report currently unavailable). They also applied the engineered liquid rubber solution over half of the roof's ridge, but had to shut down the site around 3:30pm when the wind picked up. With so much dirt and dust blowing around, it would've been unwise to carry on applying the liquid rubber. With the site shut down, the crew departed, set to return another day with more cooperative weather.

Residential EPDM Roof Replacement, October 2015, Edmonton

This client's home bears a low-slope roof that they wished for GRS to replace with an EPDM system. The crew of technicians went out to their location and completed the roof replacement in two days' work.   Materials List: October 13, 2015 Two technicians went out to the client's location and inspected the roof for what kind of deficiencies might be encountered during the roof replacement. During their inspection, they noted down the expected materials that would be required for the job.
  • 2x Rolls of EPDM
  • 7x Pails of EPDM bonding adhesive
  • 1x Pail of primer
  • 1x 6" roll of form flash
  • 2x Pipe boots
  • (84) 4' x 4' sheets of fiber board
  • 4x Roller cages and sleeves
  • 1x Box of seam tape
  Roof Report: October 16, 2015 The team arrived on site for 8:00am, and had their disposal bin arrive by 9:00. At that point, they were already underway ripping off the old roofing system and making good progress. It was after then that they found that there was no plywood with the order, just 2x6 boards. They departed to get the requisite plywood, and returned an hour later around noon. The boards were all mechanically fastened into place, with some of the EPDM laid atop it. The crew departed in the early evening, set to return the following day and focus on the remaining EPDM and metal flashing.

Commercial EPDM Roof Replacement, October 2015, Saskatoon, SK

This client in Saskatoon contracted GRS to send out a crew that could replace their currently flat roof with a new EPDM system. The team went on location to rip out the old system and installed the requested EPDM without any issue.   Roof Report: October 7, 2015 This day, the crew arrived on site for 7:00am and began to rip off the existing roof system. The other team members didn't arrive until a short while later, right around the time that the crane showed up with the site materials. Between 12:30 and 12:45pm, the team loaded the roof and found that the order was missing insulation and seam plates. The site lead had to leave the site then, to pick up the missing supplies. By their return at 3:00pm the remaining team had torn off enough of the roof to expose some rotten plywood underneath. This too, had to be replaced, so another member of the crew was dispatched to pick up some replacement sheets. In the meanwhile, the on-site crew put down the ISO insulation boards and began gluing the rubber to it. It was around that time (~5:00pm) that the temperature began dropping below what the normal threshold for the glue's application permits, so the team weighted down the EPDM for the night and prepared the site for the rubber's adhesion the following day.  
20151007_124904
We started the roof replacement by ripping out the existing system. The roof surface consisted of plywood boards.
20151007_152321
Some of the plywood boards on the roof were rotted to a point where there were holes in the assembly.
20151007_181009
Damaged pieces of plywood were replaced and we prepared to install ISO over the structure.
20151007_185222
Bonding agent was applied to the underside of the EPDM and installed over the ISO boards.
    Roof Report: October 8, 2015 The crew assembled once more for 7:00am and got to ripping out the rest of the roof as the sun began to rise higher into the sky, warming up the site. When the roof itself was all torn out, they laid the EPDM's ISO insulation and then adhered the rubber atop it. This work carried on through the day, so that by the time they were prepared to leave the site, all of the rubber had been laid down and some of the plywood had been installed to the parapet walls where it had required replacing. The following day would only require some detail work to some curbs and seams. They expected that everything would be completed by 3pm and the site would then be entirely finished.    
20151008_170637
After ripping out the existing structure on the second half of the roof, we mechanically fastened ISO boards.

      Roof Report: October 10, 2015 The crew finished the roof on this day, but not without a little bit of trouble during the process. One of the subcontractors hired on for the job was not able to carry out the metal work that they'd claimed, so a replacement had to be found on short notice. The replacement arrived on site and completed the metal work in a timely fashion that also measured up to the exacting standards on any GRS project. With the metal work done, the site was cleaned up and the crew departed, leaving this another completed site bearing the GRS stamp of approval.
20151009_174044
To wrap up the site, we finished the metal work, including the perimeter flashing.

Liquid Rubber Roof Repair, September 2015, Sherwood Park

This client's flat, metal roof required some patch work with liquid rubber. GRS sent out one of its technicians to carry out the quick repairs over the course of a few hours one day.   Roof Report: September 29, 2015 The three technicians began their day at 7:30, travelling to the garage to retrieve a trailer and some materials. Once loaded, they went out to the client's location and arrived around 10:15am. The technicians inspected the leak and subsequent water damage on the roof and loaded the work area with brushes and liquid rubber that would be suitable to this type of repair. They applied meshing to the expansion joint (approximately 25' long) and began applying liquid rubber to the new seam. Unfortunately, some rain rolling in hindered progress, but the crew took an early lunch and waited for the sun to break back out and help dry up the work area. All said and done, the crew was able to finish up the liquid rubber application by 2:00pm and depart the client's site without any problems arising to necessitate their return.

Metal Siding Leak Inspection, September 2015, Edmonton

This client's commercial building bears a flat metal roofing system, but contacted GRS over some concerns that the metal siding around some windows on the upper level had leaked. GRS sent out one of its technicians to inspect the area and provide some advice on the repairs that could be carried out. Inspection Report: September 29, 2015 The technician went on-site and met with the client to discuss the problems with water ingress around the windows on an upper level of the building. They went out to the metal roof and began inspecting the windows and surrounding walls. The leaking areas became quite apparent, and the whole wall could use some patching. The reporting technician then suggested that every window's corners be treated with caulking to divert the water away from the metal edges. This is due to the water's current path, which is to run along the metal and behind the wall. Their estimate was that two crew members would be on-site for a half-day and use around eight tubes of caulking to properly seal the areas. This would, however, be a 'bandage' approach; the proper way to fix the problem would be to first remove the metal around the windows, cut back the wall metal, apply seam tape or spray foam between the metal and the wall, then replace the flashing that has degraded to this point.  
20151013_151528[1]
The client reported water ingress around the windows on the upper levels of the building.
20151013_151531[1]
While the sealant used around the sill had failed, and parts of the metal roof required patching, our technician suggested caulking applications around the corners such that it would divert water away from the existing coatings.
20151013_151556[1]
Here is another example of a portion of the window where water was forming pockets. The rusting is characteristic of water pooling for extended periods of time on the sill, and slowly leaking into the building over time.
20151013_151631[1]
There had also been some tearing at the end of the drip edge on the top of this window. Water had been entering through this hole.
WP_20150929_14_46_20_Pro
Some tearing in the metal siding on the roof had also been another potential leak entry point. The tearing had reached a point that the siding was becoming loose from the wall.
WP_20150929_14_48_39_Pro
Some components also required re-caulking around the base. Cracks in the old sealant had created small holes through which water could enter.
WP_20150929_15_05_58_Pro
There were also windows which had missing screws. Water had been entering the building through the screw holes.
WP_20150929_14_59_46_Pro
Another example of a piping penetration requiring sealing.
WP_20150929_14_59_28_Pro
While our technician was willing to apply a "bandage", the correct approach would have been to spray around the affected areas with foam or seam tape, and then reinstall new flashing.
WP_20150929_14_56_50_Pro
After addressing the windows, we did some water testing around the perimeter of the roof walls to make sure that the seams were watertight.

Edmonton PVC Narrow Roof Repair, September 2015, Edmonton

This client had GRS come out to carry out some repairs on the narrow flat edge around their home. The technicians affixed the PVC metal to the surface, welded it into place, and sealed everything before leaving the site complete. Roof Report: September 25, 2015 The team went out to the client's site for 8:00am and carried out the hazard assessment before making their way up to the roof. They started down by fastening PVC metal, and one of the crew members worked behind the other to clean it off with splice wash. The third crew member, working ahead of the two others, was cutting the PVC membrane into 6" strips. By 11:00am, they had finished with the metal work and started welding down the strips. Half an hour later the team left for lunch and got some caulking from a local store. Upon their return, one of the crew continued with welding, while the other two caulked around the site and shored up the watertight seals. By 3:30pm, they got the deck rails welded into place and completed the job. All in, 128' of PVC metal was fastened down, and 135' of 6" x 5' strips were welded into place. The job site is now complete, and the technicians departed without any issues.
WP_20150925_10_38_29_Pro
Our scope involved installing PVC metal to narrow flat roofing which ran the perimeter of the house.
WP_20150925_10_38_35_Pro
The metal was fastened by one crew member, followed by a splice wash application by another. Leading this process, a third technician cut and laid down 6" strips of PVC, which was welded on.
WP_20150925_10_38_59_Pro
The original roofing assembly had missing screws throughout the flashing, and blisters in the membrane.
WP_20150925_15_17_53_Pro
Many of the seams were also left exposed.
WP_20150925_15_21_46_Pro
After dealing with the new PVC installation, we began securing new pieces of flashing around the perimeter of the roof. Initially, there had been raised sections which were curling away from the assembly.
WP_20150925_15_18_42_Pro
Our inspection also uncovered some exposed screws and penetrations requiring new coatings around the base.

Spray Foam Roof Repair Request, September 2015, Esterhazy SK

This client in Esterhazy, SK had some problems in 2014 after a big storm. The third-floor rental units of this building had some water damage then, but none since. They reached out to GRS to find a local roofing company that specializes in flat roofs. Our project management worked with them to begin scheduling a team to come out from Regina or Saskatoon. Request For Service: September 24, 2015 The client called in to GRS to see if any roofers could make their way out to the small town of Esterhazy, SK and inspect their roof to see what might've caused water damage in the rental units below a year prior (July 2014). There have been no reports of further water ingress since, but their insurance company required that the roof be attended to before they can proceed with the claim. With Esterhazy, SK being so far away from major centres of operation for GRS, scheduling was a little bit difficult, so the project manager sought as much up-front information as possible about the site and the state of the roof before dispatching crew to go on-site. Submitted Photos: September 25, 2015 The client sent in photos that show the state of the roof and what kind of system the GRS crew would be dealing with upon their arrival. In doing so, it ensures that everybody handling this project with GRS understands what would need to be done in order to correctly patch the roof without any excess travel time such a distance from Regina, where the repair team would be departing from.

The foam joining the roof and the edge flashing was exposed up to the downspout. Water had not been draining correctly, which also culminated into leaks.
  Correspondence: September 25, 2015 The project manager receiving these photos noted the poorly state of the roof system and asked how long ago it was installed. The client responded that it had been installed in 2008 by a Spray Foam company. In dealing with these types of failures, it's important to consider if the system is under warranty or not. Most of the systems and materials that GRS installs on flat roofs come with 20-40 years of expected lifetime and warranty coverage. The project manager relayed this information to the client, as the repairs could be covered by the company that performed the original installation, or the material manufacturer. The client then located the paperwork from the 2008 installation and found that their roof bears a 10-year warranty against leaks. It was at that point that the GRS  project manager advised returning to the original roofing company and advising them of the problems with the structure. The client heeded the advice, and the service request was then closed. < End Report > CODE: 1000 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
