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.

EPDM Roof Restoration with Liquid Rubber Coatings, September 2015, Edmonton

GRS first carried out an inspection and some light repairs on this commercial building's EPDM roof in April of 2012. There are two roofs in this system, one EPDM and one metal. We began working on the roof in September of 2015, proceeding with an engineered liquid rubber coating, on top of repairing any new fault areas that have developed since then. Check out this page for the original inspection information, though it may be referenced in some sections below.
Table of Contents:
Inspection
Scope of Work
Roof Reports [all 2015]
  Inspection: April 17, 2012 The original inspection is very thorough and worth reviewing. In summary, the EPDM and metal roof was suffering from some puncture holes, leaks, and membrane degradation. The structure itself is sound, but could use some maintenance to address then-current and future problems. Spot repairs could be carried out, or the roof could be recovered with a new watertight system (ie: liquid rubber).   Scope of Work: September 7, 2015 The crew made a list of things to present to the client, covering all of the pertinent safety information and everything needed to demonstrate that the scope of the project has been thoroughly considered. Below is a copy of everything they were prepared to cover.
Required on site to show HSE Manager:
  • GRS tool box documents
  • MSDS (attached)
  • WHIMIS tickets.
  • First aider with ticket
  • Fall arrest tickets
  • First aid kit
  • Pylons and caution tape for 6' control zone
  • Harnesses and ropes
  • Proper safety glasses
  • Steel toe boats (with green triangle symbol)
  • Long sleeve shirts
  • Gloves
 
Other:
  • Liquid rubber - 15 - 17 pails
  • Rollers, sleeves, brushes
  • Seam tape
  • Flashing mesh
  • Pressure washer, hose, electrical - be sure to advise office staff that roof may leak while washing.
  • Rags (materials to dry roof)
  • EPDM repair materials and tools
 
Notes:
  • Access to roof is with roof door - walk out on roof. Do not use ladders to access roof.
  Scope of Work:   Roof 1. EPDM ballast roof restoration. Approximately 36' x 50'
  • Remove rock ballast from half of EPDM roof
  • Wash EPDM roof membrane to white-glove clean
  • Repair EPDM as required
  • Coat half roof with liquid rubber (about 900 sq feet or 3 - 5 pails)
  • Return ballast to EPDM roof
  • Remove rock ballast from other half of EPDM roof
  • Wash EPDM roof membrane to white-glove clean
  • Repair EPDM as required
  • Coat half roof with liquid rubber (about 900 sq feet or 3 - 5 pails)
  • Return ballast to EPDM roof
  Roof 2. Metal Roof Coating. Approximately 56' x 50' Details first. Wash roof and/or internal gutters as required. Dry. Reinforce all your details with liquid rubber and/or seam tape or mesh as required before rolling out or spraying liquid rubber. Check all fasteners and replace as required or coat with liquid rubber. Check all rooftop penetrations, flashing, roof-to-wall connections, roof eave to gutter area, internal gutters and sheet metal connections, internal gutter to wall connections, and seams (especially horizontal) that may be separating. Clear old caulking etc. Add seam tape or mesh with liquid rubber. Coat complete metal roof, in gutters, and up parapet walls 30" in liquid rubber. Be sure to tape off a clean line at wall at a height of 30" or so - the line needs to be clean and straight. Pay close attention to internal gutters especially where sheet metal connects and where the internal gutter is at a vertical meeting the metal roof edge (that's where most leaks on these systems occur).

  Roof Report: September 8, 2015 The team met in the morning for a brief safety meeting with the entire crew present. They then went up to the roof to begin moving the ballast from the west side onto the east side, preparing the area for cleaning. Using pressure washers to clean off the surface, the team found some difficulty with the amount of clay mixed in with the dirt. They sent one of the technicians out to pick up more scrub pads that could handle the tougher soil. Heavy rain began rolling in, so the team had to depart a little bit early. Half of the roof is cleaned off and prepared for the following day's application of liquid rubber. Plan for September 9: Arrive for 7:00am, and put down the first layer of liquid rubber on the now-complete half of the roof. While it cures, the second half of the roof will be prepared for the same.

Scrub pads were used to remove the remaining soil. After the roof was dirt-free, we gave it a final wash.
20150908_150404
We had to shut the site down when heavy rain began to roll in. Half of the roof was cleared and now prepared for liquid rubber applications.
    Roof Report: September 9, 2015 The GRS crew arrived on site for 6:45am, and had their toolbox meeting for fifteen minutes until the client arrived to grant access to the roof. They began by clearing off the residual moisture and prepared to apply the liquid rubber to half of the EPDM roof. In the meanwhile, the other part of the team was at the shop picking up another six buckets of the liquid rubber solution. By the time they'd returned, the first team kept cleaning the metal roof. Half of the metal roof had liquid rubber applied to it, and the technicians kept preparing the gutter and sidewalls for recovery. Once the west side of the EPDM roof had cured, the crew moved the ballast back from the east side. They kept preparing and cleaning the east side for tomorrow's application of liquid rubber, as some rainfall prevented them from more liquid rubber application. Both the EPDM and metal roofs have been half-completed with liquid rubber, with the other half prepared for the following day's work. The customer also reported a heavy leak, which was traced and temporarily patched until it can be addressed at-length.

  Roof Report: September 10, 2015 Work began on the roof around 6:45am, where the team got to cleaning the EPDM roof in preparation for more liquid rubber. Everything was cleaned and prepared for 10:00am, and after a brief coffee break one technician got to applying the rubber solution to the ribs of the metal roof while another applied it to the EPDM. The two remaining crew mates finished up the mesh and detail work on the metal roof, working through 12:30pm until lunch. Resuming at 1:00, they all continued with their assigned tasks until the metal roof was done around 3:00pm. The EPDM roof has a 5' x 36' section still requiring ballast removal, cleaning, and liquid rubber application. It's expected that the work will be finished tomorrow.
20150910_081808
After clearing the ballast rocks from the other half of the EPDM roof, we again had to wash off the clay/dirt mixtures from the surface.
20150910_101401
After washing the detritus, the surface was nearly ready for liquid rubber coatings. Scrub pads were used to remove any remaining buildups. One 5' x 36' section of ballast was still remaining, as well.
20150910_101450
Concurrently, another technician applied coatings to the remaining metal roof's ribs.

    Roof Report: September 11, 2015 The crew arrived on site for 7:30am, and got to cleaning the remaining section of the EPDM roof. By the time they took a break around 10:10am the roof was clean and ready for the liquid rubber. They performed a leak test on the second roof, and made sure that there was no water ingress to the offices below. Once confirmed, they prepared the breather holes on the metal roof's ribbing with mesh and rubber. Lunch break went from 11:30 - 12:00pm, and the EPDM roof was finished shortly after. The rubber has to cure before the ballast can be replaced, so the team moved on to the metal roof to continue adhering the mesh and rubber to the ribbing. Come 2:40pm, they had the site cleaned up and marked the job complete. < End Report >   CODE: 6621 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
