Below you will find a series of ongoing reports for a client in Edmonton looking to re-roof their building with an EPDM system. The building is a low slope duplex, where the entire roof would receive treatment with the new surface. Continue reading EPDM Roofing Replacement, July and August 2015, Edmonton
Article: Residential Flat Roof Repair Edmonton, Alberta. EPDM Low Slope Roof Membrane.Repair of an EPDM low slope roof on a residential home in Edmonton, Alberta. The low slope (flat) roof transitions to a pitched shingle roof. Penetrations and challenges include chimney, skylights, vents, drainage, ice damming, and insulating value on low slope. Additionally the transition between the low and steep roof systems posed challenges. Also a section on choosing the correct low slope membrane and roof assembly. This customer had originally called us when Edmonton had set records for snow-fall in January of 2012. She had significant snow loads on her roof and the concern was that her roof may collapse. So we removed the snow from her roof and discovered significant ice damming challenges on the low slope portion. We returned in 2013 and 2014 to do regular roof snow removal because every-time the snow built up on the roof the heat from inside her home would get to the underside of the low slope roof sheathing and cause ice damming. The ice dams would then get in between the laps of the existing roof membrane and result in leaks. Mid 2014 she contacted us to quote on the replacement of the low slope roofing with hopes of solving the problem. We quoted the various options for low slope roofing membranes, which included; Spray Foam (SPF), Tar and Gravel, SBS Torch-On, EPDM, TPO, PVC and Liquid Rubber. Our standard quotations include pricing for the different options available for flat roof system membranes, a roof inspection report, a write-up on the pro's and con's of each type of system and our recommendations for your most suitable roof membrane choices.
Our customer chose to replace her failing tar and gravel built up roof with an EPDM single ply membrane roof recovery (or retro-fit). This means that we removed the gravel and skinned the bitumen membrane off and then mechanically fastened a roof board and then fully adhered the EPDM. We also did some drain work and scupper work. Our customer did not opt for a complete removal, re-sloping with an engineered slope insulation system, or any additional R value added which could also have been done with simple rigid type insulation boards. In early 2015 our customer had called with leaks to the low slope membrane - the ice dams were back. This is an important lesson in choosing the correct roof membrane, insulation, drainage, re-sloping and more. Had we been able to re-slope the roof and been able to add insulation value, the heat from the inside of the home would not escape and get to the underside of the roof membrane and cause ice damming. But, the customer requested the least expensive options and even though our reports (see link above for sample quotation and inspection report) explain in detail most considerations, this is the way it was requested to be done by the customer. So this spring we returned to find the same ice damming causing issues with a now new membrane. We also found drainage issues which were expected - the roof was ponding because a re-slope was not in our scope. And there were some technical (debatable) installation tweaks that may or may not have been required. Nonetheless, we now had a new roof leaking the year after it was installed. So of course we once again suggested the upgrade options to alleviate the issue but the customer would have nothing with that and requested we simply do the repairs and move on. Below is an account from the crew of the type of repairs they did to try and mitigate any issues in the future (full well knowing that the prime aggravating factors are insulation value and sloping). May 5, 2015: Crew Attends to Residential Flat Roof Repair. We arrived on site at 9:58. We started the day with the toolbox meeting and safety documents. We then went up on roof to determine an installation plan. The scope of work we decided on and did is as follows. Scope of Work # 1 The first step was to pull all EPDM down to flat roof from under the shingles at the bottom of the sloped roof. This reinstall was to ensure no water could be coming from the flat roof to steep pitch roof transition. We then had to remove all metal flashing from around the two skylights and chimney on the roof. Once we had all the EPDM pulled we started lifting shingles along the first few rows of the sloped roof and applied the EPDM bonding adhesive. This was done under the first couple layers of shingles and to the underside of the EPDM. We then installed the EPDM back under the shingles. Then next step was to apply a bead of water block on the edge of the EPDM under the shingles. Once that was complete we secured EPDM by screwing a piece of turn-bar down on the edge of the EPDM where the water block bead was applied. Scope of Work # 2 The crew arrived on site at 1 pm and started working on the cricket behind the chimney. He started by cutting a piece of EPDM 7'x3'. He then had to take the Epdm bonding adhesive and apply in the same manner as the work in scope # 1 by applying the adhesive under the shingles as well as the under side of the Epdm. Once the 7'x3' piece was installed he started working on the corners. Using quick prime and seam tape he seamed in the corners of the Epdm around the chimney.Below is a sample flat roof quotation. The first link is a PDF download and the second is a Word Doc file download.PDF. Sample Flat Roof Quotation Including Roof Inspection Report and Pricing for Flat Roof Options, Edmonton, AB
We started at 7:30 AM with a daily tool box meeting. We then got up on the roof and started shoveling snow away from work area so we could complete today's scope of work.
Scope #1. Scope one consisted of applying corner patches to the rear corners of the chimney. The next step was to apply tape primer to the EPDM surface on the corner of the chimney. We then cut 6"×6" squares of 6" covers strip to use at the corner patch. We applied this piece on top of the tape primer and let it sit to cure. Scope #2. Install termination bar for the EPDM on the front of the skylights. For this we measured and cut a piece of turn bar to fit the front side of the sky light. We then screwed (mechanically fastened) the termination bar. Scope #3. We had to take the bottom two layers of shingles off and replace with new ones. For this we had to carefully lift the bottom rows of shingles and pry out the nails so the shingles would slide out. We then took the new shingles and installed them. This consisted of laying down the first layer and nailing in place. The next step was to put on the second row of shingles which slid under the old existing one and nailed in place half way down the first shingle we layer down. Job is complete.
-2 bundles of shingles
-8'of turn bar
-2' of cover strip
- tape primer

Our project manager provided this client with a quotation for various options including complete roof replacement, liquid rubber coating, and temporary repairs. This report outlines an inspection as well as a minor repair that followed. Inspection, July 1, 2012:
This client would like a quote to repair the first aid room. The roof is very poorly shingled and the slope may be too low for shingles. Take note of the large loosely applied flashing in the pictures as this is likely part of the problem. There are several avenues to take but a journeyman should have a look first. The breezeway has no problems. Shop #1 is still leaking. We repaired all penetrations very well. We discussed coating the straight line where the metal overlaps and is bolted together. It is 152' long and we likely will need to use scrim as the opening is quite large in some places. He would also like a quote for maintenance on the north side of the roof on shop #1 (which was not in the scope during the last round). It is 152' x 52'. I think we should quote on the seam where the metal is joined with fasteners at the same time, as he wants that quoted for the south side of that same roof, again 152' long. He would like a snow removal maintenance contract for the winter as well.
Roof Report, May 21, 2014: I met with the client and he showed me where it was leaking. I noticed that the area where the down pipe meets the roof wasn't sealed, so I took it apart and sealed it using LR and water cut off.
I also spotted a few possible leak spots which I fixed just in case they were causing issues.
- 0.5 of a pail of trowel grade liquid rubber (LR).
- 0.5 of a pail of roll on LR.
- 1 tube of water cut off.

This post reflects the field reports of a GRS crew attending to a client's re-roofing request. At the onset, it would appear that they would like to explore Tough Roof or a liquid rubber system.Update (June 1st, 2012): The crew returned to the job site for ~10:00am and continued pressure washing the roof and preparing it for the spray-on liquid rubber. They departed again for 2:30, having completed the preparations. Liquid rubber was then applied to the roof in what is called a 'flood coat'. The crew cited that the single coat was appropriate, and that another wouldn't be necessary. Update (June 13, 2012): The client called us to advise that a leak had developed at the skylight and that regardless of rain quantity, it appeared 'random' in how much water would seep through, and at what rate. The leak began after the Christmas lights were removed from the screw-in fixtures atop the window capping. The responding team went back up onto the roof and determined that the caulking around the windows was correctly applied. They concluded that there was no damage to the roof or fault in the liquid rubber application; the leak must be a problem with the window itself. CODE: 4722 Contact Us 24 Hour Emergency Roof Repair.

The homeowners at this location are in the midst of a complete remodel and are looking to eliminate all problems with their roof. Though smaller repairs could be made, it looks like they would like to replace the roof outright. After explaining the systems available to them, they appear most interested in Tough Roof or a liquid rubber system.Scope of the Work:
- Sealants and tie-ins are dried, non-malleable, and cracking.
- The drainage appears to be good. No clogs, No pooling.
- The parapet walls consist of capping only.
- Building structure interior and exterior appear solid
- The current tar and gravel roof is splitting - there is no sponginess. Blistering was found in 2 areas, with the larger of the two nearly punctured.
- Christmas Light holders have been screwed into the capping above the windows, this will have to be replaced.
After picking up some equipment from another job, the crew arrived on site for 9:20am, ready to begin preparing the roof for liquid rubber application. The gravel had to be removed first, followed by a thorough power washing to remove all possible debris from the roof. This took up the bulk of the day, but they received some extra assistance between 3:30 and 5:30 from another pair of crew members after they'd completed another job. Everyone on the main team departed at 6:30pm.
The details below cover a metal roof repair for a client's industrial building in Edmonton. Multiple sections of the existing roof are leaking, and they reached out to us for a quotation to put carry out the necessary repairs. The client reached out to GRS for a quotation for the several repairs necessary for their building's metal roof. After examining it, we found six problem spots that would need to be addressed (Shop 1, First Aid Room, Four units on upper level). We returned the desired quote to them, in addition to replacement and liquid rubber options for the lower roof, should they consider that avenue of approach. We advised that the best option for the failing roof would be a engineered liquid rubber application, as metal roofs swell and shrink with temperature changes and are prone to failures of that nature more than any other system. The liquid rubber stretches with the metal, and would be the best bet to have the leaks dealt away with. Repairs were carried out to the problem points, but the failing metal roof sprung more leaks that could not be guaranteed against in the initial repair attempt. We offered re-roofing or roof replacement services at a discount, but the client requested quotations for repairs to other areas of the roof in addition to a snow removal maintenance contract for the upcoming winter. Post will be updated as more information comes in. CODE: 2103 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663. Mail to: 3428 99 Street NW Edmonton, Alberta T6E-5X5.

The below is a summary of repairs carried out at an industrial business in Edmonton, AB. Having a low-slope roof with apparent water ingress, the client reached out to GRS to provide quotation on temporary repairs or re-roofing the entire system. Our team went out to the client's location to perform an assessment that might be used in a quotation for their roofing problems. We found that the low-slope roof had six penetrations, several of which were damaged (either bent, or losing their seal). It appears that they had already attempted a temporary fix with some tape, but the seams were wearing through already. Inside the warehouse there were some cracks in the ceiling that needed examining, and there was some minor concerns regarding the gutters (slightly askew). We photographed the location and provided quotation for temporary repairs or roof replacement services. The client elected for the repairs at this moment, so we scheduled a time for our crew to return to the site. Update (October 19, 2011): With the work order submitted, we sent one of our crew members back to the warehouse to perform the spot repairs on the roof. The entire repair took just over three hours to complete, and required minimal materials to carry out. CODE: 53030 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
