Residential Flat Roof Repair Edmonton, June 9 2015

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.
Below is a sample flat roof quotation. The first link is a PDF download and the second is a Word Doc file download.
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.
 
WORK LEFT TO DO: -patch corners -more turn bar and water block -install and or replace shingles Roughly 6 hours of work left to complete.
MATERIALS USED: -7'x3' piece of EPDM -EPDM bonding adhesive 1/3 of a pail -screws -30 ' of termination bar - 2 tubes of water block -tube of caulking for skylights -half a tube of lap sealer for temporary seals -6 feet of seam tape - quick prime 1/8th of a pail.

May 8, 2015: Residential Flat Roof Repair Crew Attends.
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.

Nisku Industrial Metal Roof Inspection and Repair, July 2012

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.
DSCF0401
The client was the manager of a multi-building industrial site. The first quote he was seeking was for the shingle roof covering the first aid room.
Shop 1 North side
The next quotation entailed maintenance on the north side of the roof for the site's first shop. Our technician quoted for the seams where the metal is joined with the fasteners.
Shop 1 North side (4)
We also provided the details for a snow removal maintenance contract based on the area the roof covered.
Shop 1 North side (3)
The penetrations between the standing seams had been rusting on the metal roof, with some missing or exposed screws running the length of the assembly.
Shop 1 North side (2)
One seam where the metal joined with the fastener was significantly damaged. Rust and calcium chloride had caused cracking and small holes.
DSCF0405
Flashing had been loosely applied to the edge of the shingle roof.
DSCF0404
More loosely applied flashing on top of the roof.
DSCF0402
Although some of the exposed screws on the metal roof were previously coated, there were still many remaining to be addressed. Furthermore, the flashing used on the shingle roof had not been custom-fabricated to fit well with the assembly.
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.
Material Used:
  • 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.

Edmonton Liquid Rubber Roof Replacement, April 2012

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.
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.

  Update (May 30, 2012): We advised the client that roof preparation would commence the following day for the engineered liquid rubber application. Update (May 31, 2012):
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.
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.   IMG_1858 IMG_1859 IMG_1860 IMG_1861 IMG_1862 IMG_1863 IMG_1864 IMG_1865 IMG_1866 IMG_1867 IMG_1868 IMG_1869 IMG_1870 IMG_1871 IMG_1872 IMG_1873      
image-1image-2image-3image-4image-5image
        Update (August 12, 2012): The client reached out to us again that the window is continuing to leak, and that they would like us to look at the flashing  on the roof where the Christmas lights had been screwed into. This recent bout of poor weather saw more water leaking in beyond a spot or two.   Update (August 28, 2012): The crew made it out to the client's location for further, more extensive repairs and safeguarding. They arrived at 9:15, and removed water from the roof, blow drying it clear as well. The capping metal was replaced and screwed down, and a trowel installed to the roof connection. After that, they installed scrim sheeting just before more rain came in. They had to leave the site between 4:30 and 6:30pm due to weather, but returned to tarp the site walls for an over-spray of more liquid rubber. Another coat was started, and the team continued to work until 8:15pm when more rain came rolling in. Tarps were left in place with the client's blessing, and the team promised their return in the morning.   Update (September 19, 2012): Once again, we arrived on location to address the area around the skylight/windows. Our crew member found a few holes and cracking that required repair. They were patched with seam tape and more liquid rubber. This repair took a mere hour and a half; crew departed site after that.     20140918_080905_resized 20140918_080910_resized 20140918_080957_resized 20140918_081004_resized 20140918_091942_resized 20140918_091953_resized 20140918_093327_resized 20140918_093341_resized 20140918_093349_resized   CODE: 4722 Contact Us 24 Hour Emergency Roof Repair.

Edmonton Metal Roof Repair, March 2012

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.

Edmonton Industrial Low-Slope Roof Repair, October 2011

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.   DSCF0446 DSCF0447 DSCF0448 DSCF0449 DSCF0450 DSCF0451 DSCF0452 DSCF0453 DSCF0454 DSCF0455 DSCF0456 DSCF0457 DSCF0458 DSCF0459 DSCF0460 DSCF0461 DSCF0462 DSCF0463 DSCF0464 DSCF0465 DSCF0466 DSCF0467 DSCF0468 DSCF0469 DSCF0470 DSCF0471   CODE: 53030 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
