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.

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.

Tar and Gravel Flat Roof Repairs Edmonton, June 17, 2015

Article: Residential Tar and Gravel Flat Roof Repairs.

Since tar and gravel was first discovered as a method of roofing, it has been the go-to flat roof  for decades. A tar and gravel roof consists of multiple layers of bitumen and tar.  May 7, 2014: Crew Arrives On-Site for Repairs.  The crew arrives on-site get set up and do a walk around with the homeowner. The homeowner had told me that his roof was leaking and he had tried to fix it himself.  The roof was still leaking. Also, around the back side edge, the metal was starting to lift. I fixed three spots total - one was quite large - 10 ft. x 3 ft. The other leak location was where the metal was lifting, measured at 1 ft. x 8 ft. I refastened the metal and put a gum patch over top.
Flat Roof Repair
To address the first leak location, roofing paper was applied over the membrane. We applied new tar over each layer, building up the roof over each new piece of paper.

Once applied, garbage bags were placed over top to give the tar time to dry.

TPO Roof Repair in Fort Saskatchewan, June 6, 2015

Article: TPO Roof Repair. Flat Roof. Commercial Building. Hotel in Fort Saskatchewan Alberta.

TPO Roof Repair, maintenance, and considerations for type of membranes in cold climates. TPO Roofing or Thermal Plastic Olefin Roofing is a single ply roof system that is used extensively world-wide. In most instances TPO is installed as a white or cool-roof. It can be installed in one of three ways. 1. Fully Adhered, 2. Mechanically Fastened, and 3. Loose Laid Ballasted.  Single ply roof systems came along after tar and gravel and then torch-on SBS modified systems. It's primary advantage is that it is less costly for supply and install than torch-on and tar and gravel due to labor costs. Market acceptance in the USA (or in warm climates) is considerable and the product is effective in those climates. In colder climates, such as with most of Canada, TPO isn't installed as often as the USA and there are considerable studies that suggest that reflective roofing in Canada results in a negative net benefit and that reflective or cool roofing in Canada is prone to condensation issues. Visit these off-site publication links for more information about cool roofing membranes (reflective) in cold climates: 1. Calgary Says No to Cool Roofs. EPDM Roofing Association. http://www.epdmroofs.org/blog/2015/05/18/calgary-says-no-to-cool-roofs 2. The High Cost of White Roofs in the North. Huffington Post. http://www.huffingtonpost.com/charlie-soffel/the-high-cost-of-white-roofs_b_5623273.html?utm_hp_ref=green 3.

Asphalt Roofing Manufacturers Association. http://www.asphaltroofing.org/effects-roof-color-and-solar-reflectance-accumulation-moisture-roof-systems

Repairing a TPO Roof (or any single-ply) Does Have Advantages Over Torch-On and Tar and Gravel.

One advantage that single ply roofing systems have (TPO, PVC and EPDM) is that they are usually quicker to inspect and easier and quicker to repair. As long as it isn't a ballasted single ply roof. If it's ballasted with rock then this becomes a negative and not an advantage because it takes more labour to remove the rock for inspection and repair. Single ply roofing such as TPO, PVC, and EPDM also do not need open flame work such as with torch on modified bitumen roofing. If you get a roofer to work on your 2 ply SBS modified bitumen roof BE SURE they are insured for open-flame work! Also to consider is that torch-on roofing typically requires a more experienced technician than does single-ply and as the years go on there are more and more single ply techs and less that can repair torch-on and tar and gravel. The issues or pro's and con's listed above are why we typically encourage customers that are looking at single ply to install EPDM in a cold climate and not TPO or PVC. The net benefit is a consideration but also is the cost of installation and the cost for repairs and maintenance over the years. October 30, 2014: Crew Arrives To Complete TPO Roof Repairs.  10120 86 Avenue Fort Saskatchewan.
They have a leak in the south-west corner of the hotel. The roof is TPO. When I got up on the roof I picked at all the laps in the area in where it was leaking and on the top side of the slope that would of run through the area and they were all good. I did find a couple breaches in the system. One I fixed with TPO cover strip and the other with water cut off. Personally, I think the leak is coming from the stucco to frame work - there are cracks and holes all through it. Also there is a electrical conduit that runs along the parapet walls which is mechanically fastened and the conduit is attached with 1 inch screws and are popping out - this should be fixed (re-installed correctly or patched correctly) to prevent any further breaches to the system.

Edmonton Commercial Tar and Gravel Roof Repair, Feb 2015

This client had leaks coming through their commercial tar and gravel flat roof. The roof itself is in good shape, but was in need of very minor maintenance.
Table of Contents
Inspection (February 13)
Roof Report (February 21)
Investigation (March 6)
  Inspection: February 13, 2015 The client is experiencing a small leak in the roof 15' away from the front doors, which appears to be originating around an electrical conduit penetration through the roof. The penetration itself is some two feet from the roof edge, which is among the highest points on the roof (drains are in the center). It's believed that the leak could be one of two things. First, it could be leaking around the gum box (which is starting to crack) or second, where the stack is fastened to the roof. To fix the problem, we could first need to patch the gum box, and tighten up the bolts around the conduit and seal the area with some caulking. Otherwise, the 130' x 160' roof is in good shape, and only ten years old. 20150213_093523_resized 20150213_093536_resized 20150213_093608_resized 20150213_093610_resized 20150213_093658_resized 20150213_093707_resized 20150213_093708_resized 20150213_093712_resized 20150213_093740_resized Roof Report: February 21, 2015 The crew confirmed the problem area to be the gum box, caused by a few separate issues. First, the steel pipe had moved slightly under the weight of the wire hanging off the pipe itself. Second, the crew that had installed the pipe and/or roof only filled the gum box one-quarter full of gum and three inches of insulation filler. Over time, the gum began to dry, crack, and settle; allowing water ingress and ponding. The gum box was emptied of the previous solutions and filled 3/4 with pourable sealer, which should now be a permanent solution to the problem. As a precaution, we added a bead of lap sealant around the base of the gum box and a bead of high-quality caulking around the metal support (which had metal bolts going right through the parapet without any sealer at all). IMGP2608 IMGP2609 IMGP2611 IMGP2610 Investigation: March 6, 2015 The client called us to assess the roof once more for three reported leaks in the northwest corner of the building. The roof is an EPDM ballast system, so gravel relocation is necessary to uncover root problems in these types of roofs. We sent out a technician to investigate the causes of these three leaks, for which they found two (need to search under ballast for the third). It would appear that there are two holes in the roof with a near-3" diameter that require patching. The third will be found during repair efforts. 20150306_154607_resized 20150306_155240_resized 20150306_155112_resized 20150306_155105_resized 20150306_154832_resized 20150306_154827_resized 20150306_154753_resized 20150306_154748_resized 20150306_154652_resized This report will be updated with repair logs as they come in.
