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.

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.

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.

Pressure washers were used to clean the surface, which was covered in a mixture of clay and dirt.
20150908_150347
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.

After cleaning the remaining portion of the metal roof, a second team of technicians completed the coatings after preparing the gutter and sidewalls for recovery.
20150909_071809
Various rooftop appliances also required coatings around their bases.

  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.

Ongoing Roof Leak and Drain Repair in Fort Saskatchewan, July 2015

Below you will find an ongoing series of reports for a leak repair in Fort Saskatchewan, Alberta. The site is currently a work in progress. More updates will be posted as they become available. Scope of Work, July 21 2015: Upon arriving on-site, the client advised me about two leak sites - one in the kitchen and one above a light fixture by the washroom. On the roof, there was a major water ponding issue and lack of drainage. There is also a fryer vent that has major dripping onto the rubber. The grease that is leaking out has, over time, started to eat away at it [the rubber]. Structural integrity has been lost, so the next step is to cut out the damaged area and replace it with a 12 ft. x 12 ft. EPDM fixture. The next scope of work would be to install an internal drain, piped in by a plumber. < End Report > Code: 100 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Below you will find a report from the flat roof repair crew. The issue with this roof was that a back-slope was required to get the water drainage correct. Once the back slope was installed on the flat roof the water drained from the roof much better. May 9, 2015: Crew Arrives to Complete Repair

  After filling out our safety documentation and a weekly safety meeting we went up on the roof to find about 2 inches of standing water along the back wall. We spent 2 hours getting the roof dry. Once the roof was dry we then installed our slope with screws and plates to correct the roof ponding issues. After that we put 3 inch seam tape around the perimeter of our back slope. Once that was complete we put latex in our rubber using 2  pieces as one piece. It would of been a hassle after we glued our rubber down. The crew then glued it to the seam tape all around to ensure a 100% seal. The slope turned out really good. The customer inspected the work and was happy. I also noticed 2 outside corners that where failing so I fixed them while I was there we then packed up our tools downloaded them to the truck and left site at 5 PM.

EPDM Membrane Flat Roof Commercial Re-Roof Edmonton June 10, 2015

ARTICLE: EPDM Membrane Re-Roof of Commercial Building Flat Roof Edmonton Alberta June 10, 2015.

The following roof report is of a GRS crew completing a full re-roof on a commercial building in Edmonton Alberta. This roof was 8600 sq. ft in size.  This consists of moving gravel from sections of roof.  Installing a new EPDM membrane to the surface of the roof.  Then covering the new EPDM membrane back up with the gravel. CREW ARRIVES FOR DAY ONE OF THE JOB. 10:00 am arrive on site. Filled out our hazard assessment form, then went up on the roof. We loaded our accessories on the roof with a rope, the main roofing materials were lifted with crane. Once it was all loaded, we started to move gravel on the right side of the roof. My original plan was to remove gravel in a 20' x 50' ft. areas on the roof. I changed my plan and just removed all the gravel from one side of the roof. That way we could just roof all weekend, rather then push gravel again tomorrow.  We managed to get all the gravel from one side of the roof to the other. Now have a nice chunk to roof in over the weekend. 5:00 pm leave site. DAY ONE PHOTOS.

  CREW ARRIVES FOR DAY TWO OF JOB. 7:00 am arrive on site. Had our daily tool box meeting. We then got up on the roof and started to cut the old EPDM membrane out. We Then laid down the new EPDM membrane. The way the lay-out worked was we had to put separate pieces up the parapet walls on the north side. If I didn't do it this way I would of ran into trouble with all the pitch pockets. We manged to put 2000 sq. ft. in today.  Most of the units we had in that area are all sealed in and form flashed on the corners. We did this with four guys. Tomorrow should go better with six. 6:30 pm leave site. DAY TWO PHOTOS.

  WEDNESDAY JUNE 10, 2015 CREW ARRIVES FOR DAY THREE OF JOB.

7:30 am arrive on site. Had our daily tool box meeting. Today we had a crew of six guys working on the roof. So all six of us then got up on the roof. I had two guys start doing detail work while I had two other guys start putting in pieces of EPDM membrane under the rooftop make-up air duct work. This wasn't easy because we could only do 15 feet at a time. The reason for this was we had to jack up the air duct and remove the rooftop pavers. We then had to put them back in once we got the piece lined up my work partner and I were laying the field - which is a lot of measuring and cutting to get the pieces to fit in around all the units. I had a half day on the north side of the roof which is the difficult side of the roof due to all the units and penetrations. We then will move to the south side, which will be easier side because there is very little detail work on that side of the roof. The EPDM membrane re-roof  is 50% complete as of day three.

6:30 pm leave site.

  THURSDAY JUNE 11, 2015 CREW ARRIVES FOR DAY FOUR OF JOB. Today we had to finish the north section of the roof. We had to install the two last pieces of EPDM and roof in around three units. While myself and two others were doing that I had two other guys start gluing up the walls. At 2 o'clock there was a serious threat of rain so it was all hands on deck to get the exposed long lap sealed in around all the posts. We also had gum cups to do, which we managed to get done in just  the nick of time.

  FRIDAY JUNE 12 CREW ARRIVES FOR DAY FIVE OF JOB.

When we arrived first thing in the morning we had to clean up some water from the rain the night before. After that I started on lap sealant where it was required and did a search of all the laps and corners to make sure they were all tight before we put all the rock back on that side of the roof. Once inspection was done we then put all the pavers back where they were before we took them out, we then filled in with gravel. Once the gravel was back in place we then turned our focus to the south side of the roof. We removed  80% of the gravel so we can start to lay EPDM down in the morning. This shouldn't take that long once the new membrane is down. I will get guys on gravel right away while others glue up the walls and start detail work.

Monday June 15th: Crew Arrives For Day Six Of Job.

Today we we cleared off the gravel on the s.w corner of the roof. The area was 20 x 110 feet. Once that was done,  we swept the area off  and laid out our first run of EPDM 10 x 100 ft. Once that piece was all installed I had one worker start the next run of EPDM 10 x 100 ft so he could start on the seams.  I then had another worker start on the walls while I was doing the details around the drain and post. At the end we started to put the gravel back on that section of the roof so we could start the next section the next morning.

  Tuesday June 16, 2015: Crew Arrives For Day Seven On Job. Today we started by moving the rest of the gravel off the SE portion of the roof so we could then lay down the last two pieces of the EPDM membrane. Once all the gravel was moved we laid in the 2 pieces of EPDM 70 ft by 10 ft. Once they were in we installed our seam tape and started our laps on the EPDM. Once the final pieces of EPDM were installed and complete I had a worker finishing the walls and I was finishing all the detail work.

EPDM Flat Roof Replacement Edmonton, June 12, 2015

Article: EPDM Flat Roof Replacement. Residential Low Slope Project.

Below is a site report detailing the installation of an EPDM flat roof replacement in Edmonton, Alberta. The roof was originally a built-up tar and gravel low slope roof that connected to a shingle pitched roof system. Considerations with respect to flat roof systems. When considering flat roof replacement options, it is best to consult experts prior to choosing which membrane you will use, what will make up the roof system, and how the roof assembly will be put together. There are many considerations such as slope of roof, drainage scuppers and internal drains, insulation value, which membranes work best in your climate, what will the effect be on the building efficiency, and much more. All decisions are vital to immediate and long-term success. A flat roof is a considerable expense so you want to be very cautious to make the right decisions.

May 9, 2013: Crew Arrives For Assessment. Flat Roof Inspection.  This is a tar and gravel flat roof that connects to a steep pitch shingle roof. The roof is leaking and has been for some time in different areas. The roof is soft and spongy and there will be some replacement of sheathing and possibly the insulation. The roof is 960 square feet and needs to be re-sloped. The old roof would have to be removed to add enough room for re-sloping.
