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.
DAY THREE PHOTOS.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. DAY FOUR PHOTOS. 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.
DAY FIVE PHOTOS.
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.
Day Six Photos.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. At the end of the day we put all the perimeter metal back on and spread all the gravel out. We then packed up all of our stuff and down loaded it off the roof to the truck and trailer.

It is a residential roof with a tar and gravel roof that has failed. The crew will be installing a new 2 Ply SBS roofing membrane. May 29, 2014: Crew Arrives on Site to Remove Gravel. The gravel is all scraped in piles. Material is loaded on roof as you can see from the pictures. This roof has bad ponding issues there's only one 4 inch drain on the entire roof and of course the ponding is nowhere near the drain. June 1, 2014: Crew Arrives back on Site. Ripped a 20×40 section. Would've ripped a little more but we ran into some rotten roof, so that delay took some time. It was calling for thunder and rain. Late afternoon. We got rain . Timing couldn't have been better. All sealed up and just got in the truck when the sky opened up. June 3, 2014: Crew Arrives back on Site. Ripped about the same amount today. There is approximately a 25 ×70 ft section left to rip. So as of right now probably 65-70% is ripped off & roofed in. Stripping is on. Cover strips are on. All laps are sealed. June 4, 2014: Crew Arrives back on Site. Today the rain prevented us from tearing off a larger selection than what we did. Another crew came over from their site to help us. They couldn't tear off unless he was going to tear it all off so he came to help us because I can easily seal off what we do on to the existing tar and gravel.

Article: Flat Roof Replacement (Recovery). Commercial Roofing Sherwood Park, Alberta.The roof report below is a commercial roofing project in Sherwood Park, Alberta. It was a liquid rubber flat roof replacement (recovery). We also installed pitch pocket extensions, caps for pitch pockets, and grease trays on the roof. Commercial Roofing Sherwood Park. There were two primary challenges with this flat roof system. The first was that the rooftop units could not be shut down as the restaurant below needed them. And the second challenge was doing roof maintenance with-out removing units in such a small confined space. The decision was made to coat the flat roof with a liquid rubber coating instead of attempting spot repairs. This would enable repairs to be done with-out disrupting the business operation. We also extended pitch pockets, capped pitch pockets no longer in use, and installed proper grease trays so that the grease didn't break down the roof membrane. July 7, 2014: Crew Arrives On Site For Commercial Roof Pre-Install Meeting. Site Location: 194 Ordze Avenue Sherwood Park, Alberta. I met with the client and did a pre-install meeting with him. I took all my measurements for pitch pocket extensions, new grease trays and caps for obsolete pitch pockets. I then went to the shop to get the metal fabricated. They will be done tomorrow late afternoon. This roof might take me two days - there is a lot of prep work and a lot of metal that has to come off and then be put back on to get the job done right. July 8, 2014: Crew Arrives at Commercial Roof Site To Complete Prep Work. When we arrived on site we loaded our tools to the roof and started taking off the loose gravel (which was really excessive and coated in grease). After getting gravel off the roof we spud-ed out about a quarter of the roof but the hotter it got the spud would just wreck the roof so I notified project management of this and our customer. I informed our customer I would be back when temperatures cooled down with in a week or so and customer was fine with this. July 11, 2014: Crew Arrives Back On Site. Today we finally got the roof spud-ed and it wasn't easy but we got it done. After that we cleaned the roof by hand cause I didn't want to use pressure washer on roof with customers walking nearby and vehicles in parking lot. But by the end of the day we got about 50% of our mesh on our detail and all the holes patched the job is 75% complete all that is left is finish around the unit then roll our rubber out and get the garbage off the roof. Site will be complete tomorrow. July 12, 2014: Crew Arrives On Site To Complete Liquid Rubber Recovery. Today we finished our prep work around the units, then we installed our pitch pocket extensions to 6 inch. While Ray and I rolled the roof I had the other guys download all the garbage to the truck to take to the dump. After first coat dried we applied a second coat. Material used. 3 pails of brush grade liquid rubber. Half pail of trowel grade liquid rubber. 1 can Sopra mastic. 120 ft of 6 inch mesh. 4 paint brushes. 2 rollers. August 5, 2014: Crew Arrives To Install Patio Stone Walkway. The crew installed 11 patio stones with high dense foam underneath for a walk way to service units and grease traps.

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.

Residential EPDM and DecTec Flat Roof Replacement to in Edmonton, Alberta.Below is a short roof report from the replacement installation crews that installed EPDM on one of the roofs and DecTec on the other roof on a flat roof residential property. June 12, 2015: Crew arrives on-site to begin old roof tear-off. We started the day with a toolbox meeting and then ripped the roof. The following supplies were picked up from the shop: paint brushes, roller cage, caulking, garbage bags. After we got back we cleaned up and started to replace the wood, framed in the back and the wall tie-in, installed our vapor barrier, then ISO boards, and secured the rock. After it was all screwed down we placed russ strip and started our EPDM membrane installation. July 9, 2015: Crew Arrives to do DecTec in Front of Building. When we got on site to do the DecTec Roofing, we first had to deal with a bunch of garbage from the other roof. So we cleaned up and started on the wall detail. I plan to do this roof with a drip edge and gutter instead of a parapet wall. It will be much easier to deal with the slope and eliminate a lot of details under a wall. But in order to do this I need to have the kick I brought bent at a ninety and order 4 DecTec corners from Calgary. I will also need to get a planer to drop the drip edge area in the plywood. There is a lot of rot around the perimeter and I will have to replace the wall substrate around 1/2 the roof area. I am going to need another 2 days to replace the substrate and a day to install the DecTec. July 10, 2015: Crew Arrives Back To Site. We removed the old roof and wall substrate and floor. We then went to the dump to get rid of the garbage we had. I was going to go to Home Depot for the rest of the materials that I needed but it started raining so I just stopped there for some more poly to make sure no water got inside. We got the poly up in place and it stopped raining so we continued with the working of the trusses. It is rotten right through on the SE corner of the deck and extra time was needed to repair and cut down some of the trusses. We should be ready for new floor and wall substrate by noon tomorrow, at that time we will be at 50% completed. Receipts for job so far. Landfill $27.25. Fuel $116.67 when leaving Calgary. Poly $28.32 at Home Depot. $165.84 at the bolt supply house for screws, bits, counter bits, lock set, sawz-all blades. Approximately $175 at Acklands, can't find the receipt, might still be on the roof. If not I will have to go back to see if they can print out another one for me. For safety glasses, dust masks, cotton gloves, belts for sander, chemical masks, squencher, round sander. zip wheels. I still need approx $400 for 5 sheets for 5/8-4 x 8 select plywood, 1 sheet of half inch plywood, 3 more 2 x 4 s, (1 sheet of 3/8 plywood and 2 2 x 8 from Ravine), 2 putty blades and 6 tubes of construction adhesive. July 11, 2015: Crew Arrives Back to Site. We spent the day replacing the rotten wood around the wall post and repaired the area so that there would not be a problem around the post again. We spent extra time correcting the slope in the SW corner so that water would not want to pond there. We also started on the first run of 5/8 plywood and go half way through lowering the edge for the drip metal to be flush. We still need another full day to complete the floor and wall substrate and install the DecTec patch II. July 12, 2015: Crew Arrives Back on Site. Today we completed the floor substrate so that there is a line of glue under every truss and 2 inch screws countersunk and spaced out every 8 inches. We then installed a drip edge behind the wall substrate and installed the matching wood to the walls. Then we installed metal 90 to the corners that had gaps over a 1/4 inch to reinforce them. Then we installed a metal kick under the patio door and window. Then we installed dec corners and drip edge. We then sanded down the whole area and installed dec patch to the laps. July 13, 2015: Crew Arrives Back On Site. This morning we sanded the dec patch until 10 am, from that point on it was just installing the membrane. We almost finished, I still have some work with the building envelope and weld one spot in the front of the building. We still need to go to home depot and pick up some gutter and ends and brackets. We should everything completed by noon tomorrow. July 14, 2015: Crew Completes Job. This morning we went to site to confirm the measurements for the gutter and went to home depot. When we returned, we installed the gutter and trimmed the rubber at the back of the house. The site is now complete. < End of Report > CONTACT US Call our 24 hour emergency roof repair at 1.780.424.7663. Mail to: 3428 99 Street NW Edmonton, Alberta T6E-5X5.

Article: Roof Repair Drayton Valley. EPDM Flat Roof Replacement. Liquid Rubber Low Slope Metal Roof Repairs. Industrial.This site report is for an industrial location customer in Drayton Valley that requires metal roof repairs on a low slope standing seam roof and a roof replacement on a flat roof that had a PVC membrane that they wanted changed to EPDM. One advantage that liquid rubber has is that we can use it either as a full coating or use it for spot repairs.

Article: SBS Modified Bitumen Torch-On Residential Flat Roof Replacement Edmonton, Alberta.We pride ourselves in quality residential and commercial flat roof repair and replacement. Having quality journeyman roofers ensures our work is always top quality. The following installation report is a SBS Modified Bitumen Torch-On Residential Flat Roof Replacement in Edmonton, Alberta. May 14, 2015: Flat Roof Crew Arrives to Start Re-Roof. 7:30 am arrive on site. We started the day with our tool box meetings. We then set up ladder and brought all tools needed for job up to roof. We started removing the metal flashing from perimeter of roof. We also began shoveling gravel in to rows. Once all the gravel was off the roof, we then started to rip up the old roof. Once we had the old roof half ripped up the trailer was full so we did a dump run. We also stopped at Home Depot to pick up some 5/8 plywood for re-sheathing. Once back on site we filled the trailer again and then swept the roof. We had to re-sheath two areas; one on the east side of roof and one on the south side of the roof. Both were 4 ft x 8 ft sections, so 64 sq. ft. total. Once we had that done, we then layered in our fiber board (FR board). We mechanically fastened the FR board to the roof using screws and plates. I then started torching while the other guys continued to screw in plates and start peal and stick on the perimeter. We managed to get the base sheet done 95%. There is just one small section left to torch (of the base sheet portion). May 8, 2015: Crew attends for day two of flat roof replacement. We got to site and finished torching in the base. Once the base was complete we had to take off the 2 bottom rows of siding because the coating on the back of it was highly flammable. Once it was off, we also had to use peal and stick to seal of the siding so no flames would enter in behind. After this was done we started capping. By the end of the day we got 80% of the field capped. By late afternoon the wind was too strong and kept blowing out torch so we left site at 5 pm.
May 19: Crew Arrives for Day 3 Completion. We finished the roof capping on the field area of roof and started our cap stripping. Once all the stripping was complete, we started our fire watch. We also put all the metal and siding back on. Site is now 100% complete and customer is happy with the work we did.Visit our main website for more information on flat roof replacement.
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.
