Article: Tar and Gravel Flat Roof Replacement Edmonton to Residential Flat Roof.Below is a brief roof site report from our Edmonton Flat Roofing Replacement crew. 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. We got a 25×25 ft section ripped , covered and sealed up before the rain came. Sky opened up around 4:00 and it has been pouring ever since June 8, 2014: Crew Arrives Back on Site After Rain Had Stopped. Finished up the last of the plate/screw patches. We got a couple runs of cap down. Unloaded unnecessary items like brooms shovels rippers. Materials ; Peel and stick and fr board. June 17, 2014: Crew Arrives Back on Site After Rained for Days. We got all the goose-necks installed right before it started to rain . At least it didn't rain to long or to hard. Considering that there were 13 goosenecks to install. Time consuming detail work. Now roof is completely sealed around every penetration and ready to finish cap sheet. All combined there are 24 penetrations coming up from roof. 13 goose-necks. 9 plumbing vents & 2 drains. (1 full-time drain & 1 overflow) And 3 existing curbs(1 dryer vent curb. 1 gas vent curb. 1 roof hatch). June 19, 2014: Crew Arrives to Install Capping. About halfway done on deck. June 22, 2014: Crew Completes Roof.
Roof is done except the metal.
Everything else is on the ground.
18-20 sheet fiber board.
Propane tanks (3 100 Lbs ).
GRS was contracted by this client to replaced their aging roof. Unfortunately, inclement weather dogged them at every turn, but the team persevered to get the roof installed as quickly as possible.
