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.

ARTICLE: Roof Deck Drainage Problems. Waterproofing a 2 Ply SBS Modified Bitumen Roof Balcony in Edmonton, Alberta.Recommendations for Waterproofing Outdoor Decks Over Conditioned Living Space. Roof Deck Drainage and Waterproofing - Inspection and Repair of a Torch-On Flat Roof on Outdoor Balcony at Multi-Family Condominium. Customers regularly call on us to have roof assessments (inspections) completed. During a roof assessment our journeyman roofers assess the roofs condition. We assess the roof for preventative maintenance reasons as well as inspecting existing problems that the customer is pointing out. We then discuss different scopes of work fix the problems as well as potential materials and costs related to the repairs. One of the most common calls we get for inspections and repairs are rooftop decks, balconies and patios. The primary reason the failure rate on rooftop decks is so high is because of the original installation. It is common for incorrect membrane choice to be the reason. In other words, many people install an outdoor deck membrane that is intended only for an outdoor deck and not a membrane for over a heated living space. If your rooftop deck or balcony is over a heated living area you require a special membrane that is also intended for low slope roofing (as well as deck waterproofing) and is approved for use over a conditioned living space. Common products for this are Dura-Deck or DecTec, both of which are a PVC membrane that are suitable to be walked on (so they do not require a floating deck over top) and they manufacture membranes suitable for over a conditioned living space. We use DecTec extensively and have had great results with it. Or, also common is the installation of a membrane that won't hold up to the foot traffic associated with outdoor living areas. Other reasons include simple age, wear and tear, drainage and issues relating to penetrations or floating deck assemblies on top of the membrane. Visit our main website for more information on rooftop deck waterproofing. This particular inspection and subsequent repairs was more focused toward an aging membrane and the associated repairs that come with not properly maintaining the deck membrane and building envelope over the years. The drainage problems were causing significant damage to the exterior of the building. Below you will find the inspection report.

ARTICLE: Tar and Gravel Roof Repair Edmonton, Alberta. Flat Roof. Multi-Family Condo. Repairs to Scuppers, Edge Flashing Leaks and Entrance Canopy.
Our customer called today for Edmonton roof repair service to one of their condo holdings in the Edmonton area. I have dispatched a journeyman to inspect the roof in accordance to our customer's requests.
Our customer would like a quotation to seal in 5 scuppers using a gum patch method and not torch-on with open-flame. He would also like us to remove all the perimeter metal and fix any spots that are splitting along the membrane with gum patches. When we put the metal back on he would like us to put silicone on the laps of the metal. There may also be entry roof canopy reconstruction involved.
The following site is a condo building in Edmonton Alberta. We were sent here to complete three scopes of work. 1) Flat roof spot repairs around perimeter (remove flashing, repair, return flashing to roof). 2) Fix cracks on edge of scuppers to avoid future leaking scuppers. 3) Fix a canopy roof that was sagging on the front left side.Scope # 1: Perimeter spot repairs on main tar and gravel flat roof.We started the day with the toolbox meeting. Got set up on roof. The roofers started stripping metal flashing around the perimeter while I went and got supplies. We did two different scopes of work on the roof.1st scope was patching around the perimeter of the cant flashing which consists of spraying down asphalt primer on area where patch is needed. Then putting one layer of mastic on top of the asphalt primer. We then put the green mesh on the layer of mastic. The next step in the process is to add one more layer of mastic on top of the green mesh and let it dry. Final is to re-install the roof flashing.
The second scope of work we completed was to fix the scuppers as they had cracks around the edge of them and they were leaking. To do this we screwed each side of the scupper tight against the cant metal. We then put on one layer of mastic on the cracks. We then added the green mesh to the first layer of mastic. Followed by one more layer of mastic on top of the green mesh. This is an alternate method to using open-flame torching.

Roof Report, May 26, 2012:
The crew just called me from subject site. They have torn off the rotted sheathing and found 5 of the 2x4 joists rotted beyond use. What is the protocol here? Do we need to call an engineer? Can we sandwich the rotted joists with new 2x4's (assuming there is anything left to nail to)? If we need an engineer is there someone we use?
Joists can be spliced on either side with simple spikes. However, I need to see photos and need measurements (span of splice) to ascertain the next step of execution. Ultimately the splicing is typically a sister joist attached to either side for full length simply nailed together (unless laminated beams which require bolts). You will need approval in writing for the scope they prefer, waiving of our responsibility to their preferred scope, and the agreement to change order costs which cannot be ascertained until I see detailed photos. Thanks.Roof Report, May 29, 2012: Arrived on site and ripped off a section of the roof. Then we got the plumber set up to install the drains.
