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.

Normally when we attend to flat roof repairs, the goal is to either perform repairs that have a high probability of lasting for some time or replace the roof. In some instances, our customers do not have it in the budget to either do the repairs properly or replace the roof. Often they have a replacement budgeted for the future. In the instance below the customer wanted the least expensive option to simply stop the leaks until he/she could finance a roof replacement. A quote for much more extensive repairs was provided but declined. January 20, 2015: Crew Arrives On-Site To Complete Repairs. Originally the client had one leak on a goose neck vent.

Article: 2 Ply SBS Torch-On Low Slope Roof "Gum Box" Repair on Commercial Roof in Edmonton Alberta."Plastic pan - also called pitch pan, pitch pocket, gum box, these comprise a flanged collar placed around items that project through the roof system; the flange is properly set into the roof membrane and the pan is well filled with plastic cement; these pans are a constant source of trouble and should only be used when no other solution can be found." Source: Red Seal Roofer Program Website. February 13, 2015: Journeyman Roofer Attends for Roof Inspection. Address 11754 170 Street Edmonton, Alberta. The client is experiencing a small leak 15 feet in front of the front doors around an electrical conduit penetration in the roof. The electrical conduit is two feet from the roof edge which is the highest point on the roof as the drains are in the center. I believe the leak could be leaking around the gum box which is starting to crack or where the stack is fastened to the roof. I believe the water is getting in through those holes and running back into the system. To fix this problem we would need to first put a gum patch on the gum box and tighten up the bolts on the bracket that holds the conduit and seal around it with some good caulking. Man hours 3 - 6 total with drive time and inspection time. Material 1 - 3 gal pail of gum. 2 tubes of tremco chalking. Roof measurements 130 ft x 160 ft with two drain and 13 penetrations. The roof is approximately 10 years old and in good shape.

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: 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. May 20, 2015: Journeyman Superintendent Attends for Balcony Inspection. Roof Inspection Location: 10245 116 Street NW Edmonton Alberta. Roof Inspection Date: May 20, 2015.

Article: 2-Ply SBS Modified Torch-On Roof Replacement High Level, Alberta. Low Slope Commercial.Torch-On Roof Replacement. 2-Ply SBS Modified Low Slope Commercial Roof. SBS modified torch-on roofing is one of the more widely used flat roof membranes in Alberta. I don't know the industry wide percentages, but I would venture to guess that we install about 30% of our roofs with torch-on. EPDM would be about 45% and the other 25% would be a mix of the other types listed below. When replacing a flat roof your primary options are traditional tar and gravel, 2 ply torch-on, single ply membrane (TPO, PVC, or EPDM), spray foam (SPF) or some form of fluid applied. Visit our local Edmonton roofing division website for a more detailed description of the various flat roofing membrane options. For torch-on, common application methods are conventional roof systems and inverted roof systems. In the manufacturing process modifiers are added to standard roofing asphalt to replace plasticizers removed during a distillation process. Bitumen is then reinforced with fiberglass or polyester fiber matting in order to increase durability and strength. SBS (styrene-butadiene-styrene) increases the flexibility of the membrane and allows it to have stronger expansion and contraction capabilities - the synthetic rubber additives increase flexibility of the membrane. Modified bitumen roof systems can be installed with torch, fluid applied asphalt, or cold adhesive. A typical SBS modified bitumen roof system (as in site report below) is a two-ply application applied with a torch using rolls of membrane that overlap the edge of the previous roll. In the example below the roof board (or fibre board) is what we refer to as an FR Board and it has the base sheet SBS applied to the fibre board before leaving the factory. In this instance the base sheet FR board is mechanically fastened to the roof deck with the cap sheet being torched on after. The benefits of 2-ply SBS modified roofing are:
- Torch-on SBS modified roofing is very durable. This is important for high traffic roof assemblies. This would include commercial or industrial roofs where there are perhaps a lot of rooftop units, satellites, communication towers and the like and various service technicians attending to the roof regularly.
- It is weather resistant and can handle impact that perhaps other membranes would have issue with.
- It is moderately easy to repair and maintain.
- The factory manufactured rolls make quality control easier than with tar and gravel BUR roofing.
- It is moderately flexible. This is important for climates such as Canada.

There is a leak where the two roofs on this commercial property join. 30 feet from the front of the building in the area where the leak is the SBS modified torch-on cap sheet stripping is significantly cracked and losing life. There are about 3 inches of ice across the roof and 2 inches of water under the ice. To fix the roof leak we will have to clear off a section of ice and pump the water off the roof. Once the water is off the roof we then need to dry the area so repair work can be done. We then need to de-granulate a 16 foot section of stripping and torch down new SBS modified stripping to seal in the roof and repair the leak. This roof is very old and needs to be replaced asap.Man hours to complete repairs. 18 to 20 with fire watch and drive time. 1 - 2 rolls of modified bitumen cap sheet (frost grey in color).
