This client had GRS come out to carry out some repairs on the narrow flat edge around their home. The technicians affixed the PVC metal to the surface, welded it into place, and sealed everything before leaving the site complete. Roof Report: September 25, 2015 The team went out to the client's site for 8:00am and carried out the hazard assessment before making their way up to the roof. They started down by fastening PVC metal, and one of the crew members worked behind the other to clean it off with splice wash. The third crew member, working ahead of the two others, was cutting the PVC membrane into 6" strips. By 11:00am, they had finished with the metal work and started welding down the strips. Half an hour later the team left for lunch and got some caulking from a local store. Upon their return, one of the crew continued with welding, while the other two caulked around the site and shored up the watertight seals. By 3:30pm, they got the deck rails welded into place and completed the job. All in, 128' of PVC metal was fastened down, and 135' of 6" x 5' strips were welded into place. The job site is now complete, and the technicians departed without any issues. < End Report > CODE: 14003 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Rooftop Balcony Leak Repair Edmonton - Below you will find a series of ongoing reports for a residential client in Edmonton, Alberta. The client requires leak maintenance where a PVC rooftop deck and a tar and gravel flat roof connect and flat roof recovery or replacement to the tar and gravel flat roof. Project manager notes have also been included. This single family home in Edmonton Alberta has a second story rooftop deck (a deck that is over a heated living space is considered a rooftop deck - it needs a membrane suitable for over heated living spaces such as a flat roof membrane). It issue is the homeowners recently purchased the home and came to realize the second story balcony was leaking in to the home causing significant damage. So they hired a deck company to replace the membrane on the deck, but the decking company could not re-connect the balcony membrane to the tar and gravel roof that runs around the house as a skirt. The home-owner asked us to inspect the tar and gravel flat roof skirt and the need for the rooftop deck membrane to be connected properly (the deck membrane that was recently installed is a PVC and the PVC will not of course bond to a tar and gravel roof so a break needs to be constructed and then both the PVC deck membrane and the tar and gravel roof need to be tied in correctly). They also asked us to inspect the tar and gravel flat roof on top of the house. Update (07-30-2015): More posts to come as the work continues at this site. Update (07-30-2015): Quotation added New Client Call, July 24 2015:
- Service: Roofing
- Type: Residential flat roof
- We have small issue with the roof section that joins up with the deck. There is water infiltration culminating in leaks.
- The flat roof skirt that wraps the house which connects to the vinyl deck needs an assessment for replacement options.
- Most recently, there was a water ingress as the previous decking contractor did not correctly set a temporary waterproof scenario where the deck meets the flat roof skirt. An infrared technologist was called in and said there is no considerable issues in the walls, but considering the flat roof skirt's age there may be an issue with rotting joists or sheathing.
- An inspection is required on the connection area between the vinyl deck and the flat roof skirt. Is there a suitable break between the two sections appropriate for us to roof in the skirt properly?
- Inspect the main flat roof above for any maintenance concerns and estimate the expected life-cycle for future replacement considerations.
- Ask the client for the manufacturer name of the vinyl used for the most recent roof/deck replacement. When a roof deck is installed over a heated living space, there needs to be a product that is intended not only for use as a deck membrane, but also as a rooftop (low slope) roof membrane.
- Tie-in new DuraDek material to tar and gravel roof on both ends
- Tie-in DuraDek material to tar and gravel roof and replace tar and gravel roof roundabout. Choose from EPDM, TPO, PVC, or 2-ply SBS torch-on
- Main flat roof on top is not leaking and does not require repair or maintenance at this time.

Article: PVC Roof Repair Edmonton, Alberta. Flat Roof. Industrial. Single Ply Membrane. DecTec.One material available to flat roof (low slope) owners is the single ply PVC roof membrane. The roof report below is specifically a DecTec type of PVC. PVC is an acronym for Poly Vinyl Chloride. PVC roofing is a single ply membrane. There are three different single ply roof membranes typically used in the market. One is PVC, the other is TPO (or thermal plastic polyolefin) and the other is EPDM (ethylene propylene diene terpolymer). PVC and TPO are welded with hot air welders (which would be different than using a torch when installing 2 ply torch-on SBS modified). EPDM seams are not welded using a hot air welder - EPDM is seamed with adhesive. PVC, TPO and EPDM are available in different colors but typically PVC and TPO are installed white and EPDM black. In all three instances (with PVC, TPO and EPDM) the roof membrane is attached to the roof assembly in one of three ways:
- Fully adhered. Fully adhering a roof membrane is the process of using a specialized adhesive to adhere the roof to the substrate or roof assembly. We typically install a residential home this way because it is lighter than ballast.
- Mechanically fastening means that the roofing contractor is installing the membrane with fasteners. Mechanically fastening a system is faster and less expensive than fully adhering it but we tend not to choose this method.
- And finally there are ballasted roof systems. A singly ply ballasted roof is typically one where the membrane is loose laid (seams are either welded or adhered) and then a smooth rock is then installed on top of the membrane to ballast it. Fully ballasted systems are less expensive and quicker to install than fully adhering the membrane, however, when possible we choose to fully adhere the system. After install service is more difficult and more costly with ballasted roofing because it takes considerable time to locate and repair leaks with ballast covering the membrane.
Site address: 1755 Railway Street Edmonton, AB.
Today we had to roof in one roof curb with DecTec PVC. The curb was 18 inches x 40 inches. We had to wrap it with PVC and weld in 4 corners. The only issue we had today was the amount of melting snow. We were repairing and working on a down slope portion of the roof. The melting water was continually running in to our repair of the membrane laps, but we managed to get the membrane dry enough to weld.

Below you will find field reports and project management notes from our Edmonton roofing repair crew responding to maintenance calls for an ongoing commercial real estate client. Maintenance Call, January 20 2011:
Further to the situation at our other property, we have received confirmation that the owner has completed all he can do for snow removal at this site. As per our conversation, we would like a site assessment and quotation. This information will then be forwarded to the owner for a final decision.Post-Repair Report, January 17 2011: There was water in the roof drain, but we noticed the down-pipe was frozen solid. Water was forced out of the pipe near the top of the wall and caused lots of ice to form against it. Ice melt was spread out around the pipe and drain. The drain pipe should be removed and thawed, or otherwise replaced completely. A tenant on the ground floor unit told us there might be as many as four units in this block (northeast corner) that have roof leaks. We should schedule a meeting with the building superintendent so he can let us in to see where they are. January 18 2011: We were shown three other units that reported leaks. Only one on the southwest corner was an actual leak caused by a frozen drain pipe. The leak on the northeast corner that we worked on yesterday has stopped. The owner also inquired about pricing for snow removal. January 19 2011: The owner has advised us that he will be cleaning the snow off the roof himself. Post-inspection indicates that there are many potential issues that will come about during the spring thaw. The roof will like experience failures during this time. The drain pipe should also be replaced. The client called us back a couple of years later inquiring about a roof replacement. We have attached notes from the project manager as well, detailing his recommendations, pros, and cons of each system. Quotation, May 15 2014:
- Complete roof replacement options:
- Spray foam only (+ top coating - polyurea, liquid rubber, or EPDM)
- TPO or PVC
- 2-ply SBS modified bitumen (torch-on)
- 4-ply engineered liquid rubber roof
- TOUGH ROOF
- Sustainable Roofing - Roof Recovery
- Spray foam only (+ top coating - polyurea, liquid rubber, or EPDM)
- TPO or PVC
- 2-ply SBS modified bitumen (torch-on)
- 1-ply coat tar
- 2-ply engineered liquid rubber
- All low slope roof membranes on the market are "good products" - performance depends on who installs the system, the quality of roof assembly components, and geographical area.
- All roof membranes have similar life-cycle expectancy and associated costs.
- All roof membranes will provide excellent protection over many years if maintained properly.
- GRS installs all different system types. Not every roofing contractor can or does install them, so personal bias can play a role in recommendations.
- All low slope roof systems have pros and cons.
- Skylights are not included in pricing unless otherwise noted.
- If structure is experiencing condensation prior to renovation or does in future - a repair, recovery, replacement, or any work done by GRS under this contract is not guaranteed to alleviate condensation issues.
- GRS is not responsible for the structure currently or in future experiencing any deflecting, warping, or settling. GRS is not responsible to assess or advise toward engineering issues. If you have any concern about the engineering of the building, please check with an engineer in advance of any roofing work commencing.
- Due to the nature of low slope roofing and although all care and attention is expected by the crews at work, GRS is not responsible for water ingress that may result during construction or retro-fitting of a low-slope or “flat roof” system.
This project started with an inspection of the client's residential roof as the owner wanted options for replacement. Our project manager provided a comprehensive quotation outlining various options for replacement and recovery. The client wanted options for both the house and the garage. Upon first inspection it was determined that the leakage in the garage was occurring at the flashings, which all need to be replaced. Our crew was informed that a tree had fallen on the rear portion of the garage which is evident from the damage there. The roof itself is not in good shape and has many soft spots, one area even has a foot long bubble on it. There is also a tear about 8 inches long. The inspection of the roof on the house was not quite as bad as the garage; however, there was one soft spot located around the drain. It is possible that the insulation underneath is beginning to saturate with water. Normal blistering on the roof is evident of the roof coming to the end of its life. The flashing is also an issue with one hole caused by the adjacent tree. The client is open to all available options. The following is an email sent by our project manager to the client providing a quotation for various roofing options:
Good morning, Please find attached the pricing you requested. Both your home and garage is priced. The documentation and internet links in the attached report detail our; Workmanship Guarantee, System Options and Methods, Credentials, 2011 Schedule Availability, Links to Manufacturers, GRS Project Portfolio and Clients, etc. There are two different methods to do your roof, one is to rip the old roof off (a complete replacement) and the other is a new Roof Recovery System. A Roof Recovery has our crew scraping the gravel off, taking the old membrane and soaked insulation off (as required only) and then mechanically attaching a fibre board and then putting a new roof over top (SBS Torch On, Tar and Gravel Mop On, EPDM, TPO, or PVC per quote). Typically a roof recovery is what is done. A roof recovery is less intrusive, it is more environmentally friendly as the old bitumen layers don't end up in the land fill, the old system also has an inherent R Value of usually around 7, it is less costly, and the life-cycle is the same as a complete replacement. However, if you find that you want or are required to completely remove the old system down to the substrate (the sheathing or metal Q deck), we can accommodate this and the pricing is included in the attached documentation also. Additionally, there are a number of different membranes available, which I've detailed in the quote. Essentially, it comes down to 1) A traditional 4ply mop on tar and gravel (BUR), 2) 2ply SBS Mod Bit (torch down or cold apply), or 3) Single ply; black rubber membrane (EPDM) or a white membrane (TPO or PVC) depending on whether you want to draw the sun in or not. EPDM, TPO, PVC are available in multiple colors, however EPDM out of the box is typically black and TPO / PVC are typically white. Single ply systems are what are being installed more and more now (for GRS singly ply is about 80%), however, we install all system types. I would encourage you to consider the life-cycle costing and maintenance / repair benefits of a single ply system prior to choosing a system. Have a read and let us know what you think - I know there is a lot of information so I'm sure you will have questions. Thanks for the opportunity to quote - it is appreciated!
