Edmonton PVC Narrow Roof Repair, September 2015, Edmonton

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.

Many of the seams were also left exposed.

After dealing with the new PVC installation, we began securing new pieces of flashing around the perimeter of the roof. Initially, there had been raised sections which were curling away from the assembly.

Our inspection also uncovered some exposed screws and penetrations requiring new coatings around the base.

PVC Roof Repair Edmonton, June 1, 2015.

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:
  1. 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.
  2. 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.
  3. 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.
Visit our main website for an explanation for flat roofing membrane options and descriptions of each. Below is a short roof report from one of our single ply crews doing repair work for an industrial customer that calls us out regularly. February 19, 2015: Crew Arrives at Industrial Location to Complete Repairs to PVC Flat Roof. 
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.

Edmonton Cedar Shake Repair, April 3, 2013

This client's residential home required replacements to some of the shakes on their roof. Our crew began evaluation on the roof, and determined the appropriate resolution to the client's original concern. The shake roof is 22-25 years old, meaning that some of the shakes start to get soft and porous. Furthermore, the caps start to split, requiring frequent spot-repair/replacements. March 14 Arrived on the job site. Inspected the roof to determine what materials would be necessary for the job. Poor weather conditions; could not proceed March 19 Replacement cedar shakes and jobsite materials were picked up. March 20 Arrived on the job site again, but snow atop the roof and weather conditions deemed the roof unsafe for work. Had to postpone for another day. April 3 Arrived on site for last time. Whole roof checked over and unfit cedar shakes replaced. The caps were also replaced, in addition to the old roof vents. They were of aluminum build, the new ones have been switched out to brown PVC. Lastly, the skylight was recaulked, and checked for leaks.

Commercial Roof Maintenance and Repair in Edmonton AB, January to June 2011

Below you will find a series of reports from the roofing repair crew from the period of January to June for a large commercial client in Edmonton, Alberta. From snow removal to PVC maintenance, the often large time-spans between work is evidenced by weather conditions and their effects on structural integrity. January 22 2011: The entire day was spent shoveling snow in preparation of a leak assessment. Service call, February 8 2011:
Your contact is the facility manager and expects a service call prior to servicing the leaks. Before any future work is performed, a quote must be done unless it is with respect to repairs from shoveling. Note that one of our workers said there is a section that needs repair from a leak that was not caused by our shoveling.
There had been sub-zero conditions in Edmonton that month. We provided the client with an update when the weather was beginning to become favourable. February 27 2011:
As you know, we had temporarily sealed the various points where leakage was occurring as well as spots where we noticed tears. We have also received the Sarnafil that we had special ordered for your site. The next step is to wait the sub-zero weather out and get the Sarnafil patches welded on to permanently seal the deficiencies. In these temperatures that we are currently experience, the cold may prevent proper adhesion. We would rather wait it out than have to come back for another visit. If you need any further clarification, please give us a shout. We will give you a call before arrival, at any rate.
Field Report, March 18 2011: We repaired the leaks right before the afternoon broke out. Any patches that required maintenance were also attended to.
IKEA (2)
We patched over the tears that had accumulated alongside the seams.
IKEA (3)
Closeup of the patch, with some staining around it. The stains are indicative of longterm moisture buildup or standing water.
IKEA
The base of a gas appliance had a few holes as well, which we patched over.
More problems, April 19 2011:
I just got off the phone with the facility manager and he said that leaking has begun again. He believes it is in a different spot, since the leaks are exiting from the carpentry shop about 30 ft. to 40 ft. from the roof hatch.
In the meantime, a PVC repair was also added to the invoice. The weather did not let up until June. PVC Repair, June 1 2011: We called the facility manager and arrived to the facility at 10:45 am. The PVC membrane top-side is damaged in three areas and requires approximately 16 ft. cover strips to repair it. < End Report > Code: IK Call our 24 Hour Emergency Roof Repair at 1.780.424.7663.
