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.

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.

Athabasca DecTec Balcony Assessment, February 2015

Our client, located north of Edmonton, reached out to GRS to explore the option of installing DecTec Membrane on a balcony off the second floor of their building. Scope of Work: 1) Removal and disposal of existing roof assembly under the existing membrane that would interfere with new surface installation. 2) Removal/replace rotten sheathing (if any). 3) Mild increase to slope to encourage drainage. 4) Door openings may have to be customized to account for new slope. 5) Flashing may have to be re-done to accommodate new slope as well. 6) Deck railing removed and replaced to ensure safety. 7) Waterproofing of walls to allow for vertical installations. Ensures watertight fit. 8) Upon completion of 1-7 (as necessary), floating deck can then be installed to support viable systems (SBS Modified Torch, EPDM, TPO, or PVC), though DecTec does not require a floating deck to sit atop the membrane.   Proposed Solution DecTec bore GRS's recommendation for this project, as we employ all of the technicians typically required to see a successful installation. The client was simply looking for a quote for this type of project, which we were happy to provide.   Existing Decking: Pre-DecTec Installation 1 Pre-DecTec Installation 2 Pre-DecTec Installation 3 Pre-DecTec Installation 4 Pre-DecTec Installation 5 Pre-DecTec Installation 6     Until next time,         The Roofers at GRS CODE: 4510 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Rooftop DecTec Installation, March 2014, Edmonton

This client's residence bears a flat roof with a leak in one corner of the tar and gravel system. Upon GRS' inspection, however, the client desired to explore options for a total roof replacement and its conversion into a rooftop deck.

Edmonton Rooftop DecTec Installation, December 2013

The report below follows repairs made to this client's residential roof deck. They sought a DecTec installation, replacing the existing system with one to be more reliable. Unfortunately, the in-progress roof reports' photos are no longer available; the placeholder image above is another project of GRS' that illustrates a similar roofing system.   Inquiry Received: September 9, 2013 When we first heard from the client, they told us that their deck is built right into the roof (as a cutout), and the flat floor seems to have leaked. It appears that their previous repair job was not done properly, and they had worries that there would be more existing issues that had not yet been discovered.   Quotation Delivered: September 11, 2013 After hearing about the situation, GRS project management delivered a quotation was for roof deck repair and/or replacement options. We booked them in for service, set to repair the problematic areas.     Roof Report: December 7, 2013 Given the temperatures and snow buildup, the technician began their time on site by bringing up the heater to warm up the deck. By raising the temperature of the decking surface, it would be better prepared to accept the patching material. While the deck surface was warming up, the technician planed and sanded the deck joints to give a flush connection. At that point, the servicing technician installed the deck patch to alleviate problems with the reported leaking. They went over the next steps with the client, letting them know that the existing slope of the deck is moving water into the drain nicely. The rest of the job should be completed the following Monday with the DecTec installation. The GRS technician waited for the deck patch to set and dry in place. They put together a plan for the scope of work yet to be completed; details below.
  • Sand the deck patch down.
  • Cut the plywood on the walls to a height of 6", as the old membrane will not come off the walls and there is a gap from where the deck was lowered.
  • Replace the removed plywood with 1/2" plywood boards.
  • DecTec to then be installed.
  • Must then install peel-and-stick membrane to the door frames, power outlets, and lights in the area.
  • The vapour barrier must also be installed where needed.
  • The handrail, which is currently in a rotten/poorly state, will need to be removed and replaced with a new piece of lumber (2" x 8" x 12')
  • Install more peel-and-stick membrane to the top of parapet walls and the new hand rail.
  • In Spring 2014, Hardie Board and metal trims can be installed. It may be able to be done sooner, as the product doesn't need to be painted.
Unfortunately, the photos for this site are unavailable - please accept our apologies!   Roof Report: December 10, 2013 The GRS crew arrived on site for 8:00 with the day's paperwork only taking them until 8:15am. They began tearing out the plywood walls, working through 11:00am. After that, the area was cleaned and prepared for the floor membrane over the next couple of hours. The DecTec was installed between 1:30 and 6:45, with one of the team members departing for the evening around 4:00pm. The site was cleaned up between 6:30 and 6:45pm, with garbage disposed of and the materials and tools packed away.     Roof Report: December 11, 2013 The team started their day for 8:00 once again, filling out the pertinent paperwork and bringing all tools and materials into the work area by 8:30am. They began preparing the walls for the Tyvek wrapping by removing all of the preexisting staples and nails from the structure and surface. Half an hour later, they began installing the Tyvek wrapping, taped up the joints, and affixed peel-and-stick membrane to the area. The membrane was all installed by 5:00pm, so the team spent the next hour and a bit cleaning up the site, removing the materials and tools from the work area. Come 6:30pm, they were prepared to depart for the evening, and the jobsite complete.   CODE: 649 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
