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.

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.

Photo Gallery: Edmonton Rooftop Deck, September 2010

This report serves to show the before-and-after difference that a rooftop patio reconstruction can make. There are no in-progress reports to cover; just a photo gallery to highlight the expertise that GRS can bring to your household upgrades.  
001
After removing the original roof membrane and step flashing from the perimeter of the patio, we applied new roof boards to the surface.
002
This custom fit section is where we would later install a drain. We ensured that the piping was in full repair and that the surrounding roof surface had no deficiencies.
004
Once the boards were installed, we began laying EPDM over the roof.
 
005
EPDM was secured against the wall connections using termination bars around the perimeter. This contributed to the watertightness we were aiming for.
006
Completed drain installation.
008
010
Post-installation photograph, with terminal bars completely installed around the perimeter. All that remained was liquid rubber coatings over the seams.
009
Detailing at the door. The EPDM is folded over itself underneath the termination bar.
