Roof Canopy Reconstruction Edmonton, Alberta. Flat Roof. Tar and Gravel. Multi-Family.
Below is a continuation report from our Tar and Gravel Roof Repair blog entry on May 31, 2015. The continuation below describes the reconstruction of the front entry door roof canopy of the condo that the crew was working on.
April 30, 2015: Roofing crew attends to location for reconstruction of the entry canopy.
Location: 10315 113 Street NW Edmonton, Alberta.
Type of Property: Multi Family.
We arrived at 7:30 am and filled out safety documentation and conducted our tool box safety site meeting. We had 2 different scopes of work to do to finish work on this building.
The first scope consists of re-installing the metal flashing on perimeter the perimeter of the tar and gravel flat roof. The scope of work consists of overlapping the existing metal flashing that was on the building and fastening the end of each piece of flashing.
The second scope was the reconstruction of the entry door roof canopy and installation of the waterproofing flat roof membrane material.
The old tar and gravel membrane had been removed prior. Today we started by ripping off the old rotten plywood and 2" x 6" 's. We then framed in some new 2"x 6" 's to replace the old rotten joists pieces. We then used 2" x 4" 's to make a lever and push up on the front left corner to bring it up level with the rest of canopy. Raised it up roughly 3 inches.
When the other guys finished up installing metal on the flat roof they started helping us with the remaining work on the front entry. At this point the canopy was up to level and had new trusses installed. We installed new 1/2" plywood sheathing on top of the trusses and screwed it all down for a secure substrate.
We then fabricated a new cant flashing and installed all new cant around the left hand side and left front of the canopy.
The next step was to install the FR board (which is a roof board with the base sheet SBS modified attached to it at the factory) on top of the plywood and screwed it down.
We then had to stop due to rain and the site was set-off for completion.
The crew will finish off the installation of the 2 ply SBS modified torch-on roof membrane tomorrow (including base striping, SBS cap sheet install and putting the metal flashing back on).
There are roughly 5 hours of work left to complete.
2 - 4' x 8' sheets of plywood.
3 - 2" × 6" 8 ' pieces.
2 - sheets of FR board (SBS modified base membrane with roof board attached).
4 - 2"×4" 8' pieces for the cant flashing.
