A new torch-on roof on an industrial building.
A $175,000 commercial flat roof replacement in Calgary. Our own crew put a new two-ply torch-on roof on both sections of the building, with every vent stack flashed into the membrane.
- Industrial building, Calgary
- $175,000 project
- Two-ply torch-on
- Every vent stack flashed
What the job needed
The roof has rows of vent stacks across it, and every one of them is a place a flat roof can leak. Each one had to be flashed into the new membrane.
How we did it
-
New board, fastened down
New board went down across the roof and was fastened to the deck.
-
Base sheet
A torch-on base sheet over the whole roof, run up and around every vent stack.
-
Cap sheet
The granulated cap sheet torched over the base, lap by lap.
-
Both sections finished
Both roof sections finished the same way, with the rooftop units sealed in.
