Flat & Low-Slope Roofing in Whatcom County
Torch-down & single-ply for additions, decks, and modern homes.
Flat and low-slope roofs — over additions, garages, decks, and modern Whatcom County homes — need a very different system than a pitched roof. Get it wrong and water pools, then finds every seam.
We install torch-down (modified bitumen), heat-welded TPO/PVC single-ply, and EPDM rubber membranes. We shape the drainage so water actually leaves the roof, and we flash every penetration and wall transition right. These systems survive standing water and our heavy winter rain.
The local difference
Low-slope roofs punish sloppy seams in our wet winters. We weld and detail them to shed water, not trap it.
