Bellingham Roofing Contractor

“There's thick moss creeping up the north-facing slope of my roof under the firs over by Silver Beach. Is it too late to treat it, or do I need to replace the shingles?”

Moss itself rarely means instant replacement — the question is what's under it. We'll do a low-pressure clean and treatment (never a pressure washer, which strips granules), check the shingles and deck for soft spots, and install copper or zinc ridge strips so it doesn't come back. Shaded, tree-lined Bellingham lots grow it fast, so if we find rot underneath we'll show you exactly where.

“I've got a water stain on my bedroom ceiling but the roof above it looks fine. Where's the leak actually coming from?”

Water almost never enters directly above the stain — it travels along the deck or a rafter before it drips. Common culprits are flashing, a cracked plumbing boot, or a valley uphill of the stain. We track the actual entry point, fix that, and document it with photos so you're not paying to chase the wrong spot.

“My skylights leak every winter no matter how much sealant I glob on. Can you actually fix that for good?”

Sealant is a band-aid — skylights leak because the flashing kit is wrong, old, or was never step-flashed into the roof properly. The real fix is to re-flash the skylight into the roofing system with the correct kit and, if the units themselves are shot, replace them. Done right, it stops leaking without a tube of caulk every fall.
