Bellevue Roof Installation on Additions and New Decks
A new Bellevue garage or family-room bump-out has to tie into a house that already leaked at that wall once. We flash the intersection, ice-barrier the eave, and match the field if the line still exists.

Tie-In, Not a Patch.
How We Install a Roof on a Bellevue Addition
The old wall is the leak line: We open the step flashing and rebuild it. Caulk on the siding is how the addition stains in year two.
Same system as the house when we can: Architectural asphalt to match, or a honest note if the blend is dead.
Permit with the addition: If the addition already has a Bellevue permit, we coordinate the roof line so Building & Code is not seeing two stories.


New Deck Rules
What Has to Be Under a New Bellevue Roof
Ice-and-water at the new eave: A low addition ices first. We do not skip the membrane to save a square.
Ventilation if you closed the old soffit: Sealing the original intake to build a room is how the old field cooks. We will point at it.
Not a rolled-roofing house: Low-slope porches may need a membrane, not a hardware-store roll. We write that system.
Frequently Asked Questions
Yes. The job is the tie-in and the drainage, not just the new squares.
If the shingle is still made. If not, we show the closest blend on the house before we order.
If the addition is permitted, the roof is part of that path. A stand-alone re-roof of the house is its own Bellevue permit.
