How do I know whether my roof needs repair or replacement?
Localized failures on an otherwise serviceable roof may be repairable. Widespread deterioration, recurring leaks and significant substrate problems make replacement more likely. A site evaluation is the best way to compare the two. See roof repair and roof replacement.
Can a ceiling stain be far from the roof leak?
Yes. Water can travel along decking, framing, underlayment or insulation before becoming visible indoors.
Do all roof replacements in Seattle require a permit?
No universal answer applies to every building. Seattle distinguishes detached one- and two-family work from many commercial and multifamily reroof projects. Check current SDCI requirements for the exact scope. See roofing permits.
What roofing material is best for Seattle?
There is no single best material. Roof slope, drainage, building design, budget, maintenance, substrate and owner priorities determine whether asphalt shingles, metal, TPO, PVC, EPDM, modified bitumen, cedar or another system is appropriate.
Do flat roofs need slope?
Low-slope roofs still need a drainage strategy. “Flat” does not mean the roof should be designed to hold water indefinitely. See flat roofing.
Can you repair TPO, PVC or EPDM?
Often yes, when the surrounding membrane is serviceable and the system is correctly identified so compatible repair materials and methods can be used.
What happens if damaged roof decking is found during replacement?
The contract should explain how decking is evaluated, documented and priced if concealed damage is discovered during tear-off.
Should I replace my roof before installing solar?
The remaining roof condition should be evaluated before placing long-lived equipment over it. Coordinating roof and solar timing can avoid unnecessary future removal and reinstallation.
How should I verify a Washington roofing contractor?
Use the Washington Department of Labor & Industries contractor Verify tool and compare the legal business information with the contract. See contractor verification.
Do you work on commercial and multifamily roofs?
Yes, this site is structured for residential, commercial and multifamily roofing. Replace this sentence if A1 Roofing later narrows its actual operating scope.
What areas do you serve?
Seattle and surrounding communities including the Eastside, North and South King County, and the Seattle-to-Everett corridor. See Service Areas for the current list.
