What permits, inspections, and HOA approvals does Sammamish require for a new roof?
The City of Sammamish requires building permits for roof replacements, with inspections typically required before and after the work. Verify the permit application names you as the property owner — when a Sammamish contractor pulls a permit in their own name, you can't independently track inspections or appeal failures.

What should a roofing quote in Sammamish include?
A complete quote in Sammamish should include tear-off, underlayment, flashing, drip edge, starter strip, ridge cap, decking inspection, disposal/cleanup, and the permit. Mixed-climate quotes should still call out ice and water shield in the lowest-temperature months and ridge ventilation for summer attic heat. Any Sammamish bid that omits these items deserves a follow-up question; the gaps are how a "low" quote becomes the expensive one by the end.
