Roof replacement in Washington

Replace when repair no longer fits

When leaks keep returning or wear is spread across the roof, a replacement assessment can show whether a full project is the better fit. A site review should separate visible conditions from details hidden beneath the covering. A clear proposal explains what was observed, what still needs to be checked, and what could change after removal.

A roof measurement helps estimate materials and plan access; a condition assessment reviews the roof assembly. Share its approximate age, leak history, past repairs, and any interior staining. Keep safe ground-level photos ready for follow-up, and stay off the roof when taking them. Use the repair-or-replacement guide to prepare for that review.

Price the full roof system

A complete proposal names removal or overlay assumptions, the covering, underlayment, flashing, edges, ventilation work, disposal, and cleanup. It also describes property protection and details at chimneys, skylights, walls, valleys, and roof edges.

Deck condition can change the scope after removal. The written plan should say when the deck will be checked, how added repairs will be measured, and how approval is recorded before that work begins. Compare bids using the same roof area and removal assumptions, then check product names, exclusions, payment points, and completion documents. The replacement budget guide explains what a planning range leaves open.

• Existing layers and removal or overlay assumption.
• Named products, flashing details, and ventilation scope.
• Deck inspection and written change approval process.
• Protection, disposal, cleanup, and completion documents.

Choose materials by system details

Material choice shapes the details in a replacement plan. For asphalt shingles, standing-seam metal, tile, or green roofing, name the exact assembly, related transitions, supporting work, and any specialist review.

A material label alone does not explain what will be installed. Compare complete system details, including how each roof section meets walls, openings, edges, and existing work. See the cedar replacement scope or compare metal with shingles.

For a roof replacement proposal, share the city, approximate roof age, leak or storm history, current covering if known, and whether you are comparing repair with replacement. Have safe ground-level photos ready for follow-up.

Before signing, check the contractor record through Washington L&I and compare written scope, terms, and exclusions. Confirm how hidden conditions will be documented and how added work is approved.
