Find the cause before choosing the repair
Ask the roofer to identify the entry point, the affected roof area, and any interior or deck damage they can assess. Request photographs and a written repair scope. Sealing the visible stain location is not a substitute for finding where water entered.
Compare repair and replacement recommendations
Ask what condition the surrounding roof is in and whether the proposed repair can tie into it. If a contractor recommends full replacement, ask what evidence makes a limited repair unsuitable. Compare the warranty and exclusions for each option.
Account for the roof type and location
For a membrane roof in the Pearl District, include seams, drains, parapets, and penetrations in the assessment. On a St. Johns home, ask whether the bid includes adjoining flashing or only the damaged covering. Use the roof assembly and inspection findings to define the work.
Document storm damage and approvals
If damage follows a storm, organize photos, dates, and the contractor assessment before discussing a claim. Our storm damage guide covers that process. Confirm the permit requirements for the actual repair scope rather than using an assumed percentage-of-roof rule.
Choose a contractor for the scope
Before signing, check the Oregon CCB license and compare the written scope, payment schedule, and warranty. You can request a roofing referral through this site; confirm the contractor’s credentials and availability before hiring.
