Record when it appears

Photograph the stain and note recent rain, snowmelt, wind and changes in size. Check only places you can reach safely; do not climb onto a roof.

More than one path is possible

Flashing, crown, masonry, cap, condensation or nearby roof details may be considered. Ask the contractor to show what evidence supports the proposed repair.

Compare a written scope

Ask what components are included, what is excluded, whether repair and water-repellent treatment are separate, and what follow-up or warranty is offered.

Find a local company and confirm scope

Company profiles are directory records, not a diagnosis or endorsement. Confirm current service area, qualifications, insurance, availability and written scope directly with the provider.
