Homeowners unable to identify and fix missing roof flashing before water damage occurs

Homeowners lack the knowledge to spot missing or damaged flashing on rooflines and siding, leading to costly water infiltration, mold, and structural damage that could have been prevented with early intervention. DIY homeowners turn to forums for help because they can't afford contractor quotes ($500-2000+) and don't know if the problem is urgent or how to fix it themselves. Current solutions (forum posts, generic YouTube videos) provide inconsistent advice and don't give homeowners confidence in their diagnosis or repair approach.
