Ignoring a roof leak leads to progressive, compounding property damage that rapidly escalates in cost. Trapped moisture causes attic insulation to clump and lose thermal efficiency, rots wooden rafters and plywood decking, promotes hazardous mold and mildew growth that affects indoor air quality, and eventually rots interior ceiling drywall, causing structural collapse. Timely repair prevents minor flashing or shingle failures from turning into catastrophic structural home disasters.
