Inspect Roof Flashing
Why It Matters
Flashing failures are the number one source of roof leaks. Most roof leaks start at flashing points, not from shingle failure.

Perform the inspect roof flashing
Check flashing around chimneys, vents, skylights, and wall junctions for gaps, rust, or lifting. Safety note: Inspect from ground level when possible.

Community Tips
Flashing failures are the leading cause of interior water damage within 5-10 years of roof installation, often going undetected until drywall staining appears inside walls. Missing or lifted flashing around chimneys, vents, and skylights requires immediate caulking with a marine-grade sealant like Sikaflex 291 ($12-18) to prevent costly structural rot.
Binoculars eliminate the need for roof access on single-story homes and reduce fall risk significantly -- 10x magnification allows clear inspection of flashing overlaps, separation points, and sealant deterioration from ground level without requiring a ladder or scaffolding rental ($50-150/day).
Replacing compromised roof flashing runs $300-800 per penetration (chimney, vent stack, or skylight) when caught early, but water intrusion damage can escalate repair costs to $2,000-5,000+ for interior wall reconstruction and mold remediation if left unaddressed for more than one season. ---
