2. Roof Deterioration and Ceiling Water Intrusion

The roof serves as the primary defense barrier against rain, snow, and UV radiation. Once shingles fail, water infiltration begins degrading roof decking, structural trusses, and interior drywall.

• Shingle Degradation and Granule Loss: Inspected from ground level, missing, curled, buckled, or blistering asphalt shingles indicate severe weathering. Granules that collect in gutter troughs and downspouts signify that shingles have lost their protective coating, exposing underlying organic mats to water penetration.

• Ceiling Stains and Drywall Sagging: Water staining on top-floor ceilings or upper wall corners—typically appearing as yellow, brown, or rust-colored rings—indicates an active roof leak or flashing failure around chimneys and roof vents. Ignoring minor ceiling discoloration eventually saturates attic insulation, encourages black mold growth, and causes ceiling drywall to sag and collapse.

• Damaged Soffits, Fascia, and Flashing: Metal flashing installed around valleys, chimneys, and dormers keeps water flowing away from roof intersections. Corroded, bent, or missing flashing allows water to seep directly into wall cavities. Rotted wooden soffits and fascia boards create points of entry for pest infestations.
