Water Stains, Drips, and Dark Patches Indoors
A pale ring that expands after each storm means active water intrusion, not a cosmetic blemish. Photograph the stain, note the weather pattern, and act quickly before insulation saturates and drywall crumbles.
Sagging Lines and Soft Spots: Structural Red Flags
Dips along ridges or between rafters
Stand back across the street and study the silhouette at sunset. Subtle waves along the ridge or between rafters indicate structural fatigue. Acting early can prevent cascading failures during heavy snow or rain.
Spongy sheathing underfoot
If a professional carefully walking the roof feels bounce or give, moisture may have degraded the plywood beneath. Soft sheathing spreads quickly, distorting shingles and nails. Request photos, a moisture reading, and a clear repair plan.
Persistent ice dams that linger
Ice dams reveal heat loss and uneven roof temperatures that melt and refreeze snow. Repeated ice ridges warp edges and saturate underlayment. Improve insulation, ventilation, and sealing, and share your winter observations with our community.
Flashing, Chimneys, and Skylights: Small Gaps, Big Leaks
Dried, split sealant at metal transitions invites capillary action that pulls water inside. Look for gaps you can slide a credit card into. Resealing is urgent; delaying risks hidden rot along framing.
Flashing, Chimneys, and Skylights: Small Gaps, Big Leaks
Rust around vent collars signals corrosion and microscopic openings. In wind-driven rain, those pinholes behave like open faucets. Replace failing components, and consider upgraded flashings designed for your climate and roof pitch.
Moss, Algae, and Mold: Moisture’s Green Warning
Thick moss lifting shingles
Moss acts like a sponge, prying up shingle edges and holding water against the mat. The bond fails, granules shed, and leaks follow. Remove growth gently and address the underlying shade and drainage problems.
Black streaks and what they mean
Streaks often mean algae feeding on limestone filler. Though mostly aesthetic, they reveal persistent dampness. Improve sunlight exposure where possible and consider algae-resistant shingles if your neighborhood struggles with recurring stain patterns.
Ventilation numbers that matter
Poor airflow breeds moisture and growth. Aim for balanced intake and exhaust ventilation, typically about one square foot of net free area per 300 square feet with a vapor barrier. Share your attic temperatures and results.
Daylight in the Attic and Rising Energy Bills
01
Daylight visible around nails or between boards points to gaps where rain and pests also enter. Mark the spots, check after rain, and document photos to prioritize targeted repairs before widespread damage occurs.
02
When your system runs more often and rooms feel drafty, suspect attic air leaks and wet insulation. Moisture reduces R-value, driving costs up. Track your usage and ask questions in the comments for tailored advice.
03
A simple digital hygrometer in the attic can warn of hidden roof issues. Sustained high humidity encourages condensation, mold, and fastener corrosion. Post your readings and subscribe for our monthly maintenance checklist.
