Spring and fall from the ground
Use binoculars from the yard. Look for missing tabs, exposed nails, sagging ridges, and shingle edges that look wavy. From the attic, look for daylight, rusted nails, and dark staining on the underside of the deck.
- Granules piled in downspouts after rain
- Shingles curling at the edges or bald spots
- Drip edge pulling away from the fascia
Gutters, valleys, and flashing
Clogged gutters force water under shingles. Valleys and step flashing at walls and chimneys fail more often than the field of the roof. After leaf drop, clear screens and check that downspouts discharge several feet from the foundation.
- Clean gutters at least twice a year, more under trees
- Look for rusted or pulled chimney counterflashing
- Reseal or replace cracked pipe boots
What not to do yourself
Walking a steep or wet roof is a common way homeowners get hurt and void warranties. Limit DIY to ground-level photos, attic checks, and gutter work from a stable ladder with a spotter.
- Do not pressure-wash asphalt shingles
- Do not use cheap roofing tar as a long-term leak fix
- Hire a licensed roofer after hail, high wind, or a ceiling stain
