Most roof failures are visible months before they leak. This is the same checklist our inspectors use on the ground before they ever set a ladder. Twenty minutes once a year saves five-figure repair bills.
From the ground (binoculars + phone camera)
- Missing, lifted, or curling shingles — especially along ridges and valleys.
- Dark streaks (algae) or moss — usually cosmetic but indicates moisture retention.
- Sagging rooflines — possible decking rot or framing issue.
- Damaged or rust-stained flashing around chimneys, skylights, and vent pipes.
- Granules in gutters or at downspout outlets — sign of shingle aging or hail.
- Gutter sag, separations, or rust spots.
Inside the attic
- Daylight visible through the roof deck — a major red flag.
- Dark water staining on rafters or decking.
- Compressed, moldy, or wet insulation.
- Improperly vented bathroom or kitchen exhausts terminating in the attic.
- Inadequate ventilation per ARMA (opens in new tab) (you want intake at the eaves AND exhaust at the ridge).
What needs a pro
Walking the roof for hail, evaluating flashing penetrations, measuring deck deflection, and certifying damage for insurance all need a HAAG-certified inspector (opens in new tab). Our free inspections include a written report you can hand to an adjuster or buyer.
How often to inspect
- Once per year (spring is ideal in Alabama, after pollen season).
- After any hailstorm 1"+ — check NWS Birmingham (opens in new tab) or NWS Huntsville (opens in new tab) for storm size.
- Before listing your home for sale.
- When a roof passes the 12-year mark — that's when subtle issues start to compound.
