Roof Inspection From the Ground: What Binoculars Can Tell You

A roof rarely fails without warning. Shingles curl, granules wash into gutters, and flashing lifts long before a leak shows up on the ceiling. A twice-yearly ground inspection with a pair of binoculars catches most of this early, and it costs nothing but twenty minutes.

What to look for from the ground

• Shingles that look darker, shinier, or patchy in one area — a sign of granule loss and thinning.
• Curling or cupping edges on asphalt shingles, usually starting on the side that gets the most sun.
• Missing or slipped shingles, especially after high wind.
• Sagging ridgelines or valleys, which point to structural or decking problems rather than surface wear.
• Rust streaks or gaps around flashing at chimneys, vents, and skylights.
• Moss or dark algae streaks, which hold moisture against the shingle surface and shorten its life.

Check the gutters too

Granules in the gutter are normal in small amounts on a new roof and a red flag in large amounts on an older one — asphalt shingles shed their protective granule coating as they age, and heavy loss usually means the roof is within a few years of needing replacement rather than repair.

Age is still the best predictor

After a storm, check sooner

Hail and high wind justify an off-schedule inspection. Hail bruising on asphalt shingles often looks like small dark dimples rather than obvious holes, and it can take months to turn into an active leak, which is exactly why insurers usually give a generous window to file storm-damage claims.

Interior clues worth checking at the same time

• Attic: check for daylight through the roof deck, damp insulation, or dark staining on rafters.
• Ceiling: look for faint brown rings, which mean water has already tracked through at some point.
• Exterior walls below roof valleys: staining here often means the valley flashing has failed.
