The Ultimate Roof Inspection Checklist: Don’t Miss These Critical Areas!

The shingle field, every flashing point, the eaves and gutter line, the decking, the attic underneath, and the soft metal at ground level. The attic matters as much as the roof — ventilation failures and early decking damage show there first.

Annually, plus after any significant hail or high-wind event. Annual inspection catches flashing failures and lifted shingles while they are still small repairs. Post-storm inspection matters even when nothing looks wrong, because hail bruising is invisible from the ground.

You can do the ground-level half safely: check gutters and downspouts for dents and granules, look at the roof line for sag, and look for lifted shingles with binoculars. Leave anything requiring a ladder or roof access to someone with fall protection.

Skipping any one of these is how damage gets missed:

• The shingle field — granule loss, curling, cupping, cracking, and the circular bruising that hail leaves.
• Flashing at chimneys, valleys, vents, skylights and roof-to-wall intersections. Most leaks begin here, not in the open field.
• The eaves and gutter line — the damage ice dams leave, and whether the gutters actually drain.
• The decking, checked underfoot for soft or spongy areas and visually for sag along the roof line.
• The attic — daylight through the deck, moisture staining, frost on the underside in winter, and whether soffit vents are clear.
• Ground-level soft metal — gutters, downspouts, window wraps and the air conditioner, where hail shows most visibly.

Almost everything that shortens a Minnesota roof's life is visible from underneath before it is visible from above. Daylight through the deck means water is already getting in. Frost or dampness on the underside of the sheathing means warm household air is reaching the deck, which is the mechanism behind both premature shingle ageing and ice dams.

Blocked soffit vents — usually insulation pushed into the eaves — are one of the most common findings and one of the cheapest to fix. An inspection that never opens the attic hatch cannot report any of it.

Ground-level checks are genuinely useful. These are the ways they go wrong:

• Getting on the roof. It is the single most dangerous thing a homeowner does around a house, and worse on wet or hail-struck shingles.
• Judging hail damage from the ground. Bruising does not read from below or in a photograph.
• Checking only after a leak. By then the decking and insulation have usually been wet for a while.
• Ignoring the attic, where the earliest evidence actually is.
• Assuming a young roof is a healthy roof. Ventilation faults and hail affect new roofs too.
