How to tell if a storm damaged your roof, without going up there

The short answer: you probably cannot tell from the ground, and that is exactly why storm damage in Southwest Florida so often goes unnoticed until it turns into a ceiling stain months later.

But there is a lot you can check without a ladder, and knowing what to look for will tell you whether it is worth getting somebody up there.

Why a damaged roof looks fine from the driveway

The most common form of wind damage on an asphalt shingle roof is a broken seal. Shingles are held down partly by nails and partly by a strip of factory adhesive that bonds each course to the one below it. Wind gets under the leading edge of a tab, flexes it up, and breaks that bond.

Then the tab lays back down. From the ground it is indistinguishable from an undamaged roof. It is no longer sealed, so the next driving rain runs underneath it rather than over it, and the water goes onto the underlayment and eventually into the deck.

On tile the equivalent problem is a hairline crack or a tile that has slipped a fraction out of alignment. Neither is visible from sixty feet away at ground level.

What you can check from the ground

1. Walk the perimeter and look down, not up

Granules. Asphalt shingles shed a mineral granule surface as they age, and they shed a lot of it very suddenly after hail or hard wind. Check the base of downspouts, the splash blocks, and the ground immediately below the gutter line. A sudden accumulation of coarse black or grey grit is one of the few reliable ground-level signals of roof damage.

2. Look at the ridge line against the sky

Stand back far enough to see the ridge as a silhouette. It should be dead straight. Any dip, wave or gap where a ridge cap has lifted or gone missing is worth a closer look, because ridges and hips take the highest wind pressure on the roof and are usually the first thing to fail.

3. Check the drip edge and the gutter line

Drip edge is the metal strip along the roof edge. If it has peeled away, buckled, or is visibly no longer flush, water is getting behind the roofing system rather than running on top of it. That is a worse failure than a hole in the middle of a slope.

4. Look for debris in the gutters that is not leaves

Pieces of shingle, chunks of tile, fragments of mortar from a hip or ridge. Any of those in the gutter came off your roof.

5. Look at the soffit and fascia

Wind-driven water that has got behind the edge often shows up here first: staining, softness, or a section of soffit panel that has come loose.

6. Go into the attic with a torch

This is the most useful thing on the list and the one most people skip. In daylight, with the lights off, look for pinpricks of daylight through the deck. Then look for dark staining on the underside of the sheathing, wet or compressed insulation, and rusted nail shanks. Staining shows you where water has been even when it is currently dry.

7. Look at your ceilings and the tops of your walls

Not just for obvious stains. Look for faint discolouration, a change in the paint sheen, or hairline cracking that was not there before. Also check inside closets and in the corners of rooms on the top floor, which is where slow leaks tend to surface first.

What none of this tells you

All seven of those checks can come back clean on a roof that has broken seals across an entire windward slope. Ground-level inspection is good at catching gross damage and useless at catching the most common kind.

That is the honest limitation, and it is why we do not charge for the inspection: the only way to answer the question properly is for somebody to get up there.

Why the timing matters

Two reasons.

The first is physical. A broken seal that lets water onto underlayment for one wet season is a repair. The same failure left for three seasons can involve underlayment across a whole slope and possibly the deck beneath it.

The second is procedural. Under Florida law, notice of an initial or reopened property insurance claim must be given to the insurer within one year of the date of loss, and a supplemental claim within 18 months of the date of loss. If a storm went through in September and you find the damage the following November, you may still be inside the window. If you find it two years later, you are not, regardless of how clearly the storm caused it.

What to do next

If any of the ground-level checks came back positive, get it looked at. If they all came back clean and a storm with real wind behind it went over your house, get it looked at anyway, because clean ground-level checks are not evidence of an undamaged roof.

Either way, the inspection is free, it takes under ninety minutes, and you get a written report with photographs whether or not anything is wrong. If the roof is sound, that document is worth having on file at renewal time.
