Nor'easter Shingle Blow-Off: What to Do in the First Hour

The first hour

1. 1

   Look, do not climb

   Walk the perimeter from the ground with binoculars or a phone camera zoomed in. Wet or wind-damaged roofs are genuinely dangerous and you gain nothing by being up there.

2. 2

   Photograph from every side

   Wide shots of each elevation showing the whole roof plane, then zoomed shots of the damage. Photograph the shingles that landed in your yard where they landed, before you pick them up.

3. 3

   Check the interior and attic

   Look for fresh stains and, in the attic, for daylight or damp sheathing. Underlayment is water-resistant, not waterproof — if the shingles are gone, water is getting in somewhere.

4. 4

   Get exposed areas covered

   Bare deck or exposed underlayment will not survive the next rain. That needs a proper tarp the same day.

5. 5

   Note the date and the storm

   Write down the date and roughly when it happened. Claims tied to a specific documented weather event are dramatically easier to get approved than vague reports.

The damage nobody looks for: broken seal strips

Every asphalt shingle has an adhesive strip that bonds it to the course below. That bond is what makes a roof a continuous surface rather than a stack of loose tiles.

Wind does not usually rip shingles off. It gets under the leading edge, breaks the seal, folds the shingle back, and lays it down again when the gust passes. From the ground the roof looks completely untouched. In reality that shingle is unsealed and creased along the fold line, and the fiberglass mat inside is fractured.

The next storm will take it, along with the ones above it that it was helping hold down. And crucially: the damage was caused by the storm that unsealed it, not the one that finally removed it. That distinction is worth real money on a claim.

Finding it requires someone lifting tabs by hand across each slope. It is the most commonly skipped step in this market and it is on every inspection we do — see wind and hail damage repair.

Where wind damage concentrates

• Rake edges — the sloped edge at the gable end, where wind gets its first purchase. Missing starter strip here is the most common installation defect we find
• Ridge and hip caps — the most exposed shingles on the roof and usually the first to go
• The windward slope — damage follows the storm's direction, so one elevation is typically far worse than the others
• Around raised edges — anywhere a previous repair, a vent or a skylight creates a lip for wind to catch
• Valleys — where two slopes meet, wind accelerates and any loose material lifts

What your insurer will want

Wind claims are usually straightforward when documented properly and frustrating when they are not.

You want: dated photographs of each elevation, photographs of the shingles that came off, a professional inspection report identifying damage per slope, documentation of seal failure where it exists, and the date of the specific weather event.

You also want to check one line on your declarations page before filing: many Pennsylvania policies carry a separate wind and hail deductible, frequently calculated as a percentage of dwelling coverage rather than a flat amount. On a $350,000 home, a 1% wind deductible is $3,500, and that changes the arithmetic on a small claim considerably.

Repair or replace after a blow-off

It depends on how much of the roof is affected and whether your shingle can still be matched.

Isolated damage on one slope with a current-production shingle is a repair. Damage across multiple elevations, or a discontinued shingle where a repair would leave a visibly mismatched patch on a front elevation, is a legitimate argument for slope or full replacement in a claim.

What a repair must include: replacement rather than re-sealing of creased shingles, hand-sealing in cold weather so the new material bonds immediately, and the correct nailing pattern for the shingle's wind rating — which on most high-wind laminates is six nails, not four.
