A nor'easter doesn't always announce its damage. Sometimes a few shingles are lying in the yard. Other times the roof looks fine from the driveway and the problem only shows up weeks later as a ceiling stain.
If you're on Long Island, you've been through enough of these storms to know they bring strong wind and hard, sideways rain for hours at a time. Here's how that affects a roof, what to look for, and what to do first.
How a nor'easter stresses a roof
Two things do most of the work: wind and wind-driven rain.
Wind lifts and loosens
Sustained wind puts constant pressure on shingles. Shingles that are already worn, poorly sealed, or nailed improperly can lift, crease, or tear away. Edges, corners, and ridges take the most stress.
Rain gets pushed where it doesn't normally go
In a regular rain, water runs down the roof. In a nor'easter it gets blown sideways and upward, toward flashing, vents, chimneys, and the edges of shingles. Small weaknesses that never leaked before can start letting water in.
Debris hits the roof
Branches and other debris can crack shingles or puncture the roof surface. Gutters full of leaves can back up, which sends water where it shouldn't go.
Exposure varies. Roofs closer to open water or with fewer trees around them may take more wind. Whether you're in Huntington, Smithtown, Commack, Babylon, Bay Shore, or Islip, the condition and installation quality of your roof matters more than the town.
Signs your roof may have storm damage
Start with what you can see from the ground.
- Missing shingles: Look in the yard, driveway, and gutters
- Lifted, creased, or curled shingles: These may not have blown off but can still fail
- Exposed or bent flashing: Especially around chimneys, vents, and roof valleys
- Granules in gutters: A sign of surface wear that storms can speed up
- Debris on the roof or gutters: Branches, leaves, or anything that hit the roof
- Sagging or uneven areas: This can point to a water or structural issue
Then check inside:
- Water stains on ceilings or upper walls
- Damp or darkened insulation in the attic
- Daylight coming through roof boards
- A musty smell after heavy rain
Storm leaks don't always show up right away. Check again after the next rainfall.
What to do first
1. Stay safe. Do not climb on the roof after a storm. Wet, damaged roofs are dangerous. Use binoculars or your phone's zoom from the ground.
2. Take photos and video. Capture anything you see on the roof, in the yard, and inside the house, with date and time if you can. This helps if you file an insurance claim.
3. Prevent further damage if you can do it safely. If water is coming in, move belongings and put a bucket under the drip. A roofer can tarp the damaged area.
4. Get the roof inspected. Damage you can't see from the ground is common. A roofer who gets up there can tell you what's repairable and what isn't.
5. Contact your insurance carrier. Many homeowners policies cover some storm damage, but coverage depends on your specific policy. Your carrier can tell you what applies to you.
Repair or replace after a storm?
It depends on how far the damage goes. Limited damage, such as a few missing shingles or a torn section of flashing, is often a roof repair. Widespread damage or damage to the decking underneath may call for a shingle roof replacement or a full reroof. For the signs that separate the two, see our guide on whether to repair or replace a roof.
The inspection is what settles it. See our storm damage repair page for how we handle these jobs.
Being ready before the next one
You can't stop a nor'easter, but you can reduce the risk:
- Have the roof inspected before storm season, especially if it's been a while
- Fix known problems like loose flashing, cracked pipe boots, or lifted shingles
- Trim branches that hang over the roof
- Keep gutters clear so water drains away from the roofline
A free roof inspection before the season can turn up small problems while they're still small. For a full fall checklist, see how to get your roof ready for winter.
