A nor’easter blankets central New Jersey with a foot of wet snow. You wake up to buried shingles and icicles hanging over your front steps. Do you wait for the snow to melt or grab the ladder?
Keep that ladder in the garage. You can spot most signs of roof damage from snow from your yard or a second-floor window. Inside, check the ceilings above your bedroom windows for new stains, too.
For a winter roof inspection, I start at the roofline, then look inside if it’s safe. I’ll show you what to check and which calls can wait until the snow melts.
What Should You Check on Your Roof After Heavy Snow?
After heavy snow in New Jersey, check your roof from the yard, a window or the attic, never from a ladder. Look for a sagging roofline, ice dams or large icicles, gutters pulling away, new ceiling stains and damp insulation. If you hear cracking or see a ceiling sag, get out and call for help.
The Shore typically gets less snow than northwestern New Jersey, but a nor’easter can still bring heavy, wet snow to Monmouth and Ocean counties. When meltwater refreezes at the edge of your roof, it can form ice dams. A sound roof is built to carry a lot of snow, so look for changes.
Signs of Roof Damage From Snow You Can Spot From the Ground
Use binoculars or the zoom on your phone from a window, driveway, or yard. As you inspect for snow damage to the roof, stay out from under the eaves, where snow and ice can slide off.
- Roofline. From across the street, look along the peak and the eaves for a new dip or sag. A summer photo of the house makes one easy to spot. If you find one, go straight to the emergency signs below.
- Eaves. A thick ridge of ice along the roof edge is an ice dam. It traps meltwater, which can back up under the shingles. Large icicles, or water dripping from behind the gutter, are signs that may be happening.
- Gutters and downspouts. Are the gutters bending or pulling away from the fascia, the board they’re fastened to? Check whether ice is blocking the downspout outlet.
- How the snow is melting. Are the eaves still covered in snow, while the roof is exposed higher up? That usually means attic heat is melting the snow from below, and the runoff refreezes at the cold edge.
- Debris in your yard. Look on the snow and around the house for shingle pieces, gritty granules or bits of drip edge, the metal trim along the roof edge. Note any fallen branches, and any limbs still hanging over the house.
Check Inside Next: Your Attic and Top-Floor Ceilings
If you see a new sag or hear cracking, leave the house. Check the attic only if you can reach the hatch safely.
- Attic. From the hatch, use a flashlight. Step only on the joists if you can do so safely. Look for active drips; damp, matted or discolored insulation; bowed rafters; and daylight showing through. Check the roof deck, the boards or panels under the shingles, for sagging or damp spots. Frost or water beads on the deck or nail tips are condensation, usually a sign of poor attic ventilation.
- Top-floor ceilings. Look for new stains, bubbling paint or fresh drywall cracks, especially along exterior walls under the eaves, where ice dam leaks tend to show up first.
If water is coming in, see what to do about an active leak.
When Snow on the Roof Becomes an Emergency
These signs from the FEMA Snow Load Safety Guide may mean the snow load on your roof is straining the framing.
- Popping, cracking or creaking from the roof or attic.
- A sagging or bulging ceiling, or bowed rafters or roof decking.
- New cracks in walls, plaster or masonry.
- Doors or windows that suddenly stick or won’t open or close.
- A severe leak, with water pouring in rather than dripping.
Get everyone out of the house and ask for outside help if you see any of these symptoms. Call 911 if you think a roof collapse is imminent.
Have a structural engineer inspect the framing. A roofer can check the shingles and decking when safe.
If water is actively dripping and there are no other warning signs, call a roofer now. For a large ice dam and a dry interior, call within a few days. If you see only small icicles and the attic and ceilings are dry, keep watching through the thaw and book an inspection after the melt.
What Not to Do After a Snowstorm
- Stay off the roof. Keep ladders away from snowy or icy gutters.
- Leave ice dams alone. Chisels, hammers and rock salt can damage shingles and gutters.
- Skip the snow shovel and metal roof rake. Both can damage the roof, and metal rakes are dangerous near power lines.
FEMA says that, more often than not, removing snow from a roof is more hazardous than helpful. Call an insured roofer if it needs to be cleared. If you clear a small amount yourself, use a non-metallic roof rake and keep both feet on the ground. Avoid power lines and sliding snow, pull snow down toward the eaves, and leave a layer over the shingles.
When to Call a Roofer for a Winter Roof Inspection
Once everyone’s safe, call about emergency signs or any of these.
- Active dripping or a new ceiling stain, even if it’s dry.
- Bent or detached gutters, or shingles, drip edge or flashing on the ground. Flashing seals joints around places like chimneys.
- Recurring ice dams. They point to heat escaping into the attic, so the fix is insulation and ventilation. Here’s how to prevent ice dams.
I start with the ceilings, attic insulation and ventilation. I’ll check the roof surface when it’s safe to walk, which may be after the melt. If a roof 20 years or older has a new leak or serious ice damage, I’ll talk through roof repair vs. replacement and put my recommendation in writing.
Frequently Asked Questions
What are the signs of roof damage from snow?
Once the snow melts, look for lifted, cracked or curled shingles, granules piled in the gutter and bent drip edge. A ceiling stain can take days to show up.
How much snow is too much for a roof?
There’s no single depth that tells you how much snow a roof can hold. FEMA puts a foot of fresh snow at 3 to 21 pounds per square foot, from dry powder to heavy, wet snow. An inch of ice adds just under 5 pounds per square foot, so watch for signs of roof stress.
Are ice dams covered by insurance in NJ?
Often the water damage is covered, but removing the dam isn’t. Dwelling coverage may pay for sudden water damage inside or a roof that sags under ice, while long-term maintenance problems are usually excluded. Check your policy and see the guide to roof insurance claims in NJ.
