Ice dam roof repair is a winter problem in Newark, DE, but most of the work that prevents it happens before the first snow. An ice dam is a ridge of ice that forms along the bottom edge of a sloped roof. When it grows, the next round of melting snow has nowhere to go and backs up under the shingles.
This guide explains how ice dams form, the signs to look for on a Newark house, what to do once one has formed, and what a roofer checks before winter. The sources are the National Weather Service, Wikipedia and our own published roof jobs.
How an ice dam forms on a Newark roof
Wikipedia describes an ice dam as an ice build-up on the eaves of a sloped roof on a heated building. Heat from the house warms the upper part of the roof, the snow there melts, and the water runs down toward the eave. The eave hangs out past the walls, where there is no building heat, so the water freezes again when it gets there. Each melt adds to the ridge.
The National Weather Service office in Grand Rapids, Michigan, describes the same cycle in its page "Preventing Roof Ice Dams": heavy snow melts during the day and refreezes when temperatures drop overnight. After a few of those cycles, water and ice work their way under the shingles.
Wikipedia lists three conditions that have to line up: air well below freezing, a thick layer of snow on the roof, and heat escaping from the house through the roof. Take any one away and an ice dam cannot form, so two houses on the same street can look very different after the same snow.
Why an ice dam turns into a roof leak
Shingles are made to shed water that runs downhill. They are not made to hold back a pool of standing water. When meltwater backs up behind the ice, it can get under the shingles and into the attic, and from there it can reach the ceilings, walls and insulation (Wikipedia; National Weather Service).
The first few rows of shingles at the eave are where this happens, which is why ice and water shield goes under the shingles in those critical areas on our roof installs. Wikipedia notes that a roofing membrane like this helps prevent leaks from ice damming, but it does not stop the ice from forming.
An older roof may have no membrane at the eave at all. On the Magnolia job above, the roof went on before ice and water shield was standard, and the leaks were around the perimeter. The house is in Magnolia, not Newark, but an older roof in Newark can be built the same way.
Signs of an ice dam on your Newark house
- A thick ridge of ice along the roof edge or packed into the gutter, with snow still sitting on the roof above it.
- Water stains, drips or peeling paint on an upstairs ceiling or wall near an outside wall during a cold, snowy stretch.
- Damp or matted insulation in the attic just inside the eaves.
- Shingles at the bottom edge that are lifted, cracked or missing once the ice melts off.
One of our Google reviewers describes the last one: after an ice storm, the ice stayed on the roof for an extended time and shingles came off when it started to melt. That review does not name a town.
What to do when an ice dam has formed
Start from the ground. The National Weather Service recommends a long-handled roof rake to keep the snow on your roof to a minimum. Wikipedia adds that the whole roof has to be cleared, because shoveling only part of it can leave a new dam where the snow was left.
Do not go at the ice with a hammer or chisel. Wikipedia notes those are likely to damage the roof, and an icy roof is no place to stand.
Inside, catch the water, move what you can out of the way and take photos and videos of any damage with the date on them. A record like that helps if you talk to your insurance company later. Whether a policy covers ice dam damage is your insurer's decision under your policy, and we do not promise what a claim will pay.
Heading off ice dams before winter
The National Weather Service lists the steps that keep the roof cold and the water moving: clean leaves and debris out of the gutters and downspouts, keep snow and icicles out of them through the winter, and improve attic insulation and ventilation so air moves from the soffits out through the roof vents. It suggests talking to a roofing or insulation contractor about the insulation and ventilation.
We do not clean gutters. We do install new seamless gutters and gutter guards, and we look at the eave and the flashing during the free roof inspection.
If the roof is due for replacement anyway, the eave is the place to get right. On a rear addition roof in our June 23, 2026 Google profile post, we put ice and water shield in the critical areas and synthetic underlayment under the new shingles.
How we handle ice dam roof repair in Newark
Newark is in our service area, whether your house sits on the hilly north and west side of the city or on the flat ground to the south and east. The roof inspection is free. We photograph the roof by drone so you can see the eave, the shingles and the flashing yourself, and we separate what has to be fixed now from what is only a recommendation.
If the damage is limited to the eave, a roof repair may be all it needs. If the roof is older and has no membrane at the edge, we will tell you that too, and you can read about our roof replacement options. For more about our work in the city, see roofing services in Newark, DE.
