Winter along New Hampshire’s Seacoast is beautiful, but it’s also tough on roofs. At Dover Roofing LLC, our family-owned team is ready year-round to help homeowners and businesses protect their properties from winter roof damage. With decades of hands-on experience across Dover and the surrounding Seacoast region, we understand exactly how snow, ice, and fluctuating temperatures affect local roofing systems, and how to stop problems before they escalate.
One of the most common cold-weather issues we respond to is ice dams. Below, we’ll explain how ice dams form on New England roofs, why they’re so destructive, and how our roofing services help with effective ice dam prevention and repair.
What Exactly Is an Ice Dam?
An ice dam is a ridge of ice that starts to form along the edge of a roof, usually near the eaves. As snow melts higher up the roof and refreezes near the colder edges, ice builds up and blocks proper drainage. When melting snow has nowhere else to go, it can force water back under shingles, a process known as roof water backup.
In New England winters, this cycle can repeat for weeks, allowing water to seep into roof decking, insulation, and interior spaces.
Why Ice Dams Are So Common in New England
Ice dams are especially prevalent in Dover and coastal New Hampshire due to a combination of weather and roof conditions:
- Heavy snowfall that accumulates quickly
- Freeze–thaw cycles caused by fluctuating daytime and nighttime temperatures
- Cold coastal winds that keep the roof edges frozen
- Extended winter seasons that prolong exposure
Even newer roofs can experience ice dams if snow buildup and temperature differences aren’t properly managed.
How Ice Dams Cause Winter Roof Damage
Once ice dams form, they can lead to serious and costly winter roof damage, including:
- Roof leaks and ceiling stains
- Damaged shingles and underlayment
- Rotting roof decking
- Warped fascia and soffits
- Interior insulation damage and mold risk
Because water backs up beneath the roofing materials, the damage often spreads silently before homeowners notice visible signs.
Signs You May Have an Ice Dam Problem
Not all ice dams are immediately obvious. Warning signs include:
- Thick ice buildup along the roof edges
- Icicles forming directly over gutters
- Water stains on interior walls or ceilings
- Drafts or moisture in the attic
- Dripping water during cold weather
If you notice any of these issues, prompt professional attention is critical to limit further roof water backup.
How Dover Roofing LLC Helps Prevent Ice Dams
At Dover Roofing LLC, we focus on practical, proven solutions rooted in proper roofing design, materials, and maintenance. Our ice dam prevention approach includes:
Professional Roof Inspections
We evaluate shingles, flashing, valleys, and roof edges to identify weak points where ice dams are most likely to form.
Durable Roofing Materials
We install and replace roofs using high-quality asphalt shingles, metal roofing, slate, cedar, and synthetic options that perform well in harsh winter conditions.
Emergency Roof Repairs
If ice dams cause leaks or sudden damage, our 24/7 emergency repair service allows us to respond quickly, minimizing interior damage and restoring protection.
Gutter and Drainage Support
Proper gutter performance plays a key role in managing melting snow. Our gutter services help ensure water is directed safely away from your roofline.
Long-Term Roof Replacement Solutions
For roofs that repeatedly suffer winter damage, a full replacement using cold-climate-appropriate materials may be the most effective long-term solution.
Ice Dams on Commercial Roofs
Ice dams aren’t limited to homes. Flat and low-slope commercial roofing systems, such as EPDM, TPO, PVC, metal, and asphalt, can also experience drainage issues during winter. Snow buildup combined with blocked drains can result in ponding water, leaks, and membrane stress.
Our commercial roofing team provides replacement, installation, and emergency repair services designed to keep Seacoast businesses protected throughout the winter months.
