All Seasons Roofing & Siding | Roofing Services in Northwood, NH 03261

This is a common issue in our area due to the freeze-thaw cycle. Snow accumulates on your roof, and as it melts, water can seep under shingles and into small cracks. If ice dams have formed at the eaves, they trap this meltwater, forcing it back up under the roofing material. Our team specializes in identifying the exact entry point—often around flashing, vents, or in valleys—and performing a permanent repair to prevent recurrence.

Adequate ventilation is crucial for regulating your attic's temperature and moisture levels. In winter, a cold, well-ventilated attic helps prevent snow from melting unevenly and forming ice dams. In summer, it expels hot air, reducing strain on your AC and preventing shingles from overheating. We assess your current ventilation (soffit, ridge, and gable vents) and recommend solutions, like installing additional vents or attic fans, to protect your roof's structure and improve your home's energy efficiency.

We advise Northwood homeowners to perform seasonal visual checks. After winter, look for missing or cracked shingles, sagging areas, and granules in gutters. Inside, check your attic for water stains, mold, or daylight coming through the roof boards. Persistent icicles or ice dams along the eaves are a red flag. If you notice any of these signs, it's best to call us for a professional inspection. Early detection of small issues can prevent costly repairs from water damage later.
