This is a common local issue often caused by ice dams or compromised roof underlayment. As snow melts and refreezes at the eaves, it can force water under your shingles. If the protective underlayment beneath is damaged, water seeps into your attic. We perform targeted inspections to find the exact entry point and repair both the surface issue and the underlying barrier.

Underlayment is a water-resistant or waterproof barrier installed directly onto your roof deck beneath the shingles. In Grantham, it's your home's critical second line of defense against moisture from melting snow, ice dams, and driving rain. When it's damaged, even new-looking shingles can leak. We assess its condition during every inspection and recommend repair or replacement to ensure a complete seal.

Signs inside your home include water stains on ceilings or walls, especially after snowmelt. From the outside, look for curling or missing shingles, but often the damage is hidden. The best course is a professional inspection. We safely examine the roof deck from your attic for moisture and check for underlayment integrity, giving you a clear picture of any vulnerability before minor damage becomes a major repair.
