Granule loss often appears as dark, gritty residue in your gutters or downspouts, or you may notice bare spots on your shingles. In Amherst, this is a critical issue because those granules protect the asphalt in shingles from UV rays. Without them, your roof becomes more susceptible to cracking and accelerated aging, especially during our freeze-thaw cycles. This damage can quickly lead to leaks, particularly after heavy snow melts. Our roofing experts can assess the extent of the granule loss and recommend targeted repairs or a replacement to restore your roof's integrity.

Old, drafty windows can contribute to ice dam formation, a major cause of roof leaks in Amherst. Warm air escaping from your home melts snow on the roof, which then refreezes at the eaves, backing up water under your shingles. Our professional window installation services provide a tight thermal seal, keeping warm air inside and maintaining a more consistent roof temperature. This helps prevent ice dams from forming in the first place, protecting your roof, walls, and interior from water damage caused by spring thaws and winter melt-offs.

First, we prioritize safety and containment. We'll quickly dispatch a team to safely access your roof, install a temporary tarp to stop immediate water intrusion, and assess the source of the leak—often around flashing, vents, or in valleys where snow and ice accumulate. Our comprehensive general contracting approach means we don't just patch the leak; we identify and fix the underlying cause, whether it's improper ventilation, damaged underlayment, or structural wear. We then coordinate any necessary interior repairs, like drywall or insulation, providing a single, reliable solution for Amherst homeowners.
