Those black streaks are Gloeocapsa magma algae, common here due to humidity. We use a professional, low-pressure cleaning solution that safely kills the algae without damaging your shingles. It's important not to use a high-pressure washer, as that can strip the protective granules and void your shingle warranty. A treatment can also be applied to help prevent regrowth.

Prevention starts with proper attic insulation and ventilation to keep your roof deck cold and even. We inspect your attic to identify heat loss and can recommend upgrades. For existing ice dams, we perform careful snow removal and, if damage is found, provide targeted repairs to the underlying roof deck and shingles to prevent water from seeping into your home.

First, try to safely contain any interior water and document the damage for insurance. Then, call us for an emergency inspection. We'll assess the extent of the damage to the shingles, underlayment, and decking. In Watertown, quick action is key to prevent mold and structural rot. We provide temporary fixes to stop further leaks and a clear plan for permanent repair once things thaw.
