Some of the earliest warning signs are water stains on ceilings, damp attic insulation, missing or lifted shingles, and leaks that seem to show up after heavy rain or thawing conditions. In Cambridge, changing temperatures and seasonal moisture can make small roof issues spread faster than homeowners expect. At Aucoin Roofing, we inspect the full roofing system so we can identify where the water is actually getting in, not just where it becomes visible inside the home.
