Some of the most common signs include recurring leaks, shingles that are curling or going missing, visible wear across larger sections of the roof, and ongoing issues around flashing or ventilation. In Cambridge, roofs also deal with freeze-thaw cycles, snow load, and humidity, which can make aging problems worse over time. At Aucoin Roofing, we inspect the full roofing system and help determine whether the roof still has life left in it or whether replacement is the smarter long-term choice.
