J J Devine Roofing, Masonry & Restoration | Masonry/Concrete & Roofing in Waltham, MA 02453

Yes, these are classic signs of poor roof ventilation, a common problem in Waltham homes. Inadequate airflow traps heat in the attic during summer and melts snow unevenly in winter, leading to ice dams. We assess your attic's intake and exhaust vents and can install solutions like ridge vents or soffit vents to regulate temperature and protect your roof structure.

Most leaks around chimneys are indeed caused by failing flashing—the metal seal between the chimney and roof. Over time, weather and wear can crack or lift the flashing. Our masonry and roofing teams work together to remove the old flashing, inspect the chimney for damage, and install a new, custom-fitted flashing system with durable sealants for a long-lasting, watertight repair.

Absolutely. As a full-service roofing and masonry contractor, we are uniquely equipped to handle the entire chimney leak repair process. Our masons address any brick or mortar deterioration on the chimney itself, while our roofing experts handle the flashing and surrounding shingles. This integrated approach ensures a seamless, high-quality fix that addresses all potential points of failure.
