A.W. Therrien Company: Reliable Roofing Services Serving Manchester, NH 03103

These are frequent concerns in our climate. For moisture in roof insulation, we conduct a thorough inspection to identify the source—often from ice dams, poor ventilation, or a compromised membrane. Our repair or replacement process prioritizes proper ventilation and vapor barriers to prevent recurrence. For granule loss on asphalt shingles, which accelerates wear, we assess whether it's normal aging or storm-related. We then recommend targeted repairs or a full replacement with materials suited for New Hampshire's weather, ensuring long-term protection for your home.

Our in-house fabrication shop handles custom projects using copper, aluminum, and stainless steel. We utilize laser and water cutting machines for precise fabrication of components like custom flashings, gutters, decorative elements, or specialized architectural metalwork. This capability allows us to create exact-fit solutions for both repair jobs and new construction, ensuring durability and a seamless integration with your existing or planned roofing system.

Yes, we provide complete roofing services. For a major repair or aging roof, a full tear-off to the deck is often the most reliable solution. We safely remove the old materials, inspect and prepare the deck, and install a new roof system tailored to your building. We work with various materials, including EPDM, PVC, modified bitumen, and metal, following industry standards for residential and commercial properties in the Manchester area.
