Major flat roof transformation in Haverhill, Massachusetts, converting a heavy, aging gravel built-up roof system to a clean, modern EPDM rubber roof. The existing gravel roof was stripped completely down to the deck — a labor-intensive removal due to the weight and age of the original material. Once the deck was clean and inspected, we installed a brand-new 1-inch polyiso insulation board to provide thermal performance and a smooth, level substrate, followed by a fully adhered EPDM rubber membrane for a seamless, watertight finish. EPDM is one of the longest-lasting flat roof systems available, offering excellent UV resistance, weatherproofing, and a clean, professional look. A complete top-to-bottom system replacement built for decades of reliable performance.
