A correction-of-a-correction project. The existing 2.5/12 pitch section had asphalt shingles installed on it — a roof pitch where shingles simply don't belong. The result was exactly what you'd expect: moisture intrusion, mold, and deteriorated decking. The homeowner needed it rebuilt the right way, top to bottom. We stripped the entire section down to the rafters — shingles, underlayment, flashing, and all the compromised plywood removed to expose the framing. From there, we replaced the insulation between the rafters with new code-compliant batts (R-30 or greater, properly fitted with no voids), then installed brand new 1/2" CDX plywood decking, fastened per MA code with proper expansion spacing. On top of the new deck, we added 1/2" polyiso insulation board — mechanically fastened with staggered seams — to improve thermal performance, reduce condensation under the membrane, and provide a smooth, flat substrate. Then came the membrane itself: a .060 reinforced EPDM system from Mule-Hide, fully adhered with bonding adhesive, with every seam cleaned, primed, and taped, every penetration properly flashed, and termination bars set 6" on center with water cut-off mastic behind them. New drip edge, properly integrated wall terminations, and OC ridge vent with matching hip and ridge shingles where the EPDM meets the sloped roof finished the assembly. The homeowner also opted to bring in a mold remediation specialist once the rafters were exposed — we coordinated timing so they could treat the framing before we installed the new decking. The result: the right roofing system for the pitch, eliminated shingle failure risk, mold-compromised materials gone, improved insulation, and a long-term watertight membrane — backed by a 20-year Mule-Hide material warranty and a 5-year MDR workmanship warranty.
