Asphalt shingleroof replacementbuilt from the deck up.

Architectural shingles are the default for good reason: they handle our freeze-thaw cycling, they are repairable, and a properly installed and ventilated roof gives twenty to thirty years here. What varies enormously is what goes on under them. We tear off every existing layer, expose the decking, and walk it — soft sheathing, delaminated plywood and old repairs that were never flashed all get replaced before anything new is laid.

Then the assembly: ice-and-water membrane at the eaves, in the valleys and around penetrations, synthetic underlayment across the field, a starter course at the eaves and rakes, new step flashing against every wall, new counter-flashing cut into the chimney, and the shingles themselves nailed to the manufacturer’s pattern rather than to whatever is quick. Hip and ridge caps are purpose-made pieces, not field shingles cut down, because a cut shingle on a ridge is where a roof starts failing first.
