We’re in Arlington on a full roof replacement, tearing off the old shingles down to the decking so we can inspect what’s underneath and address everything needed.

This roof has no ventilation, no soffits for intake airflow, and an attic fan that isn’t working. We’re adding intake vents along the eaves and a new ridge vent up top, then finishing with a CertainTeed Landmark Pro roof.
