Faded, patched shingles, old turbine vents and a rusted metal vent box on the ridge? On this brick ranch home in Portsmouth, our crew tore the old roof down to the deck, cut out the damaged sections and replaced them with new OSB sheets, installed new drip edge, and put on a new CertainTeed Landmark architectural shingle roof with a continuous ridge vent and new pipe boots. Every job starts with a free inspection and a written estimate.
