A full roof replacement means stripping the old roofing material down to the deck, checking that deck for rot or soft spots, repairing or replacing damaged sheathing, then installing new underlayment, flashing, ventilation, and the finish material (composition shingle, tile, or metal, depending on the house). Installation jobs, meaning a first-time roof on a new addition or structure, follow the same sequence but start with a bare deck. Either way, the work is done in a day or two for most single-family homes in Citrus Heights, though tile re-roofs and complicated rooflines take longer.
Summer heat and the occasional heavy winter storm both put real stress on roofs here, so the details matter more than they might in a milder climate: proper attic ventilation to keep shingles from baking from underneath, correctly lapped flashing around valleys and chimneys, and underlayment rated for the material on top. A buyer should ask for a written scope of work, proof of a valid C-39 roofing license and current liability insurance, and a clear breakdown of tear-off, disposal, and warranty terms (both the manufacturer's material warranty and the contractor's workmanship warranty).
