Green roofing lowers the heat your attic absorbs and the money your air conditioner spends removing it. On flat sections we install reflective TPO or EPDM membrane; on pitched roofs we use cool-rated architectural shingle or standing-seam metal panel. We also build roof-garden assemblies where the decking can carry the load.
Concord's hot, dry summers and occasional fire-season winds age a dark roof fast. A reflective surface stays cooler at peak sun, which slows granule loss, asphalt oxidation, and the peeling and flaking that follow. Cooler decking also means less thermal movement, so sealant at the flashing and ridge cap lasts longer between visits.
Winter is the other half of the job. Heavy downpours find every weak lap in the underlayment and every clogged gutter, so we check the eave, valley, and downspout before quoting. A green assembly only pays off when the roof below it is watertight first.
