Quick Answer: Skylight installation in San Jose costs $1,500-$4,000 for a standard fixed (non-opening) skylight installed through a sloped roof, or $3,000-$6,000 for a venting or solar-powered skylight (Velux VSE or VSS solar-powered). Cost factors include: the skylight size (larger = more expensive), roof type (tile roof costs $500-$1,500 more to cut and reseal vs. composition shingle), shaft construction if there’s attic space between the roof and ceiling (a tunnel shaft adds $500-$2,000), and flashing quality. A building permit is required in San Jose for skylight installation because it’s a structural penetration of the roof. Energy code: skylights must meet California Title 24 maximum U-factor (0.55 or better) and solar heat gain coefficient (0.30 or better). Velux and Fakro are the top two brands sold in the Bay Area — both offer factory-installed flashing kits for most roof types.
