A L Hanson Roofing Co in Bonita holds CSLB license #263346 under the C-39 roofing classification, covering residential re-roofing and repair work on the hillside homes along La Cresta Way and surrounding streets in the 91902 ZIP. Drywood termite damage is the most common trigger for emergency re-roofing in Bonita's wood-framed housing stock, a structural overlap where pest inspection firms such as Nixtermite Inc. identify compromised fascia, sheathing, and rafter tails during escrow-phase WDO reports. The company's permit history with San Diego County includes tear-off-and-replace projects on asphalt composition shingle roofs and concrete tile systems found on the single-family residences that characterize the Bonita hillside between Sweetwater Road and Bonita Golf Club. Post-installation exterior painting of exposed fascia, barge boards, and stucco patches around new flashing details is a standard follow-on scope that contractors such as Montgomery Paint Contracting coordinate after the roofing crew clears the site. Crews install 30-pound ASTM D4869-compliant felt underlayment beneath composition shingles and apply ice-and-water shield membrane at all valleys, eaves, and pipe penetrations per California Building Code Section 1507.2 requirements for the San Diego coastal climate zone.
