Lorenzano Sheet Metal, Inc. fabricates and installs standing-seam metal roofing, seamless gutter systems, metal wall siding, and custom sheet metal components from its San Diego shop at 4990 72nd Street in College Area. Founder and president Juan Carlos Lorenzano incorporated the business in 2019 and holds CSLB license #1060615 under the C-43 Sheet Metal classification, backed by a $15,000 surety bond through American Contractors Indemnity Company. The crew brings over 30 years of combined sheet metal fabrication experience to residential and commercial projects across the 92115 ZIP and greater San Diego County. Standing-seam metal roof installations use Galvalume steel panels with concealed-fastener clips, producing a watertight surface rated for 40-plus-year service life that outlasts the asphalt-shingle roofs common on College Area's mid-century housing stock. Tear-off and underlayment work that precedes the metal panel phase coordinates with Colin's Emergency Roofers in Grantville, whose strip-and-prep crews clear the old roofing material before the Lorenzano team begins panel installation. Seamless aluminum gutter runs are roll-formed on-site to the exact linear footage of each roofline, eliminating the seam joints that cause leaks in sectional gutter systems. Downspout routing, rain barrel hookups, and leaf-guard screen installation complete the water management package. Custom fabrication services extend to metal capping, flashing, wall siding panels, and specialty trim pieces cut and bent in the 72nd Street shop on a mechanical brake and shear setup. The shop's location near SDSU places it within the residential belt where homeowners converting from shingle to metal roofing often coordinate solar panel reinstallation on the new standing-seam surface, since clamp-mounted solar racking attaches to standing seams without penetrating the roof membrane. Gutter maintenance calls that reveal corroded or sagging runs beyond repair generate replacement referrals, and Caliber Gutters in San Carlos is one of the cleaning operations whose inspection findings feed into the Lorenzano crew's gutter replacement queue. BuildZoom ranks the company's CSLB license in the top 15 percent of California's 336,000-plus licensed contractors based on verified work history and complaint record.
