Residential & Commercial Roofing Services in San Diego, CA

We install, repair, replace, and maintain roofs across San Diego County, both residential and commercial. That covers asphalt shingle and tile roofs on pitched homes, plus the flat and low-slope systems (torch-down, hot mop, coatings) common on mid-century houses, room additions, and commercial buildings around San Diego. We also do leak detection and roof inspections, which matter here because our leaks tend to show up all at once: a roof can look fine through eight dry months and then fail during the first real storm in December. An inspection in the fall, before the rain arrives, is the cheapest service we offer and the one that prevents the most damage.

Some signs are universal: water stains on ceilings, missing or curling shingles, sagging areas. Others are specific to San Diego. Heavy granule loss in your gutters usually means UV exposure has worn out the shingle surface, which happens faster in the sunnier inland neighborhoods. After a Santa Ana wind event, look for lifted or creased shingles and slipped tiles. Near the coast, rust on flashing and vents is an early warning, since salt air corrodes metal well before the roof itself fails. On flat roofs, ponding water that lingers days after a storm means the drainage or membrane needs attention. If you’re seeing any of these, an inspection will tell you whether it’s a repair or a replacement conversation.

A straightforward shingle replacement on a typical San Diego single-story home usually takes two to four days, weather permitting, and our weather permits most of the year. Tile work takes longer: a lift and relay, where we salvage your existing tile and replace the underlayment beneath it, can run one to two weeks depending on the roof’s size and complexity. Flat roof replacements typically fall somewhere in between. Repairs are often finished in a day. We’ll give you a schedule in writing before work starts, and because San Diego’s rainy season is compressed into a few winter months, we plan jobs so your roof is never left open when a storm is in the forecast.

Yes. Hercules Roofing is licensed by the California Contractors State License Board (license #1076561, which you can verify yourself at cslb.ca.gov), and we’re bonded and insured. This is worth checking for any roofer you talk to: after big storm years, San Diego sees a wave of door-knockers and out-of-area crews quoting cash jobs without a license. An unlicensed roof job can void manufacturer warranties, complicate insurance claims, and create liability for you if a worker is hurt on your property. Two minutes on the CSLB website protects you from all of that, whoever you end up hiring.

Asphalt shingles remain the most popular choice for pitched roofs, and we install cool-roof-rated shingles that reflect more heat, which makes a real difference in warmer inland areas and helps meet California’s Title 24 energy standards. Clay and concrete tile suit the Spanish and Mediterranean style homes common across the county, and often the existing tile can be reused over new underlayment. For flat and low-slope roofs we install torch-down and hot mop systems and apply restorative coatings. If you’re in one of East County’s higher fire-risk areas, we’ll steer you toward Class A fire-rated assemblies. We stock materials from Owens Corning, CertainTeed, Malarkey, and Polyglass, and we’ll walk you through what fits your home and budget.

Yes, on both materials and workmanship. Because we hold installer certifications with the major manufacturers we carry — Owens Corning Preferred Contractor, CertainTeed Master Shingle Applicator, Malarkey Certified Residential Contractor, and Quantum contractor with Polyglass — we can register manufacturer-backed warranties that aren’t available through non-certified installers. Those certifications also mean the manufacturer has vetted our installation work, which is what keeps a warranty valid: most roofing warranty disputes come down to installation errors, not bad material. We’ll explain exactly what’s covered, for how long, and by whom, in writing, before you sign anything.

Yes. A new roof can be financed from around $300 a month, with no payments for the first 12 months, and we offer flexible plans beyond that. We know most people don’t replace a roof because they want to; they replace it because a ceiling stain or an inspection report forced the issue. Financing lets you fix the problem properly now instead of patching it every winter. Ask about current terms when you schedule your free estimate, and we’ll lay out the options with no pressure attached.
