Roofing in Davis, CA

Roughly 40% of Davis replacements we quote are explicitly tied to a solar install — either upgrading the roof before adding panels, or replacing a roof when the panels need to come off for service. We coordinate with the PV installer on mount-point spacing, conduit penetrations, and warranty paperwork.

Pre-marked mount-point locations on the underlayment let the PV installer place racking exactly where the roof structure supports it, with proper flashing detail that does not compromise the manufacturer warranty. Conduit pre-routing under the roof to the nearest J-box saves the PV team a separate trip + saves the homeowner a visible-conduit aesthetic compromise.

On homes with existing solar, we coordinate the panel removal + reinstallation with the original PV installer when possible. Most warranties on PV systems require the original installer (or an authorised service partner) to handle removal and reinstallation; doing it ourselves voids the warranty. Coordination adds 1-2 weeks of project lead time but preserves the PV warranty intact.

The 1940s-60s campus-adjacent homes have low-slope additions tucked behind the main roof. Most leak calls in those neighbourhoods are at the addition's flat-to-pitched transition. We use modified bitumen or TPO on the addition tied properly into the asphalt main roof.

Old North Davis is in a designated historic district — the city's preservation overlay protects visible exterior elements. We coordinate finish samples with the planning office before any visible work starts. Rear-roof work that is not visible from the street has fewer constraints; front-facing replacements need committee review.

College Park has a lot of bungalow homes from the 1940s with original or first-generation roof systems. Many have had partial replacements over the decades — we often find different shingle generations on different roof planes, which complicates matching aesthetics on a partial replacement. Full replacement to a single consistent material is usually the cleaner path.

Davis summers regularly hit 100 °F+ for stretches. A cool-roof rated shingle reflects more solar radiation than a standard one — attic temps run 15-25 °F lower, HVAC runs less, asphalt life extends 3-5 years on average. The cost premium over standard is 10-15%; the payback is usually 4-6 years from HVAC savings alone.

California Title 24 energy code enforces minimum cool-roof rating on most replacements. Davis enforces it strictly — the city plan-checker will reject a roofing permit that does not meet the cool-roof spec. We file the Title 24 certificate of installation as part of the permit closeout on every Davis project.

Beyond Title 24 minimum, several manufacturers make ultra-high-reflectance shingles ($200-400 premium per square) that perform even better. For Davis homeowners with high HVAC bills or older AC equipment, the upgrade often pays back faster than expected.

Downtown Davis has older brick-and-built-up commercial buildings with low-slope built-up roofs from the 1960s-80s. We do a lot of TPO and silicone coating overlay projects on these — full tear-off is cost-prohibitive for owner-occupied storefronts that need to stay open during work, and the coating overlay extends the roof another 10-15 years.

South Davis has newer master-planned commercial (Mace Boulevard corridor, the Sutter Davis Hospital area) with mostly TPO single-ply commercial roofs at 15-20 years now. Standard maintenance + repair work; replacement projects starting to come up in the next 2-5 years as those original installs reach end-of-life.

Asphalt replacement on a typical 1,800-2,400 sqft Davis home runs $13,000-19,000 with cool-roof rated shingles. Solar coordination adds $1,500-3,500 to the project total depending on panel count + installer coordination cost. Skylight + solar interaction analysis is included when relevant.

Commercial silicone coating overlay on a 5,000 sqft Davis storefront runs $25,000-40,000 typical. Full TPO replacement on the same building runs $45,000-70,000. The coating extends the roof 10-15 years; full replacement gives a fresh 20-25 year warranty period. We help building owners model both paths so the right one wins on the math.
