San Jose Roofing & Solar Energy Experts for Home and Businesses

Solar and Roofing Services Rooted in San Jose

San Jose is Simmitri's home turf. Our crews work across the city regularly — from the tree-lined streets of Willow Glen to the hillside neighborhoods of Almaden Valley and the sprawling ranch homes of Berryessa — so we understand the rooftops, the permit timelines at the City's Development Services Department, and the PG&E rate structures that shape every project here. Because we're already active throughout Santa Clara County, we're not a distant contractor dispatching a crew for a one-off job. We're a familiar name on local rooftops, and our response times reflect that. Whether you're exploring solar for the first time, dealing with a roof that's overdue for replacement, or looking to pair a battery system with an existing array, Simmitri brings the local knowledge and full-service capability to get it done right.

Why San Jose Residents Choose Simmitri

Simmitri holds a 5.0-star rating across 101 Google reviews — not because we overpromise, but because we follow through. Customers consistently highlight our responsiveness, our knowledgeable crews, and the quality of our post-installation support. One longtime customer noted that after two separate solar installations, the experience from sales through post-install support was excellent start to finish. Another praised how well Simmitri handled a situation where a previous contractor had gone bankrupt, stepping in with professionalism and care. A third highlighted that their Enphase solar and battery system has run without issue for three years — and that our office even helped with California document submissions.

That last detail matters in San Jose, where Title 24 energy code compliance and City permitting requirements add real complexity to any solar or roofing project. We've navigated those processes hundreds of times, and we handle them so you don't have to.

• Authorized installer for Enphase solar and battery systems

Why Local Expertise Makes a Real Difference in San Jose

San Jose's climate is genuinely exceptional for solar production — roughly 300 sunny days per year and an estimated 4,500–5,000 peak sun hours annually place it among the most solar-productive metro areas in the state. In inland neighborhoods like Almaden Valley and Evergreen, summer temperatures regularly push into the mid-90s°F, driving air conditioning loads that a properly sized solar system can directly offset. For many households, that summer peak production lines up almost perfectly with the highest-cost hours on PG&E's rate schedule.

But the local picture isn't just about sunshine. San Jose's housing stock tells its own story. A significant share of the city's single-family homes — particularly in Willow Glen, Cambrian Park, and Berryessa — were built between the 1950s and 1980s. Composition shingle roofs from that era are frequently at or past their 20–30 year service life. Installing solar on a roof that has five years of life left is a costly mistake; re-roofing and solar in a single coordinated project is almost always the smarter path, and it's one we've executed many times across the city.

East San Jose and Alum Rock add another layer of complexity: many homes there feature flat or low-slope roofs that require different waterproofing systems and mounting approaches than a standard pitched composition roof. Our team is experienced with both.

The rainy season — roughly November through March — is when aging roofs make themselves known through leaks, lifted shingles, and compromised flashing. We see a predictable uptick in combined roofing-and-solar inquiries in late winter and early spring, and because San Jose's mild winters allow year-round rooftop work, there's rarely a reason to wait.

Finally, California's NEM 3.0 net metering policy, which took effect for new solar customers in 2023, changed the math on grid-tied solar meaningfully. Export credits are lower than they were under NEM 2.0, which has made battery storage systems — like the Tesla Powerwall or Enphase IQ Battery — far more financially attractive for San Jose homeowners who want to maximize self-consumption and protect against outages. We help customers model both scenarios before they commit.

The Team Behind Your Project

Simmitri's San Jose-area team includes experienced project managers, licensed roofing installers, and certified solar technicians who collectively have handled hundreds of installations across Santa Clara County. Frank and the field crew have earned specific recognition from customers for going above and beyond — including work for organizations as notable as the National Marine Fisheries Service/NOAA — and that same standard of care applies to every residential and commercial project we take on.

Our office team manages permitting, utility interconnection paperwork, and California incentive documentation in-house, which means you're not left navigating the City of San Jose's Development Services portal or PG&E's interconnection queue on your own. We've done it before. We handle it for you.
