Rising PG&E rates and unreliable power turn a solar project into an energy-independence decision — not just an equipment purchase. Dura-Foam designs solar paired with battery backup, under one accountable roofing-and-solar contractor, so San Francisco homeowners stay powered, lower their bills, and own their system.
Solar panels alone lower your bills — but for safety, they shut off the moment the grid goes down. Without a battery, a San Francisco outage still leaves you in the dark. Pairing solar with battery storage is what turns your roof into a true backup power source.
Dura-Foam designs each system around your actual PG&E usage, your roof's condition, and your outage-backup priorities — then sizes solar and storage to work as one household energy platform rather than a panel count on a quote.
Homeowners who skip the roof inspection often pay twice for solar labor:
Our inspection is free. So is the peace of mind.
Most solar companies bolt panels onto whatever roof is already there — and hope it lasts the system's 25-year life. We're a roofing company first. That means your battery-backed solar system gets installed on a roof that's actually ready to carry it for decades.
For San Francisco's dense lots, flat roofs, and Eichler homes, that roof-first method matters even more — a solar array installed over a roof nearing repair age creates avoidable removal costs later, eroding the savings solar was supposed to create.
Schedule My Free InspectionThe grid isn't getting more reliable and PG&E rates aren't getting smaller. Here's what a properly designed solar-and-storage system actually protects you from.
No backup means lost food, lost work, and an unsafe home. Battery storage keeps your essentials running when PG&E goes down.
Time-of-use pricing keeps pressure on evening consumption. Solar plus storage gives you control over when you draw from the grid.
Install over a roof that soon needs replacing and you pay twice for labor. Roof-first planning prevents the costly do-over.
Drainage, mounting, and waterproofing tolerances are unforgiving on SF's flat roofs. We plan for them, not around them.
National installers push leases that keep you renting your own roof. We build systems you own — so the savings stay yours.
Eichlers and modern SF homes need roof-aware planning, not a one-size racking template forced onto the roof.
From first inspection to powered-on independence — no pressure, no surprises.
Roof, electrical panel, and shading conditions assessed. We confirm readiness or flag any pre-work.
A transparent system designed around production goals, battery options, and your home's real constraints.
We handle SF permits and interconnection with dedicated crews and clean jobsite standards.
Utility coordination, permission to operate, a full walkthrough, and an ongoing service relationship.
Design, permitting, installation, and long-term support from one Bay Area roofing and solar contractor — so nothing falls through the cracks between vendors.
"The system is working fabulously — it went through a winter with several power outages, and we usually don't even know we have an outage until PG&E informs us. What a relief."Astrid Gaiser
Headquartered in Menlo Park, under the same ownership since 1981 — so the team that installs your system is still here to support it years later.
Solar panels alone lower your bills, but for safety they shut off during a grid outage. If staying powered through PG&E outages matters to you, you'll want battery storage like a Tesla Powerwall or FranklinWH system. In San Francisco, storage adds the most value when you want evening resilience or want to shift energy use away from higher-priced utility periods. We'll help you decide based on your priorities and budget.
Cost depends on your system size, whether you add battery storage, your home's energy use, and your roof's condition. Because every home is different, we provide a free, customized estimate rather than a one-size-fits-all price. Owning your system typically delivers stronger long-term savings than a lease or subscription, because the savings stay with you instead of a third party.
If your roof is aging, the right move is to inspect it before finalizing equipment or financing. Roof-first planning minimizes future tear-offs because the solar layout is based on your roof's actual condition, not only the target system size. Our inspection is free.
Once permits are approved, the physical installation usually takes just a few days. The full timeline — including design, San Francisco permitting, installation, inspection, and PG&E interconnection — typically spans several weeks. We manage every step and explain the order clearly so you're never guessing.
Yes — these are our specialty. Flat roofs, low-slope profiles, and Eichler homes are common pain points for standard residential installers. Our engineering approach and leak-aware installation standards are designed for roof types where waterproofing discipline matters as much as panel placement.
Absolutely. We obtain all required San Francisco electrical and building permits, coordinate inspections, and manage your PG&E interconnection application so your system is fully compliant and ready to power on.
The smartest time to plan your system is before you commit to equipment or financing. A free roof-and-solar inspection gives you a cleaner project plan, a more accurate estimate, and a better basis for deciding system size, battery storage, and timing.
