Stunning, Efficient Roofing & Solar
Services For Danville Residents

Our Energy Solutions Are Geared Toward Ensuring A Cleaner Future

Tucked away from the hustle and bustle of Oakland and San Francisco, Danville is a wonderful little town that somehow managed to avoid the influx of tourism that California experiences nearby. That being said, Danville has so much to offer those living in and around the area.

And one thing all home and business owners in Danville have in common?

They all have a roof over their heads!

Sure, that may sound like a given, but most people never think about their roof until a problem starts to show itself. If you’re interested in adding solar to your home or business, ensuring a durable roof is the first step. Lucky for you, we’re experts in roofing, solar, and energy management services.

“The Simmitri team are very professional and know this field very well. They helped my facility get our solar panels back online with no issue. Great customer service and great people to work with!”

Residential & Commercial Solar

If you’re an environmentally conscious person, want to reduce your reliance on the main power grid, or simply want to reduce operating costs — our solar energy systems are for you. We have been installing our revolutionary solar panel systems for Danville residents since 2009 and have become the longest-running solar and roofing company in the area.

Our efforts towards optimizing a home or business’s “green level” don’t start and end with solar panels. We implement a long list of energy-saving devices, technologies, and best practices to reduce the carbon footprint wherever possible.

Residential & Commercial Roofing

Way back before we were Simmitri Solar, we used only to offer roofing services and quickly earned the Triple Excellence Award from GAF for our impeccable installations. Soon after, we were inducted into the GAF President’s Club and ranked as Master Elite Roofers.

We still offer those same exceptional roofing services today for Danville home and business owners while using industry-leading products every step of the way.

Our GAF Lifetime Roofing System offers enhanced curb appeal, energy efficiency, custom-designed gutters and gutter guards, and much more. Your Danville home or business will be a money-saving machine with our many energy-saving features to choose from.

Residential & Commercial Battery Storage

Once your roof is deemed suitable for solar, it’s time to figure out how to store all the energy you draw from the sun. Our state-of-the-art battery storage system utilizes ethically-mined lithium iron phosphate batteries, the safest batteries available for Danville residents.

Reliable power when you need it most — that’s the Simmitri guarantee.

Residential & Commercial EV Smart Charging

Our state-of-the-art EV Smart Charging units can be completely monitored and controlled via mobile device with brilliant software that includes fail-safe measures, energy usage control, and much more. Home and business owners can benefit from having one or more EV Smart Charging units. From a business standpoint, giving customers a place to charge their cars while shopping, for example, will encourage them to spend more time in your establishment.

“Simmitri was professional, responsive, and did a high-quality job. I shopped around before deciding which company to use for our solar panel job, and this company blew away the others. They are actual solar nerds — not just looking for a sale — which is what I was looking for. I highly recommend them.”
