What Other Bay Area Customers Are Saying

“I hired Simmitri to replace our roof and install a solar system, including batteries. They’re as knowledgeable as any roofing contractor and more knowledgeable than any other solar contractor. Their straightforward and honest answers gave me confidence. Simmitri did an outstanding job. They had separate teams for each task -- roof demo, roof construction, gutters, solar & batteries. They’re hard-working and pay attention to quality. Every employee was pleasant to deal with, they worked quickly, and the workmanship was excellent.”

Alan A.

“I looked at a few companies before hiring Simmitri for a new roof, gutters, and solar, and I’m so glad I did! My Sales Consultant had amazing patience and was always available to answer questions. Throughout the process, I dealt with many different individuals who all took pride in their jobs, and the end result is simply phenomenal. Everyone was responsive from the operations side, and from start to finish, the production team was efficient and polite and worked hard to keep the area around our house clean. The solar installation and permit process went better than expected. I can't believe how quick the job went and how nice everyone was.”

Shannon L.

“It's been a long time since I've had such professional work done and amazing service. Simmitri got the right financing program for my needs, and the entire project was done in a very short time. Very responsive, clean job, and stellar communication by everybody across the company. I’d recommend to anyone who needs solar or roofing in the Bay Area.”

Bernard L.

“After interviewing three solar companies, I selected Simmiti for my solar installation. The planning and submissions were done in a timely manner. The installation crew was superb. The inspector was highly impressed with the installation. My PM stayed on all parties to get the final steps of approvals. I highly recommend Simmitri for your solar project.”

David M.

“If you’re looking for a trustworthy company for a roof and/or a solar system, I strongly recommend Simmitri. I hired them for a new roof and a solar system for my home, and have no regrets. They’re experienced pros in roofing and solar system design & installation. In my case, there were several issues with PG&E and the San Jose city permit process. But Simmitri’s been honest and sincere. Most issues weren’t their fault, but one, and they honestly admitted their oversight and took action. Even their CEO and COO contacted me directly. I’d say it’s rare to find such a sincere company these days.”

Integrated Solar Roofing FAQs

Important Points For Your Research

Will Our Solar Roofing System Qualify For A Tax Credit?

YES, tax credits are available for this integrated solar roofing system/product! If you want to learn more about these tax credits and what other products can qualify for your home, please contact Simmitri’s energy team at (408) 779-3333 or email [email protected] for more details.

What Is The Federal Tax Credit For A Solar Roof In 2023?

The tax credit for solar was originally scheduled to decrease to 22% in 2023. With the recent signing of the Inflation Reduction Act of 2022, not only will the credit still be available, but it will also increase to a 30% credit effective until at least 2032.

Can I Write Off The Roof Replacement On My Taxes?

A roof replacement can fall under the category of home improvement if it meets the IRS criteria for a capital improvement. If your roof replacement increases your home's value, extends its useful life, or adapts it to new use, it may qualify as a tax-deductible expense. Consult your tax professional directly to confirm.

What Happens After I Pay Off My Solar Roof?

Once you pay off your loan or buy your system outright, you’ll essentially be getting energy for free. When it comes to payment, those who are using solar energy will still get a monthly utility bill. This will show how much energy you produced versus how much energy you used for the month.
