Residential & Commercial Roofing in Gilroy
While “solar” is in our company’s name, Simmitri Solar began as a roofing company and started implementing solar energy systems later at the dawn of the solar industry (you can read more on the Our Story page). With an extreme interest in utilizing solar energy wherever possible, we knew merging our roofing knowledge, and expertise in high-quality energy-saving solutions would be seamless.
As GAF Master Elite Certified roofers, we’re guaranteed to provide your Gilroy home or business with a stunning roof that looks good and can withstand the test of time, backed by iron-clad coverage.
Are you looking for something a little more environmentally friendly? We can implement additional features such as highly-reflective shingles to reduce the amount of heat absorption. Then there are our custom-built rain gutters and gutter guards. These are just a fraction of the different roofing services we provide for all our customers.

Solar Battery Storage in Gilroy
For your Gilroy home or business to properly manage and utilize solar energy, reliable battery storage is imperative. The last thing you need is to run out of power during an emergency or weather event where the primary grid is down. When it comes to batteries, you can rely on when it counts — lithium iron phosphate is our go-to choice.
Lithium iron phosphate batteries are non-toxic, completely recyclable, and offer superior storage capacity and power limits. Our battery storage options can be fine-tuned to meet the needs of your everyday life.

You can schedule your charging station only to operate when electricity usage rates are at their lowest to avoid hefty utility bills down the road. Preparing an in-house energy assessment will give us a clear idea of the best resources for your home or business.
