From BuildZoom:

Roi Commercial Roofing Systems at P O BOX 623, Newcastle, CA 95658, held a Roofer license (#746762) with the California contractors license board with an expiration date of 04-30-2018. We last verified the license was revoked on 12-10-2025.

Their BuildZoom score is 0 because we haven’t been able to verify an active license. As a result, they’re not ranked in the top 50% of 336,931 California contractors.

If you’re thinking about hiring them, we recommend double-checking their license status with your local licensing authority. Alternatively, use our project planner to be easily matched to qualified, licensed professionals in your area.

    Quality Flat Roof Replacement

    George Stradiota of ROI Roofing is a very personable Businessman, as well as his crew. Other than the delay of start time due to inclement weather, the work done on my flat roof looks great and was completed in a timely manner....though we've had no additional rain yet.The crew also did not seem to mind me going up and checking on the progress,as well as answering any questions I had. The pricing was excellent as was the workmanship. I will update after the next heavy rainstorm the quality of the actual finished product, but for now I am quite pleased....Thanks again Mr Stradiota and your crew!
