DeMARTINI ROOFING is your premier Nevada County Roofing Contractor.  Owned by Contractor Timothy DeMartini.

We are Licensed, Insured and Bonded. 

GAF Master Elite® Contractor – Through required annual factory training and advanced system education, our installations meet GAF’s highest standards, allowing GAF to stand behind our workmanship with a 25-year Golden Pledge® workmanship guarantee, in addition to a 50-year material guarantee.

Our approach prioritizes quality over speed. We intentionally do not overcrowd your roof with large crews just to complete a job in a single day. Instead, our projects are completed by a smaller team of skilled, in-house installers, allowing for tighter quality control and greater attention to detail. All of our roofing installers are on payroll and paid hourly, not subcontractors paid by the square, so there is no incentive to rush, cut corners, or sacrifice workmanship. While this process may take a little longer, it gives us full control over each phase of the installation—ensuring your roofing system is properly built, carefully inspected, and designed to perform reliably for decades
