Professional Team with Extensive Experience

At Capstone Roofing, the foundation of our success is the dedicated team of professionals who perform every project. Many of our roofers have been with the company for over 15 years, bringing long-term knowledge, consistent teamwork, and accountability to every commercial job. Unlike contractors who rely on outside labor, we complete our projects with our own crews who understand the high standards we uphold. Our company is both GAF Master Elite and Diamond Certified, credentials that reflect rigorous training, industry-leading installation practices, and strong customer satisfaction. Combined with more than 35 years of reputation, this expertise ensures that Napa businesses receive commercial roofing installed with precision and care.

Roof Replacement

Our crews are trained for efficient, clean, and quality-focused roof replacements using trusted materials.

Commercial & Flat Roofing

We provide reliable solutions for commercial properties, flat roofs, and specialized systems like TPO and single-ply membranes.

Emergency & Urgent Repairs

Capstone Roofing offers emergency repair services, day or night, to protect your property when the unexpected strikes.

High-Performance Systems and Quality Materials

Commercial properties in Napa demand roofing systems that can withstand both heavy use and the regional climate. That is why Capstone Roofing installs TPO and single-ply systems designed for flat and low-slope roofs, materials known for their energy efficiency, durability, and cost-effectiveness. These systems reflect heat, reduce energy expenses, and require minimal maintenance over their lifespan. For properties that need alternatives, we also provide asphalt and composition roofing tailored to meet specific design or functional needs. Every installation uses products from established suppliers and follows strict manufacturer guidelines for flashing, fasteners, and overall detailing. The result is a commercial roof that provides lasting performance, protects property investments, and meets the high standards of Napa’s business community.
