Capstone Roofing is amazing. They sent an army or workers out to strip and re-roof my 2400 sq ft house.

Commercial Roofing Built to Last
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.
What a pleasure. I am retired, but worked in the construction industry, and thus I know how it should be.

Frequently Asked Questions
What is the commercial roof permit process through the Napa Building Department?
The Napa County Building Department requires all commercial building permit applications, including re-roofing, to be handled digitally through their Online Permit Center. Commercial roofs require a Submittal Application that goes through a plan review to ensure compliance with the latest California Building Standards Codes.
How does extreme heat affect commercial roofs in Napa?
Napa Valley experiences blistering hot temperatures and continuous ultraviolet radiation. This relentless solar exposure breaks down the chemical bonds in traditional roofing membranes, causing them to dry out, chalk, blister, and crack under the stress of daily thermal expansion and contraction.
What is the best color roof to avoid heat in Napa?
A bright white, highly reflective roof is unequivocally the best option for Napa’s hot climate. White TPO membranes act as cool roofs, reflecting harmful UV rays back into the atmosphere rather than absorbing them. This keeps your commercial building significantly cooler and slashes air conditioning costs.
How much does a commercial roof replacement cost in Napa?
Pricing for a commercial flat roof replacement in Napa depends heavily on the extent of the tear-off and required insulation upgrades. For a premium, energy-efficient TPO roofing system, the average installed cost ranges from $7.00 to $14.00 per square foot. Capstone Roofing provides honest, mid-range pricing through completely free estimates.
