Commercial Reroofing
Offering excellence in service and craftsmanship for reroofing services.
Commercial reroofing gives a building a new roof covering, either as a recover laid over the existing roof or as a full tear-off. GoGreen Roofing, based in Santa Clara, checks which one a roof qualifies for on commercial buildings across California and the Western U.S. California code allows a recover only over a single existing roof layer that is dry and sound, and never over tile or slate.
Cut Down on Costs With GoGreen’s Commercial Reroofing Services
At GoGreen Roofing Corp., we specialize in commercial reroofing services across the Western United States, including reroofing in California. Commercial reroofing allows you to maintain your roof’s structural integrity by adding a new layer over the existing one, provided the roof qualifies and meets safety standards. This process avoids the need for a complete tear-off and is a faster, less disruptive solution compared to a full replacement.
With reroofing, we ensure that the roof meets all necessary fire safety ratings and building standards, which is especially important for commercial properties. Our team evaluates the current condition of your roof and determines if it’s suitable—factoring in the number of layers and structural soundness. When applicable, it can help you save both time and money, making it an efficient solution for many businesses in California and throughout the Western U.S.
Streamline and Expedite the Commercial Roofing Process
Reroofing is faster and more efficient than a complete roof replacement, making it the perfect choice for businesses that want to avoid extended downtime. Since we can often install the new roof directly over the existing system, the process is less invasive and helps reduce the overall project timeline. At GoGreen, we ensure the process is handled smoothly and efficiently, allowing you to continue your operations with minimal disruption.

Reroofing FAQs
What is the difference between reroofing and roof replacement?
Reroofing can involve the complete removal of your existing roofing system or the placement of a new layer of roofing material over an existing roof, provided the current structure is in good enough condition and meets local, state, and federal guidelines. A roofing system overlay is a faster, more cost-effective option that doesn’t require tearing off the old roof. On the other hand, a roof replacement involves completely removing the existing roof before installing a new one, which is necessary if the roof has significant damage or multiple layers of material that make reroofing unsafe or unfeasible.
Can you reroof over any type of existing roofing system?
Not all roofing systems are suitable for reroofing. While many types of roofing materials, such as shingles, TPO, and PVC, can be reroofed, the existing roof’s condition is a critical factor. The roof must be structurally sound, with only one layer of roofing material already in place. A complete roof replacement might be safer and more appropriate if the roof has more than two layers or extensive damage.
Does reroofing extend the lifespan of my roof?
Well, yes and no. We wouldn’t consider re-roofing an “extension” of your existing roof; rather, it’s best to see it as a whole new roof with its own life span and newly constructed system.
When does a commercial roof need a full replacement instead of a recover?
Under California Building Code Section 1512, a recover is not allowed when the roof already has two or more layers of roof covering, when it is water-soaked or deteriorated, or when it is slate or clay, cement or asbestos-cement tile. In those cases we tear the old roof off down to the deck and install a new one. See our commercial roof replacement service.
Can an industrial facility be reroofed while it keeps operating?
Reroofing is designed for that. Because an overlay skips the full tear-off, it is less invasive than a replacement and lets a business keep operating with minimal disruption. For industrial buildings exposed to chemicals or grease, a PVC roofing membrane is often the better material.
Does California require a cool roof when a commercial roof is replaced?
Usually, yes. Under California’s Title 24 energy code, when more than half of a nonresidential low-slope roof, or more than 2,000 square feet if that is smaller, is replaced, recovered or recoated, the new surface must meet cool roof minimums: an aged solar reflectance of at least 0.63 and thermal emittance of at least 0.75, or an SRI of 75. That applies in every climate zone, including zone 4, which covers San Jose, Sunnyvale and Milpitas. Roof area over unconditioned space, such as many warehouses, does not count.
