Commercial Roof Replacement for Flat Roofs, Metal Roofs & Reroof Projects

The timeline for a commercial reroof depends on several factors, including the size and complexity of your building, roof type, deck condition, weather, and whether the project is phased for occupied operations. For example, a 10,000 sq. ft. building might take anywhere from several days to two weeks, especially if daily dry-in procedures are required to keep your operations running safely. We provide a detailed schedule and phasing plan with every proposal, so you always know what to expect.

A “tear-off” means removing all existing roofing materials down to the roof deck, allowing us to address hidden issues like trapped moisture, damaged insulation, or deteriorated decking. This is often the best choice for long-term performance and warranty eligibility.

A “recover” (or overlay) involves installing a new roofing system over an existing one, provided the current roof is dry, stable, and local code allows it. This can save time and money but isn’t suitable if there are underlying moisture or structural issues. We’ll evaluate your roof and explain which option is safest and most cost-effective for your property.

An “NDL” (No Dollar Limit) warranty is a premium manufacturer-backed guarantee that covers eligible repair or replacement costs—both materials and labor—up to the full value required, with no preset financial cap. NDL warranties typically last 20–30 years and require the system be installed by certified contractors according to strict manufacturer guidelines. This provides property owners with maximum peace of mind and long-term protection, as long as maintenance requirements are followed.

Yes, we handle the entire permitting and documentation process for your reroof project. This includes preparing and submitting all necessary paperwork for city or county approval, as well as ensuring your new system meets California Title 24 Building Energy Efficiency Standards. We provide detailed insulation, cool roof, and assembly documentation, and coordinate with inspectors as needed. Our team keeps you informed at every step so there are no surprises during your reroof.

We specialize in a range of commercial flat roof systems, including TPO, PVC, modified bitumen, and advanced coated assemblies. The best choice for your building depends on factors like drainage, rooftop traffic, interior use, energy efficiency goals, and budget. We’ll explain the pros and cons of each system and recommend the optimal solution for your property, ensuring it meets both performance and warranty requirements.

Absolutely. We have extensive experience working on occupied buildings, including retail centers, warehouses, and multifamily properties. Our occupied-building protocol prioritizes safety, noise control, and daily dry-in procedures to minimize disruption. We coordinate with your team to schedule loud or disruptive work outside of peak business hours, maintain clear safety perimeters, and ensure debris is managed daily. This way, your business or tenants can continue operating safely throughout the project.
