Commercial

We have the experience and crews to install commercial flat roofs for warehouses, restaurants, apartments, condominiums, and retail establishments, etc. Proper drainage is the number one cause of premature roof failure and must be addressed prior to new roof installations. Our professional inspectors will provide building owners with a comprehensive evaluation and estimate for long-term roof solutions. We proudly sell and install Duro-Last Roof Systems.

Duro-Last®: The “World’s Best Roof®”

  The Duro-Last® prefabricated single-ply roofing system is ideal for virtually any commercial or industrial, flat or low-sloped application. The highly-reflective white membrane delivers real energy cost savings for building owners and managers. Extremely durable and easily installed without disruption to daily operations, the Duro-Last roofing system is also leak-proof, resistant to high winds, and virtually maintenance-free. The Duro-Last single-ply roofing system is ideal for any flat or low-sloped application. Since 1978, over a billion square feet of Duro-Last membrane have been installed on buildings of all types. 


The Duro-Last roofing system is:

Precision fabricated. Every Duro-Last roof is manufactured to exact size in our controlled factory environment. This eliminates up to 85% of rooftop installation seaming and ensures an excellent fit, delivering worry-free, leak-proof, long-term protection.

Energy-efficient. The Duro-Last white membrane has the highest retained reflectivity of any single-ply membrane rated by the EPA’s ENERGY STAR® Roof Products Program, saving significant energy and money for facilities of all types throughout North America.

Durable. The Duro-Last roofing system is resistant to fire, chemicals, grease, high winds and punctures, and easily accommodates wide temperature extremes. 

Installed by Authorized Contractors. Duro-Last only sells to Authorized Contractors like One Stop, meaning not just everyone can install it!  

Installed with little disruption. Installation is quiet and safe, without loud machinery, hazardous materials, noxious fumes, hot tar or mess. A new Duro-Last roof often can be installed over an existing roof without an expensive tear-off. 

Backed by the industry’s best warranties. Duro-Last’s standard, comprehensive 15-year full warranty is transferable, has no exclusions for ponding water, and provides coverage against consequential damages that result from defects in the Duro-Last material and/or installation. Duro-Last also has 20-year warranties available.

Our Process

  1. Once we receive an estimate request, an experienced estimator will schedule an appointment to come out and take a look at the roof.
  2.  We will provide a detailed estimate along with repair options. 
  3. After we receive a signed contract, we will work together to schedule the new roof or repair.
  4. A job manager will visit the business often to verify that the flat roof installation process is being done correctly.
  5. A final invoice is sent to the business and the insurance company.
