why choosesustainability?

People are thinking more and more about their carbon footprint and how they can not only reduce it but also make their businesses run more efficiently.

A white highly reflective roof system can reduce urban heat. This makes it easier to keep the interior of their building cool which lowers energy cost.

We have experience! We have been installing sustainable roofing systems since our beginning due to their longevity and performance.

How We Do It


    Rooftop solar systems that are designed for commercial buildings with flat roofs can be rack mounted (with ballasted or attached racks) or adhered directly to the roof surface. While an adhered solar system will involve fewer penetrations that require flashing, it also restricts access to much of the roof. A rack-mounted system can allow access to the roof, but very secure flashing methods must be used to avoid compromising roof integrity.

  • WHY

    Duro-Last Roofing Systems are particularly effective for rack-mounted rooftop solar systems. It is precision-fabricated to fit each building and delivered to the job site with up to 85% of membrane seaming completed in their factory. Custom prefabricated flashings for roof-penetrating support structures eliminate most rooftop labor from these critical areas. Pre-made rack flashing can mean faster roofing system installation as well!


    Americans spend about $40 billion annually to air condition buildings. That’s one-sixth of all electricity generated in this country. White, reflective roofing can help reduce the amount of air conditioning needed in buildings, and can reduce peak cooling demand by 10-15% and can provide 20% air conditioning cooling savings for the building owner. This could possibly save 30-40 mega watts per year in california alone.


    Garden Roofing Systems offers a diverse line of traditional and modular Roof Garden systems, as well as a wide variety of vegetation options to fit each project’s individual requirements and design aesthetics. Roof Gardens offer a variety of benefits, including stormwater management, increased usable roof space, improved aesthetics, reduced urban heat island effect, and extended roof service life.


    Many companies claim to prioritize recycling, but at Duro-Last it is a focus at every step of the manufacturing process through the entire lifecycle of our products. During manufacturing, edge trim and scrap is kept clean and recycled back into production. This allows Duro-Last to reduce waste and recycle virtually all of its manufacturing waste. In our manufacturing facilities and corporate offices, our goal is to eliminate landfill waste.


    By reflecting up to 88% of the sun’s energy, white Duro-Last membranes can greatly reduce energy costs. This makes Duro-Last the ideal cool roof option. With a total solar emittance of up to 95%, the ENERGY STAR® qualified Duro-Last membrane also releases energy and heat efficiently.
