Duro-Last® has the highest ENERGY STAR rated roofing system in the commercial roofing industry. Reflectivity is 87.6% in the first year and remains at 86% even after three years, keeping more heat from being absorbed by the building and its machinery. Dark, heat-absorbing roofs are at most 26% solar reflective. Cooler, white roofing systems which reflect over 85% of the sun’s heat can dramatically reduce the energy costs associated with the heating and cooling the building.
Duro-Last® Roofing Systems create a low carbon foot print. It can be installed on top of 90% of existing roofing systems, eliminating the removal of millions of tons of roofing material waste that would end up in our landfills. Duro-Last® is a co-polymer alloy (CPA), which is 100% recyclable at the plant, allowing plastic scraps to be reprocessed and recycled repeatedly. Post-consumer Duro-Last® materials can be recycled and reused in a variety of ways including walkway pads on roofs and around ice rinks, liners for landfills, carpeting, flooring, speed bumps, and asphalt road patching material.
Duro-Last Roofing, Inc. is a member of the U.S. Green Building Council which created Leadership in Energy and Environmental Design (LEED)-a rating system. LEED certified contractors, developers and building owners use environmentally friendly products and designs. They are also members of the Green Globe.
A Duro-Last® Roofing System is cost competitive with all other commercial roofing systems. It is important to note from the cost comparison that the majority of the cost comes from high-quality materials, not the labor. Lesser quality (lower material cost) roofing systems often come with higher roofing installation (labor) costs.
Statistically, with 50% of roof failure caused by poor installation (see graph), paying excessively for a roofing installation (labor costs) is typically money not well spent. Duro-Last® Roofing Systems have stringent quality-control standards. Building the roofing system with 85% of the seams specially made at the factory, significantly reduces the labor investment as well as potential failures created on the project site.
Duro-Last® claims the best warranty in the roofing industry: “15 Year No Dollar Limit”.This warranty is transferable and covers labor, materials, consequential damage, and “ponding” water. The “72-hour underwater warranty limitation”, common in the roofing industry, does not apply. Duro-Last® has no underwater time limitation in their extensive warranty.
No one stands behind their product line like we do. Four Seasons offers a number of Duro-Last warranties that demonstrate our trust in the product – you can choose a 15 year No Dollar Limit (NDL) repair and replacement warranty that covers all consequential damages from a roof leak caused by material or installation. This covers traditional repairs, but also damages to computers, furniture, inventory, and more.
When we say Duro-Last is the best, we are fully ready to stand behind that statement. Connect with us today to optimize your coverage.
