Five Reasons to Consider a Duro-Last Roofing System

A Duro-Last roofing system is a strong, reinforced thermoplastic single-ply membrane that is perfect for commercial and industrial buildings with flat or low-sloped roofs.

The membrane is “precision fabricated” to the building’s specifications in a controlled factory environment, including all accessories and edge details. Then most of your roofing system components are carefully assembled in our factory and shipped to the building site for final installation.

What does this mean for building owners?

1. A faster, less disruptive installation – less mess, noise, odor, and risk to sensitive equipment.
2. A durable, long-lasting roof – resistant to fire, chemicals, grease, high winds, punctures, and temperature extremes.
3. Fewer problems down the road – leak-proof and virtually maintenance-free.
4. Lower energy costs – among the most energy-efficient roofs available today.
5. Guaranteed quality – backed by the industry’s best warranties.

Let’s look at each of these Duro-Last benefits and see how they impact the roof’s life-cycle costs.

1 – A faster, less disruptive installation When access to a building is disrupted, it costs the owner time and money. That’s where prefabrication really sets Duro-Last apart. Because our roofing system is precision fabricated in a factory-controlled environment, a Duro-Last roof goes on faster with less waste. Installation is quiet and safe, with no loud machinery or noxious fumes to disrupt building occupants. And oftentimes, a new Duro-Last roof can be installed over an existing roof.

That eliminates the risk of sensitive equipment or data being damaged by debris or exposure to weather, and it allows you to maintain business as usual. It may also avoid the added costs of tearing off and disposing the old roof.

Precision fabrication begins when a Duro-Last contractor or representative measures the area to be covered by your roof, taking into account all dimensions, curbs, stacks, and other penetrations. The measurements are then sent to our Duro-Last facility, where up to 85% of membrane seaming is completed and all stacks and flashings are custom fabricated – before the roof is shipped to the site for installation.

2 – A durable, long-lasting roof A Duro-Last roof is resistant to fire, chemicals, grease, high winds, and punctures, and it easily accommodates wide temperature extremes. Once installed, it is virtually maintenance-free, unlike other roof materials that may require regular patching or other repairs. The proof is on the roof: over 1½ billion square feet of Duro-Last roofing membrane have been installed throughout the U.S. since 1978, and the vast majority of those roofs are still in service. Many Duro-Last roofs have outlasted their owners’ expectations by 5 years, 10 years or more.

3 – Fewer problems down the road The weakest point of any roof is where two or more pieces join together, and this is another distinct benefit of Duro-Last’s precision fabrication. Up to 85% of the seams in a Duro-Last roof are completed in a quality-controlled factory environment, assuring a better seal. In addition, stacks and curb flashings are custom fabricated in our factory. This eliminates nearly 100% of rooftop labor from the most critical and problematic installation points: transitions and changes in plane. The few remaining seams are completed on-site by authorized Duro-Last contractors and inspected by a Duro-Last technical representative before a warranty is issued. The benefits for you are fewer leaks, problems, and repair bills over the life of your roof.

4 – Lower energy costs 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. That means you can save money on cooling costs with a Duro-Last roof.

How much you’ll save depends on your location and current energy rates as well as other factors specific to your building. For a detailed analysis of your potential energy savings, go to www.roofcalc.com. In some areas of the country, special rebates, loans or incentives are in place to encourage building owners to reduce energy costs. Check with your utility supplier or governing body about programs that may be available in your area.

5 – Guaranteed quality Even the best roofing materials are only as good as the quality of the installation. That’s why all Duro-Last precision-fabricated roofs are professionally installed by authorized contractors, who can call on the expertise of Duro-Last designers, engineers, and quality control technicians at any time. Duro-Last is so confident in the durability of our roofing systems that we protect commercial and industrial installations with the best warranties in the industry.
