PV (Photovoltaic) Systems

Much of the commercial building industry is looking to rooftops as a source for electricity generation. This demand has sparked incredible growth in the installation of rooftop photovoltaic (PV) systems. A double-digit PV sales trend in recent years is expected to continue into the foreseeable future.

Informed building owners and managers who are evaluating an investment in PV are also considering installing a new roofing system underneath.

Duro-Last® Cool Zone®: The Solar-Ready Roofing System

The Duro-Last roof system is ideal for any commercial rooftop solar application. It’s precision-fabricated to fit each building, and delivered to the job site with up to 85% of membrane seaming completed in our factory. Also, custom fabricated stacks and curb flashings eliminate nearly 100% of rooftop labor from the most critical roof areas – transitions and changes of plane.

Duro-Last’s prefabrication approach means that you can be confident of a long-term, watertight fit – a major consideration when the membrane will be covered with solar panels.

Regardless of the specific PV technology you are considering, Duro-Last is the ideal membrane to install on your roof deck first. It’s “solar ready” – engineered to accommodate all photovoltaic systems available on the market today.

Duro-Last’s membrane for PV applications boasts 28 mils of thickness above the membrane’s scrim, and a 30-year track record of quality. These facts combine to provide performance that matches and even exceeds the expected life expectancy of most rooftop solar systems.

With the industry’s highest membrane reflectivity, you may achieve a quicker pay back of your PV system investment due to energy savings from high reflectivity in roof areas exposed to the sun. Installing high R-value expanded polystyrene insulation under the membrane can provide a payback that’s even faster.

Exclusive patents and prefabrication combine to provide dependable watertight performance necessary under your solar equipment. Fully inspected and tested the membrane right choice under your system.

Properly Engineered

If your current roof is leaking, and you’re not yet in the market for PV, the formulation of the Duro-Last membrane allows for the application of solar equipment years down the road. It remains weldable and easily accommodates any new penetrations that may be required – whether for solar systems or other rooftop equipment.

Installed by certified installers, hand inspected by the manufacturer, you are covered by the most comprehensive warranty in the industry. By installing a Duro-Last Roof you are uniquely "Solar Ready."
