Why choose a Duro-Last roof for your facility

Duro-Last manufactures single ply PVC roofing membranes that are custom fabricated to match your roof. Large sections of membrane, curbs, and flashings are pre-welded in the factory so your crew spends less time seaming on the roof and more time delivering a clean, watertight finish.

Custom fabricated for your roof

Duro-Last deck sheets are measured and cut for your building, and up to 85% of seams can be welded in a factory controlled environment. That means fewer field seams, fewer opportunities for leaks, and a more consistent finished surface.

Durable PVC membrane

The PVC formulation is engineered for long term durability, with strong resistance to UV, chemicals, and ponded water when installed correctly. It is a great fit for busy commercial roofs that see regular foot traffic and rooftop equipment.

Energy efficient white roof options

White Duro-Last membranes offer high reflectivity, which can help reduce heat absorption and cooling demand during peak summer months. Many building owners pair a Duro-Last roof with insulation upgrades for better overall energy performance.

Strong warranty protection

Duro-Last is known for comprehensive No Dollar Limit warranty options that can cover material and labor on qualifying projects. Certain warranties also address consequential damage and do not exclude ponding water, which adds extra peace of mind.

Our Duro-Last roof installation process

Every Duro-Last roof project starts with a detailed inspection and measurements. We partner with Duro-Last to have your membrane sheets and accessories fabricated for your specific roof so installation is efficient and consistent.

Roof inspection and assessment. We document the current system, insulation, drainage, and any recurring leak areas.
Design and specification. We work with Duro-Last technical resources to select the membrane thickness, fastening pattern, and details appropriate for your building.
Custom fabrication. Roof layouts, curbs, and edge details are sent for fabrication so large sections arrive ready to install with most seams already welded.
Installation and quality check. Our crew installs the system, completes remaining field welding, and performs a final inspection based on manufacturer standards.
Warranty and ongoing support. Once the project is complete, your Duro-Last warranty is issued for the system that was installed, and our team remains available for inspections and service.

Duro-Last roof warranty overview

On select installations, Duro-Last also offers longer term warranty options that can extend up to 25 or 30 years, subject to membrane type, installation details, and certification level of the contractor.

Frequently asked questions about Duro-Last roofs

How long does a Duro-Last roof typically last?

Service life depends on membrane thickness, roof design, installation quality, and maintenance, but many Duro-Last roofs are designed for multi decade performance. Warranty options often start at fifteen years and can extend longer on certain systems, which gives a good indication of the expected lifespan.

Is a Duro-Last roof only for new construction?

No. A Duro-Last roof can be used on both new construction and re-roof projects. It can often be installed as a recover over an existing low-slope roof or as a retrofit over a metal roof, as long as the existing system meets the manufacturer requirements.

How does a Duro-Last roof compare to TPO or EPDM?

All three are single ply membranes, but Duro-Last PVC stands out for its custom fabrication model, strong chemical resistance, and reflective white options. In many cases the choice comes down to building use, rooftop conditions, and owner priorities. We will lay out the pros and cons so you can compare options.

What maintenance does a Duro-Last roof need?

A Duro-Last roof system is low maintenance, but every commercial roof still needs regular inspections, debris removal, and attention around drains and penetrations. We recommend at least one inspection per year and after major storms to protect your investment and maintain warranty coverage.
