Duro-Last is Ideal for Any Flat / Low-Slope Application

Secure Watertight Installation

Every Duro-Last roofing system is prefabricated in a controlled factory environment to rooftop specifications. This eliminates up to 85% of rooftop installation seaming and ensures an excellent fit, delivering worry-free, leak-proof, long-term protection.

The Duro-Last system is resistant to fire, chemicals, grease, high winds and punctures, and easily accommodates wide temperature extremes.

A Duro-Last installation by Royalty is quiet, fast, and safe, without loud machinery, hazardous materials, noxious fumes, hot tar, or mess. A new Duro-Last roof can often be installed over an existing roof without an expensive tear-off.

The Duro-Last roofing warranty is the best in the industry. It protects commercial and industrial buildings with a comprehensive 15-year No Dollar Limit (NDL) warranty that is transferable, has no exclusions for ponding water, and provides coverage against consequential damages that result from defects in the Duro-Last material and/or installation workmanship. Duro-Last also has 20-year warranties available. In addition, every Royalty installation is backed by our own 10-year Workmanship Warranty.
