Your Authorized Duro-Last® Contractor in Lexington

Royalty Roofing is proud to be a Platinum Level Contractor for Duro-Last Roofing. The prefabricated Duro-Last single-ply roofing system is ideal for any flat or low-sloped, new or retrofit application. Since 1978, over two billion square feet of Duro-Last roofing membrane have been installed on buildings of all types throughout North America.


We are headquartered in Seymour, Indiana, and install Duro-Last roof systems for roofing customers who have single locations in Lexington as well as those with multiple facilities throughout the continental United States. In our history, we have installed more than 22 million square feet of Duro-Last material.

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 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.
