The Customer knows Best !

“The tree men and insurance adjuster couldn’t believe that such a large branch falling on the roof only broke 3 shingles. I’m so glad I went with CeDUR Shakes in 1998. Since then we have had 4 hail storms in Lakewood, CO that all my neighbors had to replace their roofs. My roof is still perfect. Thanks again.”


To match the most true and realistic wood appearance, CeDUR shakes are molded from natural cedar shakes. Our state-of-the art Polyurethane manufacturing process allows us to create incredibly authentic and realistic roofing shakes with unique grain patterns and genuine wood tones and hues. Our thick 3/4 inch butt end provides deep beautiful shadow lines and stunning curb appeal. This adds a beautiful natural looking authentic appearance paired with unmatched durability and superior value.

CeDUR is extremely lightweight at just 170 pounds per square (1 square=100 square ft). CeDUR shakes are lighter than wood, composite roofing materials, synthetic roofing materials, slate, tile, clay tile, recycled rubber and plastic material. CeDUR is a solid roofing material throughout without a “cavity back” or “hollow back” underside. This allows for easy installation for a roofing contractor at the roof’s hips, valley’s, eaves, and rake edges as you can cut our product with a utility knife or skill saw. CeDUR installs just like natural cedar shake and does not require the need for costly structural modification or special reinforcement to the roof structure. CeDUR is Class 4 Impact Rated – UL 2218 impact rating – the highest rating available – and resistant to scratching, scuffing, and high impact. CeDUR is Class A Fire Rated – ASTM E108 – the highest rating available – without the need for a special fire resistant underlayment.
Homeowners that want beautiful aesthetics, lasting performance, stunning curb appeal, long term cost savings, and the most beautiful roof in the neighborhood will love CeDUR. A CeDUR polyurethane roof adds unique beauty to a property without expensive repair or maintenance. Backed by a 50 year warranty CeDUR offers discerning homeowners a highly durable and highly engineered roofing product designed to withstand nature’s worst elements. Trusted by architects, roofing contractors, designers, home builders, property managers, and homeowners across the United States, CeDUR is the long term roofing solution you can trust. 

Class " A " Fire Rated for Your Familes Safety.

Our State-of-the-Art manufacturing process allows us to incorporate a proprietary fire retardant into each CeDUR Shake. In the event of a fire, CeDUR self extinguishes flame spread.

Many roofing products feature a Class A Fire Rating, but you must use an underlayment system to achieve the Class A Fire Rating. The CeDUR product itself is Class A Fire Rated – without the need of a special fire resistant underlayment – with testing certified through the ICC (International Code Council).

Unlike many synthetic roofing products that are composed primarily of Polyethylene, CeDUR is composed of Polyurethane. This allows us to produce a roofing material that is extremely lightweight and durable, with the added benefit of incorporating a fire retardant into our manufacturing process. Natural cedar shakes ignite at 375 degrees, the temperature on our Class A certified burn test reached temperatures as high as 1,400 degrees and we did not ignite.

In the event of a fire, flames spread roof to roof, with embers from the fire being a major cause of traveling fire damage. Using a roofing product that self extinguishes in the event of a fire has the potential to save properties and save lives. In terms of installation, you can lay CeDUR shakes down on top of 30# felt and you have a Class A Fire Rated roofing system.

This fire retardant technology is patented and proprietary to CeDUR.
