High Performance Synthetic Roofing Products

CeDUR Synthetic Roofing Products are designed and engineered to combat Mother Nature’s harsh elements while providing the most authentic wood shake look. Learn more about how our polyurethane based synthetic roofing products combat the elements of heat, moisture, wind, hail, and snow.

Authentic Wood Look. Extreme Fire Resistance. Lasting Performance.

For years the roofing industry has been trying to create synthetic composite roofing materials that have the authentic natural wood appearance and are low maintenance, fire rated, impact resistant, and long lasting. Until now, no replacement roofing products have been able to match the authentic wood appearance of hand split natural cedar shakes. Other roofing products simply do not have the depth, texture, dimension, and color variations of a natural cedar shake roof. Even other synthetic roofing products composed primarily of polyethylene can provide an unnatural and shiny appearance. The proprietary polyurethane technology that CeDUR developed provides homeowners and industry professionals with the most natural wood shake looking synthetic roofing product available.

Our state-of-the-art polyurethane manufacturing process allows us to mold each individual CeDUR shake from hand split natural cedar wood shakes. This gives CeDUR unquestionable wood shake beauty while enhancing your home’s curb appeal and property value. CeDUR Synthetic Shakes are light weight (just 170 pounds per square), feature a 3/4” inch butt end, and perfectly replicate the appearance of heavy hand split natural cedar shakes. A CeDUR synthetic roof provides authentic wood depth, dimension, thickness, and texture while meeting and exceeding the roofing industries most stringent testing standards.

  • CeDUR Synthetic Roofing Products are stand-alone Class A Fire Rated (ASTM E108, UL 790). No special fire-resistant underlayment is necessary during installation in order to achieve the Class A Fire Rating. This is the highest industry rating obtainable for fire resistance. In the event of a fire, CeDUR’s proprietary fire-resistant technology will extinguish flame spread and not allow a flame to propagate on the surface of the product.

  • CeDUR Synthetic Roofing Products are Class 4 Impact Rated (UL 2218). This is the highest industry rating obtainable for impact resistance. CeDUR synthetic roofing products have earned classification as Class 4 impact resistant and Class A fire resistant.

  • CeDUR Synthetic Roofing Products are light weight at just 170 pounds per square (1 square = 100 square feet on roof). CeDUR is one of the most light weight roofing products available for purchase. CeDUR’s light weight product composition makes the product easy for roofing contractors to handle and install. CeDUR does not have a cavity back so you can cut and score the product with a utility knife or skill saw. This allows for easy installation on your roofs valleys, eaves, gable, rake, and hips because the CeDUR product can be easily cut and scored using a utility knife to fit into tight or unique spaces on your roof without sacrificing appearance. CeDUR synthetic shakes require no sealing or treatment to cut edges due to their closed cell structure which permits no significant water absorption.

The Best Alternative to Natural Cedar Shakes

We understand that repairing or replacing aged roofs can be difficult and costly. Traditional roofing materials found on aged properties no longer meet modern safety or building codes and natural wood shakes can be a fire risk and high risk liability for insurance companies covering residential dwellings.

CeDUR synthetic roofing shakes are the best alternative to natural cedar shakes and traditional roofing materials. Our synthetic roofing products are designed and engineered to withstand nature’s harsh elements while providing long term beauty and value. CeDUR shakes provide the same appearance of heavy hand split natural cedar shakes and can be installed in straight courses or staggered courses.

Insurance Savings for Homeowners

Insurance companies are more and more cautious of advising homeowners to install or repair their natural cedar shake roof, especially in high fire danger zones due to durability concerns and fire risk associated with wood. Wood shakes and alternative roofing materials are potentially a high risk liability for insurance companies covering residential dwellings.

CeDUR is listed on most major insurance companies premium credits product listing. This includes companies like State Farm Insurance, Chubb Insurance, and American Family Insurance. Homeowners with a CeDUR synthetic roof have the potential to receive insurance policy discounts which can result in significant long term cost savings.

Solid Product Throughout - No Cavity Back

CeDUR is not a hollow back or cavity back roofing product, so on the back side of the product you will not notice a waffle like structure. Instead, CeDUR is a solid product throughout with color through pigmentation, so each individual shake is solid. CeDUR shakes require no sealing or treatment to cut edges due to their closed cell structure which permits no significant water absorption. Just like heavy hand split natural cedar shakes, each CeDUR synthetic shake is 3/4" inch thick at the butt end. This creates incredible roof depth and texture, and makes CeDUR indistinguishable from natural cedar shakes.
