CLP™ Roofing Systems



You want a cost-effective roof replacement option, but want it to be worry-free, too. Simon Roofing is the world’s largest manufacturer of CLP™ Roofing Systems which are technologically advanced rolls for roof replacements that provide superior weathering characteristics and a roof surface that offers lifelong sustainability.

CLP™ Roofing Systems over metal, wood, concrete, and lightweight roof decks meet or exceed requirements in high velocity hurricane and wind zones.

CLP™ Roofing Systems incorporate an innovative manufacturing process that saturates the system at factory-controlled temperatures. This saturated manufacturing process helps to prevent the membrane from separating, bond all system components, and prevent loss of adhesion. Other single-ply systems are laminated at extremely high temperatures, which could result in the loss of vital polymers burning off in the process.

CLP™ Roofing Systems also offer cross-linked polymers with the reinforcement scrim used in the membrane, which has proven to improve both its strength and weather resistance. Most importantly, it utilizes Wite Brite™ technology as the waterproofing membrane. With over 20 years of proven performance, Wite Brite™ coatings have endured the test of time. Now with state-of-the-art technology allowing for this material to be applied in a factory-controlled temperature environment, CLP™ Roofing Systems are the best of both worlds in the science of roofing.


  • More Waterproofing. A technologically advanced single ply roll within the CLP™ Roofing Systems undergoes a saturated manufacturing process to bond all system components together as one. This saturated makeup offers waterproof protection throughout the system and above the scrim; not just a thin layer on the top and bottom of the reinforcement scrim like laminated single-ply systems provide. Lamination and saturation do not produce membranes with equal properties – learn more.
  • Added Redundancy. Multiple, redundant layers, combined with a technologically advanced roll, provide added strength and reliability. An optional field-applied finish coat ensures a monolithic, watertight membrane that perfectly conforms to the unique contours of the existing surface being re-roofed.
  • Greater Strength. CLP™ Roofing Systems have tensile strength that’s significantly greater than common single-ply roof systems. Therefore, when there are extreme temperature changes during normal seasonal periods, it won’t crack under the stress of thermal shock like some single-ply membranes could. They also have greater puncture resistance and breaking strength, meaning they’re more resistant to punctures from falling objects and cracking from normal foot traffic and/or weather elements.
  • Better Weathering. CLP™ Roofing Systems have substantially more waterproofing within and above the reinforcement sheet, which is where it’s most needed for better weathering and slower aging. The cross-linked polymer in CLP’s formulation is superior in UV resistance, which improves the rate of oxidation. The compound is also fortified with inert and organic chemicals that enhance reflectivity and emissivity to further improve weathering.
  • Less Erosion. The greater the mass/weight of a roofing system, the slower the effects of erosion. When compared to most single-ply systems, CLP Roof Systems weigh more and erode less.
  • Stronger Warranty. CLP™ Roofing Systems come with a manufacturers labor, workmanship, and materials warranty that is one of the strongest warranties of its kind. Plus, Simon Roofing is the manufacturer and installer, so warranty calls come with no finger-pointing and response times within 24 hours.
  • More Sustainable. The useful life of CLP™ Roofing Systems can be easily and economically extended at least 20 years after their warranty period. These systems are fully compatible for future restorations, which reduces tear offs and the use of landfills, as well as lowers their life cycle cost.

CLP™ Roofing Systems – the roof system you may never have to replace again!
