Tilcor's CF Shake has been specifically designed for the North American market to resemble the rustic charm of traditional Shake but without the inherent ongoing issues that many home owners face. Its innovative fully "Concealed Fastening" system is truly a world's first. The Tilcor CF Shake textured-finish tile features the wood-grain appearance of traditional shake. Its deep-ribbed profile is designed to enhance the shadow lines and create visual contrast. Unlike other systems, which leave gaps and screws exposed to the elements, our unique CF Shake protects all fastening elements making roofs more reliable, watertight and durable than ever before.
