USA: Corrugated Roofing: Corrugated Roof Manufacturers
ABOUT CORRUGATED ROOFS AND ROOFING
Corrugated roofing is supplied for both residential and industrial applications. It is made from a wide variety of materials including asphalt, polycarbonate, and various metals including steel and aluminum. For residential applications corrugated roofing may be applied over the existing roof, without removing the old roof covering. This reduces costs by avoiding the need to remove and dispose of the old roof material. The advantages of asphalt and polycarbonate corrugated roofing are that they are lightweight, easy to handle, and do not corrode. Steel corrugated roofing is more robust, and better suited to industrial applications. To resist corrosion it requires special treatment. This can consist of up to four coatings: galvanizing, chromate treatment, primer, and final hard finish.
