Roll Roofing


USA: Roll Roofing Manufacturers





Roll roofing is the common term for asphalt saturated felt roofing, supplied in rolls. Roll roofing should be stored in a dry location, and should always be stored with the rolls on end. If it is stored on its side the rolls will flatten out and crack. It is not good practice to install asphalt roofing at temperatures below 45 degrees. If the roll roofing has been stored at temperatures below 45 degrees, the roll should be warmed to avoid cracking. It should then be cut into lengths of around 18 feet, which should be stacked flat in a pile to flatten out.  


To provide a durable roof, it is recommended to use two layers of roofing, with the nails concealed. The roofing should be applied over clean, dry plywood, with the sheets running parallel to the eaves. All selvage laps and end laps should be sealed with roofing cement. This type of roofing can be applied to any roof that has a slope of at least 1 in 12.
