Many existing Indiana properties have what is termed as rolled roofing products on the flat roofing surfaces. Flat roofing is most generally refereed to on slopes less than a 3 /12 pitch. These systems traditionally fail after a short period of time. The reason for most failures is the installation process and products that have been used. The most typical type of products used have been the rolled roofing mineral surface materials. The products have been either placed by nailing them directly to the plywood decking or felt paper and the 3 inch laps are sealed with tar. The tar quickly breaks down and is not a seal for possible standing water. Currently codes nationally do not allow the rolled roofing to be installed under 1/12 pitches.
