Contractors that choose Barricade® Underlayments, over asphalt-saturated felt roof underlayments, can avoid many of the problems of felt that lead to early underlayment replacement and damage to the roof deck and the structure. Barricade Underlayments are quicker to install and have greater strength and UV resistance than felt underlayment.
Roofing underlayment is the product installed under all the roofing materials and directly on a roof deck. The underlayment provides a secondary weather barrier against exterior elements like wind-driven rain and snow. The shingles are the primary weather barrier.
Contractors have used asphalt-saturated felt underlayment for decades. A blend of cellulose, polyester, bitumen, and asphalt is used to make felt underlayment. Felt is available in two thicknesses: fifteen-pound and thirty-pound. Fifteen-pound felt underlayment has a perm rating of about five, although this number can rise in high-humidity conditions. Thirty-pound felt is thicker and stiffer than fifteen-pound, so thirty-pound is more resistant to damage during installation and can protect the roof longer if exposed to outside elements like wind, rain, or snow.
Contractors and building owners like asphalt-saturated felt underlayment because it is a low-cost product that is easy to install. However, there are problems with asphalt-saturated felt underlayment that can cause it to fail.
