Barricade® Roof Underlayments have all of the benefits of both asphalt-saturated felt and synthetic underlayments. However, an added advantage of Barricade® Underlayments is they save time and money because they can be installed quicker than standard 36” wide felt underlayments.
Asphalt felt and synthetic underlayments are products installed under all the roofing materials and directly on a roof deck. The underlayment provides a secondary weather barrier against wind-driven rain and snow. The shingles are the primary weather barrier.
Roofing asphalt-saturated felt is a blend of cellulose, polyester, bitumen, and asphalt, soaked in a waterproofing agent. It comes in two thicknesses: fifteen-pound and thirty-pound. Thirty-pound felt is more thick and stiff 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 rain, wind, hail, and snow. Asphalt-saturated felt underlayments are semi-permeable and typically have a perm rating of five to seven.
Builders and architects have used asphalt-saturated felt underlayment for decades because it is a low-cost material and is easy to install. Importantly, asphalt-saturated felt underlayment is commonly allowed by local building codes.
Most synthetics are spun or woven from either polypropylene or polyethylene. The specific manufacturing process produces synthetic underlayments with different properties such as the thickness, exposure time, and resistance to damage during the installation process, etc. Like asphalt-saturated felt, comparisons between synthetic underlayments are by weight. However, synthetic underlayments utilize grams-per-square-meter (GSM) as their measurement.

1Wicking or capillary action is when a liquid, like water, to flows through a narrow space without the assistance of, or opposition to, external forces like gravity. An example of capillary action is when a liquid moves up straw.
2 Seepage barriers control and mitigate the flow, or seepage, of water through the foundation of a building or home.
