Gorilla Guard™ high performance underlayment for steep slope roof applications. Made to order for the true professional. Contractors across the country told us what they wanted in a high quality underlayment. We utilized new technology to create an underlayment with high performance features that out-performs typical organic felt by adding glass fibers. You´ll save time – and labor costs – by using the right product the first time. |
A specification grade felt used as a waterproof barrier between the roof deck and the shingles. Gorilla Guard is glass reinforced, providing superior stability over standard #15 or #30 organic felt.
