Synthetic roofing underlayment is the industry standard. It outlasts felt. It protects better. It installs faster. This is your guide to the best in the business. Learn the specs. See the benefits. Get back to the job site.
The Death of Asphalt Felt
Traditional felt is a relic. It is made of paper and oil. It absorbs water. It bubbles under your shingles. One gust of wind and it rips off the deck.
Look at the facts. Asphalt felt is four times heavier than synthetic. It covers less area per roll. You spend more time on the ladder. You spend more time hauling trash.
Choose Epilay. It is 100% synthetic. It is 25 times stronger than #15 felt. It does not absorb moisture. It stays flat. Forever.
