Next to shingles, underlayment is one of the most important components in building an optimal roof. Underlayment acts as a weather and water barrier to help protect the seams and joints of the plywood roof deck from moisture while still allowing it to breathe. It also assists in creating a seal around the nails in the roof to prevent leaks.

Today, there are more options for roofing underlayment materials than ever before. From organic to rubberized asphalt underlayments, fiberglass to synthetic roof underlayments, contractors, builders, and homeowners have a world of choices when it comes to selecting their type of underlayment. Fortunately, RWC Building Products makes it fast, affordable, and easy to find exactly the right product for your needs.

Below are some of the leading brands of underlayment we carry.
