Choosing the Best Roofing Underlayment

Your residential roof installation consists of different materials and components working together to keep your home safe and secure. While shingles make up a large part of the exterior in terms of beauty and performance, there’s another layer right beneath the surface that provides additional protection.

Understanding Your Underlayment

The underlayment is a material that’s rarely seen in a well-built roofing system. It’s right between the shingles or surface materials and the roof deck. The underlayment forms an additional layer of protection on your roof that prevents water and moisture from infiltrating and damaging the inner structure. It essentially keeps the elements from causing mold, mildew, rot and internal damage to the wooden components. It even provides thermal insulation during the winter season and retains indoor heat while keeping out the cold weather.

Popular Underlayment Options

It’s recommended that the underlayment be replaced along with the rest of your roof once it reaches the end of its serviceable life. Here are some of the most popular underlayment options on the market:

  • Rubberized Asphalt – This popular underlayment is one of the pricier materials on the market, but it’s worth the investment if you want exceptional weather protection and leak prevention for your roof. It’s made of rubber polymers and asphalt which give it a familiar and rubberlike form. One side has adhesives so it can be applied directly to the deck.
  • Felt – This material is less expensive than rubberized asphalt and has been a longtime staple in the roofing industry. It’s mostly made of organic felt saturated in asphalt to make it water-resistant. This also makes the material highly durable and reliable. It may also contain additional materials such as fiberglass reinforcement to increase strength and longevity, but this depends on the manufacturer.
  • Synthetic – Most non-bitumen synthetics cost more than traditional felt, but they offer more benefits and features. They’re also entirely waterproof and insulated so even ice won’t easily penetrate the surface. This makes synthetics a popular choice for many homeowners, and keeps your attic free from excess moisture as it’s more breathable.
