Understanding the Different Types of Roofing Underlayment: A Comprehensive Guide May 06, 2025

Choosing the right roofing underlayment is crucial for the longevity and effectiveness of your roof—a vital part of your home's protection. Underlayment serves as a secondary barrier, guarding against water and moisture infiltration. At RFK Contracting, we understand that making informed decisions about roofing can be daunting. That's why we're here to simplify the world of roofing underlayment for you.Roofing underlayments come mainly in three types: asphalt-saturated felt, synthetic underlayments, and rubberized asphalt underlayments. Each type offers distinct advantages, and understanding these differences can help you make the best choice for your roofing project.Asphalt-saturated felt is the traditional choice for underlayment material and has been used extensively over the years. It's made by saturating paper or fiberglass mat with asphalt to create a water-resistant barrier. This type is generally more affordable and readily available, making it a popular option among homeowners. However, it is worth noting that it can be prone to tearing and may not perform as effectively under prolonged moisture exposure. If you're in an area with severe weather, you might want to consider other options that offer additional durability.The next type, synthetic underlayment, has gained popularity due to its robust performance and lightweight nature. Unlike felt, synthetic underlayments are made from polymers, which gives them increased tear resistance and long-term durability. This type is less likely to break down over time and can withstand exposure to UV rays. This durability comes at a slightly higher cost, but many find the investment worthwhile. If you're aiming for a sturdy roof that will stand the test of time, synthetic underlayment is an excellent choice.Lastly, there's the rubberized asphalt underlayment. Known for its superior waterproofing capabilities, this type is ideal for roofs prone to leaks, such as those in heavy rainfall regions. Rubberized asphalt underlayment often comes with a self-adhesive back, making it easy to install and providing excellent sealing power around fasteners. Although it is the most expensive option among the three, its outstanding moisture repelling properties might save you money on repairs in the long run.When deciding on the best roofing underlayment, consider your climate, budget, and the specific needs of your home. Asphalt-saturated felt might be suitable for tight budgets and moderate climates. In contrast, synthetic materials offer longevity and strength and are well-suited to most environments. For those looking to fortify against water damage, especially in areas with heavy precipitation, rubberized asphalt can be your roofing ally.RFK Contracting is committed to guiding you through every step of your roofing journey.
