Choosing the Best Roof Underlayment for Asphalt Shingles


As a professional contractor with years of experience in Rockland County and Westchester County, I've seen firsthand the importance of selecting the right roof underlayment for asphalt shingles. This often-overlooked component plays a crucial role in the overall durability and performance of your roof. Let's dive into what makes the best roof underlayment and why it's essential for your home.




Roof underlayment is a protective layer installed between your roof deck and the asphalt shingles. It acts as a barrier against water, ice, and other elements, providing an extra line of defense for your home. The most common types of underlayment are:


  • Asphalt-Saturated Felt: Traditional and cost-effective, but heavier and less durable compared to modern alternatives.

  • Synthetic Underlayment: Lightweight, durable, and resistant to tearing, making it a popular choice among contractors.

  • Rubberized Asphalt: Offers superior water resistance and often includes adhesive backing for easier installation.



Factors to Consider

When choosing the best underlayment for your roof, consider the following:


  1. Climate: In Rockland County and Westchester County, we experience a range of weather conditions, from heavy rains to snowstorms. Synthetic underlayment is typically a great choice due to its resilience and durability.

  2. Budget: While synthetic and rubberized asphalt underlayment may be more expensive upfront, their long-term benefits often outweigh the initial costs.

  3. Roof Slope: For steeper roofs, a lighter synthetic underlayment can be easier to work with and provides excellent protection.



In conclusion, investing in high-quality roof underlayment is a smart decision that can significantly extend the life of your roof. If you're considering a roof replacement or repair, consult with a trusted contractor to determine the best underlayment option for your specific needs. Your roof is one of the most critical components of your home, and it deserves the best protection available.
