Unveiling the Best Roof Underlayment: Synthetic vs. Felt

Selecting the right underlayment for your roof is a crucial step in ensuring longevity, durability, and peace of mind for homeowners. It is important to choose the right underlayment for specific roofing materials, such as asphalt shingles. At A&M Roofing, we're deeply familiar with the various options available in the market.


Today, we aim to provide insights into two primary contenders: Synthetic and Felt Roof Underlayment. As leading Springfield roofing contractors, we've installed countless roofs and have firsthand experience with both types.


What is Roofing Underlayment?


Before diving into the differences, it's essential to understand the role of roof underlayment. Acting as a protective barrier, the underlayment goes directly onto the roof deck, safeguarding it against moisture, heat, and other external elements before the shingles are placed on top. It is also important to consider the top roof layer material when choosing the right underlayment, as different materials like asphalt and metal roofs require specific types of underlayment for optimal performance.

Synthetic Roofing Underlayment: Benefits and Drawbacks


  • Durability and Strength: One of the top benefits of synthetic underlayment is its durability. It’s less likely to tear and can withstand harsh weather conditions, making it an ideal choice for a roof installation in Springfield, VA. Compared to traditional roofing materials, synthetic underlayment offers superior durability and ease of installation.

  • Lightweight: Being lighter than its felt counterpart, synthetic underlayment is often easier to install and handle, ensuring a faster installation process.

  • Water Resistance: High-quality synthetic options offer excellent water resistance, reducing the chances of mold and rot.

  • Cost: While synthetic underlayment may come with a steeper initial cost, its long-lasting nature often makes it a cost-effective solution in the long run.

  • UV Exposure: Some synthetic underlayments can be exposed to UV rays for extended periods without deteriorating.


However, like all materials, synthetic underlayment has drawbacks. It can be slippery, especially when wet, which might pose challenges during installation.


Felt Roofing Underlayment: Advantages and Limitations


  • Natural Material: Traditionally, felt underlayment is made from natural materials like wood cellulose, making it an eco-friendly option.

  • Affordability: Felt tends to be more affordable up front, making it a go-to for many homeowners.

  • Flexibility: Due to its organic nature, felt underlayment can mold to the roof deck, providing a snug fit. Rubberized asphalt underlayment, made from rubber polymers and asphalt, offers a strong waterproof seal, flexibility, and sound absorption, making it ideal for regions with extreme temperature changes. 

  • Protection: It offers adequate protection against resin bleed-through, which can occur with some wooden decks.


On the flip side, felt underlayment can absorb moisture, making it susceptible to wrinkling if exposed to wet conditions for prolonged periods.


Making The Right Choice for Your Home


Both synthetic and felt roofing underlayments have their merits. When choosing a roofing system, it is essential to consider its importance in protecting against moisture, improving energy efficiency, and supporting different types of roofing materials. Additionally, the type of roof underlayment plays a crucial role in shielding against water damage and providing insulation. Your choice will hinge on your budget, your home's specific needs, and the advice of trusted Springfield roofing contractors.

Conclusion


Your roof is your home's first line of defense against external elements. Choosing the right underlayment is essential for the longevity of your roof and the safety of your home. Both synthetic and felt roofing underlayments come with their set of advantages and limitations.


Synthetic and rubberized underlayments offer a more durable alternative to traditional felt underlayments. Rubberized underlayment is known for its durability, self-adhering properties, and effectiveness in preventing leaks from weather events. It is suitable for different climates, including colder climates with snow and ice, as well as extremely high temperatures.
