Selecting Superior Roof Underlayment: Synthetic vs. Felt

Introduction to Roof Underlayment

Roof underlayment is a critical component in any roofing system, offering an additional layer of protection against the elements. Positioned directly on the plywood or OSB deck beneath the shingles, it plays a pivotal role in safeguarding your home from water intrusion, ice, and snow. The choice between synthetic and felt underlayment is crucial, as each type offers distinct advantages and limitations.



The Significance of Roof Underlayment

Underlayment not only enhances weather resistance but also adds insulation, seals around flashings, provides a smoother surface for shingle installation, and serves as a sound barrier. Its importance cannot be overstated, as it prevents potential issues like leaks, rot, mold, and mildew.


Felt Underlayment: A Closer Look

Traditionally used in many homes, asphalt-saturated felt underlayment is known for its affordability and accessibility. However, it has its drawbacks, such as susceptibility to tearing, water absorption, and wrinkling, which can complicate shingle installation. Its thickness and weight also present challenges during handling and installation.


Advantages of Felt Underlayment

  • Cost-effective compared to synthetic options

  • Water-resistant

  • Widely available


Limitations of Felt Underlayment

  • Prone to tearing and water absorption

  • Can wrinkle, complicating shingle installation

  • Less durable and weather-resistant


Synthetic Underlayment: Advancing Roof Protection

Synthetic underlayment, crafted from durable polymers, offers enhanced longevity and weather protection. Its lightweight nature facilitates easier handling and installation, with larger rolls providing more comprehensive coverage with fewer seams.


Benefits of Synthetic Underlayment

  • Superior durability and ease of handling

  • Resistant to water, mold, and mildew

  • Provides better protection to the roof deck


Considerations for Synthetic Underlayment

  • Higher initial cost, offset by long-term benefits and protection
