How to Choose the Right Roofing Underlayment

How to Choose the Right Roofing Underlayment

Roofing underlayment is a critical layer installed beneath the primary roofing material, providing extra protection against water infiltration and weather damage. Choosing the right type ensures long-term roof performance and durability. Here’s what to consider:

1. Types of Roofing Underlayment

• Asphalt-Saturated Felt: Traditional and cost-effective; available in 15-pound and 30-pound varieties. It offers basic water resistance but is heavier and less durable than newer options.

• Synthetic Underlayment: Lightweight, tear-resistant, and offers superior moisture protection. It’s becoming the industry standard for most residential and commercial applications.

• Rubberized Asphalt: Self-adhering, waterproof membrane ideal for areas prone to ice dams or heavy rainfall. Commonly used in valleys, eaves, and around roof penetrations.

  
  

2. Climate Considerations

• In regions with heavy rain or snow, opt for synthetic or rubberized asphalt for better waterproofing.

• In hot climates, choose underlayments with UV resistance and high-temperature tolerance.

  
  

3. Roof Slope

• Low-slope roofs benefit from waterproof underlayments to prevent pooling and leaks.

• Steeper slopes may allow for more traditional felt or synthetic options.

  
  

4. Roofing Material

• Match underlayment to the roofing material—metal roofs often require specialized underlayments, while asphalt shingle roofs are compatible with most types.

  
  

5. Building Codes and Warranties

• Always check local building codes and manufacturer requirements for approved underlayment types to ensure warranty compliance.

  
  

Selecting the right roofing underlayment depends on your climate, roof design, and primary roofing material. Consulting with a roofing professional can help ensure optimal protection for your home.
