Rolled Roof Underlayment: The Essential Layer of Protection

Rolled roof underlayment, also called roofing felt or liner, is a critical component of any roofing system. This layer, installed beneath your shingles, provides an extra barrier against moisture intrusion, protecting your roof deck and the underlying structure of your building.

Types of Rolled Roof Underlayment

  • Asphalt-Saturated Felt: The traditional underlayment option, felt paper offers basic water resistance at a budget-friendly price.
  • Synthetic Underlayment: Modern synthetic underlayments are lighter, stronger, and more water-resistant than felt, offering superior long-term protection against leaks.

Why Roof Underlayment Matters

Underlayment serves several important purposes for your roofing projects:

  • Moisture Barrier: Provides a secondary layer of defense against rain or water that might bypass your roof shingles.
  • Roof Deck Protection: Shields the roof deck from resin bleed-through in wood shingles and helps prevent damage from wind-driven rain.
  • Warranty Compliance: Many shingle manufacturers require synthetic underlayment to maintain full warranty coverage.

Choosing the Right Roof Underlayment

Consider these factors when selecting your roof underlayment:

  • Climate: In areas with heavy rain or snow, synthetic underlayment offers superior leak protection.
  • Roof Slope: Steeper roof slopes may benefit from the added durability of synthetic underlayment.
  • Shingle Type: Some roofing materials, like metal, require specific underlayment types.
  • Building Codes: Check local building codes for any underlayment requirements.

Rolled Roof Underlayment Best Practices

Ensure your roof underlayment performs at its best by following these tips:

  • Proper Overlap: Follow manufacturer instructions for shingle overlap to guarantee proper coverage.
  • Fasteners: Use recommended fasteners for secure attachment, preventing gaps or tears.
  • Avoid Wrinkles: Install underlayment smoothly to prevent wrinkles that could compromise water resistance.
