Tips for Using Synthetic Roofing Underlayment

As synthetic roofing underlayment continues to take over the roofing market, it’s important to ensure you’re using it properly. Read on for tips on how to use this new material.

Tip #1: Know the Type of Roofing Material

Synthetic roofing underlayment offers several benefits for manufacturers, including:

  • Increased strength
  • Greater safety
  • Improved walkability

However, it is not necessarily compatible with all roofing materials. When using materials such as steel, wood or tile, be sure to first check for underlayment compatibility.

Tip #2: Understand the Moisture Vapor Transmission Rate

This type of underlayment has a low moisture vapor transmission rate when compared to other underlayment options. This means that moisture will not be able to escape through the roof; it forms a waterproof barrier. Be sure to consider other ventilation methods during the construction process.

Tip #3: Pay Attention to Fastening Needs

Most synthetic roofing underlayment materials require certain types of fasteners during installation. In particular, this may include capped nails as opposed to staples. Ensure you verify the manufacturer’s specifications prior to installation.

Tip #4: Use the Right Roofing Underlayment Adhesive

Adhesives also play an important role in the functionality and longevity of synthetic roofing underlayment. It’s a good idea to consider the value in a self-adhered adhesive that offers:

  • Faster application speeds
  • Aggressive tack
  • Repositionability
  • Ease of use
  • Wide application temperature range

Additionally, this type of adhesive can deliver the following application benefits:

  • Tenacious, long-term adhesion across environmental conditions
  • Superior protection against severe weather under any roofing material
