Your Roofing Underlayment Adhesive Could be Holding You Back

As the global roofing underlayment market grows, it’s important to ensure you’re using the right manufacturing materials to keep up with demand and performance needs. Find out how traditional underlayment adhesive technology could be holding you back.

Disadvantages with Traditional Roofing Underlayment Adhesives

Typically, self-adhered roofing underlayment adhesives have been an SBS-modified asphalt. While a common, inexpensive option, adhesives based in this type of technology possess:

  • Poor low temperature performance
  • Insufficient high temperature performance
  • Low tack
  • Ability to oxidize over time

As a result, roofing underlayment that uses this adhesive technology is unable to meet consumers’ roof performance needs and can cause other construction issues if left unfixed.

Advantages with Alternative Roofing Underlayment Adhesives

Instead, it’s a good idea to consider an alternative roofing underlayment adhesive, such as:

  • Extruded butyl
  • Hybrid butyl
  • Flame retardant butyl
  • SBC hot melt
  • Extruded SBC hot melt

In addition to increasing your technology options, these adhesives enable you to build better roofing underlayment faster. For example:

  • Their self-adhered membrane increase application speeds and reduce labor costs.
  • With a wide application temperature range, you’re able to use them in a variety of environments while resting assured that their aggressive tack will bond.
  • Repositionable, they also allow for superior walkability and choice of release film, which enhances manufacturing flexibility.

Further, by lessening ice dam damage and providing superior wind and rain protection, these roofing underlayment adhesives improve a home’s longevity and durability.
