Roof Deck Protection - RoofPro


SBS-Modified All-Purpose Underlayment

Help Protect Your New Roof By Upgrading From Conventional Roofing Felts To Quality Roof Deck Protection

Quality Roof Deck Protection provides an extra layer of moisture protection between your roofing material and the roof deck, while helping to provide a better-looking roofing job.

Conventional roofing felts can often wrinkle or buckle during installation and can even fail before your roof covering is due for replacement. Quality Roof Deck Protection helps to avoid this by:

  • Helping to prevent wind-driven rain from infiltrating the roof system
  • Laying flatter to avoid “telegraphing wrinkles” through the roof covering
  • Helping roof coverings to lay flat and uniform Good House Keeping Seal
  • Resisting rot to help prevent premature roof system failure
RoofPro™ SBS-Modified All-Purpose Underlayment is a key part of the GAF Lifetime Roofing System, and has even earned the prestigious Good Housekeeping Seal.
