To protect against leaks, contractors typically nail one or two layers of “tar paper” to your roof before they install the tile. But “tar paper” doesn’t provide much protection because it’s made with conventional organic felt, which can become saturated with water and reduce its ability to prevent leaks. So even though you pay a large premium for a tile roof, your home — your most valuable asset — is potentially left vulnerable to water damage.

UnderRoof™ 2 Waterproof Protection is a specially-designed self-adhering leak barrier for tile roofs.

It provides maximum protection from leaks that can result from tile saturation, clogged gutters, wind-driven rain, or (in cold climates) freeze-thaw damage. Made with flexible SBS-modified compound and reinforced with a fiberglass-reinforced polyester core, UnderRoof™ 2 Waterproof Protection applies easily and can be left exposed for up to 180 days, if necessary. The heat-activated adhesive allows the product to be repositionable for ease of installation, but seals tightly once in place, providing a watertight barrier against leaks.

UnderRoof™ 2 Leak Barrier is a key part of the GAF Lifetime Roofing System, and has even earned the prestigious Good Housekeeping Seal. (See Details) The GAF Lifetime Roofing System has earned the prestigious Good Housekeeping Seal, which means that Good Housekeeping stands behind the products in this system.

Installation Considerations
(before installing)

• Review Application Instructions...

  On packaging as well as detailed instructions available at your place of purchase, at www.gaf.com, or by calling GAF Technical Services at 1-800-766-3411. Also be sure to carefully review the tile manufacturer’s application instructions.
  
  

• Substrates...

  Should only be installed over clean, dry surfaces, including unwrinkled underlayment, such as GAF Deck-Armor™ or ASTM D 226 #30 organic felt, or directly to flat substrates, such as plywood. Contact GAF Technical Services for suitability of other substrates.
  
  

• Temperatures...

  Should be installed when temperatures are 45°F (17.8°C) or higher.
  
  

• Venting...

  In applications over the full deck, it is particularly important to be sure that the roof assembly/attic is properly ventilated.

Homeowner’s Best Choice
