Synthetic Roofing Underlayment

Synthetic Roofing Underlayment

Say goodbye to felt with GreenGuard’s premium Synthetic Roofing
Underlayment. Engineered with 100% synthetic polypropylene weave and
modified polyolefin coatings, it is stronger, lighter, more cost-effective, and
more durable in inclement weather. With unique slip-resistant coatings on
both sides, it provides a safer, more secure work surface. And because it
contains no organic material, it does not support mold growth or
rot. The underlayment installs easily with plastic cap staples
or roofing nails and can remain exposed up to 6 months.
