ShingleLayment LWE-GRE

The ShingleLayment LWE-GRE is a lightweight underlayment version of our ShingleLayment-15 Pro®. It features a substrate made from woven 8-by-8 scrim polypropylene and a non-skid polypropylene coating for a more secure walking surface. Both the underlayment’s surfaces — top and bottom — feature texture to increase friction and offer more traction. You can use ShingleLayment under any roofing project using mechanical attachments.

Enjoy a high-quality product with impeccable performance. You get a minimized risk of damage with a lighter, quicker-to-install product. The shingle underlayment solution provides toughness and durability, increasing confidence on the project site.
