Revolutionary Roofing Underlayment

VPPCT Gold Badge

SlopeShield Plus Self-Adhered’s high drying capacity and black coloration (which absorbs heat from the sun when exposed during construction), accelerates the drying process of the underlying materials.

This combination helps to mitigate construction moisture which would otherwise be trapped by a non-permeable roofing underlayment.
