Deckgard
Constructed with high-strength woven polypropylene and coated on both sides, this membrane has a high resistance to tear and can be left exposed for up to 6 months.
Deckgard can be installed under all types of roofing materials on sloped roofs : asphalt shingles, metal roofing, wooden shakes, slate, and synthetic tiles.
The membrane is warranted for 20 years.
To make shingle installation easier, Deckgard is lined every 2 inches.
