MetaLayment™ Insualtion

When it comes to applying a metal, shingle, slate or mechanically-fastened tile roof, you need an underlayment that will increase the protection of your investment. Fulfill that need with CertainTeed's MetaLayment. Clogged gutters, high winds and ice dams cause water to accumulate on lower sloped roofs which can cause damage. MetaLayment can combat these elements. It is waterproof, does not rip and seals around nails driven through it.
