CertainTeed's waterproofing shingle underlayments are applied under roof shingles during new construction or re-roofing to protect your home’s interior from winter leaks caused by ice dams and wind-driven rain.

Grip-Rite coatings and sealants offer maximum protection designed to repair, seal, bond, coat or patch any roof project.

Grip-Rite ShingleLayment is the only roofing underlayment with the high performance of a synthetic underlayment, and the finished look of a shingled roof.

Grip-Rite® modified bitumen membranes are manufactured from formulas using only the highest quality materials, to meet or exceed, industry standards.

For a roof to last, your roofing system must include protection from wind-driven rain.
