Overview
Grip-Rite SL154250LWE is described as a synthetic roofing underlayment made from polypropylene. It is described as a 48 in. x 250 ft. roll with 10 square coverage (1000 sq. ft.). It is described as ShingleLayment, a lightweight version of ShingleLayment 15-Pro, intended for use under mechanically attached roofing applications.
Key takeaways
- It is described as lighter, stronger, and more energy efficient than felt.
- It is described as made from tough woven polypropylene with high tensile substrates that resist tearing and blowoff from high wind exposure.
- It is described as UV treated to 180 days.
- It is described as evenly rewound, rolling out flat, and holding a chalk line.
- Buyers commonly describe it as underlayment and say it works as directed or does its job.
What the product is designed to do
This underlayment is described as a water shedding device designed to reduce the occurrence of leaks caused by wind-driven rain penetrating the primary roof system. It is described as used on steep-slope roofs beneath shingles, battened tiles, metal roofing, slate, wood shake and shingle, and simulated slate/shake prepared roof coverings. It is described as usable under any mechanically attached roofing application.
The 10 square roll size is described as saving costly labor and reducing waste, while providing a durable temporary cover and long lasting secondary water shedding protection. The surface is described as a non-skid polypropylene walking surface, with both top and bottom surfaces textured to provide traction underfoot and on the roof deck.
