Customer Questions & Answers

Will it seal screws

Asked by: rick
Grace Ultra is designed to seal around fasteners used to secure roofing materials, and is tested for this property using roofing nails. It will seal around other fastener types, such as screws. The dimensions of the screw can significantly affect the seal, with larger screws being more challenging. For added protection, apply a compatible sealant, such as silicone, to the head of each screw.

What is the actual thickness of this product.

On this site it says 1.18110 but I'm sure it's not over an inch thick. Is it .118 or .181 of an inch.
Asked by: BOB
The product is 30 mils (0.76 mm) thick. We will update the specs. It should read: 0.03 inches

1. can this be used on al low slope roof and how many rolls would I need to cover 2000 square feet ? Do I need anything else to prevent ice jam leak ?

Asked by: DNS
Grace Ultra, and other Grace underlayments, are designed for use in roofing applications where the slope is 2:12 or greater. Grace Ultra seals to the roof deck material, seals at overlaps, and seals around fasteners to prevent leaks due to wind driven rain and ice dams. You will likely need about 12-13 rolls to complete your project.
