Roof underlayments featured in Metal Architecture’s October 2021 issue.

Bitec Inc.

Bitec’s MAT-40 durable metal and tile roof underlayment has a self-adhering membrane. It provides waterproofing protection for commercial and residential applications. It weighs 40 pounds per 100 square feet, and resists punctures and tears. MAT-40 roof underlayment has a top coat consisting of high-strength, dimensionally stable polyester combined with fiberglass scrim. On the bottom surface, the roll is coated with a styrene-butadiene (SBR) polymer modified adhesive. This allows for a silicone-treated split release film to easily attach to the membrane, which eases installation.

CertainTeed Corp.

CertainTeed’s WinterGuard roof underlayment for metal, shingle, slate and mechanically fastened tile roofs is self-adhering and slip-resistant. WinterGuard metal roof underlayment is unaffected by high temperatures caused by sun exposure during installation or when placed under metal roofing. WinterGuard roof underlayment protects roofs from clogged gutters, high winds and ice dams that cause water to accumulate on lower sloped roofs. The roof underlayment is waterproof, does not rip, and seals around nails driven through it.

GCP Applied Technologies Inc.

GCP Applied Technologies’ GRACE Ice and Water Shield HT is a high temperature, self-adhered roof underlayment. It is composed of two waterproofing materials: a rubberized asphalt adhesive and high-performance polymeric film with UV barrier properties. The rubberized asphalt surface is backed with a fold-less release paper that protects adhesive quality. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to roof decks. A RIPCORD embedded in the adhesive allows applicator to split release on demand, making it easy to apply in detail areas.

MFM Building Products Corp.

MFM Building Products’ Wind and Water Seal is a high temperature, self-adhering roof underlayment for metal roofing systems where high heat is generated. The 40-mil-thick roof underlayment has an embossed polymer traction surface that self-seals around roofing fasteners. Its styrene butadiene styrene (SBS) adhesive system is rated to 250 F. The Wind and Water Seal is applied directly to roofing decks for whole roof coverage. It provides secondary water protection roofing systems fail or leak. Additionally, Wind and Water Seal is a vapor barrier, so proper ventilation of the roof system is needed to ensure proper performance. The roof underlayment comes in 36-inch by 67-foot (2 square) rolls. It has a 10-year warranty.
