Henry 181 Asphalt Saturated Glass Fabric Roof Repair Membrane, 6 in. x 150 ft. Roll, Black
Henry 181 is a black, open-mesh glass fabric saturated with asphalt, supplied as a 6 in. x 150 ft. roll. The 20 x 10 woven mesh delivers 75 lb/in. tensile strength, resists acid and heat, and will not rot, making it the reinforcement fabric for asphalt-based roof repair and waterproofing coatings.
Key Features:
- Woven fiberglass: Woven, open-mesh fabric made of inert, flexible filaments of pure glass.
- 20 x 10 mesh: 20 x 10 thread count provides stable reinforcement for asphalt coatings.
- High tensile strength: Rated at 75 lb/in. tensile strength for durable patched assemblies.
- Rot-proof: Will not rot or decay, unlike organic fabric reinforcements.
- Acid & heat resistant: Acid and heat resistant for demanding roof and waterproofing environments.
- 150 ft. roll: 6 in. x 150 ft. roll suits long seams, flashing and crack repair.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
This is the classic reinforcement fabric for trowel and brush-grade asphalt repairs: embed it wet-on-wet and keep edges lapped at least a couple of inches so the coating encapsulates the mesh completely. Use the 6-inch width for seams, splits and flashing details, and step up to wider fabric rolls for full-field reinforcement. Never leave fabric exposed; a bare top coat over the mesh is what makes the repair last.
Work with compatible coatings only and follow the coating manufacturer's instructions for hot or cold asphalt handling, including gloves and eye protection.
Pick up Henry 181 glass fabric, 6 in. x 150 ft., for reinforced asphalt roof repairs that hold.
