Heavy Duty Bitumen Roof Repair Tape for Waterproof Sealing
✔️ Single roll measures 39in wide, 393in long, and 3mm thick silver tape

This self sealing bitumen tape is an asphalt based waterproof patch made with a polymer modified adhesive and a durable aluminum top layer. It works best for covering roof leaks, fixing cracked gutters, sealing window frames, and repairing RV awnings or boat surfaces that lose their weather barrier over time. Users just peel the release film, lay the strip flat, and press out trapped air to lock in a permanent water barrier that handles heavy rain and summer heat without shrinking or peeling.

Key specifications:
✅ Pack contains one roll measuring 39 3/8 inches or 100 millimeters wide
✅ Total length covers 393 7/8 inches and 9999 millimeters along the full run
✅ Overall thickness sits at 1 3/16 inches or 3 millimeters across the layer
✅ Silver top layer reflects heat and shields the adhesive from direct sunlight

💡 What makes asphalt repair tape effective for stopping roof leaks fast?
The polymer bitumen core flows into uneven gaps when warm and cures into a hardened seal.
- Cold weather does not inhibit the bond since the rubberized compound stays flexible near freezing.
- Overlapping edge strips creates a continuous shield that resists wind uplift and standing water runoff.
- Direct application onto dry dirt, metal, or concrete skips the need for messy liquid caulks and primer coatings.
