EternaBond RV RoofSeal Leak Repair Tape 4" x 50' White — Weatherproof, UV-Stable MicroSealant

EternaBond RV RoofSeal is a professional-grade, weatherproof tape that creates a permanent, watertight seal for RV and mobile home roofs. EternaBond's RoofSeal combines a UV-stable white backing with MicroSealant Technology to bond securely to a wide range of roofing materials and common building substrates. Designed for quick, one-step repairs, this 4" x 50' roll adheres immediately when its peel-off liner is removed and resists stretching, shrinking, and weathering across temperature extremes down to -20°F. Made in the USA, it’s formulated to stop leaks at seams, tears, flashings, skylights, gutters and more without priming on most surfaces.

How does this tape perform on different roof materials?

RoofSeal is engineered to adhere to many membrane types and rigid surfaces, offering durable adhesion without special primers on most substrates. It bonds to EPDM, TPO, most PVC, Hypalon/CSPE, modified bitumen, metal, tile, shingles, and many construction boards and plastics.

• Bonds to rubber membranes (EPDM), TPO and most PVC roofing.
• Adheres to metal roofs including aluminum and galvanized steel.
• Works on asphalt and coal-tar BURs, modified bitumen, tiles, shingles and common sheathing (OSB, plywood, gypsum).
• Compatible with many plastics and composites like fiberglass, polystyrene, polyethylene and propylene.

What conditions and preparation are required for a reliable repair?

Clean, dry surfaces ensure the strongest bond; remove dirt, oils and loose debris before applying. While no primer is needed for most materials thanks to MicroSealant Technology, using a recommended cleaner improves adhesion and longevity.

• Surface must be clean and dry; use an appropriate cleaner for best results.
• Apply by removing the removable liner as you press the tape into place to avoid contamination.
• Can be installed in cold temperatures down to -20°F; still follow surface prep guidance.
• Use firm pressure or a roller to eliminate air pockets and ensure edge adhesion.

How durable is the seal and how long will it last?

The tape's UV-stable white backing and flexible adhesive resist environmental movement and sunlight exposure, delivering a long-term seal for leak repairs and seam restorations. It expands and contracts with roof movement, reducing stress at the repair site.

• UV-stable white surface protects against sun degradation and keeps repairs discreet.
• Formulated to flex with temperature changes to avoid lifting or splitting.
• Provides an air-, moisture- and water-tight barrier for permanent repairs when applied correctly.
• Made in the USA to industrial standards for consistency and performance.
