Seam & Repair Tape · 4" × 50' roll
Eternabond RoofSeal Tape
Eternabond RoofSeal is not tape in the conventional sense. It is a microsealant system in roll form.
The adhesive side uses Eternabond's proprietary microsealant chemistry — a compound that penetrates the surface substrate and bonds at the molecular level. On EPDM rubber roofing, it doesn't just stick on top — it bonds into the membrane. Pull it off and you take the roof with it. It doesn't come undone.
A full 50-foot roll of 4-inch tape is the standard for a complete seam overhaul on a midsize RV roof or a full seam run on a flat-roof addition. The 4-inch width bridges most standard seam widths with overlap to spare.
Compatible with EPDM, TPO, modified bitumen, fibreglass, aluminium, galvanized steel, and most roofing substrates. Apply to a clean, dry surface — a single IPA wipe-down is sufficient preparation on most roofs.
This is the product that ends the conversation about whether a seam is going to leak again.
