RoofSeal repair tape for roof leaks

Eternabond RoofSeal tape uses MicroSealing Technology to create a permanent watertight bond on roof surfaces. The black tape measures 4 inches wide by 25 feet long with a 65 mil thickness. It adheres to all materials except silicone and reaches full cure in one hour. UV protected construction resists degradation from sunlight exposure.

Sustained weather exposure and adhesion

The tape maintains its seal through temperature cycles, rain and direct UV radiation without cracking or peeling. MicroSealing Technology forms a continuous barrier that does not shrink or become brittle over time. One roll covers up to 8.3 square feet of roof area. The adhesive remains flexible to accommodate structural movement while keeping water out.

Surface compatibility and preparation checks

Verify the repair area contains no silicone coatings, sealants or residues because the tape will not bond to silicone. Clean the surface thoroughly so it is dry and free of oil, dirt or loose granules before application. Ensure the roof substrate is structurally sound enough to support the tape membrane. Plan coverage using the 25 foot roll length and 4 inch width.

Questions about this item

Will the 65 mil thick tape stay flexible in constant sun without cracking?

The tape uses MicroSealing Technology and is UV protected, so it resists degradation from daily sunlight exposure.

What surfaces can I apply this 4 in wide tape to without extra primers?

It bonds to all materials except silicone, so metal, rubber, EPDM, TPO, concrete and wood are ready to tape after cleaning.

Can I overlap new 25 ft rolls onto an old EPDM membrane that is already on the roof?

Yes, the tape adheres directly to aged EPDM and other roofing membranes as long as the surface is clean and free of silicone residue.
