## Description

Seal any rip, tear, or open seam in any surface with RoofSeal. RoofSeal is the best solution for leak repair. It is the choice of professional roof repair specialists, on virtually all roof types including EPDM, TPO, Hypalon, most PVC, modified, all metals, even copper and Kynar coated metals, tile, wood, concrete, etc. RoofSeal even works great on land-fill and pond liners. Our specialized backing has proven to be UV stable, even after 19 years in full sunlight. Our MicroSealant has a built in primer which allows RoofSeal to bond with the surface it is installed on. Perfect for re-seaming all roofs, regardless of the material. RoofSeal makes a permanent water-tight seal. Elongation factor greater than 700% guarantees RoofSeal will flex, expand and contract in all conditions! Can be installed to -20°F (with our EternaPrime). Sag rating of over 250°F.

Review: We purchased this in the fall of 2019. Very expensive RV waterproofing repair tape but worth the price. As almost all other users proclaim, the best product for seam seals and repairs. Comes in a roll with a clear plastic film once removed, sticks very well, very tacky to begin with and then becomes permanent and difficult to remove. We are amateurs but are DIY fans. We had to seal a badly repaired RV roof seam and moulding where previous owner screwed more screws and applied some kind of putty that dried, cracked and disintegrated over the years. We needed a quick, economical fix. Even though this tape is EXPENSIVE, in the big picture it is a quick, cheap solution and solved our problem. The product manufacturer and users recommend using a roller which works if you have a perfect flat surface to work with. Our situation was with screw heads and chunky, bumpy leftovers of the putty used previously. So make sure you clean the surfaces well with a solvent, we went with isopropyl alcohol. Then do a dry run with the tape before removing the clear film. You literally have one shot at this. I removed the film while rolling out the tape and my wife pressed it into position and used her bare hands to apply pressure to the tape. This created best results for us because of the uneven surface. Eternabond has been applied for about 7 months now and no leaks. This tape can be used for multiple applications but be careful, it is easy to make a sticky nightmare with, Definitely recommend this very expensive product.
Review: I am installing this on rv roof to cover up seal seems around fans and vents as sealer is starting to separate . It is thick and easy to lay down just have to be careful to not have air pockets .Only time will tell whether it stands up to weather and sun rays
