## Description

EternaBond RoofSeal is a one-step semi-permanent repair system for virtually all roof types and roof accessories, from commercial building roofs to RVs and cargo trailers. EternaBond RoofSeal features a UV stable backing and creates a waterproof, moisture and air tight barrier with no additional sealing required. EternaBond RoofSeal remains flexible to temperatures as low as -57 degrees Celsius (-70 degrees Fahrenheit) making it virtually impossible to thermally shock the seam causing a leak. The adhesive side has a silicone lining that prevents it from sticking to other surfaces before application. Use RoofSeal over factory RV roof seams one time and never do roof seam maintenance again. From the manufacturer to the tradesman to the homeowner, more and more people are trusting EternaBond for permanent repairs on non pressurized leaks.
