BIO ROOF WP plastic, glass-reinforced, all purpose roof cement is ideal for temporary roof repairs when surfaces are cold and wet and for more permanent repairs before coating with other types of fibered roof coating. This unique roof cement applies well in hot or cold weather and on damp or dry surfaces. BIO ROOF WP can be used for patching cracks and breaks in roofing surfaces, firewalls, chimneys, gutters and flashings. It can also be used for installing new flashing. BIO ROOF WP stops leaks when applied around vent pipes, in valleys, around spouts, skylights, gutters and chimneys. It can be used to line leaky gutters and troughs, and to seal cracks in chimneys, walls and foundations.
