Henry Wet Patch Roof Cement – 11 oz, Black

Engineered for fast, reliable roof repairs, Henry Wet Patch Roof Cement delivers a professional-grade seal in any weather—rain or shine, wet or dry. Its rubberized, SBS-modified asphalt formula adheres tenaciously to a variety of substrates, creating a flexible, watertight barrier that resists cracking, peeling and UV damage. Ideal for emergency patching and routine maintenance, this cartridge-style cement can be applied even in cold temperatures, ensuring leaks and openings stay sealed year-round.

Perfect for homeowners and contractors alike, it easily fills holes, cracks and splits around chimneys, vents, gutters, flashings and metal edging. Once cured, the black finish blends seamlessly with most roofing materials, from composition and mineral-surface capsheets to metal, masonry and asphalt-coated surfaces.
