Henry Wet Patch Black Asphalt All-Weather Roof Cement 10.1 oz is a weather-ready, cold-applied sealant designed to keep asphalt roofs watertight through every season. This fiber-reinforced cement is built to move with the roof, resisting cracking and letting you patch leaks quickly without heat or special equipment.
What sets this Wet Patch formulation apart is its combination of durability, strength, and ease of use. The fiber reinforcement adds tear resistance and flexibility at seams, patches, and penetrations, while the solid black finish blends seamlessly with asphalt shingles and roofing substrates. It’s a non-water-based, all-weather solution that stands up to wind-driven rain, temperature fluctuations, and UV exposure for years of reliable performance.

Why choose Henry Wet Patch over other roof cements?
This product combines the reliability of a true asphalt cement with fiber reinforcement, delivering a patch that remains flexible as the roof expands and contracts. The cold-application format saves time and eliminates the hazards of hot-applied roof repair, making it a safer, more convenient option for both DIY enthusiasts and professional roof crews. Its solid black appearance helps it blend with common asphalt roofing aesthetics, resulting in repairs that look as good as they perform.
Application tips for best results
- Prepare the area by cleaning away dust, dirt, and loose material; ensure the surface is dry for optimal adhesion.
- Cut the nozzle to achieve your desired bead width, load the cartridge into a standard caulk gun, and apply a consistent bead along the defect.
- Press and smooth the cement to ensure intimate contact with the substrate, feathering edges for a seamless finish.
- Allow the patch to cure in dry conditions; avoid heavy moisture until the seal has set for best longevity.
