Henry Co HE208071 Wet Patch Roof Cement 5 Gal

Product Description

The HENRY CO HE208071 is a wet-patch roof cement formulated to seal and patch roof leaks on both wet and dry surfaces. This heavy-body asphalt-based compound bonds directly to roofing substrates even when standing water is present, making it a practical choice for emergency leak repairs where drying conditions are not ideal. It ships in a 5-gallon container and weighs 51 pounds. Roofing contractors and general contractors use this product for flat, low-slope, and steep-slope roof repairs on residential and light commercial structures.

This roof cement is suited for patching cracks, gaps, and penetrations in asphalt shingles, built-up roofing, metal flashing, and similar substrates. The wet-surface adhesion characteristic makes it particularly useful for storm-damage repairs and other urgent field conditions where waiting for a dry surface is not an option. It is applied cold, requiring no heating equipment on the job site.

Installation Notes

Applied by roofing contractors using a trowel or putty knife. Clear loose debris and remove any standing water as much as conditions allow before applying, even though the product bonds in wet conditions. Work the cement firmly into cracks and feather the edges to promote adhesion. Follow local building codes and roofing manufacturer guidelines for repair procedures.
