Henry Co HE208061 Wet Patch Roof Cement 3.5 Gallon

Product Description

The HENRY CO HE208061 is a wet patch roof cement designed for emergency and routine repairs on both wet and dry roofing surfaces. This fiber-reinforced mastic adhesive bonds to surfaces even when standing water is present, making it a reliable option when weather conditions prevent a dry repair window. Weighing 37 pounds per container, the 3.5-gallon unit provides substantial coverage for flashing repairs, sealing seams, patching splits, and repairing membrane edges. Roofing contractors and general contractors working on low-slope or flat residential and commercial roofs rely on this type of product to maintain watertight integrity without waiting for dry conditions.

Wet patch roof cement is commonly applied to built-up roofing systems, modified bitumen membranes, metal flashings, gutters, and asphalt shingles. It is suited for use around chimneys, vents, skylights, and roof penetrations where water infiltration is an active concern. This product is appropriate for both emergency repair situations during wet weather and scheduled maintenance work. Field applicators typically use a trowel or putty knife to work the cement into cracks, around flashings, and along seams to form a durable, weather-resistant seal.

Installation Notes

Application is typically performed by a licensed roofing contractor or qualified tradesperson familiar with low-slope roofing systems and applicable local building codes. Remove loose debris and standing water from the repair area where possible before application. Apply using a trowel or stiff putty knife, feathering edges to ensure full adhesion and water shedding. Avoid applying in freezing temperatures unless the product label specifically permits cold-weather use.
