Henry Co HE208030 Wet Patch Roof Cement 1 Quart

Product Description

The HENRY CO HE208030 is a wet patch roof cement formulated to bond and seal on both wet and dry surfaces. This asphalt-based compound fills and repairs holes, cracks, and splits in asphalt-coated, composition, and metal roofing systems. It seals metal joints, flashings, and penetrations including chimneys, skylights, and vent pipes. It also adheres asphalt shingle tabs and maintains a workable bond even when applied under standing water. Roofing contractors and general contractors use this product for emergency patches and routine maintenance on low-slope and steep-slope residential and light commercial roofs. The product ships in cases of 12 quart units.

This roof cement is suited for a wide range of common roofing repair tasks. Typical applications include sealing flashing at roof penetrations, repairing open seams on composition shingles, patching small holes in metal roofing panels, and re-adhering lifted shingle tabs. Because it bonds on wet surfaces, it is well-suited for urgent repairs during or after rain events without requiring the substrate to dry first. Roofing professionals and skilled tradespeople working on residential and light commercial structures will find this compound applicable across multiple repair scenarios in a single visit.

Installation Notes

This product is typically applied by roofing contractors or experienced general tradespeople following applicable local roofing codes. Before applying to non-emergency repairs, clear loose debris and standing water from the repair area where conditions allow. Apply using a trowel or putty knife, pressing the cement firmly into cracks or voids and feathering edges to promote adhesion. Do not thin the product or apply in a continuous heavy build over large unsupported spans.
