Henry Co HE208R042 Rubberized Wet Patch Roof Cement 1 Gal

Product Description

The HENRY CO HE208R042 is a rubberized wet patch roof cement designed for emergency and routine patching of leaks on flat and low-slope roofing systems. Formulated with rubber modifiers, this wet-applied cement bonds to damp or wet surfaces, making it suitable for repairs that cannot wait for dry conditions. It is used by roofing contractors and maintenance technicians to seal around flashings, vents, skylights, and membrane seams. The gallon format covers small to medium patch jobs and is part of a four-unit case pack.

This roof cement is suited for residential and light commercial roofing applications, including built-up roofing, modified bitumen, and asphalt shingle systems. Typical install scenarios include emergency leak repair during wet weather, flashing termination sealing, and perimeter edge sealing. It is commonly applied in situations where standing water or active moisture is present and standard cold-process cements are not appropriate. Roofing contractors and general maintenance crews are the primary installers.

Installation Notes

Application is typically performed by licensed roofing contractors or qualified maintenance personnel. Clean the repair area of debris and loose material before applying. Use a trowel or putty knife to work the cement firmly into seams and around penetrations, feathering edges for a watertight seal. Follow all local building codes and manufacturer application guidelines for coverage rates and minimum film thickness.
