Henry #208R Rubberized Wet Patch Roof Cement – 1 Gallon

Henry’s #208R Rubberized Wet Patch Roof Cement delivers a professional-grade seal for fast, reliable roof repairs. Formulated with SBS-modified asphalt, this thick, elastic compound adheres instantly—even on damp or underwater surfaces—creating a flexible, watertight bond. Its smooth, black finish blends seamlessly with most roofing materials, making it ideal for emergency patching and routine maintenance alike.

Whether you’re sealing leaks around flashings, repairing cracks in rubber roofing, or reinforcing seam areas, this heavy-duty cement stands up to harsh weather and temperature extremes. Easy to apply with a trowel or putty knife, it cures to a tough, weatherproof layer that resists cracking, splitting, and shrinkage over time.
