Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Henry Smooth Black Asphalt All-Weather Roof Cement 1 gal offers a reliable, weather-ready solution for sealing, patching, and protecting asphalt roofs. This fiber-reinforced, cold-applied cement is designed to withstand the elements, delivering durable patches that blend with your roof’s asphalt coloring while staying flexible over time. Packaged in a convenient 1-gallon can, it’s ready to tackle leaks and worn seams with a smooth, seamless finish.

Why this Henry roof cement stands out

  • Cold-applied, no heat required: Apply directly to the roof surface without torches or heated equipment, making on-roof repairs faster and safer.
  • Fiber-reinforced for durability: The added fibers boost adhesion and tear resistance, helping the patch hold up against wind-driven rain and temperature changes.
  • All-weather performance: Engineered to perform across a wide temperature range, sealing out moisture in both hot summer sun and cooler seasons.
  • Asphalt-based, oil-based formula with a black, smooth finish: The deep black color matches common roofing membranes while delivering a sleek, uniform appearance once cured.
  • Long-lasting protection — up to 10 years: When applied according to the label, it provides extended protection against leaks and deterioration.
  • Easy packaging and handling: Comes in a durable 1-gallon can for convenient storage and application on mid-sized to larger roof areas.

Ideal use cases and practical tips

This all-weather roof cement is well-suited for:

  • Patching small leaks around flashing, vents, and nail heads on asphalt or built-up roofs.
  • Sealing worn seams and cracks in low-slope or flat roof sections where a flexible, long-lasting seal is beneficial.
  • Temporary to semi-permanent repairs that bridge the gap until a full reroof, thanks to its durable, weather-resistant performance.

Application tips: Prepare a clean, dry surface before applying. Use a trowel, putty knife, or brush to apply a liberal, even layer, feathering the edges to ensure a seamless blend with the surrounding roof. Allow sufficient cure time under ambient conditions; actual curing can vary with temperature and humidity, so consult the product label for specific guidance. For best results, apply in moderate weather and follow safety guidelines appropriate for on-roof work.
