Roof leak repair for oil-based sealing
Henry HE208R042 is a black, oil-based roof leak repair supplied in a 0.9 gal pail. It uses an asphalt resin that conforms to ASTM D3409 and ASTM D4586. The product is intended for sealing roof leaks at room temperature. It contains a chemical listed under California Proposition 65.
Fits standard roofing maintenance workflows
The pail format allows direct application with a brush or trowel without additional mixing equipment. Coverage is rated at 12.5 sq ft per gallon, so the container addresses small to moderate repair areas. Application at room temperature frees the installer from heating tools or hot-melt apparatus. VOC content is 300 g/L, which may affect use in regulated air-quality districts.
Sustained exposure relies on asphalt durability
Once cured, the asphalt resin forms a flexible membrane that resists weathering over time rather than providing only a temporary surface film. The oil base remains pliable through thermal cycles, reducing the risk of cracking under repeated expansion and contraction. Long-term performance depends on proper surface preparation and the thickness achieved at the rated coverage.

Questions about this item
How many square feet does one gallon of this roof leak repair cover?
The product covers 12.5 sq ft per gallon at the recommended application rate.
Does the oil-based asphalt formula produce strong fumes during all-day application?
VOC content is 300 g/L, so expect noticeable solvent odour; ventilate the work area continuously.
Can I brush this directly onto a damp roof deck or must the surface be bone-dry first?
Application temperature is room temperature; the surface should be clean and dry for proper adhesion.
