Henry All-Season Roof Repair

Henry 208R is the original all-season rubberized roof repair compound — still the most-used emergency roof product in Canada after decades in the trade.

Unlike standard roofing cements, 208R is formulated to bond to wet surfaces. If it's actively raining and you need to stop water from getting in right now, this is the product. It's applied with a trowel or gloved hand, sticks to asphalt shingles, metal flashings, and most roofing substrates, and remains flexible through Canadian winters.

The 946 mL quart is enough for isolated repairs: a failed shingle, a skylight flashing, a chimney flashing joint, or a small area of cracked flat-roof membrane. For larger areas or pail quantities, see the 3.78 L and 18.9 L options.
