Abstract
A method of maintaining as well as restoring the condition of weathered asphalt shingles and strips which are applied to flat roofs, pitched roofs, or vertical walls. The process involves applying resaturant neat or as a water emulsion. Suitable resaturants include fatty acid methyl esters, petroleum distillates, and water emulsions thereof. The process restores the suppleness and softness of the weathered shingles or strip and adds about three years to the lifetime of the roof. The process may be repeated for additional lifetime extension.
