ARYLIC ROOFING: PREPARING AN ASPHALT ROOF

The following procedures apply to all hot-applied or cold-applied asphalt sheet roofs, including mineral-surface roll roofing, built-up hot asphalt, and modified bitumen. Roofs that pond water may require structural repairs to eliminate low spots. Gravel-covered roofs should be stripped to bare asphalt and filled with several heavy coats of Acrylic AE. Badly deteriorated roofs with many large bubbles, deep fissures, and crumbling asphalt should be stripped completely, re-sheathed, and treated the same as new wood roofs.
