Blister/ Ridge Repair in Hot Asphalt Video

This video illustrates the method for repairing a membrane blister or ridge on an existing 4-ply built up roof (BUR) system, with asphalt and pea gravel surfacing. The area is cleaned and prepared, the membrane anomaly is removed, and 4 plies of felts are each fully adhered in hot asphalt, with a flood coat of asphalt and new pea gravel applied for protection and durability.
