Copper Roll Flashing
Copper roll flashing can be used in a wide variety of applications and copper roll flashing is especially popular with treated lumber or in areas requiring a very high level of corrosion resistance. Union's copper roll flashing utilizes a polymer backing to isolate it from dissimilar metals. As copper roll flashing weathers, it retains a light green patina. Union offers 3 ounce copper in 8" and 20" wide rolls that are 20' in length.
