Roof Flashing provides weather protection for roof penetration. Used for flat roofs or on roofs that have up to a maximum slope of 20 degrees.

Roof Flashing is manufactured as follows:

  • Inner diameter sizes of 3 to 24 inches with a standard 20 gauge galvanize or an optional 20 gauge 304SS Stainless Steel
  • Outside diameter is 8 inches more than the inside diameter
  • Roof Flashing is made in two halves with a 2 inch overlap, caulked and riveted
  • Manufactured in either 20 gauge Galvanize or 304SS Stainless Steel.

NOTES:
  1. At temperatures ranging between 390° F and 480° F, the zinc-iron alloy layers in the galvanized steel will continue to provide a high level of protection from corrosion. However, there may be some peeling, changes in mechanical properties, and reduction in the corrosion protection. Recommended maximum service temperature is 390° F.
  2. For 304 SS metal, bluing may occur at temperatures of 800° F and above.
  3. Rock River Silicone Sealant and Red Devil HVAC/R High Temperature Silicone Sealant are not able to be painted.
