Well-Seasoned on All Forms Of Radiation Shielding

Lead Roof Flashings

Lead flashings are a weatherproofing product placed over roof vents or wall joints to prevent moisture from seeping into construction material and causing mold or other damage. Unlike flashings made from rubber, lead roof flashings are more resistant to punctures, tears, and other damage. Lead vent flashings will handle environmental elements longer than any other type of flashing material.  

Adjustable pitch flashings come in a range of widths and thicknesses and weights to accommodate various roof thicknesses. Industrial lead roof flashings effectively minimize water penetration in roof valleys and around protrusions such as: 

  • Chimneys
  • Door Openings
  • Skylights
  • Vents
  • Walls
  • Windows

Customized Lead Roof Flashings for Commercial and Industrial Applications

Radiation Protection Products offers custom fabricated lead roof flashings consisting of lead pipe boots burned to a sheet lead base. There are different codes of lead roof flashing to determine the weight or thickness of the lead sheet:

  • Code 3 lead flashings are 1.32mm thick and weigh 3 lbs. per square foot. This is the thinnest gauge of commercial roofing lead. Code 3 lead roof flashing melts easily for welding and works well in lightweight applications.
  • Code 4 lead flashings are 1.80mm thick and weighs approximately 4 lbs. per square foot. This lead flashing is highly workable and versatile for a variety of roofing applications or use as window and cover flashings.

Our standard lead flashing weights include 2-1/2, 3, and 4 lb. options with heavier weights available by special order. Adjustable lead roof vent flashings are also available upon request. We manufacture all lead flashings and shielding products in accordance with Lead Industries Handbook and all NCRP Applicable Reports s (#33, #35, #39, #40, and #49), and NBS, HB. #114.
