Stainless Steel Ledger Flashing With Simpson Strong Tie
primary reason for proper deck ledger flashing. EVERFLASHING was designed and
patented to help minimize water issues where the deck ledger board is attached.
The IRC (International Residential Code) for more than 12 years has stated that
approved corrosion-resistive flashing must be used. The only 3 corrosive-resistive
metals that are approved are G-185 (Z-MAX), stainless steel and copper. In
coastal and acid rain areas in the United States, stainless steel and copper are
your only 2 options.
I have set up 2 websites for proper deck ledger flashing installation:
The following is from the IRC’s code book for deck flashing:
R703.8 Flashing. Approved corrosion-resistant flashing shall be applied
shingle-fashion in a manner to prevent entry of water into the wall cavity or
penetration of water to the building structural framing components. Self-adhered
membranes used as flashing shall comply with AAMA 711. The flashing shall
extend to the surface of the exterior wall finish. Approved corrosion-resistant
flashings shall be installed at all of the following locations:
1. Exterior window and door openings. Flashing at exterior window and door
water-resistive barrier for subsequent drainage.
2. At the intersection of chimneys or other masonry construction with frame
or stucco walls, with projecting lips on both sides under stucco copings.
3. Under and at the ends of masonry, wood or metal copings and sills.
4. Continuously above all projecting wood trim.
5. Where exterior porches, decks or stairs attach to a wall or floor assembly of wood-frame construction.
6. At wall and roof intersections.
7. At built-in gutters.
NOTE: The new 2012 code also requires pan flashing on all sills.
Everflashing is 100% American made.
