the building structural framing components. The flashing shall extend to the surface of
the exterior wall finish and shall be installed to prevent water from reentering the
exterior wall envelope. Approved corrosion-resistant flashings shall be installed at all of
the following locations:
1.
At top of all exterior window and door openings in such a manner as to be
leakproof, except that self-flashing windows having a continuous lap of not less than
11/8 inches (28 mm) over the sheathing material around the perimeter of the opening,
including corners, do not require additional flashing; jamb flashing may also be omitted
when specifically approved by the building official.
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.
Replace with:
R703.8 Flashing. Approved corrosion-resistant flashing shall
be applied shingle-fashion in such a manner to prevent entry of
water into the wall cavity or penetration of water to the building
structural framing and structural sheathing components or behind wood or other
siding materials subject to water caused deterioration. 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:
