GUTTERS
If gutters are installed, they should not terminate against siding or trim.
Maintain a 1-in. clearance between the siding and the gutter end-cap.
Kickout flashings should be installed on the roof above to divert roof
runoff into the gutters and away from the 1-in. gap.
The amount of water that can be generated from a rain shower or
storm can be substantial. Managing the collection and distribution of this
water is important over the life of a home.
TIP: James Hardie recommends the use of rain gutters whenever possible.
Code Reference: “1503.2.1 Locations. Flashing shall be installed at wall and roof intersections, at gutters,
wherever there is a change in roof slope or direction and around roof openings…”
General Installation Requirements (continued)
Due to the volume of water that can run down a sloped roof, one of the
most critical flashing details is where a roof intersects with a sidewall.
Install a self-healing adhesive-backed membrane along the roof/wall
intersection before flashing. The membrane on the wall should extend
behind the eaves framing and should be installed before the sub-fascia
or trim goes on.
The roof should then be flashed to the wall with step flashing
positioned at every shingle course. Where the roof begins at its lowest
point, install a kickout flashing to deflect water away from the siding.
Kickout flashing can be made by cutting and bending a piece of step
flashing at an angle. The water-resistive barrier on the wall should then
lap over the step flashing.
There are several companies that sell pre-made kickout flashings
that are designed to divert water away from the wall. Below is an
example of a preformed polypropylene kickout. Be sure to follow all
manufactures installation instructions.

WARNING
Caution: The kickout flashing shall be min. 4 in. x 4 in. as required by IRC
code R905.2.8.3 and be angled between 100° - 110° to deflect water from
dumping behind the siding and the end of the roof intersection
!
