Finishing a gable end
To install around gable ends, make a pattern that duplicates the slope
of the gable:
● Lock a short piece of siding into the gable starter course (i.e., the last course
before the gable starts).
● Hold a second piece of siding against the J-channel at the slope of the gable.
Mark the slope with a pencil on the short piece of siding. Check the angle
template every few courses.
● Remove the short piece and cut along the pencil line as a pattern for the
gable angle cuts. Repeat the procedure on the opposite side of the gable.
● It may be necessary to fasten the last panel at the gable peak with a trim
nail. Use a 1 1/4” to 1 1/2” nail. This is the only time a nail should be placed
in the face of the vinyl siding.
Eaves treatment
The last course of siding may be cut to fit the eaves opening.
● Measure from the soffit to the base of the upper lock on the previous course
of panels. Subtract 1/4’’. Mark this dimension on the panel to be cut, measur
-
ing from the bottom edge of the panel. It is a good idea to check the dimen-
sion in several locations along the length of the wall.
● Using a snap lock punch, punch the vinyl siding along the cut edge every 6”,
so the raised tab is on the outside face.
● Push the siding into the undersill trim that has been nailed in place along
the top of the wall. Furring may be needed to maintain the face of the panel
at the desired angle. The raised tabs will catch and hold the siding firmly in
place.
Transition from horizontal to vertical
● Finish the last course of horizontal siding with the J-channel and/or finish
trim. Install a drip cap and a J-channel. The top piece of J-channel must
have minimum 1/8” diameter weep holes drilled no more than 24” apart to
allow for water runoff.
Transition transition from brick to vinyl siding
● Caulk where the sheathing meets the brick or stone exterior.
Flashing should be caulked where it meets the brick or stone and
a drip cap should be in place.
● If horizontal siding is used, a J-channel or starter strip may be used.
If a starter strip is used, it is necessary to provide at least 3/8” clearance for
proper engagement of the siding.
● Use a J-channel to receive vertical siding; remember to drill minimum 1/8”
diameter weep holes no more than 24” apart.
