Vinyl Fascia
The wooden fascia board that encloses the front of an eave also
needs protection from the weather. To provide this protection, you
can install vinyl or aluminum fascia panels.
There are two procedures for installing vinyl fascia panels—one for
installations that include soffit, one for installations without soffit.
Installations without soffit
Nail undersill trim in place along the top of the fascia board.
Before installing the panel, create tabs along the top edge
using a snap lock punch.
Hook the bottom of the fascia panel under the bottom of the
fascia board. Push the top edge into the undersill trim,
as shown, or behind drip edge.
Secure the panel to the bottom of the fascia board with white
trim nails. Fasten at nail slot openings only (see illustration).
Do not face nail fascia panel.
When overlapping fascia panels, first cut a notch in the
underlying panel. The notch should be 1/8" deep by 1-1/2" long.
Slip the notched panel into the adjacent panel (see illustration).
To turn a corner, you must first fabricate a corner piece.
Cut a length of fascia panel so it extends 6" beyond the corner.
Mark a vertical line to indicate the position of the corner. Then cut
a 90° V-notch centered on the vertical line. Score it along the
vertical line and fold. Finally, create tabs along the upper edge
with a snap lock punch. The tabs must be raised on the outside
face of the panel.
Fit the panel on the corner, making sure to overlap the
preceding panel.
