FRAMING PREP FOR SOFFIT PANELS
When installing the soffit:
1) Straighten the rafter tails by pulling and snapping a chalk line across the
ends of the tails and then trimming them as necessary.
2) Install a solid wood sub-fascia on the ends of the rafter tails or install
blocking between the rafter tails as needed.
3) If the soffit is to be installed level across its width, add nailers at every
rafter or truss to provide support.
4) If the eaves are longer than 12 ft., measure and trim the first HardieSoffit
®
panel making sure that the end falls in the middle of a nailer.
5) Using the subfascia as a guide along the edge, carefully position the panel
and secure with 4d common galvanized nails spaced no greater than 8 in.
o.c. at all panel edges and on all intermediate framing members.
6) Continue with additional pieces until the run is complete.
Measure distance from corner to center of framing block.

CUTTING 45° HIP ROOF SOFFITS
Hip roof soffits continue level around the
corners of a house. The soffit panels
should join at the corner with 45° angle
cuts. To create these corners:
1) First measure from the corner to the
perpendicular framing member closest
to, but not over 12 ft.
2) Using that measurement and pulling
from the factory cut end of the soffit
panel, mark the outside edge of the
soffit panel for the long point of the
45° cut.
3) After cutting the 45° angle, position the
panel on the soffit framing and check
the fit on both ends before fastening.
4) Begin nailing at the 45° cut end and
work toward the factory end.
