Installation Instructions

Accessories and Trim
We recommend the use of
Restoration Millwork cellular
PVC trim. If pocketed
accessories are desired, a
1" minimum pocket height
is required to cover the
built-up shingle projection.
Shingles must maintain a
1/16" minimum clearance
from any trim edge.
Finishing the Top Course
To nish the top course
of the siding, apply a trim
board over the shingles
to conceal the fasteners.
First determine the shingle
length required to ll the remaining space. Be sure to plan
for trim width, fastening and shims if used. Two fasteners
are required to secure the shingle to the wall. Partial
shingles with no staple zone will require pre-drilling and
hand nailing.
Under a window or opening
As above, apply a trim board to conceal the fasteners.
Partial shingles with no staple zone will require pre-drilling
and hand nailing.
Over a window or opening
Shingles installed above window and door headers must
be spaced 1/4" to 1/2" above the ashing to ensure proper
drainage.
Gables and at the Rake
Similar to the top course under a soft or window, cut
shingles to appropriate angle, pre-drill and fasten using
at least two staples or nails. Apply a trim board over the
shingles to conceal the fasteners.
