If you intend to insulate the roof, drill 2"
holes between the dormer trusses and
install the round soffit vents provided in
the kit. You also need to drill (2) two 2"
holes in the soffit area located below the
gambrel trusses and install round soffit
vents. Drill (2) two holes at each corner
of the building. A hole saw drill bit can
be purchased at any hardware store.
