| Determine Your Roof Pitch: |
 |
Nail two boards together at one end. Lay the
boards along each side of the peak of the roof letting them
intersect at the peak as shown. Mark pencil lines along the
boards where they cross each other or hold the angle firm
with a C clamp. |
| Mark The Cupola Base: |
 |
Draw a vertical centerline
on the two opposite sides of the cupola base. After
checking carefully to be sure you have not changed
the angle, lay the board across the base. They must meet
at the lower corners of the base, and also at
the centerline where
they cross, as shown. Draw the cutting line on the
base and cut out from each corner of the centerline.
When both opposite ends
have been cut, the cupola is ready to install. |
 |
| Prepare Your Roof: |
Decorative Purposes-
Cut and remove the portion of
your ridge cap that would normally be under the cupola.
This allows the cupola to fit more
snugly against the roof between the two cut ends
of the ridge cap. If your cupola is for decoration only
your roof is ready for the
cupola.
Ventilation Purposes-
If your cupola is to be used
for ventilation cut a hole in the roof along the
peak six inches smaller than the width
of the cupola. Shingles and sheating only. Do
not cut ridge or rafters. Then cut down each side from
the peak, maintaining a three inch border minimum inside
the cupola base. |
 |
| Install Your Cupola: |
Set the cupola in place on the roof. Be sure that it
is sitting level. Drill holes at least three inches from the corners
(see drawing) in both of the uncut sides of the cupola base. Fasten
the cupola to the roof with #10 or #12 wood screws of sufficient length
to penetrate the roof boards. Caulk where the roof and the base meet
on the angle sides only. Fill the screw holes and apply one or two
coats of good latex or oil base house paint.
