Step 33
Install Dormer Siding
1. Cut (2) two 72" long 1x4 boards to length and install across the bottom of the dormer rafters
(see Step 35 for larger detail). Use 8d galvanized box nails.
2. Install (3) three 33-3/4" high siding panels on the front and back dormer walls using 8d
galvanized box nails spaced 8" apart. Important: Paint the bottom edge of the siding.
NOTE: If you are installing a meal roof, trim 1" off the bottom edge of the siding panels
to allow more space between the top of the roof panels and bottom of the siding.
Install Finish Roof Covering - Owner Supplied
Install shingles according to the instructions on the wrapper. This roof design is more complex
than a straight roof and requires flashing to be installed. You may want to consider hiring a
professional roofer who has the necessary equipment to install the finish roof covering.
Step Flashing
1. Install metal roof edging on the perimeter
of the roof area. If you are not installing
shingles at this time, you can purchase
felt paper to protect the roof sheathing.
Install the felt paper before you install the
metal roof edge.
2. Interlace step flashing along the side of
the dormer walls as you install shingles.
Building Tip: Install ridge vent in lieu of
shingles caps. Ridge vent provides ideal
ventilation, preventing heat and moisture build-
up from damaging your building or its contents.
