STEP 29: ROOF STARTERS
1: PLACE THE 1 X 4 X 47-1/2" GROOVE-ONLY ROOF STARTER BOARDS AT THE PEAK OF THE ROOF. THE HOLES IN THE
ROOF STARTERS SHOULD BE APPROXIMATELY CENTERED (SEE BELOW) ON THE ROOF SUPPORTS, AND THE FLAT
ENDS OF THE ROOF STARTERS SHOULD BE PLACED AS CLOSE TO EACH OTHER AS POSSIBLE WITHOUT THE BOARDS
OVERLAPPING.
2: FASTEN THE ROOF STARTER BOARDS TO THE ROOF SUPPORTS WITH #8 X 1-1/2" WOOD SCREWS.
MEASURE DIM A ACROSS THE BOTTOM OF THE ROOF SUPPORTS NEAR THE CORNER POSTS. WHEN ATTACHING THE
ROOF STARTERS DIM B AT THE ROOF PEAK SHOULD MATCH DIM A. THIS WILL MAKE THE ROOF SUPPORTS PARALLEL
TO EACH OTHER. DUE TO WOOD MILLING VARIATIONS YOUR HOLES IN THE ROOF STARTERS WILL EITHER BE
CENTERED ON THE ROOF SUPPORTS OR THEY WILL BE OFFSET TOWARDS THE INSIDE OF THE ROOF SUPPORTS
SLIGHTLY. SUBTRACT DIM A FROM 47-1/2" AND THEN DIVIDE THIS NUMBER BY 2. THIS WILL GIVE YOU THE
OVERHANG FOR EACH SIDE. USE THE OVERHANG NUMBER ON EACH SIDE TO KEEP YOUR ROOF SUPPORTS
PARALLEL.
