Instructions to match a new roof to an existing roof

     

1. Overall span is measured from out to out of stud wall

2. Overall height at the ridge is needed to determine roof slope. This dimension is to the underside of the roof sheathing.

3. The vertical heel height above the wall is needed to compensate for different framing methods. Measure from top of wall to underside of sheathing.

4. Give dimensions to both sides of ridge. This is to verify that the ridge is at center of span.

5. Take all measurements to within 1/8" if possible.
