Example #1 – Determining Sloped Panel Lengths
- Your building is 28 wide with a 4:12 Roof Slope To determine the sloped panel lengths for each side:
FLAT PANEL LENGTH (L) x SLOPE FACTOR = SLOPED PANEL LENGTH (S) 14′-0″ x 1.0541 (4:12 slope) = 14.7574′ or 14′-9″
Example #2 – Determining Hip or Valley Length
- (L) X (SLOPE FACTOR)= S
- (L) X (HIP / VALLEY MULTIPLIER) = H
