Patio Cover Roof Pitch

Newport Solid

The patio cover has a pitch, this allows rain water or melting snow to flow down to the built in gutter system and downspouts. Slope is a ratio of inches per foot, the minimum slope is 1/4" per foot and the maximum slope is 1" per foot, the maximum slope is the most the cover can be pitched and the roof panels maintain a proper contact with the hanger and beam.

Pergola Lattice covers do not have a minimum pitch, they can be flat, however the Maximum slope is 1" per foot.

To calculate your overall roof rise or fall multiply the roof slope by the entire distance from the home to the center of the beam line, see the examples below.

Total roof fall per projection:
6' Projection = 1 1/4" Min. to 5" Max.

7' Projection = 1 1/2" Min. to 6" Max.

8' Projection = 1 3/4" Min. to 7" Max.

9' Projection = 2" Min. to 8" Max.

10' Projection = 2 1/4" Min. to 9" Max.

11' Projection = 2 1/2" Min. to 10" Max.

12' Projection = 2 3/4" Min. to 11" Max.

13' Projection = 3" Min. to 12" Max.

14' Projection = 3 1/4" Min. to 13" Max.

15' Projection = 3 1/2" Min. to 14" Max.

16' Projection = 3 3/4" Min. to 15" Max.

17' Projection = 4" Min. to 16" Max.

18' Projection = 4 1/4" Min. to 17" Max.

19' Projection = 4 1/2" Min. to 18" Max.

20' Projection = 4 3/4" Min. to 19" Max.

Note: Based on drop to beam, beam line is typically set back 1' from the end of the projection.
Tradional patio cover numbers will vary as many applications do not use a setback beam..
