Most roof framing is 24 on center and you can still build sheds up to 14 with 2 4 rafters at 24 on center.

Roof width load.

For light load roofs 24 o c. Roofs are under a lot of pressure. Applicable uniform and concentrated roof loads with the photovoltaic panel system dead loads. This number represents the total load that your roof must carry.

In order to stay intact and in place a roof must be able to resist loads both permanent and temporary that are pushing. Roof live loads need not be applied to the area covered by photovoltaic panels where the clear space between the panels and the roof surface is 24 inches 610 mm or less. For heavy loads 2x4s can span up to 5. The exterior wall and the headers within will carry all loads from the mid point of the house between the supporting walls to the outside of the house including the roof overhang.

This video looks at roof load width rlw. Rlw is used to calculate the sectional size of some roof members and supporting wall. The distance in this case is 12 ft 2 ft 14 ft. Load limits on the roof of a building.

This is the sixth video in the series on the timber framing code. So each lineal foot of wall must carry the loads imposed by a 1 foot wide strip in that 14 ft region. Multiply the load per square foot by the total area of the roof. 2 4 rafters can span up to 7.
