Roof Width Load

This is the sixth video in the series on the timber framing code.

Roof width load.

If an example roof is 10 feet by 20 feet the total area is 200 square feet. For light load roofs 24 o c. Multiplied by 40 pounds per square foot equals 8 000 pounds. Roofs are under a lot of pressure.

In order to stay intact and in place a roof must be able to resist loads both permanent and temporary that are pushing. This number represents the total load that your roof must carry. Applicable uniform and concentrated roof loads with the photovoltaic panel system dead loads. Multiply the load per square foot by the total area of the roof.

Rlw is used to calculate the sectional size of some roof members and supporting wall. 2 4 rafters can span up to 7. The distance in this case is 12 ft 2 ft 14 ft. 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.

This video looks at roof load width rlw. Most roof framing is 24 on center and you can still build sheds up to 14 with 2 4 rafters at 24 on center. Load limits on the roof of a building. So each lineal foot of wall must carry the loads imposed by a 1 foot wide strip in that 14 ft region.
