Measure the length and width of the carport to determine the area of the roof in square feet.
If you want to calculate these values by hand use the following formulas.
Step 2 determine dead load by identifying the amount of each construction material used in the roof.
Roofs are under a lot of pressure.
Multiply the length by the width to get the measurement for the area.
Rlw is used to calculate the sectional size of some roof members and supporting wall.
This video looks at roof load width rlw.
In order to stay intact and in place a roof must be able to resist loads both permanent and temporary that are pushing.
