Rlw is used to calculate the sectional size of some roof members and supporting wall.
Measure the length and width of the carport to determine the area of the roof in square feet.
If you can t measure along the top chord divide the span horizontally from plate to plate by 2 then with a scientific calculator divide by cos cosine and then the pitch of the roof.
