How do figure how many rafters it take for a house?
The question must 1st be asked is "what spacing do you plan to use?" Local codes will apply of course. Up North spacing is closer than that of the South because of snow loads. 16 inches on center is a good number to use. You said rafters but I wonder if you meant trusses. Another problem with answering the question is the roof design. For a ranch style house you would simply multiply the length in feet by 3 and then divide that by 4 and add one for the end this will give you the number of trusses you need. For rafters you need to multiply your number by 2 and add 4 for the barge rafters.
