How do I calculate the size of my roof?

Multiply your house length by your house width to get the area. (For example, 40 feet x 30 feet = 1,200 square feet.) Next, multiply the area by your roof’s pitch. (1,200 x 1.05 = 1,260 square feet.) Follow Us for more details Please!

What is the most common roof pitch?

Conventional slope roofs are most common with residential roofs. This means the slope has a pitch between 4/12 and 9/12 on most homes. Roofs with a pitch exceeding 9/12 are called steep slope roofs.

How do you calculate rafter length?

 
 
If you are calculating rafter length from the center of the ridge beam (as shown below), you will need to subtract half of the thickness of the ridge beam from the top end of the rafter. For example, if the ridge beam is 1.5 inches thick, subtract 3/4 of an inch from the overall rafter length.
 
Rafter Dimensions

As roof pitch is lowered, the weight burden on the rafters increases. For low-pitch roofs, building codes may require larger dimension rafters.
 

How far can a 2×6 rafter span without support?

How Far Can a 2×6 Rafter Span? A 2×6 rafter can span 14 feet 8 inches when spaced 16 inches apart with No. 1-grade southern pine lumber on a roof with a 3/12 slope or less with a maximum live load of 20 pounds per square foot and a dead load of 15 psf.
