![]() ![]() (for some reason the attachment comes out upside down so I posted it 2 ways.they're both the same image. Now looking at my drawing, can I consider the span to begin where the new rafter is fastened to the existing top chord, rather than beginning at the wall? In other words, does nailing the rafter to the chord count as support? If so I can go out to an overall width of 12' for the lean to while not overloading the rafter. Other considerations 18 overhangs will be the most bang for your buck and will keep you from having to rip roof panels lengthwise. One goal is to make use of a lot of extra lumber I have, which includes 2圆's for the rafters, so I'd like to push it out to 12', on 24" centers.Īccording to the span charts, the limit of a 24" OC 2圆 is 10'9". While the most typical, common and cost effective roof slope will be 4/12, I personally like the looks of steeper roof slopes with steel roofing. It will eventually be enclosed but will not have ceiling or insulation. Length will be 54' long and as wide as I can make it in the space we have. Typically, the recommended spacing for metal roof purlins is 3 inches to 4 inches on-center. The new roof will slide under the existing metal. To keep things simple, I'm planning on sliding the new rafters alongside the chords and resting them on the top row of banding. So what you need to do first is to get the pitch using the following formula: rise run × pitch. The one difference is that we need to calculate the roof rise using the pitch first. Our existing barn is a typical pole barn with 12" eaves and 2圆 top chords on the trusses. The formula used to calculate rafter length from roof pitch is, in fact, the same as the one above.
