I am planning to build an addition onto a mobile home. What is the desired roof pitch in Missouri if…?
I agree, this is a very interesting topic for discussion and I have a couple of tips for you. If you want to more accurately calculate the size of the roof, it will be much easier for you if you use a special roof pitch calculator. Here is a link to their website concalc.org This is a very good roof pitch calculator that will help you in this matter.
I live in Missouri, own a construction and roofing company, and also Live in a mobile home. There are no rules as to the degrees of slope to the roof. I can’t for the life of me understand why you would want to make the additions roof tie into the peak of your mobile home. I’m assuming that you own your mobile home and the land it’s sitting on. Once you do a room addition like your suggesting, it can hardly be considered a MOBILE home. Do you realize what would be required before the mobile home could be relocated if the addition roof is extended to the peak of the mobile home roof. I would suggest you look into the posibility of a flat roof with a minimum slope of 1/2 inch drop per each foot. And have it covered with EPDM by a quilified applicator or a Modified Bitumen Rubberiod roof. The EPDM is the more expensive of the two but will provide better resistence to the elements including large hail. I also suggest that you have the siding (if vinyl) removed where the room will be attach
