Have the Roof Designs Examined. Some designs will not use roof joists. They use other means to distribute the weight by using other structural points. Prior to adding or removing a roof joist, always make sure the plans are properly made.
Proper Distance. A roof joist is always spaced no more than 16-inches apart from another roof joist. If the roof is not completely square, you can decrease the space between joists but never increase the space.
Measure from the Ends. When starting to space out the roof joists, always start at the end of the roof. Install a roof joist at each corner of the roof and then from these, you measure the distance for the next roof joist and so on until they all are in place.
Double Check Everything. This should go without saying but always check and recheck the work you are doing and the measurements you are taking. It may not seem like a big deal if something is off by an inch, but it can be.
Roof Joist Materials. Roof joists can be made of wood, metal, concrete or any number of materials. Just because one material may be stronger than another doesn't mean the spacing changes.
