Here’s how you determine your regular style carport’s clearance. Begin with the height of the legs. The standard pitch of the roof is 3/12. That translates to the roof rising three feet with every 12 feet of width. Think of this as roughly the same as a ¼ pitch. That would mean that you go up one foot for every four feet you move to the side. There is close to nine inches of space from the top of the legs to the spot where the roof starts to slope. This is for a regular style structure. Let’s look at this thinking of an 18 foot wide regular style carport with 6 foot high legs.
Here is how you measure the clearance. Look at the leg height of 6 feet, and add the nine inches to the roof where it begins its slope. This puts us at 6 feet 9 inches. Then start moving toward the peak of the roof. This is in the center of the building. Count four feet in, and go up one foot. Four feet inward you should have a clearance of 7 feet, 9 inches. Keep doing this until you finally reach the peak of the building. For our example, it’s nine feet from a leg to the peak. That the rise will be two feet, four inches. You also have to add the original nine inches from the leg, in addition to the leg height. All together, the peak will have a clearance of about 9 feet, 2 inches. Don’t forget to take the top brace into account. This is going to bring the peak down a few inches. If you have questions, our friendly team of experts is here to help.
