There is no minimum amount of square feet that you lift. However, for economic efficiency, it becomes impractical in most cases to lift a roof that is less than 2,000 SF. However, this is not to say that our company has not lifted smaller roofs. In some instances, a small section of a larger roof must have a higher clear height in order to accommodate new equipment or processes. In these instances, raising a portion of the existing roof is much faster, cleaner, and less costly than demolishing a small section and rebuilding it higher.
