What is the maximum height a roof can be lifted?
Most commercial and industrial roofs do not exceed clear heights of 45 feet. That is not to say, however, that lifting is limited to that height. ROOFLIFTERS has lifted structures as high as 72 feet.
Is the lifting height limited to twice the existing column lengths?
Absolutely not. The ROOFLIFTERS process is specifically designed to address this concern. Lifting can be more than double or even triple the existing height since we do not rely on column sleeves.
