Sujet: Accurate Roofing Material Takeoff for Residential Projects

I want to discuss how important it is to do accurate roofing material takeoff for residential jobs. In my experience, even small mistakes in measurement or calculation can make a big difference in cost. A construction estimating company can help avoid waste and make sure the contractor has the right amount of material. I am interested to know how others handle roofing takeoffs. Do you use software, manual methods, or hire professionals?
