Planning ahead is essential since finding things out the hard way is usually more expensive in the long run. When contracting work, the most important function is getting the bid right the first time. If you don't get the takeoff right, you're likely to lose money. This situation was the case for one roofing contractor whose lack of adequate materials led to damaging mold growth in a condo complex. Unfortunately, mistakes like this can potentially cause more damage than the project is worth. With emerging data-enabled solutions such as aerial roof measurement and digital estimating platforms, contractors can now use technology to bid on construction projects more accurately every time.
