How Accurate Roofing Estimating Services Help Contractors Win More Bids

I want to ask about roofing estimating services because I see many contractors are now using them to save time and get more accurate bids. These services help with material takeoffs, labor cost and overall project planning, so mistakes can be reduced. I found one website that talks about this, but I also want to know from other roofers, do you use roof takeoffs or do you make estimates yourself? Also, how much do you think technology like aerial images or software has changed the way we prepare estimates for roofing jobs? I think sharing experiences will help all of us improve our work and win more projects.
