Amazing, but expected. When I took ownership of my 1830s row home with pitched roof. I had two estimates, each for 8,000-10,000 to remove the old and install new. That was in 2001. Now you are saying the price is 3x that price. I have not done the work, but had a feeling and am was guessing a new roof will cost $20K, but I now have think of 30-40K. I had a flat roof on another row house, that cost 2K to simply add over extant, but that was in the 1990s.

We are in a new world of inflation, and we have to expect that everything will cost more. Workers deserve decent pay. Roofing is a crap job. Knowing car repair costs are up and many other home repairs too, I hope some of the higher cost is going into the workers pocket mot just owner's profits. Still so many white collar businesses seem to be able to pay their desk jockeys high salaries, they must be soaking their customers.
