Does this roofing est of $100k seem right?

[Chris F.]

Hi,

First time getting roof repairs done, the house was built in 1924, had a roof replaced in 2005 but has leaks currently (we think.)

I had a roofing company come out and estimate the cost to repair/replace the roof, immediately the salesperson started stating that the roof was incorrectly installed and that he could see there were three layers (cedar shake, then some asphalt, and finally the current top we can see)

He said regardless of what we do; we have to pull it back, lay plywood down and then put the new roof on and that there is about $70k of work. Finally, the top we wanted to put on was about $27k (it is a "higher-end" finish).

Also note: this is a pointy Tudor house, so the roof has a steep pitch.

I am getting other quotes this week, but for a house of this age given the information I have provided, does this seem right?

Thanks,
Chris.
