kindly share it with me.

Ask the roofers bidding on the job. *If any say they can cover the old
roof, ask the cost difference for a tear-off.
Always have 4-5 bids on the job unless you know it yourself.
Don't know if the roofer population supports that where you live.
Nobody here can see your roof.
Personally, an extra few hundred bucks for a tear-off is worth it to
me.

I agree it's a good idea and I would do the tear-off.
But it's more like $1000+ for the an average home.
Just the cost of the disposal of the old shingles, typically a
dumpster, is a few hundred bucks. The you have all the
labor. And on top of that, beside
what they quote you, roofing contracts have a charge of about
$50 a sheet for any plywood replacement. Without a tear-off,
that won't happen. With it, good chance they will find a couple
sheets that need to be replaced, depending on the age of the
house and that gets added at the end.





*The roofer can see and replace any rotted boards/sheets, and the
new shingles will lay better and look better. *Have him put in a new
roof fan if you have one.
