The composition shingles on my 14 year old house need to be replaced. Is it
necessary to remove the old shingles first, or can the new ones be installed
over the old ones?
Thanks

It's possible and a lot are done that way to save some money, but it's a
foolish shortcut imo...
Why would you want to put a costly new material over old, failing
material, causing almost certainly, a shorter lifetime of the new
material you just spent good $$ for? Never make a lick of sense to me,
but it's your roof...

This is Turtle
Yes you can lay over old shingles but most people don't because of weight of
them on the roof and some people in the roofing business say it will damage the
new shingles in someway.
One ideal of this is the next time you recarpet you living room, lay the new
carpet over the old and would you like it done that a way ?

you can have 3 layers of roofing. after this you must do a "tear off",
remove all roofing and start fresh

They say you can put up to 3 layers on a roof but why as another poster
stated!
