Complete Tear-off Or Integrate?

Thank you for this site--a great resource for consumers like me who barely learned what flashing is (at least when it comes to roofing).
We're buying a home in northern Utah built 1987. Within the last few years, a 2-door garage/bonus room and seven dormers were added. While the new shingle looks great, the older part of house is missing shingles from wind or heat damage. There is currently one layer across entire home.
From reading through several posts on this site, I'm getting the general idea that tear-offs are better than adding a new layer of shingles. I'm wondering:
* Can we tear-off only the old shingles, replace underlayment and integrate with new addition roofing that are only a few years old? or is a complete tear-off with all new roof preferable?
* Maybe this affects your answer: the inspector said the dormers may not have been flashed correctly (five of the seven dormers are on old part of roof) and that the roof needs more venilation.
Priority #1: Doing it right.
Coming in a close second: Not spending more $$ than necessary. Thanks for your advice.

Well tear it off. Doing it right is every consumers thoughts. Dont let a few hundred bucks get in the way of getting the job done correctly. In other words intending doing it right and getting it done right are different. When the addition is going to be done my best advise is tear off then and get it done all at once. If not shingles will never match.

It is possible to remove the older shingles and leave the newer ones up.
I would do the whole thing in order to put it all on the same clock if you catch my drift. Your roofs should stay in the same time zone. . Also concider the damage that happens to the newer shingles during removal of the older ones. Your shingle colors won't match up because they would be from different lots. Installing shingles from different lots is something that the material manufacturer urges not to do.
I have done this before, we here in Missouri call it a tie in. When I have done tie ins the shingles seem to not line up correctly even when lines are struck. I would imagine even with g-tape ( ) it would be difficult to line them up the same. The shingle tabs on the roof that stay up there usually don't seal correctly after they have been sealed and then seperated.
Would be the best idea to do the whole thing at once. However still your option. Good luck in what ever decision you make, and I hope it all works out for you and your home.
