Raising the roof on a split level home

I want to build a 2 story reverse gable room addition in our backyard, but because our home is a split level, the roof heights do not match up to be able to add on. How much would it cost to raise the existing roof over one section 1/2 story high to make the roof height match? I don't plan to use this for living space, just maybe attic storage as it will still be much less than a full story tall. My section of roof I want to raise is 18 feet wide x 26 feet deep. Also, I live in Ohio if that helps.

I am going to talk as if the new reverse gable is at the "front" of the house, and the "back" as referenced below is the long side o the house without the addition.

That seems like a terrible amount of money to spend for no additional square footage - why not just tie the gable roof into the existing house roof:

If lower (as I suspect you mean it will be, with a one-story addition), then the gable roof just ties into the field of the existing roof - a very common feature, like the lower two house pictures in this ad -

Here is what the framing into the roof looks like typically -

In the extreme case, a one story addition on the eave side of a two story house, it ends up looking like a gabled or shed porch roof like this and may not even touch the original roof -


If the addition were say true two-story from ground level so the ridge is higher than the existing roof peak, you can overframe or back-slope the junction like this -

or have a vertical back wall on the gable at the existing ridge line (commonly with loft and triangular bay window looking toward "back" of house), or even extend the reverse gable past the existing ridgeline as a dormer onthe back side of the house, or double-reverse gable it so the reverse gable goes over the existing ridge at whatever height it comes in at, then become a reverse gable roof for a new attic room on the back side of the house.

I would say if you want to raise the roof, thenn do it so the entire attic becomes living space so you at least get something for your money - otherwise talk to Architect on options for tying the roof in, or going with a different roof / addition design, because with your plan you are probably talking $20,000 range plus or minus that gains you nothing beneficial unless you are committ and multi-dormered houses being more common.
