Raising the roof

[TomG]

I would agree with Greg as well. I see Horror Fright sells bottle jacks that lift 19" for $65. A couple of those would easily lift one side. You might have to install a temporary header along the eaves to keep the structure from sagging in the middle when the ends are lifted. A 2 x 6 screwed flat to the underside of the rafters should be adequate, although it sounds like you might be doing something like that already.

As someone who spent the second part of their career "making a living" in the pharmaceutical industry, I would like to point out that there are a lot of factors that affect the cost of drugs, but the primary factor is the years of recurring engineering it takes to develop a new drug in an industry hampered by government regulation. Look how much the cost of a drug drops when a generic equivalent becomes available. It doesn't cost much to make them, but it costs a heck of a lot to develop them. Our niche in the industry was to build instruments to eliminate poor candidates for new drugs before a lot of development money was spent on them, doing our part to reduce the cost of drugs.
