My complete roof will need to be replaced in the next few years….meaning rafters, sheathing, and all. So I was thinking of raising the pitch a little bit to make some living space up there. Its tall enough that I can stand in the middle wit about 4” over my head and I am 6’ tall. I believe the pitch now is 7/12 or 6/12, I have not really measured it. Would raising it to 8/12 be enough to have some living space? The house is about 26’ deep. Also for the floor to be stable what should the ceiling/floor joists be in size?

Cost to benefit ratio.

What is your cost to benefit ratio? Will it increase your property value enough to justify demolishing then re constructing the entire roof system to add just a few inches?

In most cases: Hardly.

You would do much better to add a full second stroy than tinker with adding a few extra inches of 'head room'.

Will your codes allow it?

Minimum modern headroom requirements are at least 6'8" and more like 7'+ in most instances.

Adding a few inches for headroom may not even be legal where you live.

Can you modify your attic without making major structural changes?

In most cases NO.

Once you begin to modify an existing attic you need to conform to modern codes. This could involve increasing the depth of existing floor joists which almost always requires the replacement of any steps or stairs leading to the attic.

Attic conversions are rarely easy and even more rarely cheap.

THINK before you act and get your local building code officer's input before you do anything else.

you might also consider lifting a section of the roof and building a large dormer w/new kneewall. which would also allow for windows. Again, like the previous response, check w/ local codes for pitch requirements.
