I want to make this one big masterbed , maybe put a half bath in there. I was thinking about a big master bath , but we really don't need that I suppose .

So the plan is once the heating season is over I demo the interior and roof , leaving only the exterior walls. Then set trusses , roof , and I have the summer to drywall/wire/paint ect. I was thinking about building 2x4 walls over the existing ones for 2x the insulation.

If you add the walls inside then you could add to the existing walls to make them full height, that wiyulkd make the stiff enough.. Except you have to be carefull, if you don't end up raising the other roof, you don't want the inlaw roof to be high than the house and that may be why it is lower, in that case, I would look at sissor trusses and leave the wall height alone. The truss company would want to know how thick your walls are for sissor trusses.
I guess at this point all you can do with the house is draw up the plans, showing the exsisting 2x6 floor and see if they will let you get away with it.
Where I am you wouldn't need a permit to repair the roof on the suite.
In some areas there is a dollar value that a home owner can get a permit for, so you might to do it as unfinished space.

You said you had been doing some beam work, remember to keep in mind where the load is going in the basement. If the origanal wall were only carring the ceiling you may need to double up some floor joist below.

Yea I need a permit . I wouldn't need a permit if it was only shingle work. It's somting like 100$ plus 5$ per 1000 spent so whatever. I haven't touched any load bearing walls in the main structure . Good idea about making the walls higher , haven't thought about that.

Have any advise on how to size beams for load bearing walls? Is like to have a plan set , so when I run it buy an engineer its basically.done and he just has to approve it.

The height difference with the main house would be the only question. As far as sizing beams, above my pay grade. I can find span charts and figure live and dead loads and snow loads but seldem get it right because the engineers are looking at a lot more or should be, they don't like it when you over size the beam too. Didn't make sence to me until he explained, he had required a 5.5" x 9.25" beam and we installed the 5.5" x 12" that the lumber yard delivered. He said some day some engineer will look at that beam and think he can add (X) more weight to it and if someone did that they would be overloading the foundation and footing as they were designed for the smaller beam.

In your basement it looks like everthing up the middle is being carried by some steel and wooden posts. If that is all there is then the walls running the other way upstairs that are bearing the floor above or the floor that you would like to use up there. Then the beam will want to run full distance so the load is landing abaove the foundation wall and the center beam in the basement.

I'm starting to make a material list. As far as gutters go , is there a type that has a flange attached to the gutter that rides up the roof? Then you could ice and water shield over that flange? If not what style do you recommend?

Usually the roofer is up there first, if there is something like that, I have't seen it.
When you have figured your list, add 30 length of 2x4.

You should be able to solve ice damming with ventulation.

Hello all , especially Nealtw! Who has been a huge help and great teacher!

I figured I'd stop back and beg for some more help! So I basically did nothing structural since I last visited. I spent my money on getting natural gas brought in , new hot water tank , new furnace. There were some close calls on getting oil delivered with my driveway and snow , not to mention the sky high prices. Filled 4x at 700$ last winter! So I installed forced air and ductwork . 2 stage variable speed and a direct vent hot water tank. Now I have no need for. Chimneys.

So you might have seen on the news we had a killer snow storm about a month ago. Well it broke my house , lol. I shoveled for 2 days straight on my roof. I'd say I got about 7' of snow. So I had a couple contractors come out and they were kinda lost. As Neal said , I needed a structural engineer. He was out last week.

Unfortunately some rot was found in some joists that broke and insurance is only going to cover a fraction of the damage. My plan is to rip off the second story and rebuild. My engineer at initial inspection believes it won't be a problem. One plus is he is going to let me draw up my as builds to save me a bit of cash. So most work is on hold until I get a set of stamped drawings.

I do have one area , the workshop behind the garage , that I would like to adress now. I'd say half the joists cracked , all bowed if nothing else , alot! I'm worried if that goes it will further damage other areas.

So let's deal with the garage. You wrote joists, did you mean rafters?
2x4, 2x6 ?
length?
sitting on solid walls that sit on foundation or?
