My church is involved with adding onto a storage shed that is in the back of a homeless shelter. Existing shed has a gambrel roof with ridge running parallel to the addition. The old structure is 14′ wide by 18′ long. Additon is full length of old building and adds ten feet. I think roof on addition should be a gambrel, with new ridge centered on total sructure width (24 feet). This would entail extending top of existing gambrel roof toward the addition by about five feet. I then propose doing mirror image of that roof to make the new half of the roof. Then the whole roof will still be a gambrel, but the top two slopes (the shallow slopes that come off the ridge) will be deeper than the lower, steeper slopes, but the whole roof will be symetrical.
Sorry, I cannot do photos or drawings.
The guy who is in charge wants to just build a new shed roof in one slope (slightly less than 4/12) from the outer wall of the addition up to the existing top ridge . I think this will look bad.
I also propose keeping the old roof and framing over it and using gussets where the slope changes, and at ridge. They are proposing stripping off old roof to expose rafters and tying into those, as well as building knee walls to support where slopes change (making structural ridge(es). I think with a crew that is here today, gone tomorrow and with all the storms we’ve been having, leaving the old roof on as much and as long as possible is a better way. Existing building is used to store and sell used clothing.
Is there something I’m missing? We are using old, recycled lumber for rafters, but have to get new sheathing and shingles. Labor is free (and worth every penny).

Heres an elevation view of your proposed addition. I'd probably pass on working on it LOL!

Thanks for the drawing--that's exactly what they want to do. (Wish I could draw on your drawing!) I want to extend the second slope of the roof on the left side of your drawing until reaches the midpoint of the wall, then build a mirror image of the left roof to make the right side, so I still have a gambrel roof.
This guy was at least somewhat receptive to my ideas. We din't have a chop saw on site, so I showed the guy how to cut by holding the shoe of the circular saw against a speed square--he was just eyeballing the cuts, which works, but I think a speed square makes it faster. I was handling the sheets of OSB by myself and putting two nails near top to hang (we put OSB on the inside) so I could put the panel up and nail it by myself. Other guys had two men to put the panel up and one held it while the other nailed it. Since we were using old material, none was the 88" length that we needed, so I proposed running the pieces horizontally and they agreed to that. Wish we had a compressor and nail guns!
Is your project done or do you still have the opportunity to do it right? You can draw on the picture. Hit cnrl/PrtSC with the picture showing. Open up Paint. Hit ctrl/V. You will then be able to use the Paint program to draw on it. SaveAs the new drawing as a jpg and you can repost it here. Bob's next test date: 12/10/07

I doubt that it's done--the guy is having trouble getting help and I had to work on my real job today--ripping out T&G oak flooring in a kitchen (which is under the cuboards) and then had linoleum and 1/4" plywood and then vinyl on top. May have missed a layer or two of other sheet goods. My back is sore from running the wrecking bar alll day. (And chiseling out the boards in the toe kick--guy I work with has (had) a nice flush cut power saw, but he broke the drive post today.)
I couldn't seem to open your drawing to play with it, but I did print it and I'll draw oon it and photogragh it and try to post that! Simple. Welcome to my life.
Ever get what oyu want and then not want it--guy called me and said he talked to the other "designer" and that guy said he was thinking the same thing as I had. So we could do it, but then the chief said he had planned for us to frame the new roof as a regular gable roof and run the ridge into the old one at right angles. Well, to my way of thinking, that would be a lot better and easier. Have to strip off old shingles because they are covered with mosas and they're afraid to contaminate things by closing them in the building. So, back to the drawing board--except he already has his plan drawn up.
Anyway, I did a drawing of my idea on the printout of your drawing and photographed it and it is attached--very blurry, but I'm hoping you can get the idea.
I could just barely see what you were doing but I understand. When you are done, it will look like a normal gambrel roof. Bob's next test date: 12/10/07

Right. Met with the guy today and we agreed to do it his way--new gambrel roof intersecting old at 90 degrees. (Turns out it was another guy's spur of the moment idea to frame the new roof as a shed, because he likes to do things the easy way!)
Meet at 10 tomorrow to frame a test truss to see if it'll work and so on. Then I go to my "real" (paying) job and touch up paint--why the customer and the "boss" have to paint and then tear up the floor and then tile, is beyond me--sure gives me lots of touch up to do!
