More Shed Questions...

???? 16 foot rafters would result in a building about 28 feet wide. In planning buildings, I have usually taken the approximate size and fine tuned it to match standard lumber sizes.

My bad- I assumed one had a saw and math skills and the ability to use both.

So a 4/12 gable roof on a 14’ wide building with 4-6” eaves is a little under an 8’ rafter (16’ cut in half). A shed or flat roof with 1’ or under eves on a 14’ building would also take a 16’ rafter.

But if one wanted a gable roof but didn’t want to cut 16’ boards in half then a 28-29’ wide building would be ideal- you do have a point there.

Here is some additional detail on my Rafter Design. I mentioned a 16' rafter... I intended that to be the full width of the building.



Using the full length 16' ceiling joist with a 6/12 pitch will allow me to use 10' rafter boards. All good with little wasted cut-offs.

I would increase the strength of your rafter by making it into a truss. A simple M design will give you tremendous strength and its super easy to do yourself.

I know, that shed guy again... humor me for a few more questions.

So I was thinking about a 14 x 20 shed and stared to design and price out lumber. This will be a stick build 2x4 walls with rafters made from 2x6. I plan to use collar ties on every rafter and a ceiling joist on every other. They will be spaced at 24' OC.

Sorry, you lost me at 14x20 shed stick built with 2x4 walls and 2x6 rafters spaced 24" OC. I have a 12x18 shed built with 2x6 walls and a 6 pitch roof using 2x8 rafters, all 16" OC. Do I overbuild? Probably, but we also get a lot of snow load on our roofs and I never have to worry about the shed roof.

2x6 walls also give a nice advantage of being able to build in shelves between the studs to put all of those shed-like items like cans of WD-40 or partial quart bottles of oil for the lawnmower. I also have turned some wall bays into storage for things like plow stakes for the driveway or long handled yard tools.

My shed is built on 6 sono tubes with bigfoot bases. The floor is framed with doubled 2x8's 16" OC and 2x6 as decking, all PT. Wanted to be able to park the 800 lb Harley in the center of the floor and not have it feel like it was going to fall through. I also have an 8' wide, 7' tall garage door on the end for easy access, with a garage door opener of course.
