Ooops, sorry I plan on have a straight gable roof on the storage building. Not for sure if I need to use 2x4's, or 2x6's for the 10 ft span. Mack0333

Almost forgot, I like the look of a 7 / 12 style roof.


OK, gotta pick just one, 3 ft rise or 7/12. A 3 ft rise is closer to a 5/12 pitch
Darn it, sorry I like the 7/12 style.

My storage building will be 10' wide, by 14' long. I was hope not to have to by pre-made rafters?

You need to tell us what type of roof you want. Hip, gambrel, gabel, flat sloped??

To help you in your post I posted the terminology to express roof truss.

OK, 14' wide with one ridge down the middle running 14. That makes each side of the peak 10' plus any overhang, probably at least 1' each side. (this is going to be like a math lesson) Draw a line 11" long and figure the equation 7 is to 12 as X is to 11. Answer, your height is 6.4'. This means you must create a center post to hold your ridge beam up to 6.4" and there is a ridge support at each end of the building. Before I go too much further I should mention you can call Menards, Home Depot or Lowe's and get a price for trusses. Maybe you should do that before we get too far down the road. Stick building isn't always a beginners forte

Hi Ball

If he wants shed to be 10' by 14', then ridge would be set at 5'.

A 7/12 pitch would give him 35'' rise.

Use 2x6 for rafters and collar ties 2x4. Set ties at 12'' from ridge.

creahands, I punched in the wrong calc and just never questioned myself. I was figuring 14' wide instead of 10'. Counting on 1' overhang I came up with 3.5'. Did you miss a decimal or no consider the overhang, our ansers are to close so maybe I made another over sight.

Ok guys my apologies, I should have given all the info on this building. The storage building will be 10 wide x 14 long, with 6' side walls and a straight gable roof. I have build other things but rafters don't seem to be that hard once I get the basics figured out. I will have a 6" overhang on the side, with 12" on the front and rear. I was hoping to use a 2x6x12 cut in half to make both sides. Am I totally off kelter with this thinking?

On a 14' span the ridge would be set at 49'' (7' run times 7'' rise). The overhang is not part of equation. Measurement is from top of plate. The tail piece (overhang) can be any length u want and does not change pitch.

Your measurement, 3.5' (42") would be a 6/12 pitch on a 14' span.

Isn't his span 10'? Length of building is 14'

Mack, you do not open a new post every time you want to add something, it just confuses everyone. If you go back to your original post you will see new answers and questions have been added. https://www.askmehelpdesk.com/construction/figuring-rafters-10-x-14-stotage-building-355601.html

Yes it is 10' span. I was just showing how u got the 42'' rise.

Also the ridge board should be 2x8x18' so the roof can overhang front and back of shed. U will also need cripples between end rafters and next rafters in.

Chuck

Thanks Chuck, I was so off with my first calc it was laughable.

Isn't his span 10'? length of building is 14'

Yes the span of my building will be 10' wide.

Yes

Yes span is 10 wide.

I am preparing to build a 10 x 14 storage building, I would like to have a 3ft rise but not sure on how to proceed, and how to make all necessary cuts.

First answer: To make the cuts use a simple speed square and mark the board on a 7 common for the top cut.

I plan on have a straight gable roof on the storage building. Not for sure if I need to use 2x4's, or 2x6's for the 10 ft span.

Second answer: 2x4s are fine. Your run will be 5' feet.

Almost forgot, I like the look of a 7 / 12 style roof

Third answer: To get the rafter length for a 7/12 pitch multiply your run (half the span) 5'X13.89=69.45" inches or thats 5' 9-7/16"

Fourth answer: 2X6 ridge is more than enough with 2X4 rafters.
