Need some advice. Building a shed with a single slope roof. Want 5 bays for boat, tractor, travel trailer and two spares. Largest item is the travel trailer which is 33.5' long x 11.5' tall w/ AC x 8' wide. How long should I make shed? How wide should I make shed? How high should I make shed at front and back? Thanks!

40'x50'
12'6' back clearance
13' 6'front clearance

the drop needs to be about 1' for each 20 feet of length ---------- keep in mind you will need to clear light bulbs in the ceiling and whatever else------- I have never heard ANYONE complain that their garage was too big and they wish they had built it smaller. .

Most semi-trailers are around 13'6". If you think you might ever need to put one under it (like a load of hay) you could plan accordingly. If you don't use some of those items very often, you could go longer and put the tractor and boat in the same bay. Might also be nice if one bay was a pull-through. Go 17' at the front, 15' at the back (would allow for door hardware, see pic), 50'x40' with 4 10' bays.

That pretty flat. Especially in north tx where you can get ice

Great advice. Thank you all!

a Mueller 40x60, 16 ft eaves with 14x14 roll up door is about $17,000.00

Yes it is, typically the minimum slope for a metal roof is 1/12, 1in of rise per 12in of run. So if you had a 40' wide single slope roof it would be 40inches lower on one side than the other.

So at 40' wide with the back at 12' 6", the front would be 40" or 3' 4" higher making it 15' 10". Correct?

Yep thats correct.

Big. Bigger than you think. Trust me.

A 3 & 12 pitch would be the lowest pitch I would do. If building is 36 ft wide take half 18 ft times 3 the peak is 54" taller, roof style like photo by Quitshootinyougbucks. If doing a shed roof slope only one way I would still use the 3/12 pitch minimum. JMO

I would do something similar to this, but with heavier material.

Good advice

Great advice! Thanks!
