Just buy a prebuilt roof and have it delivered, a few toe nails and your good to go!

Get an RV awning. Or a carpenter, or a clue. Your choice.

Rip out some of the wall and ceiling drywall and insulation in your house and see how that was framed. Just copy whatever is in the house.

No you don't need any of that stuff, just find yourself an old garage door of the proper size.

Take the one from your neighbor if it looks like it will fit. Then, attach one end to the existing roof and the other end (the one with the metal rod extending form end to end) prop that on two 2 x 4s. Slope it down toward the 2 xs and then tighten the metal rod to straighten it up nicely.

This works great and is quite inexpensive.

I hope this is a help.

just put a post on each corner and one across the top, 2x4 on the bottom is all you need

Well first off, i hope i am not out of line here, the 3-12 pitch isnt alot so i would go with PT 8"X8"s for you supports. You should use a TJI layed on its side for the top plate. Then you want to fill the void of the TJI with LVL's for you top beam. For you rafters i would use TJI's 6"OC to carry any kind of snow load. Now with proper clamping and use of glue you wont need any screws or lags, you would want to just tack everything together until the glue sets. For tieing into the main roof just fire up a saw and cut holes in the roof to allow the TJI's to slip inside but you want to use alot of caulk to prevent any leaks. What are doing for the shingles or tin? I would place tin sideways so any water runoff from the main roof would slow down on the shed, er i mean deck roof or else the water runoff will shoot right off the roof. I hope i have been of some help, lets be safe.

With this system you could also use the roof for a sluice box in case you ever got into placer mining so be sure to put the whole roof on pivots.

I dont know about you but with my luck this guy would hit it big and forget all about us and how we helped him .

I'm curious ...who helped you build the deck?

rwa

that's a great idea but, I really think this guy is a DIYer ... I'd suggest he prefab his roof .... lay his sheathing out on his deck, add the drip edge, felt paper and shingles, use 2 1/2" ring shank nails .... weigh it and let us know how much, then we can tell him how to build the structure

You came to the right place. In a cost saving effort, which yours clearly is, pitch it back towards the house. This way you'll save on excess gutter cost.
