Topic tags/keywords: question patio

I am going to be building an gable roof open structure over my patio outside. Right now i have a 14×17 slab. Im wanting to expand it to roughly 17×20. I just have a few questions on materials so i can price materials at this point. Would 6×6 pt’d post suffice. (This will be free standing but close to the house)

For the roof structure would 2×6 framing lumber work? I could use pt’d lumber on the outside.

What are people using on the roof ? Osb or plywood?

Does anybody have a picture or a link of just a basic gable roof structure with open sides? I have been looking all over google and all i can find is structures that are decorative not really what im looking for. Thanks

Yes, I think bot sizes are appropriate

You could build this structure using pole barn construction. Pole barn construction the Pole is the foundation you bury a 6×6 pt post 4’ in the ground and you build the rest of the structure off the posts. Here are some pictures of my shop that I built using this construction technique.!

Brantley, I think 6×6 posts should be fine for this sized structure, but something for you to consider is to laminate 3 PT 2×6s together using 20d nails. Cut them 3 different lengths to get them 12” above ground level, say 12”, 24” and 36” offset. Then do the same with 3 regular 2×6s so they interlock with the PT pieces to get the total length you require. I know that I am not describing this well, but hopefully you will understand. The benefit is that you are using that much less expensive PT lumber and by laminating 3 pieces together you will have all the strength you need. I did this once for pole barn construction and it worked fine. HTH

We bought plans here:

Here is the first stage connect to the roof of the house:

Used 6×6 corner posts and 4×4 on sides

We used 2×6 rafters on beam constructed from 3 – 2×12 Douglas Fir

Used plywood for the roof

Completed framing

Screen installed and ready for relaxation

I used OSB on my rood. I wish I sprung the extra cash for plywood.

I don’t know how anyone can answer your questions without seeing a plan. We don’t know the length of the joist span or how far apart your posts will be.

Have your say...
