Slanted patio cover DIY help
Posted on 3/30/20 at 11:38 am
Posted on 3/30/20 at 11:38 am
Anyone built a slanted patio cover? Want one end over the roof and gutters slanted down over the patio into the yard. Looking for any advice, plans, lumber recommendations, etc. I would have to bolt it to 4” concrete slab by the house and either bolt it to the patio edge or set in ground..

draw a quick picture of what you are trying to do and post it and I’ll try to help

I would put the addition below your roof eave, but as long as this is a standalone addition and not connected to your house that should work.
you want post and beam assembly.
run a beam between the columns at the low eave and at the high eave.
I would set three columns at the high and the low (making two equal bays)
You can make a glued and screwed beam out of two 2x’s, and notch your columns (4x4 or 4x6) to accept the beams
then, run rafters from beam to beam, using rafter hangers, 2’ on center, then 1x nailers on top of those on 4’ centers. Screw your roof sheets to the nailers. Attach rake trim at the high and let the rain run off of the low

Are you me? I’m planning on doing this exact same thing

What is your opinion on the posts install? Mounted on top of 4” concrete sufficient enough? I’m actually thinking about doing this with almost the same dimensions already have 4” thick concrete already in place.

I have been wanting to do this same thing myself but have been putting it off because mine it a bit more complicated. I don’t want to go above the gutters because rain will overshoot my gutters if it rains hard enough but I don’t want to go below because I’m afraid it will be too low coming off a 9 ft roof line.

Simpson makes a 4x post anchor designed for that.
drill out the anchor hole with a hammer drill and masonry bit and blow it out with an air compressor, set the anchor bolt in epoxy and also smear some epoxy under the plate. After it’s set you can place the column in the anchor assembly and fasten it to the plate, braced to be plumb and level
the whole assembly will stiffen up once you install the beams and rafters just keep moving and adjusting braces to stay square

I see no problem going over the roof line giving you more open head space

That’s what I’m planning on doing. Is there any way to put a “bigger/better” gutter on the house to really make sure that runoff doesn’t get on the patio?

OP, is there a drop off from the doorway of the house to the patio slab?
I wouldn't go that way at all. It is best to just tie the rafters into the top plate of the wall. Just remember that you want no less then a 6" drop from the wall of the house to the end of the patio roofing. I will get you some pictures of what I am talking about.
Took the pictures and sent to my email, but for some reason yahoo is not loading.
Sent again, set the same.

There is a about a 3” drop from doorway to slab.

I built almost this exact same thing for my in-laws. They have an older ranch style house so going under wasn’t an option due to height. AlsoX their roof doesn’t have a steep slope so no issues with water coming over from the roof. There is enough space to where if there’s a driving rain, it will come through the gap. It’s fixable with a vertical barrier but I haven’t done it yet.
Will snap some pics and send over.

Tried to send the pictures again. Got to be ATT screwing up.
OP, how high is it from the patio slab to the eves of your house and how wide is your eves?

We used 8x8 primary support beams, 4x4 support across the back, 2x8 for the joists across the top and faux bamboo sticks for the shade up top and down the back. We spent the most time sanding down the wood/bamboo and staining it to the color we want. Here is the design we use for influence, although ours is not nearly this fancy. It took us 3 full days from start to finish, with a large portion of that being the drying time for the vertical supports.

I wanted to bump this thread as I may do something similar soon. I wanted to see why you wouldn't just remove a section of gutter and attach a ledger to your fascia? Also do you not need concrete footers under the slab for the posts?

Wow, it seems everyone wants to do this. Me included. The only way the boss lady will allow me to cover the back deck is if I don't attach it to the house. The deck is a floating deck that just happens to touch the house We have a new roof and she will not let me touch it. 
She also wants me to deck and shingle it to match the house. That's why it is way down the list of action items for the back yard.
It would go over a 16x16 deck so the roof itself would be 20x20 with a 2' overhang from the upper and lower beam. I'm just not sure how big the stringers, beams, and posts would have to be to support something like that. I'm guessing that I would want to run a post and beam in the middle to keep the lumber size reasonable. Although I THINK I could get away with 2x8's 16" on center. Any thoughts would be much appreciated.

Why not just tie into the house?

Don't tie in there. You remove the fascia and black out board behind it and slip your roof rafters up and sit them on the wall top plate.
OP, I forgot about this thread.
I have 9' ceilings. The patio slab is a 6" drop down. That gave me 9 1/2'. I has a 6" of 8" drop. Can't remember. But even with a 8' ceiling and going out 14', one can get away with a 6" drop which is still good. That will still give you a 7 1/2' ceiling finish height.
Oh, my patio cover has a walk way covered to my carport area. I had to set the patio roof drop to match out the walk way roof that ties into the carport.
