Anyone added on a covered patio extension yourself?

A basic lean-to should be pretty easy depending on what you have to work with. Leger board - joist hangers - hurricane ties - purlins - flashing - securement of columns (anchor brackets into cement, set into new concrete with sleeves, etc.) - not in that order lol

I know nothing about standing seam roofs yet.
Should I?

Way overkill for just a patio extension and too difficult to get right. It's definitely the best roof but you could easily mess it up and will need specialty tools.

Put it this way: We have a 100k roll forming machine to run our own standing seam panels and a 12K "robot" to mechanically lock them in. Even I wouldn't do standing seam for my patio extension. Screw down metal is perfectly fine. It's a very nice roof, cheaper, and much easier to install.

Standing seam has no screws drilled into the metal (you use screws for brackets underneath) and is locked in together/sealed by crimping them together.



Screw down metal (99% of what residential houses are) is locked into place/sealed by screwing the two panels together. You see the screws visible from the top off the roof. You can get it in pretty much any color you want, it doesn't have to be galvanized.

You probably have a Metal Mart in your area. You can just give them the measurements you need and they'll cut them to your exact measurements and give you the right amount of screws and trim (if you decide to go trim) you need. Will most likely be cheaper as well.

What area are you in? I'll look and see what places are near you that you could call when you're ready.

Looks like there are a couple metal marts near me. Those panels also dont look very expensive so ty for the tip on those.

Are there any tricks to know about this to improve wind resistance? Would much prefer to avoid seeing the screw down metal panels go flying off the next time a storm comes through…

If it's not a big area, it'd be worth using screws for your decking instead of nails. With your metal, you can put an eave trim on there instead of just having it hang over a lot on the sides. Also, I see people run their metal around a foot over on the end. There's no need to do that, 6" is plenty and less if you're putting gutters on there (6" overhang would basically cover your gutters. And you can just simply put more screws in your metal, on the vertical run. That gives you more potential to leak but as long as you properly screw them in, you wont have to worry about leaking.

Dont forget hurricane straps and tie. A DIY covered patio is a recipe for a flying projectile in Louisiana.

I also dont like 1x4 cross, 2x4 is not that more expensive.

Many thanks to iwyLSUiwy

here are the results

Looks great
