The woodwarped a bit whne it dried out. Using a 6x6 would have stopped that... Or a good #1 select that was ground contact treated maybe better..

All told I had about $500 in it including running a new circuit and adding the fan and lights.

So, I'm trying to figure out if a 15 gauge metal fence post from Home Depot would be adequate?

I would recommend not attaching it to your fascia and I also recommend using metal/steel posts as well.

Why not a 12' 4x4 and bury 2 feet of it? That'll be solid. Then you can screw in some eye bolts and attach the shade to them. Be sure that you have a way to adjust the tension on the shade because it will get loose & tight depending on the temperature.

Also. You don't have to add water to your concrete. Just pour it in and shape the top so water doesn't sit against the post. In a day or two enough groundwater is absorbed to set the concrete.


Sorry, but this is just wrong. I can understand mixing in the hole as a compromise, but expecting to get a monolithic block from leeching ground water is wishful.

We did one a few years ago at work. Don't remember all of the details but you need to design the footing for just uplift. I would use at least 25-30 psf up and neglect the dead load completely. Take your tributary area, multiply it by the area pressure (25-30 psf) and make sure you've got enough concrete to resist that force. FYI, concrete weighs about 145 pounds per cubic foot.

This is good advice. First, fascia is not a structural member. Second, you're just providing an avenue for water to get into the fascia and start the rot.

Agreed. You want an even mix poured in otherwise you could end up with an outer shell of set concrete filled with unset mix. The concrete needs to set and cure evenly.

Dallas area, so no hurricanes, but yeah, I know I'll have to take it down from time to time.

Wind will rip that 1x fascia rite off

thats why you should go in and fab some mounts to the frame and have a bolt coming out of the fascia.
