Attach awning to brick facade

[MarcusW1]

Hello everyone!

I recently purchased an awning that, after discussing with friends, I've become uncertain about whether it can actually be mounted properly on a brick facade without risking it coming loose or dislodging bricks.

The roof is of the following type with 4 attachment points.

The challenge seems to be attaching the roof to something other than just bricks.
One idea is to place it a bit lower than recommended to try to hit the lintel above the front door with the lower screw holes.

Does anyone have experience or thoughts on this? Even the supplier didn't want/couldn't provide an answer on this, probably to avoid taking "responsibility".

You should not hang that roof on a brick facade.
You must have posts at the outermost edge.

That roof should not be hung on a brick facade. You need posts at the outer edge.

I don't understand why there must be posts at the outer edge?

Checked the plugs for bricks and if you have hollow bricks, I think the roof is definitely too heavy to only be attached to the facade. If you have solid bricks, then maybe it depends on the dimension of the roof you bought. But even there, it's still borderline.

What does it look like behind the bricks? Is there an air gap, or are there fastening elements behind that you could use a longer through bolt to?

Many years ago, I attached a similar canopy to my house with a brick facade, but then I used screws that were so long that they went all the way into the wooden facade behind. The holes in the brick were slightly larger than the screws so they went through the brick freely. Worked excellently.

I don't understand why it has to be poles at the far end?

Having poles means there is no bending force. Then it's just weight downwards, not outwards.

If there are posts, there will be no bending moment. It will only be weight downwards, not outwards.

Yes, absolutely, I agree, studied engineering and took strength courses. But have you even checked the OP’s link? Posts don't work with that roof without further modification. Moreover, you wrote that there must be posts, which is hardly a must in all situations.

there you will find answers on what they calculate with for fastening

I think I can reach the wooden beam above the door frame if I use really long screws in the lower mounts.

Yes, I'm definitely aware of that, studied to become an engineer and have read structure. But have you even looked at the TS link? Posts don't work with that roof without further modification. Moreover, you wrote that it must be posts, which is hardly a must in all situations.

We always called högskoleingenjörer high-waisted or technicians during our study time .
When balancing against posts, you don't get any bending effect. Just downward pressure.
Attaching with bending effect in facing bricks is something you can deal with at the high-waisterian (light engineering education).

That roof should not be hung on a brick façade.
You need to have posts on the outer edge.

But if you look at the model, it's a roof meant to hang on two brackets on the façade.
If you use posts, it's a completely different construction/model of roof.

Then maybe this model of roof doesn’t work on a brick façade, I don't know.
But I would think that as long as the brackets are sufficiently high and you find the framework behind the façade and can screw into it, so it’s not just hanging on the brick, it should probably work.
