Attaching an entrance roof to Mexican brick

[delux]

We have a porch roof that I was thinking of installing by the front door. Metal frame with roof sheeting.
The house has a façade of mexitegel. Is it possible to attach the roof directly to the brick using these https://www.byggmax.se/spik-och-skruv/plugg-och-expander/fasadplugg-10x135mm-1st-p24114 or should I try to get the screw to attach to the frame inside the mexitegel? Suitable screw for this?
I don't have the exact weight of the roof, but I guess it weighs about 25 kg.

I would try to attach it to the frame inside so that it can withstand any snow that may settle on the roof. Do you know what it looks like inside the tiles?
