Not Horizontal ?

Or just an optical illusion ?
The foreground roof tiles were painted in white years ago.
Canon T6, 50 mm (the rest is in the EXIF).

That little bit of vertical building edge suggests that it could be rotated a degree or two clockwise.

Slight tilt to the left.

I put a plastic ruler on it, the two vertical walls seem vertical OK with a Straight Edge. Not only do the angled roof lines and curved hills and trees make it confusing, so does the lighting; bright and barker areas on walls. But with a tool the walls seem vertical to me.

I enlarged and slid the vertical wall corners to the right edge of the screen.
If it feels more than about 5 degrees, it's an optical illusion.

Based on the lack of all the facts, the camera may have been on a tripod and the camera leveled according to a bubble level. However, to my eye, and judging by the alignment of the lower edge of the tiles, I'd have to say the photo is not horizontally level. Just my $0.02 of opinion.

Like I said, less than 5 degrees? The optical illusion is greater that the tilt.

When I want to check whether a photo is level or horizontal I open the photo in PSE and draw a line with the brush tool along the horizon or a vertical object and adjust accordingly. When corrected it I remove the line.
It is off a little

To all:
Thanks for watching and I do value your input.
The camera was in my hands, no tripod. It is amazing
how so little deviation can be noticed. And, BTW, how
to correct it with a not so precise optical mouse ?
But... I have always said to my wife that the addition
done to my neighbor's house was not precisely
vertical.

The degree rotation in my editor may not be precise enough, only being able to do a degree or two over or under, so I just select the best look. Granted, in this case the deviation is probably "enhanced" by the roof angles. Sometimes water shore lines that are angled also yield the same impression of the image not being level.

I will try to do it on DPP4, for the while. I have others, but still learning.

Make the vertical line on the building vertical.
I will try.

OK guys, I can get all fussy and check using Ps CS6 too. But it really is not obvious it is not level via the building by just looking. I'm usually one of the first to spot an off horizons. I decided to look at the vertical wall closer to the center of the image. Where there should be less distortion by the lens. There I found the wall to be off vertical by 1.5 degrees. See detail below.
