I am trying to use pbr textures with node wrangler but i am getting weird results and ugly effects, even with all maps, it looks like as if the maps are not set in the right direction. I dont have GPU, maybe thats why this looks so ugly? i use intel HD graphics 1400. i was even trying to model the roofing by hand but this would take very long time and i think its not worth.

Currently, your material only has "fake" bumping. To have actual "real" 3D bumps, follow these steps:

In your material, add a Displacement node right before the Displacement input socket of the Material Output node:

Then, be sure that your Render Engine is set to Cycles and enable the Experimental Feature Set:

Then select your roof object, and add a Subdivision Surface Modifier to it, set it to Simple, and check Adaptive Subdivision:

enter image description here

And finally, go into your Material Properties and under Settings > Surface set the Displacement mode to Displacement and Bump:

enter image description here

This should give you accurate 3D bumping based on your image texture.

Also just as an advice, it's always beneficial to use the latest stable version of Blender: https://www.blender.org/download/
