Okay, I have some free time to refresh my tileable textures creation skills. I have started with more complex texture, but Photoshop crashed on me before I have saved my work.

Then I decided to choose less complex metal texture from CG Textures free collection: http://cgtextures.com

Here is preview of final texture rendered with use of displacement:

CrazyBump was used to create Displacement and Specular maps.

You can download final Bronze Copper Metal texture here: http://retrostylegames.com/temp/blog/seamless-bronze-copper-01/seamless-bronze-copper-metal-roof.rar

It’s 1400×1400 resolution .TGA files.
Diffuse, Displacement and Specular maps are included.
