I imported a file into blender, but it seems the texture is a little bit weird. the grey object should be a bitumen roof. the side looks good, the top and the bottom are just weird. Even though the wrapping mode is "repeat", the top and bottom seem to have the wrapping mode "Clamp", at least that's what it looks like
Does anyone have an idea how to fix it? or more - what is the problem? are the uv coordinates wrong?
Here is the building I am working on:
and here is the texture I added to the roof:
