Interference Fringes?

This shot of some industrial buildings was captured using my E-M1 Mk1 and ED 150-300 lens at 140mm FL.

The buildings are covered in corrugated sheeting. They are about 2,200 metres from the camera.

On the grey building, these green and magenta bars appear.

In other images at a slightly longer FL, the blue coloured sheeting also has green stripes.

What causes these stripes? I take them to be interference fringes.

Would a camera with an AA filter avoid this proble?

I would appreciate any comments.
