Roof sheets profiles not aligning
I recently had some new polycarbonate roof sheets installed. I was told by the roofer our roof was greca profile, so of course he used that profile for the new sections. The problem is the profiles don’t match. Photos here:
To compare the 2 , I measured between the screws that are placed every 2nd rib. If I measure between the screws on the new section, I get 145mm, but the space between the screws in the old section is around 175-180mm.
Any ideas as to what’s going on?
