I get the feeling that the roof is newer than the wacky run. I may have been straighter before the roofers pulled it to one side for thier work, and never put it back. The other stuff on the roof being a bit more rigid, they just lifted up, splid new roofing under, and put it back down. The very slinky PVC they just dragged around, after all, whats it gonna do? Leak?
I will eventualy fail, that guys just hoping its after he retires.
