the plan?

Got the east edge piece of roofing up this morning....now comes the tricky part.  Seems the engineers who designed this building have not thought through all the details.  Just about figured out how to meld two different profiles of roofing - the trick is that the two different materials don't line up with their peaks and valleys.  The corrugated metal is a pure sign wave and the polycarbonate is a modified sign wave with a different frequency.  Who'd a thought the greenhouse design would be kinda like my electrical systems?  Hmmmmm...  48.74,25,0,C
