The workshop roof has collapsed in the recent high winds. I'm wondering what my options are to replace it.
It's 20-something feet square, breezeblock construction with big windows down one side and a big door. The old roof was cheap clear PVC corrugations at a very shallow (but not flat) pitch. Having far too much transparent surface and no insulation whatsoever, the place was boiling in the summer (45=B0C once !) and freezing in the winter, with terrible condensation problems dripping from the roof.
The PVC is of uncertain age but it's clearly now brittle and one sheet has failed completely. The only option is total replacement, probably with some haggling with the landlord for them to stump up some money for decent materials and I'll do the work. The timber underneath isn't generous and needs some patching, but it's no big deal.
What to replace it with though? I'm thinking of double wall polycarb, maybe in bronze to keep the summer sun down. I wonder if I could go completely opaque though. I don't need the sunlight _that_ much and any winter warmth is a bonus.
Any advice?
