I have been doing research on what type of roof I want to install on my home. I have a covered deck with a metal roof and was going to re-roof the whole house with 5 rib metal panels just like the deck. Well the deck has issues already with condensation, expansion contraction noise, and now leaks around the screws after 2 years. I've been reading the metal roofing.com board and it seems that everyone has problems with everything about the installation. I've spoken with the metal roofing manufacturers and none seem consistent or even seem to care about installation. I do like the look and don't question the durability of the panels, I'm just thinking that maybe metal is best for barns and sheds.
