SATTV:We have a 1966 decromastic roof tile and I know it is nearing the end of its life and one of my questions was going to be about replacing the roof but he beat me to it.
Ugh, yeah, if you've got Decromastic the first thing I'd do before putting up solar is get it replaced. As with Insulfluf, if you Google it almost all the hits you'll get are for companies offering to get rid of it for you.
I do like the idea that the Americans and Canadians do by putting up ply, I like the idea of a solid barrier, makes working on the roof more secure.
That's one thing I've never understood, why do we not put OSB or ply under the roof here? You've got nothing but some flappy building paper under there, no extra barrier or structural component.
