i am renovating a very traditional colonial built in 1930. the current siding -- which i like very much -- is a (unique) very thick cedar shingle (1" at the butt), with "11 inches to the weather." according to the homeowner, the siding was painted around 4 years ago, but it is already exhibiting signficant peeling. my contractor and a painter that i talked to thinks that the peeling is likely due to moisture that is going in the back of the shingle. thus, priming and repainting is not a long-term solution. so... any other ideas for what to do? scrap the current siding and replace? replace with what? hardie? thanks
