So I recently purchased a 90 yr old bungalow-ish house. I was looking outside and discovered underneath the white vinyl siding it looks like all the original cedar shakes are there. I would love to pull off the siding but I'm worried that the shakes will all be in terrible shape and I'll need to replace them. That's something that just isn't in the budget. However why on earth would they have left the original siding? Insulation? Laziness?
