I have a timber fram with a stress skin roof.(4/12 pitch) The current shingling was applied directly to the panels, over tar paper. I have seen on newer construction, that the roof is often re-sheathed over sleepers, to allow for an air channel under the sheathing. Is there a real advantage to doing this? I need to re-roof this spring. If it was your place, what would you do?
Thanks

If I were in your place (which I expect to be in a couple of years- see my post "Timber frame addition") I would put on a metal roof. With the high R-value of a stress skin panel you do not need sleepers. You did not mention the climate in you area. The space provided by sleepers would allow for circulation keeping a roof cold in the winter and preventing snow from melting and creating ice dams etc. Your panels should not be allowing heat to escape and melt rooftop snow, however if you have had problems with your shingled roof I always recommend ice/water shield for valleys and bottom edges (at the very least). I have seen ice/water shield put onthe entire roof in Colorado snow country. Good luck, JP
