seasonal cottage heat

WinterH,
A simple way to combine a roof replacement with insulation is to use overlap metal roofing and 1.5 inch foam. Install 2x4s laid flat and 2' apart as your roof purlins and then drop 1.5" sheets of foam between the purlins. If your rafters are already fairly strong you might even be able to place the purlins 4' apart, still have a solid roof, and save some on the high cost of lumber. Best part is that even if you don't have a lot of mechanical skills you can probably undertake this relatively simple project. An inch and a half of foam, especially if it is reflective faced, lining your roof will make a huge difference both summer and winter ...and might this qualify for a energy improvement tax credit? I don't know but it is certainly worth asking
