Hi- I've got a 40 year old beach cottage with the original A-frame tin roof. It is not vented; has no ridge vent nor soffit vents. May have some insulation but is definately not R30 as heat does build up inside house. Only plus is that it doesn't leak. Other than tearing off entire roof off and starting over have any suggestions? Would building another metal roof several inches above this one be the answer? and, would having the space between old roof and new roof vented handle all moisture problems? Pleae advise. Tinman

You may want to investigate a product called RoofHugger. In any event, if, structurally, you can build up an air chamber and then vent it and roof over that, that would be a fine way to go for heat and moisture control. Todd Miller

Todd - Tks for info. Looks like it will do the trick. Only question still is do I have to also cut vents into existing roof to get any potential moisture released into new cavity or does just venting space between old roof and new roof do the trick. Tinman

There would be nothing rong with puting in some vent holes. My general feeling is that they will not be necessary but there would bo no harm in it either. Todd Miller
