okpermanent Posted October 26, 2023 Report Share Posted October 26, 2023 Hello all. In installed a metal roof about four months ago over an existing shingled roof with fir straps 24" on center. On two occasions now the roof has leaked. The first time was when we got our first dusting of snow last month. Today was the second time. It's been below freezing for the last week or so and today it's around 40. The room where it leaks has a cathedral ceiling with 2 x 8 rafters so there is 7" max for insulation. I am thinking the heat loss is escaping and hitting the back of the freezing metal creating a lot of frost and when it warms above freezing like today it drips creating a leak in the house. Do you agree or am I missing something? The first leak was on one side of the room. Today it is two spots on the other side of the room opposite side of roof. There are no pipes or anything protruding through the roof in this room. roof replacement springfield va Quote Link to comment Share on other sites More sharing options...
Eric - TIA Posted October 30, 2023 Report Share Posted October 30, 2023 Wish I could help, but I do not have any experience with metal roofs. However, I do want one. Quote Link to comment Share on other sites More sharing options...
Altan Posted November 4, 2023 Report Share Posted November 4, 2023 I would not go for metal roof in cold and damp climate, condensation might be an issue. I have seen some photos of under roof heating system, that might be a help to dry out the condensation. It might sound a bit crazy but I would cut the felt into roof tile shape and melt it on the roof (concrete or plywood). Quote Link to comment Share on other sites More sharing options...
