Hi All,
For the second time this year (last time was in January during the last really cold spell) I've had melted snow dripping on the inside of a bedroom window.
The house is an old detached edwardian property with pitched clay
tiles over a boarded roof.
The pitch of the roof decreases above the soffit at the boundary of the outside wall and I've recently noticed icicles on the outside wall where the soffit meets the wall.
After the last winter I had all the tiles replaced on this side of the house as the original ones were getting on for 100 years old and beginning to fail.
During this recent cold snap exactly the same problem has occoured.
The only change we've made to the property in recent years is that we've converted an old box/tank room on the 2nd floor to a heated study, so although this area is insulated there is considerably more heat in this space.
My best guess is that ice is forming at the point in the roof where the pitch changes and the additional heat at the top of the roof is causing snow to melt and reinforce this dam.
I guess that the best fix would be to lift the new tiles in the spring and install a waterproof membrane between the boards and the tiles or is there something I'm missing here?
All advice would be appreciated
Steve
