I'm in the UK.
My garage has a corrugated metal roof with no insulation. In the winter, when it rains the underside of the roof drips. Not massively, but just enough to be annoying.
The roof appears to be in good condition and not old, so suspect this is condensation. Although I can't rule out a small leak.
As I do not have strong DIY skills I have been looking for a solution which is within my means. I have settled on staple-gunning sheets of aluminium bubble insulation membrane into the beams, spanning the distance between two beams, as close as possible to the underside of the roof.
- Is this a reasonable solution or will it cause more problems?
- I'm concerned that covering the whole roof tightly will trap damp above the bubble-wrap, causing mould on the beams.
Or if I leave gaps for air to circulate above the insulation then that defeats the point.
