Metal Garage Roof Condensation

Jetfire

In my single breeze block garage, we installed a metal roof as the old one was fucked. (Apparently, previous owners set off a firework inside it and it smashed the roof to bits and did a bodge repair..) So now its winter, have a very wet condensation covered metal roof. its a slanted roof from bout 8.5 foot to about 7 foot and Ive not seen it wet from leaks when it has rained in the summer so I guess its warm/cold air. There are two fixed windows in the garage so Ive taken one out now to give a bit of an airing. 

Anyone had any experience in fixing this? The spray foam insultation seems to be the best way to do it.

This is something I need to look into also, I replaced the knackered old concrete panels with steel profile panels on my double garage, I ran out of money to insulate it & the condensation is bad in Winter especially when it freezes then thaws out, I've had to take my power tools indoors.

Rising damp needs to be considered too. Is the garage connected to your house?  Is there heating in the garage?

Ventilation and insulation of choice.....

Very tricky to deal with.....I guess the walls are single skin brick also, and solid floor ?

 You would need to make some effort towards insulating the whole thing to have any real impact.

Low level heat and a fan will also help.

So this the garage. Its single brick with the metal roof as shown. There is single glazed windows but they dont open so i took one out (frame needs replacing anyway) to hell air it out. 

The interesting part is there is a pit which has been filled in with loose gravel/dust/soil. But that will be something to think about later..
