Condensation Problem with Vinyl Roof Cover

[wheesht]

Dear Jafo

Thanks for your speedy reply.

That's good to know about the air/energy barrier. It will be great to get rid of the condensation

we have a 5' diameter hole in the middle of the roof with a roof cap with clear vinyl panels as skylight windows. We have the cap propped open a few inches 24/7 on both sides since discovering the condensation to attempt to allow air to flow - I think that has been helping it.

I've also fitted a 4" extractor fan above the cooker today which will hopefully help too.

It's a good idea to fire up the burner and get the roof cap off - it's hardly on all summer but I don't really think to get it off in the winter - it's held down with tyres at the moment since there were supposed to be gale force winds last night.

I plan to change to reflective insulation , sounds like a good solution - it's far cheaper than changing the vinyl to canvas too.

Many thanks again...hope you get some rain this season at least!
