Roof sheets for summer house

[david lawrence]

Hi 

am building an outdoor kitchen / summerhouse ( although it will be used in winter as well )

will be heated with a wood burner 

Want to avoid condensation from metal roof sheets

What’s best and economical ?

plain sheets then insulate

anticondensation sheets then insulate 

double skin sheets with insulation sandwich 

I have seen old box profile on a shed with a thin layer of foam on inside but can’t find it on line is this no longer available ?

any tips

thanks

David

Simple and cheap solution,  cover roof area with a tyvek type membrane, to drain away condensation to outside wall area,  battens on top then a standard uninsulated galvanised or coated corrugated top layer to weatherproof. Works great in my workshop with no dripping.

Don't tighten membrane too much, to allow a natural valley to form, carries water away from woodwork and speedily away.
