My friend bought a cheap shed off t'internet a couple of years ago. Given the appalling weather of 2012, followed by the lousy wet spells we've had ever since, the shed hasn't stood up to things very well.
It's crammed with "stuff" (not rubbish: kit and materials for which there's no room in her garage) and the stuff is all mildewed, along with some of the timbers of the shed itself. The roof has been permanently damp (or even dripping wet) *inside* for almost a year now: it's almost as though the roofing felt supplied is porous!
I've now built a second, industrial quality, roof on top of the original, the weather (and space available) not at present being conducive to emptying the shed and removing the old roof.
I'd like to ventilate the shed to assist in getting rid of damp which builds up. I was thinking of making a few 1" holes in the apex of each end of the shed, and making a few more near the bottom of the walls, allowing a steady flow of air at all times.
Any comments, or suggestions of a better way to ventilate it, please?
Cheers John
