What to treat mouldy shed roof with?

aliasojo

I've just dismantled a shed in order to resite it. During this, I've found out that an area of roof (corner edge) has been affected by damp and the chipboard stuff it's made from has swollen and is a little mouldy.

What can I treat this with in order to stop it getting any worse? I'm buying new felt for it but I don't really want to be spending money on replacing the roof as the shed has only got to last another 6-12 months before it goes anyway.

dont bother then. it should last another 12 months.
you cannot teally treat mdf/chipboard anyways once its wet.

ps
a new sheet of OSB is very cheap. 10/15 quid.

That was pretty much the fate of our old shed though it was a timber roof rather than OSB/chipboard. We cut out the worst rotten timber, patched it up with whatever timber was around at the time and bought some cheapy felt from wickes and refelted. It didn't stop the rot continuing but we got a few more years life out of it before it's demolition. When attaching the felt or battens around the edge you can't nail into soggy rotten timber. I'd cut back the bad part of roof with jigsaw get a small piece of new suitable board to fit and fix to the old with battens on the underside then felt over.

...then save up for a nice new shed...like mine! . TBH the cost of the shed is only the tip of the iceberg - the base, shelves, workbench, electrics etc all add up and the cost seems to be snowballing!

If it's only to last 6-12 months, dont even bother with the felt.
