We had a new shed 3 months ago and we’ve noticed the roof is bowing on the inside. no sign of damp, no issues on the roof and guttering alongside is clear. where do I go from here? Do I need to support it more? Cheers
Looks like its too big of a span for those timbers and they are too far apart. Who did you buy it off, I'd be going back to them.
Just remember it's a shed. It's not a proper building that follows a code it's built down to a price.
