I recently had the shed roof replaced with felt but it has started leaking.
Not sure whether it needs another layer of felt or whether the felt has not been laid properly?

The shed area is around 30 square metres and the roof consists of new hardwood ply which has been felted, but the ply is now getting wet in several places indicating that the water is coming through the felt.

I have left my email & phone number on here so that you can also contact me directly.
