Hi all, oh dear just had my wife on the phone as she went to work a night shift, she told me she had water drip onto her head from the roof, pop top I guess, yesterday we heard a noise that sounded similar to water, but also sounded like something rubbing together, anyways there was a tiny amount of droplets on the canvas inside when I got the roof up, and a tiny tiny damp bit at the base of the canvas as I ran my hand along the side of it, inside....any ideas guys or gals what this could be and where shall I start looking for issues?
