We currently have a small problem with our carport roof. It is dripping from the ceiling.
It is exactly at the lowest point of the roof. In the photo, at the corner of the house behind the wooden posts, is the downpipe. I fear that two weeks ago, when I was removing weeds from the roof, I damaged the membrane. Probably the water now runs from this damage under the membrane to the lowest point and penetrates there through the sheathing. Since it takes some time after a heavy shower for the dripping to start, I fear that the damage is not exactly at the downpipe. I am concerned that the moisture under the membrane, which likely dries poorly, will cause damage over time.
My question: Are there any clever ideas on how I can find the damage? The carport roof is greened, so it would be relatively laborious to check the entire area.
I had thought that when it is dry again, I could selectively pour a large amount of water onto different corners of the roof and see when it starts dripping again.
