Discovering the source of a leak in a flat roof is usually easier than finding one on a sloped roof or a shingled roof. That said, roof leaks of any kind can be more complicated than they initially seem – especially if you’re an amateur trying to DIY roof repairs.
There are many reasons for this, starting with the fact that the spot where you initially notice water entering your interior rooms might not be where the leak itself is, since water that penetrates the membrane of your roof can travel across the shelter until it reaches a seam in the sheathing/roof deck, skylight or electrical, HVAC or plumbing penetration and then manages to drip or seep through to the inside.
