Finding a leak in a flat roof can be considerably more challenging than locating one on a slope. For one thing, sloped roof leaks tend to appear at or below the leak point, whereas a flat roof leak can spread out and seep through at a considerable distance from the actual leak point.
One of the best times to search for a leak in a flat roof is after the roof dries out.
You can then easily spot locations where standing water pooled on your rooftop by looking for the concentric rings left as the water evaporates. Search for small holes or cracks in your roof in these areas.
Pay particular attention to flashing and seals around vents and other protuberances that penetrate the roof. These are common locations for leaks. Don’t limit yourself to penetrations that occur near standing water areas; a leak elsewhere can also let in water that may not show up for hours, days, or even weeks.
It’s also a good idea to examine the perimeter of the roof, since seals or flashing in these areas can have leaks as well, and the water may travel beneath the surface for some distance before appearing inside.
Finally, inspect covers for vents and exhausts to ensure that they are all firmly in place. It’s possible for a loose cover to allow water in that may penetrate a seam in the duct or pipe.
