Is the Roof to Blame for a Ceiling Leak?

ceiling leakA ceiling leak shouldn’t be confused for a roofing leak. Just because water is emanating from the ceiling does not mean that the roof is the problem. The drip point isn’t always the source of the leak. Water follows the easiest path until it reaches an obstruction or the lowest point. We’ll consider possible sources of a ceiling leak if not from the roof.

Sources of a Ceiling Leak


Clogged drain pipes can cause leaks. If the water appears fresh, then bad piping is likely the culprit. If the water looks dirty, then it’s more likely a residential roof leak.


HVAC systems are often installed on the roof in commercial facilities. AC condensation from a faulty unit can cause water to overflow. When this happens, the water enters the ducts, leading to drips from the ceiling.

Walls, Doors, and Windows

After a heavy rain spell, water can make its way through openings in doors, windows, or cracked walls and eventually travel to the ceiling.


Clogged gutters can become overburdened with water runoff. The water buildup can lead to drips in the home interior. Our additional services include gutter inspections and maintenance.

What About the Roof?

Of course, the leak can very well be coming from the roof. If so, the most likely cause is an opening in an area that protrudes through the roof. This includes flashing around the chimney, attic dormer vents, and plumbing vents. An inspector can repair these areas using roof cement or tar. Wind-lifted shingles are another potential point of water entry.
