How a Leak in Your Roof Comes About

Moisture in the ceiling or on the walls usually indicates a leak in your roof. When moisture has appeared, the leak might have already affected the interior of your roofing system and insulation. If the visible moisture has been there for a while, you might have to deal with water damage on top of roof repairs.

Water can enter because of missing or severely damaged shingles, flashing, ridge cap, or any other part of your roof that is not in good condition. In a slanted roof, it will penetrate into the sheathing and rafters, trickling along the inner surface of your roof. Once it reaches your insulation, the water will accumulate and possibly create mold and compromise the structural integrity of your roof.

This will all be hard to detect for an ordinary homeowner because the slope of the roof makes the actual leak location hard to find. If you check your attic, what you immediately see might only be the apparent leak location, since the actual leak might be coming from a higher part of your roof.


Determining the cause of the leak is the key to effective repair. This way, you can prevent wasting time and money on working on your roof and then finding out later on that you still have not addressed what causes the water accumulation in your home.
