Causes of Roof Leaks

Broken Shingles

After a storm with high winds, heavy rains, or hail storms it is easy to spot remnants or whole shingles scattered across your yard. But you can also tell you have broken shingles by spotting different colored patches on your roof itself.

Clogged Gutters

Cleaning your gutters, a once a year to do list item that you will regret putting off. If there is a lack of water draining from a downspout during a rainstorm and you can spot leaves sticking out, it is about that time. Gutters are essential to helping water travel away from the roof’s surface and if a blockage is formed, the water will stop and pool in an area on your roof. This gives the water an opportunity to seep through any cracks that they have been present.

Flashing is Cracked

Flashing are metal sheets that are under shingles and on joints of a roof to create a water resistant barrier. These can either be concealed or exposed. If they are concealed, It will appear as a rubberized coating overtop and if exposed, it will look like long runs of sheet metal. Where the damage happens, is when roofers use tar to seal the flashing together and it corrodes over time. This will cause a large crack in your flashing which allows water to enter your home. Have your flashing routinely checked around the chimney and vents.

Vent Booting Is Damaged

Used to release moisture from inside your home, roof vents are the small pipes that stick out from the top of your roof. Because they release moisture, they can leak and create dark spots in their damaged areas. In order to prevent leaks, a rubber boot is placed around the base of the pipe where it peeks out of the roof. Roof vents are sealed by placing flashing around the opening as well, but over time this flashing can break or decay.

Ice Dam Buildup

A ridge of ice that forms at the edge of a roof is called an ice dam. These are formed when the temperature from the attic causes snow to melt. The water then runs between the roof’s surfaces and will refreeze when it hits the roofs exterior edge. When these form, it can preventing melting snow or water from draining off your roof. The sheer combined weight of ice, snow, and water can cause severe damage if it is not properly drained.

Valleys Aren’t Sealed

When two roof slopes meet, it creates a valley. Because water follows along vallet lines, they are particularly vulnerable to damages and leaks. If these valleys are no properly sealed, rainwater can run under the seals and damage the interior of the roof structure. Damages can occur if the seals were not done properly the first time, they were stepped on, or they have eroded over time due to heavy weather conditions.

Attic Condensation

The attic acts as “barrier” between outdoor and indoor temperatures. Due to this clash, condensation can form and moisture will soon follow. If you are smelling a strong, musty odor coming from your attic, it may be a sign that water has gotten inside and it has created mold or mildew.


Leaks caused by skylights or other ceiling fixtures are very easy to spot. If you are finding that are consistently seeing water on your floor beneath a skylight, you have the culprit. If the wet spots are near the top of the skylight it may be due to another issue. But often times, these leaks could be due to improper measuring and fitting during installation, a flashing issue, or insulation that has decayed over time along the edges.

Chimney Crack

On the top of a chimney you will find a mud cap or a mortared area. It is essentially a mixture of sand, water, and cement. It can easily erode in harsh weather conditions. Holes in the mortared joint, located where the chimney connects to the roof, or wear and tear along the mud cap, can cause leakages. You should also keep an eye on loose shingles or cracked flashing around the area.
