6 Common Causes of Roof Leaks

Knowing the common causes of roof leaks is important when it comes to home and roof maintenance. Over time, certain fixtures must be repaired or replaced. The roof is no exception. It is one of the most important features of a home because it protects what’s inside and its structural integrity. Every homeowner should know the different causes of how a roof can leak, prevention, and who to call to fix it.

Pay Attention to Common Causes of Roof Leaks 

The following issues may be present even before the roof starts to leak. Save time and money by addressing them immediately.

1. Cracked Flashing

Underneath the roof shingles and on the joints of a roof are thin pieces of metal, called flashing. Its purpose is to create a barrier to keep water out. It’s usually found around the vents and chimney. Flashing cracks when the sealant used to keep it together begins to corrode. It also can suffer damage from strong winds and rain.

If the flashing is cracked or broken, water can seep through and cause a leaky roof. It is recommended to routinely check the flashing around your chimney and vents to ensure that cracks aren’t letting in moisture.

2. Broken Shingles

Sometimes heavy storms can cause roof damage. If you find shingles on your lawn, you may have others that are loose or broken. If any shingles are missing, the exterior layer of a roof becomes exposed to moisture.

If this is the case, it’s best to have a roofing professional come out and thoroughly inspect your roof. They can replace any missing or damaged shingles to prevent your roof from leaking.

3. Ice Dam Buildup

Winter months bring cold temperatures, snow, and ice. When the temperatures remain below freezing, the melting snow that is caused by the heat from the attic will run towards the roof’s edge and eventually refreeze. Ice then builds up on the edge of the roof forming an ice dam. Your roof can get damaged by the weight of both the ice and water.

Homeowners who live in colder climates should have the proper tools to remove snow from their roofs. A roof rake can help with removing snow from the roof’s edge.

4. Skylights Not Installed Properly

Water leaking near skylights is caused by improper installation or decayed insulation along the edges of the skylight. Clear off any debris from the skylight and check for cracks. You’ll need to have the windows repaired and properly sealed to prevent further moisture from seeping into your home.

5. Clogged Gutters

Leaves, sticks, and other debris are constantly getting stuck in gutters. Gutters are responsible for directing water away from the roof. If water is not flowing out of your downspouts during a rainstorm, then your gutters are clogged. This will cause the rainwater to pool gather in an area on the roof, eventually resulting in leaks.

Regularly clean your gutters during rainy seasons. There are many gutter accessories on the market to prevent blockage from debris. You may want to invest in gutter leaf guards. They come in two styles: screens or surface tension.

Gutter screens are a mesh barrier that is placed over the top of the gutters. The holes block any solid debris while still allowing water to run through them.

The surface tension model fits over the gutters. They leave a small slit between the leaf guard and the gutter. The rounded rim curves back toward the house, so when it rains, the water goes through the slit and collects into the gutter. Any large or heavy debris rolls over the edge.

6. Condensation in the Attic

Condensation comes from moisture in the air. It is formed when warm, moist air touches a surface that is colder than the dew point of the warm air. Condensation is a sign of inadequate insulation or ventilation. The attic will have moisture if the warm air is not allowed to escape.

A leak may be coming from your attic if there are signs of mold growth or mildew. Always treat the mold first.  Then take control of ventilating it and remove the humidity in your home. Soffit vents should be clear of any obstruction to allow the flow of cool air from the outside into the attic space.  This will keep the attic free of moisture build-up.
