8 Reasons Why Your Roof Is Leaking

Oftentimes when a homeowner thinks of a leaking roof, they think of missing or broken shingles. But there are more to roofs than just their shingles, roofs contain multiple pieces within them where something can cause a leak. Leaks can do more damage to your home than you could imagine when left unrepaired, so spotting leaks and getting them fixed is important.

Once you know all the places to look for potential leaks, it will be easier to identify leaks quicker and be able to resolve the issue and protect your home. Here are 8 reasons why your roof is leaking.

1. Cracked Flashings

Flashings are made of metal and their job is to help redirect water away from the joints in the roof to help avoid leaks. While this material is very durable, it can slip out of place, or the caulking may dry and crack over time. Ultimately water doesn’t care how small the crack is, it will find its way inside.

Finding the source of a leak isn’t always an easy task. When it comes to if the flashing is cracked, the signs are water pooling in your bathroom vent, chimney, or similar places a flashing is utilized.

2. Broken Shingles

A broken shingle is not always easy to spot as it will depend on the slope of your roof to how visible they are. But if you have a leak, looking to see if you have a broken shingle is a good starting point.

On most roofs, a broken shingle will look like a dark spot on your roof where the underlying material is exposed. Shingled roofs are built with overlapping shingles, so the shingle may not cause trouble at first but will eventually cause a lot of issues. Call LOA Construction for a roof repair for any broken shingles you may have.

3. Improperly Sealed Valleys

Most homes have peaks and valleys, and the valleys can take a beating due to the fact that they are the low point of the roof. All of the water runs down the slope of the peak and through the valleys. As this is known, they need a special barrier in the form of a valley flashing. If it’s not properly sealed it could crack, meaning a leaking roof.

4. Cracked Vent Booting

Those pipes that protrude from your roof act as vents to allow any air moisture to leave your home. These pipes have a tight rubber ring around them called a boot as well as a flashing at the base to prevent leaks. This boot ring can wear over time and crack causing a leaking roof.

5. Skylight Leaks

Skylights are great for aesthetic appeal as well as allowing extra sunlight to shine into your home. However, whether your skylight has been sized wrong, not sealed correctly, or simply been damaged with time, it can cause them to leak. This could be a leak in the skylight itself or the flashing around it.

6. Clogged Gutters

Clogged gutters can prevent water from properly running off your roof. If not properly taken care of, the gutters may also become heavily disconnected from the house. Then water runs off the roof, but in non-ideal places which could cause basement or foundation leaking. The lifespan of vinyl siding or other household materials may be diminished by runoff.

7. Cracked Chimney

Most chimneys are made of bricks, and the bricks are sealed together with mortar. The mortar is a highly durable paste, but over time weather or foundation, issues can cause the mortar to separate and crack. When this happens, the mortar needs to be replaced to stop the leaking roof.

8. Moisture in The Attic

If you notice a musty smell from the attic and the ceiling, it may or may not show new signs of a leak. Instead of a leak, it may just be that moisture has become trapped in your attic and showing similar signs of a leak. When the temperature increases and the inside is cooler than outside, this water will condense. This water may be enough to cause a drip into your living space or it may cause mold and mildew.

If your vents have become blocked then it may be preventing moisture from leaving your home. Ensure that these vents are clear from being blocked, this should resolve moisture retention. If mold and mildew are severe, those may need separate treatment.
