Signs and Common Causes of Leaking Roof

A leaking roof is a major roofing problem that should never be ignored as it can significantly impact the roof’s integrity. No one wants to see water leaking through their roof. But, even with a regular roof inspection in San Antonio and maintenance, harsh weather can take a toll on the roof, causing leakages.

However, if you educate yourself about the common causes of leaking roofs, you can make informed decisions and, more importantly, be prepared and prevent further damage to your roofing San Antonio system and house.

Signs of a Leaking Roof

While water leaking from the ceiling is one of the common signs, below are other less obvious signs that indicate a leaking roof.

Stained Walls and Ceilings

A water stain will look like a large puddle on the ceiling, ringed with brown color. However, some stains are difficult to notice if they occur in the corners. Even small stains indicate a much larger leak.

Unpleasant Smell

If you smell something unusual in your house that lasts for more than a few days, you’ll have to look for signs of roof damage. When a roof is leaking, you might notice a musty smell when you turn on the HVAC system.

Spots on the Exterior Wall

Take a look under your roofline outdoors. If you see water spots, you may have a problem where the walls meet the roof.

Common Causes of Leaking Roof

Clogged Gutter

Water needs to be drained out from the roof somehow, and if the gutters are clogged up with leaves and debris, the water is not going to go where you want it. To prevent water leaking into vulnerable places, keep gutters free of leaves and debris.

Damaged Underlay

Of course, roof tiles and slates will keep out rainwater. However, there is a chance that strong winds can force rainwater into the gaps or underneath the tiles. This is when the underlay comes into play as it will keep the water away from the gutter. However, with continued exposure to rain, the underlay begins to rot and will not function properly, leading to a leak over time.

Broken Shingles

This is one of the leading causes of leaking roofs. Broken shingles are easier to identify, and it is advisable to verify the integrity of the shingles whenever a major storm occurs. Replacing missing or broken shingles is a common roof repair in San Antonio Texas that won’t cost you much compared to a roof replacement due to leakages, mold growth, or other issues.

Broken Flashing

Flashing helps to seal the joints and other points where water can leak in. If the flashing is broken or faulty, it can lead to potential leaks. Make sure it is sealed properly.


It is one of the main reasons for most roofing problems. Most homeowners tend to overlook their roof until something goes wrong with it. Poor maintenance and ignoring regular roof inspection could cost you more than you want to pay.
