The Dangers of a Leaking Skylight: Why You Need To Address the Problem Now

by | Aug 9, 2023 | Skylights

Skylights are a wonderful addition to any home or building, allowing natural light to flood in and enhancing the aesthetic appeal of your space. Additionally, skylights create a connection and openness to the outdoors, which is a great way for you to observe and marvel at the wonders of the world outside. However, when a skylight is leaking, it can quickly turn from a beautiful feature into a source of significant problems. 

In this article, we will explore the dangers associated with a leaking skylight and emphasize the importance of addressing the issue immediately. 

Signs of a Leaking Skylight

Before we dive into the dangers of a leaking skylight, it’s important to address the signs of this issue

One of the most obvious indications of a leaking skylight is the presence of water stains and discoloration on the ceiling surrounding the window. These unsightly marks not only distract from the appearance of the space but also serve as a clear sign that water is infiltrating through the opening.

Another telltale sign is dripping or pooling water around the skylight itself. So, if you notice water collecting near the edges or corners of your skylight, it is a strong sign that the skylight is leaking and requires immediate attention.

Additionally, mold or mildew growth near the skylight is another red flag. These fungi thrive in moist environments, and a leaking skylight provides the perfect breeding ground for them. When these substances appear, it’s a clear sign that your skylight is leaking. 

On top of these signs, a significant increase in energy bills as a result of air leaks can point to damage to your skylight. 

A leaking skylight will not only lead to potential structural problems but can also pose a risk to the health and well-being of you and your family. 

Structural Damage

The consequences of a leaking skylight go beyond aesthetic and financial issues. Over time, the constant exposure to moisture can weaken the roof decking and framing. This compromises the structural integrity of our entire roof, and, as a result, increases the risk of costly repairs down the line.

Additionally, the presence of water can lead to compromised insulation, resulting in heat loss during colder months and heat gain during warmer months. This puts a strain on your HVAC system, further driving up energy costs. 

If that’s not enough, the excess moisture can cause damage to interior walls and finishes, which will not only destroy the aesthetics of your home but also require complex renovations.

Health and Safety Risks

As mentioned earlier, a leaking skylight creates an environment conducive to the growth of mold and mildew, which is a hazard to your health.

The spores that these fungi release can cause respiratory issues, especially for those with allergies or asthma. When these individuals are exposed to mold spores, they can develop coughing, sneezing, wheezing, and even more severe respiratory problems.

Aside from the internal health hazard, the presence of water on the floor beneath the skylight can create a slippery surface, increasing the physical risk of accidents. Anyone who comes into contact with these water puddles can slip, slide, and fall, leading to unnecessary injuries.

Overall, allowing the water to pool can give rise to various problems and pose electrical hazards, potentially causing electrical shorts and other dangerous situations.

Increased Energy Bills

A leaking skylight can lead to increased energy bills due to air leaks. This is because air leaks can cause drafts and temperature fluctuations. 

Plus, when your skylight is not properly sealed, it allows warm air to escape during the winter and cool air to seep out in the summer. As a result, your heating and cooling systems have to work harder to maintain a comfortable indoor temperature, driving up your energy costs.

That being said, having problems with your skylight can impact the overall energy efficiency of your building.

Importance of Timely Repair

Addressing a leaking skylight promptly is of utmost importance. Doing so can lead to a wide range of benefits.

Preventing Further Damage and Costly Repairs

A leaking skylight is not a problem that will go away on its own. It will likely worsen over time if left unattended. 

For instance, water intrusion can seep into the surrounding areas, causing damage to the roof decking, framing, and insulation. The longer the leak persists, the more extensive the damage can become. What may have initially been a minor repair can escalate into a major structural issue that requires significant repairs or even a full skylight replacement.

By addressing the problem promptly, you can prevent further damage from occurring and save yourself from more extensive damage and costly repairs down the line.

Preserving the Structural Integrity of the Building

Another advantage of addressing the issue promptly is that you preserve the structural integrity of your home. 

Keep in mind that exposure to moisture can weaken the roof decking and framing, leading to sagging, rotting, or even structural collapse. By addressing the issue promptly, you can prevent moisture from seeping further into the roof structure, protect it from deterioration, and ensure its stability. 

Ensuring a Safe and Healthy Living Environment

Finally, repairing the skylight and addressing any water intrusion issues will help prevent mold and mildew growth. As a result, it can safeguard the well-being of the building’s occupants, promote clean indoor air quality, reduce the risk of accidents, and provide a comfortable and secure living space for everyone.
