Leaking Skylight? When to Repair and When to Replace

A leaking skylight can quickly go from a minor annoyance to a major problem, turning your bright, sunlit space into a source of stress. Whether it’s a steady drip during storms or subtle signs of water damage, knowing how to handle a leaking skylight is crucial.

The question is: if your skylight leaks when it rains, should you try to repair the leak, or is it time to replace the entire unit? Each option has its pros and cons, and making the right choice depends on factors like the age of your skylight, the severity of the damage, and your long-term goals for your home.

Skylight Leak: Repair vs Replace

If your skylight leaks when it rains, the first step is identifying the reason. Our suggestions below are common cases we’ve experienced in our years of work, but each instance should be evaluated by a professional before taking any action.

Here are some common causes and whether you should repair or replace:

Improper Installation: Replace

If your skylight was installed incorrectly (improper fit, too flat of an angle, etc), it may never seal properly, leading to persistent leaks and structural vulnerabilities. In these cases, roof skylight replacement is often the only way to ensure a long-term fix, as the issue stems from the installation itself.

Faulty Flashing: Repair

Flashing is the metal or plastic barrier that helps seal your skylight to the roof. If it’s misaligned, corroded, or damaged, targeted skylight leak repairs can often restore its function without needing to replace the skylight.

Cracked or Damaged Glass: Replace

A crack in the glass compromises the integrity of the skylight, allowing water to drip through when it rains. Roof skylight replacement is typically the best solution to ensure safety and prevent future leaks.

Sealant Deterioration: Repair

Over time, the sealant around your skylight can break down due to weather exposure. Reapplying or replacing the sealant is a straightforward and effective fix for a leaking skylight.

General Wear and Tear: Replace

Skylights have a lifespan of about 10–15 years. If yours is nearing the end of its life or showing multiple signs of aging—like discoloration, water pooling, or structural damage—roof skylight replacement is the smarter choice.

Why Do You Need to Fix a Skylight that Leaks When It Rains?

A leaking skylight may seem like a minor inconvenience, but the consequences can escalate quickly if not addressed properly. Here are common types of damage that can result from ignoring skylight leaks when it rains:

Mold and Mildew Growth: If a skylight leaks when it rains, it can create a moist environment where mold and mildew thrive, potentially causing respiratory issues and health problems for your family.
Rotting of Structural Components: Persistent water intrusion can lead to the rotting of roof sheathing, joists, or even the surrounding drywall, weakening the structural integrity of your home.
Insulation Damage: Wet insulation loses its effectiveness, reducing your home’s energy efficiency and driving up heating and cooling costs.
Electrical Hazards: Water dripping near electrical outlets, wiring, or light fixtures can pose a serious fire hazard and endanger the safety of your home.
Damaged Flooring and Furniture: Leaks that go unnoticed can lead to water pooling, causing warping, staining, or other damage to flooring, carpets, and nearby furniture.
Increased HVAC Costs: A damaged skylight may allow air to escape, overworking your HVAC system to maintain a consistent temperature, increasing your energy bills.
Exterior Damage: Persistent leaks can seep into the roofing or siding near the skylight, compromising the exterior of your home and requiring expensive repairs.
Unpleasant Odors: Stagnant water and mold growth can lead to musty, unpleasant smells that linger and diminish your home’s comfort and air quality.

Fixing a leaking skylight promptly is essential to protect your home and your health. If you’ve noticed signs of a leak, don’t wait—contact a professional to ensure the problem is resolved before it gets worse!

We love our new OKNA 800 series windows! We did a total house replacement and couldn't be happier. Lonnie was great to work with during the pre-installation period, and Jeff, Jared and Ken did an awesome job installing the windows, and keeping all the work areas clean and organized. I would highly recommend these windows and using Choice Home Remodeling!

Response from the owner:Thank you for the review Jewel! We love the Okna windows too. We are glad to hear of your positive experience with our team and products.

Choice replaced all the windows in my house and I could not be happier. The workers showed up both days on the time they said they were going to. When they finished the job, you could not even tell they were there. Very happy with the windows. You can tell they really care.

Response from the owner:Jesse, thank your for your review. We take pride in our work and the products we offer, glad to hear this was able to come across in your experience with us.

Excellent company, outstanding service. We had new windows installed last year and recently 2 storm doors. All are great products and we are very satisfied. The customer service we received was always prompt and reliable. Thank you Choice!

Response from the owner:Mary Beth, thank you for your review. It has been a pleasure working with you on these projects!

Great work!! Friendly, professional and honest. I would recommend and will use again.

Response from the owner:Thank you Paul! These March winds should be no match for your new storm door. We look forward to working with you in the future.
