Leaking Skylight? When to Repair and When to Replace

Leaking Skylight Repair and Replacement Solutions

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!

Choice Windows, Doors & More, Inc.4.8

I recently hired Choice to replace 12 windows and a sliding glass door in my home, and they did excellent work. I want to provide this review for anyone in the Lancaster County area looking for new windows: save yourself some trouble and just hire Choice. The original windows and sliding door in my house were cheap builder grade units that were ~25 years old and all failing in one way or another. I did my due diligence and requested quotes from five different contractors, including a big box home improvement store and a couple of the national window chains. To make a long story short, Choice was the best price, the best product, and the most comprehensive installation work! Everyone who I worked with at Choice, from the sales, finance, and install teams, was extremely friendly and professional. They installed wonderful, PA-made Okna windows and doors, and they installed them properly; no shortcuts taken (unlike some of the other contractors who I received quotes from). The install team were great; they had all the work done in exactly the time they quoted, and they were very mindful of being as clean as they could. They also informed me that some of the existing windows were installed very poorly, with very little insulation and flashing. They installed the new windows correctly, and the difference was immediate and incredible. I could not be happier with the work they did and the products they provide. The new windows and door at my house are such a huge improvement over the old ones. If you're looking for a contractor for your next home improvement project, look no further!

Response from the owner:Thank you, Devon, for the wonderful review! We work hard to provide not only quality products and expert installation, but also an easy and helpful experience from the very first contact. We truly appreciate you taking the time to share about your experience with us!

Choice Remodeling was professional from start to finish. They were prompt, informative and did excellent work replacing the windows in our whole house. I would recommend them for any job!

Response from the owner:Thank you Molly for taking the time to leave us a review. We appreciate your referral and are happy we were able to provide a positive experience for you!

The new storm door with roll up screen and the new sliding door for our deck look wonderful. The sales person, Tim Simmers, was great to work with and the men doing the installation work were terrific. I will be using Choice Home Remodeling for all my future projects!

Response from the owner:Thank you Daniel for your review. We appreciate you taking the time to share your experience and look forward to partnering with you in the future!

I can't rave enough about my experience with Choice Home Remodeling! After a long search for a team that was not only professional and knowledgeable but also friendly and patient, I found exactly what I was looking for. Tim, Nate, and the entire crew did an outstanding job installing a new sliding door in place of an existing bay window on my block-style home. From start to finish, they answered all of my questions with confidence, kept me informed throughout the process, and completed the work with exceptional care and craftsmanship. Choice Home Remodeling earns my highest recommendation!

Response from the owner:Karen, thank you for your five star review and kind words. It was a pleasure working with you and we are happy to hear you felt the same way! Please let us know if there is any thing else we can partner with you on in the future.
