How to fix a skylight leak: A leaky skylight can put the structural integrity of a house in danger and pose a health risk because of the growth of mold in attic. Understanding the many kinds of skylights, and probable leak sources, accurately estimating damage, and deciding between do-it-yourself and professional repairs are all necessary for fixing a leaky skylight, which is an important skill for homeowners and property managers. How to Fix a Leaking Skylight?
Hiring a professional roofer is recommended for significant skylight leaks or if you’re not confident you can handle the task yourself. They possess the knowledge and equipment required to correctly identify and fix the problem. We explore these topics in detail in the advice that follows, enabling you to confidently handle the leak and prevent additional damage to your house.
Types of Skylights
Based on their purposes, skylights can be divided into two categories. It is helpful to comprehend how they operate to determine where and how to fix them. The majority of skylights are built specifically for asphalt shingle roofs; however, when placing them on tile or metal roofs, additional flashing is needed.
Skylights with vents
Opening skylights provide several benefits, including ventilation and lighting. Since skylights can be opened in place of windows, homeowners who have open skylights benefit from increased seclusion.
Additionally, they provide moisture control in places like bathrooms and kitchens where condensation is prone to form. Operable skylights, which are typically located in attics with sloping roofs, serve more as windows than skylights. Similar to a window, they are hinged and must be opened by hand.
Anchored skylights
Fixed skylights primarily provide light control and do not open. Since they are mounted on high ceilings, additional tools might be needed to fix them.
They have a longer lifespan of eight to fifteen years, and if the glass is in good shape, leaks usually happen around the borders of the skylight.
Some reasons for Leaking Skylights and how to seal a skylight leak
Your skylight may not be closing all the way if it is vented, and if it is fixed, the cause could be worn-out seals. The following are some typical causes for leaks in skylights:
An inadequate skylight
If the skylight opens, look for mold or evidence of deterioration in the rubber gasket surrounding the frame. That would suggest that there is moisture seeping between the window casing and the frame and that the skylight isn’t sealing completely. The gasket can be changed to resolve this. Small debris fragments could also be blocking the skylight; clearing them out could halt the leak. During an inspection, you may find moisture surrounding a fractured section of the skylight.
While it is possible to remove the damaged part and repair it, replacing the skylight is typically the best course of action.
faulty flashing on the roof
It is quite likely that the leak is coming from seeping under the flashing, which could be defective if leaks continue after moisture and all other skylight faults are ruled out. Since the source of a roof leak from the top portions of the roof slope is understood, fixing it is simpler. However, since water moves up the roof deck, it could be more difficult to locate the source if it originates from lower portions of the roof.
The physical state of the flashing can be used to identify leaks caused by defective or broken roof flashing. Water can pass through flashing that is cracked or curled.
Roof leaks
If the leak originates from a roof hole, the gap can be closed with roof cement. You may easily fix it yourself or hire a reputable roofing company. If you fix any holes surrounding the seal and the skylight still leaks, there might be another problem. This necessitates expert assistance because regular roof leaks can masquerade as skylight leaks, making diagnosis and treatment more difficult.
The process of condensation
When you examine the skylight, keep an eye out for any indications of moisture on the glass. If it gathers at specific locations, it can appear to be a leak. The temperature and humidity differentials on either side of the skylight cause it to form. The best way to deal with condensation is to let fresh air flow through the house. If the skylight is vented, you can just open it; if it is fixed, you can use a fan.
Additionally, you should look for and clear any debris that may be obstructing the skylight’s weep holes, which are microscopic openings that let water condensation escape.
Professional How to Fix a Leaking Skylight Recommendation
Here are some pointers for identifying the issue and coming up with workable fixes for your skylight/roofing issues.
Sourcing the Leak
The majority of roofing contractors will inform you that the skylight or roof window is the cause of the water between the sash and frame. If the leak occurs between the wall and the reveal or the window, there may be an issue with the installation. That is less likely to occur with an underfelt collar. There is a difference between where water appears and where it drips. The water you see most often comes from a crack or hole that the water found to enter your house. Due to the roof’s ability to absorb and transfer water to an entry point, there are two distinct drip and leak spots.
Installation
The leak you see is an installation problem if your skylight has just been installed.
Flashing Installation
The skylight flashing kit and the installed product must match. Having the right kit stops gaps from forming, which stops leaks. For the kit to work with the roofing system, it must also be the right kind.
Underfelt Collar Installation
Waterproofing installation is a two-step procedure. If water manages to seep in, adding a collar—a breathable membrane—should provide an additional layer of defense. Inadequate installation can result in leaks; if the underfelt isn’t drying properly, the issue may just be dampness.
The consequences of faulty skylights
A malfunctioning skylight puts a home in danger of harm. If you ignore skylight leaks:
Damage to furniture
When your furniture and other household objects come into touch with water, they will get ruined. Any fabric or pillows will have stains and smell musty. Additionally, these circumstances encourage bug invasion and reproduction, some of which can result in allergies.
Leaks in the ceiling
A skylight leak could cause water to collect on the inside of the roof. This may cause the ceiling to droop by producing watermarks on it that resemble circular patches.
In addition to causing interior house damage, leaky ceilings can also cause harm to electronics. Paint chipping can also be caused by water that collects in ceiling pools.
Chipped paint
In addition to leaving stains on the wall, water running down the wall also causes the paint to peel because of the temperature variations. Water seeping into the wall could also make the paint less adherent to the wall. As a result, paint will chip in places, leaving an uneven surface that is vulnerable to mildew growth.
Mold growth
In addition to leaving stains on the wall, water running down the wall also causes the paint to peel because of the temperature variations. Water seeping into the wall could also make the paint less adherent to the wall. As a result, paint will chip in places, leaving an uneven surface that is vulnerable to mildew growth.
Rot development
Wood rots in damp conditions continuously. Water that flows from leaks pools onto wooden floors and structures, and is absorbed by the wood. This loosens the architectonic integrity of your house since the wood will not be able to be held under a supposed weight. Wooden floors sag as well, making your footsteps squeal and creak when you walk across them.

High wind will buckle shingles up and water gets under the sides of the lifted shingles. All of a sudden you may have a huge bill if the roofing subcontractor gets involved, or it may be zero if you can contact the contractor and submit a warranty claim.
