What is a Skylight (Top Light)?
This page will explain the costs associated with skylight repairs and replacements!
A skylight is a window installed on the roof, as shown in the photo above. Its main purposes are to provide natural light and ventilation, and it is said to have about three times the lighting effect compared to wall windows.
While there are various benefits such as natural light and ventilation, there are also drawbacks like the risk of leaks, condensation, and summer heat.
Maintenance may be required due to deterioration or issues such as leaks or broken glass.
Below, we will introduce the methods and costs for skylight repairs.

We will explain the repair and renovation methods for skylights by categorizing them into patterns!
1. Skylight Replacement and Overlay Method
Skylight Replacement (FCM Overlay Method)
There are various methods for skylight replacement and overlay, including “Oversize Method,” “Small Size Method,” and “Same Size Replacement,” and costs vary depending on the materials and methods used.
Whether to replace the skylight during roof replacement or overlay work also significantly affects the cost.
By performing skylight replacement work in conjunction with roof work, costs can be significantly reduced.
The main skylight manufacturer we handle is VELUX Japan Co., Ltd.!
2. Skylight Glass Replacement
Skylight Double Glass Replacement
Over time, the glass in skylights may develop cracks or breaks due to aging.
Even if the glass is broken, it is possible to replace just the glass.
For skylight glass, we recommend double-glazed structure glass for insulation and condensation prevention.
3. Skylight Leak Repair & Waterproof Tape Replacement
Galvalume Steel Cap “JFE Steel / Kiwami MAX”
One common cause of leaks from skylights is water intrusion around the glass.
In many cases, sealing repairs around the glass and replacing the waterproof tape after detaching the frame can stop the leaks.
This type of skylight repair is relatively inexpensive compared to other repairs.
4. Skylight Surrounding Metal Replacement
Skylight Metal Work
There is a metal flashing installed around the skylight to drain rainwater that has entered the interior to the outside.
If this flashing deteriorates, deforms, or develops holes, it can lead to leaks.
The skylight metal work involves replacing the metal flashing around the skylight.
This can also be done in conjunction with roof overlay or re-roofing work, significantly reducing costs.
5. Skylight Removal Work
Skylight Removal Work
Some individuals who have experienced leaks from their skylights may wish to have them removed.
The cost can vary significantly depending on whether this is done in conjunction with roof overlay or re-roofing work.
Additionally, the cost will also fluctuate based on whether interior work is performed at the removal site.

Examples of Skylight Replacement Work
We would like to introduce examples of work done during skylight replacement (FCM cover method)!
1. Partial Demolition of Existing Skylight
We will partially remove the existing skylight. We will take precautions to prevent debris from falling indoors before proceeding with the work!
2. New Base Frame and Waterproof Sheet
We will assemble a wooden frame to match the size of the new skylight. A waterproof sheet will be wrapped around the wooden frame to prevent leaks!
We will also process the waste board metal work around the skylight!
3. Installation of New Skylight
Finally, we will install the skylight itself, completing the work!
The skylight used is a flat series from Velux Japan!
