In-house Waste Separation

During skylight construction, various waste materials such as roofing materials, glass, and wood are generated.

Advantages and Disadvantages of Skylights

Advantages of Skylights

High Light Transmission

First, the advantage of skylights is their high light transmission.
When natural light enters the room abundantly, it creates a sense of openness, making it feel pleasant.

Energy savings

This also contributes to high light transmission, allowing you to save on electricity costs due to the presence of natural light. As a result, the need to turn on electric lights during the day decreases, making it suitable for energy conservation.

Good ventilation

By installing a skylight, you can open and close it, which improves ventilation.
Warm air rises, enhancing airflow.

High privacy

In areas where houses are closely built, large windows can expose the interior of your home. However, with skylights, since they are installed on the roof, your privacy is maintained.

Disadvantages of skylights

Risk of leaks

The biggest concern when installing a skylight is the risk of leaks. Since it involves opening up the roof, there is always some risk of water leakage.

However, with proper installation and regular maintenance, the risk can be minimized significantly.

Regular maintenance is necessary

Skylights need maintenance every 5 to 10 years to prevent leaks. While maintenance can be a hassle, it is recommended to perform it regularly to avoid damage to the interior and wooden parts caused by leaks.

Noise from rain can be bothersome

Since skylights are installed directly on the roof, the sound of raindrops hitting the glass can easily be transmitted indoors. This can be particularly noticeable during heavy rain or storms.

However, this is not the case for all skylights. Choosing double-glazed glass or products with high sound insulation can reduce the noise from rain.

Background to the Construction

Due to cracks in the skylight glass, we received a request to replace the skylight glass in conjunction with the roof overlay work.

Skylight Glass Replacement Work – Construction Procedure

1. Remove the components around the skylight

First, we will remove the cover materials and securing materials around the skylight. These materials will be reused, so we will take them off carefully.

2. Protection

We will protect the area around the skylight indoors.
We will take measures to ensure that no debris falls inside.

3. Removal of Existing Glass

Next, after removing the cover materials, we will take out the existing glass.

4. Installation of New Glass

Once the existing glass is removed, we will install the new glass. We will carefully install it to avoid breaking, just as we did during removal.

5. Waterproofing Treatment

When replacing the skylight glass, waterproofing treatment may be necessary.
We will perform waterproofing around the glass using butyl tape and other materials.

6. Restoration of Materials and Sealing

We will reattach the covers and fasteners that were holding the glass in place.
It is important to ensure that the installation method matches the type of skylight used, as improper installation could lead to leaks. We will check that the fasteners are securely in place.
We will perform waterproofing treatment around the frame with sealing.

How to Choose a Skylight Contractor

There are many skylight contractors in Kiyose City, and you may be unsure which one to choose.

Therefore, when requesting skylight replacement work or leak repairs, it is important to check the following 5 points.

By checking the above 5 points, you will be able to choose a reliable contractor.

They have extensive experience in skylight work.

Skylight contractors often have websites that showcase their work experience.

Additionally, if they provide detailed explanations of repair work with photos, it can give you peace of mind as a reference when you request repairs.

If you are concerned about whether the contractor you are about to hire will respond properly, choose one with ample repair experience.

It can also be effective to refer to reviews on Google or review sites when looking for skylight contractors!
If there are many negative reviews or no reviews at all, it may be wise to refrain from hiring them.

Kakeru Koumuten Co., Ltd. specializes in exterior work, so we receive many requests for skylight replacement work.

Confirm if they can handle roofing work.

Since skylights are installed on roofs, roofing work is often involved.
If the contractor lacks knowledge about roofs or cannot handle roofing work, it could lead to leaks after installation or result in high construction costs, leading to potential troubles.

Moreover, since skylight replacement or removal may require partial roof dismantling or restoration, performing roof overlay work or re-roofing together can significantly reduce costs!

Our company specializes in roofing work, so we can propose the optimal plan tailored to your needs for roofing work associated with skylight installation.

Check for warranties and after-sales maintenance

When choosing a skylight contractor, make sure to check for warranties.

If a leak occurs after the skylight installation, having a leak warranty from the contractor ensures that repairs can be made at no cost, providing peace of mind!
Additionally, a company that offers a warranty is a sign of confidence in their work, which can serve as a criterion for selecting a contractor!

Warranty periods vary by contractor and the nature of the work, but typically range from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.

Moreover, some contractors offer after-sales services in addition to warranties, so be sure to check if the contractor you are considering has warranties and after-sales services.

Kakeru Koumuten Co., Ltd. sends out annual direct mail as part of our after-sales maintenance, allowing for yearly inspections.
For simple repairs like partial sealing, we provide services at no charge.

Obtain estimates from multiple contractors (at least three)

When requesting skylight installation, be sure to obtain estimates from multiple contractors.

Even for the same repair or replacement work, costs and warranties or after-sales services may differ between contractors.

Additionally, obtaining multiple estimates makes it easier to negotiate prices.

To request your preferred contractor at a lower price, obtaining estimates from multiple contractors is essential.

When comparing estimates, consider not only the cost but also
“Items in the estimate”
“Materials and quality, such as glass”
“Confirmation of the process”
and make a detailed comparison! If the quality of auxiliary materials is low or if steps are skipped, costs can be reduced, so avoid making decisions based solely on price!

Check if the company performs the work in-house

There are various construction methods for skylight repair plans, including full replacement, roof overlay (cover method), and partial repairs!
The plan details will vary depending on the actual state of deterioration and the customer’s preferences.

If you choose a contractor that completely outsources skylight repair work, they may lack knowledge and experience, leading to proposals for repairs in the wrong areas or unnecessary construction. There are cases where customers who want to keep costs down are suggested to replace the skylight, even though a partial repair would suffice.

Additionally, since they investigate and then request subcontractors, it incurs extra time and costs.
By having knowledge and experience and performing the work in-house, we can provide responsible construction while keeping costs down.

Moreover, with contractors that outsource work, one of the disadvantages is that their response to post-construction troubles or emergencies tends to be slow.
