These are photos from the Galtect roof overlay construction!
The construction period is two days.
Galtect is recommended for those who feel that the second floor is hot because it contains insulation material!
We recommend doing the construction before summer!!

About the roofing material used

The roofing material used is Aijii Industrial’s Super Galtect.
Super Galtect comes with a manufacturer warranty of 15 years for the coating and 25 years for perforation.
Our company also provides a 10-year construction warranty!

Additionally, it is made of SGL steel plate, which is resistant to rust.
Insulation material is tightly applied from edge to edge of the roofing material, creating a metal plate that integrates the steel plate and insulation.
When installed, insulation is applied even to the parts where the roofing materials overlap, and the surface is coated with a highly heat-reflective paint, allowing for a cool summer and a warm winter.
It also has soundproofing properties, reducing the sound of rain.
Moreover, it is lighter compared to other roofing materials, which reduces the sway during an earthquake, making it a good earthquake countermeasure.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and our company’s construction achievements show that Aijii Industrial’s Super Galtect is the most popular and highly regarded!

What is the Roof Overlay (Cover Method)?

The roof overlay method involves leaving the current roof almost as it is and placing a new roof on top of it, effectively covering it.
Literally, it is a method of covering a roof with another roof. Therefore, the roof becomes double-layered. Since the roof is laid on top of another, it is also referred to as “overlapping roofing.”

Advantages of the Overlay Method

Since we overlay “new roofs” on the “current roof,” demolition work is almost unnecessary, meaning that very little waste is generated.
This is the biggest feature, leading to various benefits.

The only parts that require demolition and waste disposal are the ridge cap, making it more cost-effective compared to complete roof replacements.
In 2004, regulations regarding the concentration of asbestos in raw materials were changed (for details, please see the Ministry of Health, Labour and Welfare’s website below).

Building materials used in structures constructed before 2004 may contain asbestos. Asbestos-containing materials are difficult to demolish due to their high environmental impact, and the costs for demolition and waste disposal are also high. The roof overlay method, which generates almost no waste, is ideal for such roofs.

Some may wonder, “Is it safe to live in a building that uses asbestos-containing materials?” but rest assured. As long as there is no destruction or crushing, it will not disperse into the air.
If you are unsure about the type of roof on your home, please feel free to consult us.

Additionally, we can complete the work in a shorter time frame compared to painting or complete roof replacements. A shorter construction period means lower labor costs, which in turn reduces expenses.
This also alleviates the psychological anxiety of having to live in an unusual environment.
When scaffolding is set up, there may be inconveniences such as difficulty entering and exiting or opening windows. Being able to return to normal life in a short period is a significant advantage.

Our company specializes in roofing work, but roof overlay method projects are the most frequently performed jobs we undertake. We are very grateful that we consistently have ongoing roof overlay method projects.
