About Roofing Materials
The roofing material used is the Super Galtect from Aijii Industry.
The 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!
Made of SGL steel plate, it is also resistant to rust.
Insulation material is tightly applied from edge to edge of the roofing material, creating a metal plate that integrates steel 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.
Additionally, it has soundproofing properties, reducing the sound of rain.
Moreover, it is lightweight compared to other roofing materials, which reduces the sway during earthquakes, making it a good earthquake countermeasure.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aijii Industry is the most frequently used in our construction achievements, gaining significant attention!

What is the Roof Overlay 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.”
Benefits of the Overlay Method
Since we overlay a “new roof” on the “existing roof,” there is almost no need for demolition work, meaning very little waste is generated.
This is our biggest feature, leading to various benefits.
The only part that requires demolition and waste disposal is the ridge cap, so compared to complete roof replacement, the cost is lower.
In 2004, regulations regarding the concentration of asbestos in raw materials were changed (for more details, please visit the Ministry of Health, Labour and Welfare’s website).
Some building materials used in structures built before 2004 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 period than painting or complete roof replacement. A shorter construction period means lower labor costs, which in turn makes the overall cost lower.
This also reduces the psychological anxiety of having to live in an unusual environment.
If scaffolding is set up, you may experience inconveniences such as difficulty entering and exiting or opening windows. Being able to return to your normal life in a short period is a significant advantage.
Our company specializes in exterior renovation work, but the roof overlay method is the most frequently performed service we offer. We are very grateful that we have been continuously engaged in roof overlay projects without interruption.
