About the Roofing Materials Used

The roofing material used is the Super Galtect from Aijii Industrial.
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!

Additionally, it is made of SGL steel plate, which is resistant to rust.
Insulation material is thoroughly 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 high heat-reflective paint, allowing for a cool summer and a warm winter.
Moreover, it has soundproofing properties, which also reduce the sound of rain.
Being lighter than other roofing materials, it reduces the sway during earthquakes, providing earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aijii Industrial is the most frequently used in our construction achievements, gaining significant attention!

What is the Roof Overlay (Cover Method)?

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

Advantages of the Overlay Method

Since a “new roof” is placed over the “current roof,” demolition work is almost unnecessary, meaning that very little waste is generated.
This is its most significant feature, leading to various advantages.

The only part that requires demolition and waste disposal is the ridge cap, making it more cost-effective compared to complete roof replacement.
In 2004, regulations regarding the concentration of asbestos in raw materials were changed (for details, please refer to the Ministry of Health, Labour and Welfare 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 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 consult us.

Additionally, the construction can be completed in a shorter period compared to painting or complete roof replacement. A shorter construction period means lower labor costs, which in turn makes the overall cost cheaper.
The psychological anxiety of having to live in an unusual environment is also reduced.
If scaffolding is set up, you may experience inconveniences such as difficulty entering and exiting or not being able to open windows. Being able to return to normal life in a short time is a significant advantage.

Our company specializes in roofing work, and the roof overlay method is the most frequently performed type of work we undertake. We are very grateful that we have been continuously engaged in roof overlay projects without interruption.
