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 resistant to rust.
Insulation material is tightly adhered from edge to edge of the roofing material, creating a metal plate that integrates the steel plate and insulation.
During installation, insulation is applied even to the parts where the roofing materials overlap, and the surface is coated with high heat-reflective paint, allowing for a cool summer and warm winter experience.
Additionally, it has soundproofing properties, reducing the sound of rain.
Being lighter than other roofing materials, it also minimizes shaking during earthquakes, serving as an 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 and is receiving considerable attention!

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 over another, it is also referred to as “overlapping 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 the biggest feature and leads to various advantages.

The only part that requires dismantling and waste disposal is the ridge cap, so compared to a full 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 website).
Some building materials used in constructions completed before 2004 contain asbestos. Asbestos-containing materials are difficult to dismantle due to their high environmental impact, resulting in high costs for both dismantling and waste disposal. 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 they are not destroyed or crushed, they will not disperse into the air.
If you are unsure about the type of roof on your home, please feel free to consult with us.

Additionally, we can complete the work in a shorter time frame than painting or full roof replacement. A shorter construction period means lower labor costs, which in turn reduces the overall cost.
This also alleviates the psychological anxiety of having to live in an unusual environment.
When 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 roofing work, and the roof overlay method is the most frequently performed service we offer. We are very grateful that we are continuously able to carry out roof overlay projects without interruption.
