About Roofing Materials

The roofing material used is the Super Galtect by Aijii Industrial.
The Super Galtect comes with a 15-year paint warranty and a 25-year hole warranty from the manufacturer.
We also provide a 10-year construction warranty!
Made of SGL steel plate, it is 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 areas where the roofing materials overlap, and the surface is coated with a highly 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, providing earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aijii Industrial is our most frequently used material, receiving 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, 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, 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 details, please visit the Ministry of Health, Labour and Welfare website).
Some building materials used in structures built before 2004 contain asbestos. Because materials containing asbestos have a high environmental impact, dismantling them is also difficult, and both the dismantling and waste disposal costs are high. The roof overlay method, which produces almost no waste, is ideal for such roofs.

You may be wondering, “Is it safe to live in a building that uses materials containing asbestos?” 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 us.

Additionally, the construction can be completed in a shorter time frame compared to 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, but the roof overlay method is the most frequently performed type of work we undertake. We are very grateful that we are continuously able to carry out roof overlay projects without interruption.
