About the Roofing Material 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.
We also provide a 10-year construction warranty!
Additionally, it is made of SGL steel plate, which is resistant to rust.
The insulation material is tightly applied from end to end 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-resistant paint, allowing for a cool summer and warm winter experience.
Moreover, it has soundproofing properties, reducing the sound of rain.
Being lighter than other roofing materials, it also reduces the sway during earthquakes, providing earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and our company’s construction achievements show that the Super Galtect from Aijii Industrial 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 over itself, it is also referred to as “overlapping roofing.”

Benefits of the Roof Overlay Method

Since a “new roof” is placed over the “existing roof,” demolition work is almost unnecessary, meaning that very little waste is generated.
This is the biggest feature, leading to various benefits.

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

Building materials used in structures constructed before 2004 maycontain 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 if it’s safe to live in buildings that use 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 with us.

Additionally, the construction can be completed in a shorter time frame compared to painting or complete roof replacement.A shorter construction period means lower labor costs, which in turn makesthe expenses more affordable.
This also reduces 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 being unable to open 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 have been continuously engaged in roof overlay projects without interruption.
