Roof Replacement Construction Procedure

About the Roofing Materials Used

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!
Additionally, it is made of SGL steel plate, which is resistant to rust.
Insulation material is tightly 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, reducing the sound of rain.
Being lighter than other roofing materials, it also minimizes the sway during earthquakes, contributing to earthquake resistance.
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 projects, gaining significant attention!

What is the Roof Overlay 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. It is also referred to as “overlapping roofing” since the roofs are layered.

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 parts that require demolition and waste disposal are 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 refer to the Ministry of Health, Labour and Welfare’s website below).

Building materials used in structures constructed before 2004 may contain asbestos. Asbestos-containing materials are difficult to dismantle 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 you have, please feel free to consult with us.

Additionally, we can complete the work in a shorter time frame than painting or re-roofing. A shorter construction period means lower labor costs, which in turn makes the expenses more affordable.
The psychological anxiety of having to live in an unusual environment is also reduced.
When scaffolding is set up, there may be inconveniences such as difficulty in entering and exiting or being unable to open windows. Being able to return to normal life in a short period is a significant advantage.

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