Roof Replacement Construction Procedure

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 workmanship 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.
When installed, insulation is applied even to the parts 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, which reduce the sound of rain.
Being lighter than other roofing materials, it also minimizes the swaying during earthquakes, providing earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aijii Industry is the most frequently used material in our projects, gaining significant 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 layered, 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 material is generated.
This is the biggest feature and leads to various advantages.

The only parts that require demolition and waste disposal are the ridge cap, so compared to 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’s website).
Some building materials used in constructions completed before 2004 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 feel free to consult with us.

Additionally, the work 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 makes the overall cost lower.
The psychological anxiety of having to live in an unusual environment is also reduced.
When 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 period is a significant advantage.

Our company specializes in roofing work, and the roof overlay method is the most frequently performed type of work we do. We are very grateful that we are continuously able to carry out roof overlay projects without interruption.
