Roof Replacement Construction Procedure

1. Removal of Existing Roof Ridge Metal

We will dismantle the unnecessary existing roofing materials (ridge metal, snow guards) for the overlay method! The durability of wooden purlins is about 10 to 15 years. Exceeding the durability period can lead to corrosion and discoloration, resulting in the ridge metal coming loose or being blown away.

2. Roofing Installation (Waterproof Sheet)

3. Component Processing (Curly Patterns, Eaves, Valleys)

4. Main Body Construction (Aijii Kogyo/Super Galtect)

5. Ridge Sheet Metal Processing and Sealing

6. Cleaning

About Roofing Materials

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.
Our company also provides a 10-year construction warranty!
It is made of SGL steel plate, which is also resistant to rust.
The insulation material is tightly applied from end to end of the roofing material, creating a metal sheet that integrates both 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 a highly heat-reflective paint, allowing for a cool summer and warm winter experience.
Additionally, it has soundproofing properties, which help reduce the sound of rain.
Furthermore, it is lighter compared to other roofing materials, which reduces the sway during earthquakes, providing earthquake resistance as well.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aijii Industrial is our most frequently used material, gaining significant attention in our construction achievements!

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 to cover 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.”

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 and leads to various benefits.

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 details, please refer to the Ministry of Health, Labour and Welfare website).
Building materials used in structures constructed before 2004 may contain asbestos. Asbestos-containing materials are difficult to dismantle due to their high environmental impact, resulting in high costs for both demolition 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 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 us.

Additionally, we can complete the work in a shorter time frame compared to painting or complete 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 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 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.
