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.
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 parts that require demolition and waste disposal are typically the ridge cap, making it more cost-effective compared to complete roof replacement.
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).
Some building materials used in structures built 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.

You may be wondering, “Is it safe to live in a building that uses asbestos-containing materials?” 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 than painting or re-roofing. The fact that the construction period is short means that labor costs will also be lower, which in turn makes the costs more affordable.
This also reduces the psychological anxiety of having to live in an environment that is different from usual.
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 certainly a significant advantage.

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

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.
We also provide a 10-year construction warranty!
Made of SGL steel plate, it is resistant to rust.
Insulation material is thoroughly 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 highly heat-resistant paint, allowing for a cool summer and a warm winter.
Additionally, it has soundproofing properties, which also reduces the sound of rain.
Moreover, it is lighter compared to other roofing materials, which reduces the sway during earthquakes, contributing to earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aijii Industrial is the most frequently used in our construction achievements and has garnered significant attention!
