Roof Overlay Construction Procedure

What is the Roof Overlay Method?

The roof overlay method involves leaving the current roof almost as it is 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 the existing one, 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 its most significant feature, leading to various advantages.

The only parts that require demolition and waste disposal are the ridge caps, 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 visit the Ministry of Health, Labour and Welfare’s 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, resulting in high costs for both demolition and waste disposal. 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?” 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, the construction can be completed in a shorter timeframe compared to painting or complete roof replacement. A shorter construction period means lower labor costs, which in turn makes the overall cost cheaper.
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 your 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 consistently have ongoing projects for roof overlay work.

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!
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 steel 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.
Additionally, it has soundproofing properties, reducing the sound of rain.
Moreover, it is lightweight 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, gaining significant attention!
