Kawasaki-ku | Roof Overlay Work

The roofing material used this time is Nichiha Corporation’s Yokodana Roof S.
Yokodana Roof S comes with a manufacturer’s warranty of 15 years for the coating, 20 years for red rust, and 25 years for perforation.
It is a high-performance metal insulated roof made by integrally molding metal steel plates (high-durability painted Galvalume steel plates), insulation (rigid urethane foam), and aluminum laminated backing material.
It is lightweight, earthquake-resistant, and exhibits excellent insulation performance throughout the year, achieving long maintenance due to its high durability.

The construction period was 4 days! Thank you very much!

What is the Roof Overlay Method?

The roof overlay (cover method) involves leaving the current roof almost intact 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 laid over itself, it is also referred to as “overlapping roofing.”

Advantages of the Cover Method

By placing the “new roof” over the “current roof,” there is almost no need for demolition work, meaning that very little waste material 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 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 cover 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, it can be completed 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, there may be inconveniences such as difficulty entering and exiting or opening 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 are continuously able to carry out roof overlay (cover method) projects without interruption.
