About the Roofing Material
The roofing material used is Ridgeway by Asahi Fiberglass.
Ridgeway comes with a 10-year manufacturer warranty.
Since it uses natural stone that is baked onto the surface, it is a roofing material that does not require painting, which helps reduce maintenance costs!
Additionally, because it uses fine natural stones on the surface, you won’t be troubled by rain noise.
Moreover, it is a lightweight roofing material, making it strong against earthquakes and providing seismic resistance.
* After installation, some of the surface decorative stones may fall off for about a week, but this does not indicate a quality issue.

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, effectively covering it.
Literally, it is a method of covering a roof with another roof. Therefore, the roof becomes double-layered. It is also referred to as “重ね葺き” (kasanebuki) because the roofs are layered.
Advantages of the Overlay Method
Since a “new roof” is placed over the “current roof,” demolition work is almost unnecessary, meaning very little waste is generated.
This is the biggest feature and leads to various advantages.
The only part that requires dismantling and waste disposal is the ridge cap, so compared to a 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 dismantle due to their high environmental impact, resulting in high costs for both dismantling 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 with us.
Additionally, the construction can be completed in a shorter timeframe than painting or a full roof replacement. A shorter construction period means lower labor costs, which in turn makes the overall cost lower.
This also reduces the psychological anxiety of having to live in an unusual environment.
If scaffolding is set up, you may experience 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, but the roof overlay method is the most frequently performed service we offer. We are very grateful that we have been continuously engaged in roof overlay projects without interruption.
