Chiba Prefecture | Kashiwa City | Y Residence: We carried out roof renovation and leak prevention using Ridgeway! Here are the construction examples!

Hello!
I am Yamanaka from Kakeru Koumuten Co., Ltd., a specialist in roofing, exterior painting, and exterior renovations located in Aoba-ku, Yokohama, Kanagawa Prefecture!
This is a case study of a roof renovation in Kashiwa City, Chiba Prefecture.
The work involved a roof overlay (cover method) project (Ridgeway)!

This time, we carried out leak prevention measures through the roof overlay project!
Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.

Roof Overlay Project Procedure

The roofing material used is the Ridgeway from 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, thus reducing maintenance costs!
Additionally, because it uses fine natural stones on the surface, you won’t be troubled by the sound of rain.
Moreover, it is a lightweight roofing material, making it strong against earthquakes and providing seismic resistance.

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 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 installed in layers, it is also referred to as “layered roofing.”

Advantages of the Overlay Method

Since a “new roof” is placed over the “current roof,” there is almost no need for demolition work, meaning that very little waste is generated.
This is the biggest feature and leads to various advantages.

The only part that requires demolition and waste disposal is 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 website).
Some building materials used in structures constructed 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.

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, the construction can be completed in a shorter period 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 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.
