Hello!
This is 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 an exterior renovation project in Fujimino City, Saitama Prefecture.
There are several types of exterior renovations, and this project involves a roof replacement (Ridgeway)!
We implemented measures against leaks due to the roofing work!
On this page, I will explain the actual results of the work done by Kakeru Koumuten!
Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.
Roof Replacement Construction Procedure
1. Dismantling Existing Roofing Materials
Tile battens are wooden materials used to hook the tiles.
2. Installing New Sheathing Boards
3. Roofing Installation (Waterproof Sheet)
The roofing used in
It is made of modified asphalt roofing material, which is said to have double the durability of regular asphalt roofing.
With a solid roofing installation serving as the first line of waterproofing, there will be no leaks!
We will securely attach it to ensure it does not blow away.
4. Main Body Construction (Aiji Kogyo/Super Galtect)
After processing the accessories in
Once we have installed it up to the ridge, we will set up the necessary materials for fixing the ridge board, known as the kanban. There are types of kanban made from cedar and resin, and this time we used cedar!
5. Ridge Cap Processing and Sealing at Various Locations
We will process and install the
At the wall edge, we will process and install a component called rain stop sheet metal.
We will use stainless steel nails and screws that are resistant to rust!
6. Cleaning
The roofing material used is 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 stone 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.

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. 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 its most significant feature, leading to various advantages.
The only part that requires demolition and waste disposal is 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’s website).
Building materials used in constructions completed before 2004 may contain asbestos. Asbestos-containing materials are challenging 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, we can complete the work in a shorter time frame than painting or re-roofing. 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 environment that is different from usual is also reduced.
If scaffolding is erected, there may be inconveniences such as difficulty in entering and exiting or opening windows. Being able to return to normal life in a short period is certainly a significant advantage.
Our company specializes in roofing work, but the roof overlay (cover method) is the most frequently performed service we offer. We are very grateful that we have been continuously engaged in roof overlay (cover method) projects without interruption.
