Tama-ku, Kawasaki City, Kanagawa Prefecture | We performed roof overlay work using Ridgeway!

Hello!
I am Yamanaka from Kakeru Koumuten Co., Ltd., a specialist in roof renovations, exterior painting, and exterior renovations located in Aoba-ku, Yokohama, Kanagawa Prefecture!
This is a case study of a roof renovation project in an apartment in Tama-ku, Kawasaki, Kanagawa Prefecture.
The work involved a roof overlay (cover method) (Ridgeway)!
We were also entrusted with the exterior painting work!
I will also upload a case study of the exterior painting work, so please take a look if you are interested!
Thank you very much for choosing Kakeru Koumuten Co., Ltd. among many contractors.

Tama-ku Apartment Cover Work Construction Photos

The roofing material used is Ridgeway from Asahi Fiberglass.
Ridgeway comes with a 10-year manufacturer warranty.
Since it uses natural stone with baked-on paint on 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 rain noise.
Moreover, being a lightweight roofing material, it is also strong against earthquakes and has seismic resistance.
You can choose from five colors: Dual Black, Dual Brown, Harvard Slate, Vintage Green, and Earthstone Cedar.

The cover work with Harvard Slate turned out exceptionally well!
The customer was very satisfied, and I was also very happy!
Thank you very much!

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 another, it is also referred to as “overlapping 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 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, making it more cost-effective compared to re-roofing.
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 website).
Some building materials used in structures constructed before 2004 contain asbestos. Asbestos-containing materials are difficult to dismantle 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 if it is safe to live in buildings that use 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 period than painting or re-roofing. A shorter construction period means lower labor costs, which in turn makes the costs more affordable.
The psychological anxiety of having to live in an unusual environment is also reduced.
When scaffolding is erected, 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 can be considered a significant advantage.

Our company specializes in roofing work, but the roof overlay method is the most frequently performed work we undertake. We are very grateful that we are continuously able to carry out roof overlay method work without interruption.
