Kanagawa Prefecture | Konan-ku, Yokohama | K’s Residence: We performed roof renovation and leak prevention measures!

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 (roof repair) in Konan-ku, Yokohama, Kanagawa Prefecture.
The work involved a roof overlay (cover method) using Super Galtect!
We implemented leak prevention measures through the roof overlay work!
Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.

Roof Overlay Construction Procedure

The roofing material used is the Super Galtect from Aijii Industry.
The Super Galtect comes with a manufacturer warranty of 15 years for the coating and 25 years for perforation.
We also provide a 10-year construction warranty!
Made of SGL steel plate, it is resistant to rust. SGL steel plates have higher durability than Galvalume steel plates!
Insulation material is tightly applied from edge to edge of the roofing material, creating a metal plate that integrates steel plate and insulation.
When installed, insulation is applied even to the parts where the roofing materials overlap, and the surface is coated with a high heat-reflective paint, allowing for a cool summer and a warm winter.
Additionally, it has soundproofing properties, reducing the sound of rain.
Moreover, it is lightweight compared to other roofing materials, which reduces the sway during earthquakes, making it a good earthquake countermeasure.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and among our construction achievements, Aijii Industry’s Super Galtect is the most popular and highly regarded!

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 layered, 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 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, so compared to complete roof replacement, the cost is lower.
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).
Some building materials used in structures built 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, 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 expenses more affordable.
This also reduces the psychological anxiety of having to live in an environment that is different from usual.
When scaffolding is set up, there may be inconveniences such as difficulty in entering and exiting or being unable to open windows. Being able to return to normal life in a short period is certainly a significant advantage.

Our company specializes in roofing work, and 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.
