Kanagawa Prefecture | Kawasaki City, Saiwai Ward | Mr. M’s Residence: We carried out 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 project in Saiwai Ward, Kawasaki City, 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.
Our company also provides 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 end to end of the roofing material, creating a metal sheet that integrates the 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 warm winter experience.
Additionally, it has soundproofing properties, reducing the sound of rain.
Moreover, it is lightweight compared to other roofing materials, which minimizes the sway during an earthquake, contributing to earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and among our construction achievements, the Super Galtect from Aijii Industry 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 laid over the existing one, 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 more details, please visit the Ministry of Health, Labour and Welfare’s website).
Building materials used in structures constructed before 2004 may contain asbestos. Asbestos-containing materials are difficult to demolish due to their high environmental impact, and both demolition and waste disposal costs can be 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.
The psychological anxiety of having to live in an unfamiliar environment is also reduced.
When scaffolding is set up, you may experience inconveniences such as difficulty entering and exiting or trouble opening windows. Being able to return to your normal life in a short period is a significant advantage.

Our company specializes in roofing work, and the roof overlay (cover method) is the most frequently performed project we undertake. We are very grateful that we have been able to continuously carry out roof overlay (cover method) projects without interruption.
