Hello!
I am Yamanaka from Kakeru Koumuten Co., Ltd., a specialist in roofing, exterior wall painting, and exterior renovations located in Aoba-ku, Yokohama, Kanagawa Prefecture!
This is a case study of a roof renovation in Midori-ku, Yokohama.
There are several types of roof renovations, and this project involves a roof overlay (Super Galtect) work!
We implemented measures against leaks through the roofing work!
The existing roof had asolar panel installed, so we also performed the removal and reinstallation!!
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 Overlay & Solar Panel Removal Procedure
1. Temporary Disassembly of Existing Panels
The base brackets and racks will be replaced with those specifically for Galtect.
2. Installing Roofing (Waterproof Sheet)
This is a modified asphalt roofing material, which is said to have double the durability of regular asphalt roofing.
If the roofing is properly installed as a primary waterproofing measure, it will not leak!
We will ensure it is securely attached so it won’t blow away.
3. Custom Fabrication (Curlicue, Valley, Eaves)
The materials used for the custom fabrication are specifically for Galtect and are made of the same material, SGL steel plate.
4. Main Construction (Aiji Kogyo/Super Galtect)
Once the roofing is completed to the ridge, we will install a necessary material called a “nail board” to secure the ridge cap. There are types of nail boards made of cedar and resin, and this time we used a resin type!
The resin type is expected to have three times the durability of the cedar type!
5. Ridge Cap Fabrication & Sealing at Various Locations
For the wall edges, we will process and install a component called rain stop metal.
We use stainless steel nails and screws that are resistant to rust!
6. Solar Panel Installation
We will also conduct a thorough power check, and the work is complete!
I felt relieved that the power check was done properly (laughs).
7. Cleaning
The work is now complete!
We also explain about the installation and removal of solar panels here!
The roofing material used is Aijii Industrial’s Super Galtect.
Super Galtect comes with a 15-year paint warranty and a 25-year hole warranty from the manufacturer.
Our company also provides a 10-year construction warranty!
Made of SGL steel plate, it is resistant to rust.
Insulation material is tightly applied from edge to edge of the roofing material, creating a metal plate that integrates steel 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.
Being lighter than other roofing materials, it also minimizes the sway during earthquakes, making it a good earthquake countermeasure.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and Super Galtect from Aijii Industrial is the most commonly used in our construction projects and is receiving significant attention!

What is the Roof Overlay (Cover Method)?
The roof overlay (cover method) involves leaving the current roof almost as it is and placing a new roof on top of 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 “layered roofing.”
Benefits 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 the biggest feature and leads to various benefits.
The only part that requires demolition and waste disposal is the ridge cap, so compared to complete roof replacement, the costs are 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).
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 with 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 results in lower overall costs.
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 engaged in roof overlay projects without interruption.
