Hello!
We are 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 Higashimurayama City, Tokyo.
The roofing renovation involved a roof overlay (cover method) using Super Galtect and painting of metal parts!
The roof overlay involves dismantling and removing the existing roofing materials and replacing them with new ones to prevent leaks.
This building is an apartment, and we received a request from the owner.
Since there were residents, we conducted the roofing work after providing prior explanations and greetings.
Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.

Roof Replacement Construction Procedure
1. Demolition of Existing Roofing Materials
2. Installation of New Sheathing
3. Installation of Roofing (Waterproof Sheet)
This underlayment boasts the highest quality, unmatched in waterproofing and durability. By sandwiching a modified asphalt layer between non-woven fabric and base paper, it fully demonstrates the inherent performance of modified asphalt.
The expected durability is about 30 years!
4. Fabrication of Accessories (Karakusa, Keraba, Valley Metal)
The materials used for the accessories are SGL steel plates.
5. Main Construction (Aiji Industrial/Super Galtect)
Once the installation reaches the ridge, we will install the necessary materials to secure the ridge board called “kanban.” We offer three types of kanban: cedar, resin, and galvalume steel, and this time we used galvalume steel!
Galvalume steel is expected to have three times the durability compared to cedar! Unlike resin and cedar, it won’t crack, so it’s safe!
Our original integrated waste board made of Galvalume steel for the ridge base is highly durable, has strong fixation, and excellent wind resistance! Even if rainwater seeps in from the ridge, it has a mechanism to discharge rainwater to the outside, ensuring high waterproofing performance! It is perfect for the Super Galtect ridge base!
6. Ridge Cap Processing and Sealing at Various Locations
We will process and install a component called rain stop metal at the wall edge.
The screws used for fixation are made of rust-resistant stainless steel with waterproof packing!
Unlike nails, screws with packing are less likely to come loose and securely fix the ridge cap to the purlin!
Although it is not visible after construction, by installing a face plate on the inside of the ridge cap, waterproofing is enhanced!
It firmly protects the ridge, which is a critical point of the roof.
7. Cleaning
Iron Part Painting Work Procedure
1. Surface Preparation (Keren)
2. Primer (Rust Preventative and Lastraint)
3. Intermediate and Top Coats (Rock Paint / Yumelock)
The paint used is Yumelock!
5. Other Metal Painting (Coping and Steel Frame)
・Coping
・Steel Frame
6. Cleaning
About the Roofing Material
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.
Insulation material is tightly adhered from edge to edge of the roofing material, creating a metal plate that integrates the steel plate and insulation.
During installation, 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.
Being lighter than other roofing materials, it also reduces the sway during earthquakes, making it a good earthquake countermeasure.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aijii Industry is the most commonly used in our construction achievements and is receiving significant attention!
