AFTER

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 Setagaya-ku, Tokyo.
For this roof renovation, we performed a roof overlay (cover method) using Super Galtect!
The roof overlay involves dismantling and removing the existing roofing materials and replacing them with new ones to prevent leaks.

Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.

Roof Overlay Construction Procedure

1. Dismantling Existing Roofing Materials


We will dismantle the existing roofing materials!

2. Installing New Sheathing


After dismantling the existing roofing materials, we will process and install new sheathing to fit the dimensions!

3. Installing Roofing (Waterproof Sheet)

The roofing used is Jouyu Pulp Industry/Sunlight G!
It is made of modified asphalt roofing material, which is said to have double the durability of regular asphalt roofing.
With a primary waterproofing role, if the roofing is solid, there will be no leaks! We will ensure it is securely attached to prevent it from blowing away.

4. Fabrication of Accessories (Karakusa and Keraba)

Before the main roof construction, we will fabricate and install accessories such as keraba and karakusa!
The materials used for the accessories are SGL steel plates.

5. Main Construction (Aiji Industry/Super Galtect)

After the accessory fabrication, we will install the Galtect main roofing up to the ridge! After the accessory fabrication, we will install the Galtect main roofing up to the ridge! We will also perform metal work around the skylight!
Once the roofing is completed up to the ridge, we will install a nailing board, which is necessary for securing the ridge cap. There are types of nailing boards made of cedar and resin, and this time we used a resin type!
The resin type is expected to have twice the durability of the cedar type!

6. Processing of Ridge Cap and Sealing at Various Locations


We will process and install the ridge cap. We will apply sealing thoroughly on the inside of the joints.
At the wall edges, we will fabricate and install a rain guard metal component.
The nails and screws used for securing are made of stainless steel, which is resistant to rust!

7. Cleaning

About Roofing Materials

The roofing material used is Aijii Industry’s Super Galtect.
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 densely applied from edge to edge of the roofing material, creating a metal plate that integrates steel plate and insulation.
During installation, insulation is applied even to the parts where the roofing materials overlap, and the surface is coated with high heat-resistant paint, allowing for a cool summer and warm winter.
Additionally, it has soundproofing properties, reducing the sound of rain.
Being lighter than other roofing materials, it reduces the sway during earthquakes, providing earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and Super Galtect from Aijii Industry is the most frequently used in our construction achievements and is highly regarded!
