Aoba-ku, Yokohama | S Residence | We performed a roof overlay using Super Galtect!

BEFORE

AFTER

Hello!
We are 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 an exterior renovation project in Aoba-ku, Yokohama.
The work involved a roof overlay (cover method) using Super Galtect!
We implemented measures against leaks through the roofing work!

This time, we received an inquiry about a leak, and we were entrusted with the leak investigation.
After identifying the leak location, the customer expressed a desire to continue living there for a long time, so we proposed a cover project using Super Galtect!

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

Roof Overlay Construction Procedure

1. Existing Roof Ridge Flashing

We will dismantle unnecessary parts (ridge flashing) for the overlay method!The lifespan of wooden purlins is about 10 to 15 years. Exceeding the lifespan can lead to corrosion and discoloration, resulting in the ridge flashing coming loose or being blown away.

2. Installing Roofing (Waterproof Sheet)

The roofing material used is Tajima Roofing / Tadi Self!
It is made of a delayed adhesive modified asphalt roofing material, which is said to have double the durability of regular asphalt roofing.
As a primary waterproofing measure, if the roofing is solid, there will be no leaks!
We will securely adhere it to prevent it from blowing away.

3.Accessory Processing (Karakusa, Keraba, Tani)


Before the main roofing work, we will process and install accessories such as keraba and karakusa!

The accessories used are genuine Galtect accessories made of SGL copper plate!

4. Main Construction (Aiji Industry / Super Galtect)


After processing the accessories, we will install the Galtect main roofing up to the ridge!
Once the roofing is completed up to the ridge, we will install necessary materials called “kanban” to secure the ridge cap. There are types of kanban made from cedar and resin, and this time we used cedar!

5. Ridge Cap Processing and Sealing at Various Locations


Next, we will process and install the ridge cap. We will firmly apply sealing on the inside of the joints. At the wall edges, we will process and install a component called rain guard metal.
We will use stainless steel nails and screws that are resistant to rust!

6. Cleaning


We will clean up any debris that has fallen onto the balcony and rain gutters. We will thoroughly remove items like nails and metal scraps that could cause injuries. Additionally, we will wipe away any footprints left on the roof to keep it clean.

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.
Our company also provides a 10-year construction warranty!

It is made of SGL steel plate, which is also 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 highly 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 lighter 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 our company’s installation record shows that Aijii Industry’s Super Galtect is the most popular and highly regarded!
