Tama-ku | Y Residence | We performed a roof overlay (cover method) with a skylight (top light)!

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 Tama-ku, Kawasaki City.
There are several types of exterior renovations, and this project involves the roof overlay (cover method) using Super Galtect!
We implemented measures against leaks through the roofing work!

The existing roofing material is slate containing asbestos.
Since there was a skylight, we also performed metal work for the skylight as part of the roof overlay method!

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

Roof Overlay Construction Procedure

1. Existing Roof Ridge Cap

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

2. Roofing Installation (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.
If the roofing is solid, it will prevent leaks as it serves the role of primary waterproofing!

3.Accessory Processing (Karakusa & Keraba)


Before the main roof installation, we will process accessories such as keraba and karakusa!
Since the area around the skylight is prone to leaks, we will raise the roofing and apply waterproof tape before proceeding with the metalwork!
The accessories used are genuine Galtect accessories made of SGL copper plate!

4.Main Construction (Aiji Industrial/Super Galtect)


After processing the accessories, we will install the Galtect main body up to the ridge!
Once the installation reaches the ridge, we will set up a nailing board, which is necessary for securing the ridge metal. There are types of nailing boards made of cedar and resin, and this time we used cedar!

5.Ridge Metal Processing & Sealing at Various Locations


Next, we will process and install the ridge metal. We will thoroughly apply sealing on the inside of the joints. For the wall edges, we will process and install a rain stop metal.
The nails and screws used for fixing are made of stainless steel, which is resistant to rust!

6.Cleaning


We will clean up any debris that has fallen onto the balcony or rain gutter. We will thoroughly remove items such as nails and metal scraps that could cause injuries. Additionally, we will wipe away any footprints left on the roof to ensure it looks clean.

About Roofing Materials

The roofing material used is the Super Galtect from Aijii Industrial.
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, it is resistant to rust.
Insulation material is tightly applied from edge to edge of the roofing material, creating a metal sheet that integrates steel and insulation.
During installation, 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 a warm winter.
It also has soundproofing properties, reducing the sound of rain.
Moreover, it is lightweight compared to other roofing materials, which minimizes the sway during earthquakes, providing earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and our company’s track record shows that the Super Galtect from Aijii Industrial is the most frequently used, gaining significant attention!
