Nakahara-ku, Kawasaki City | M’s Residence | Performed roof overlay work from Pamir to Super Galtect!

Hello!
I am Yamanaka from 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 Nakahara-ku, Kawasaki, requested by Company S.
There are several types of exterior renovations, and this project involves a roof overlay (cover method) using Galtect!
We implemented measures against leaks due to roofing work!

The existing roofing material is Nichiha/Pamir! Nichiha/Pamir is well-known as a roof that cannot be painted! An effective renovation method is the cover method before the underlying material deteriorates!

On this page, we 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 Construction Procedure

1. Dismantling Existing Roof Ridge Flashing

We will dismantle the existing roofing materials (ridge flashing, snow guards) that are unnecessary for the

roof 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 flashing coming loose or being blown away.

2. Installing Roofing (Waterproof Sheet)

3. Fabricating Accessories (Kera and Karakusa)

4. Main Construction (Aiji Industry/Super Galtect)

After processing the

5. Processing of Ridge Cap and Sealing at Various Locations

Next, we will process and install the ridge cap. We will thoroughly apply sealing on the inside of the joints. For the wall edges, we will process and install a component called the rain guard. We will use a primer before applying the sealing at the wall edges.
We will use stainless steel nails and screws that are resistant to rust for fixing![/chat]

6. Cleaning

We will clean up any debris that has fallen onto the balcony or rain gutter. 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.[/chat]

About Roofing Materials

The roofing material used is the Super Galtect from Aji Industrial Co., Ltd.
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 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.
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.
Additionally, it has soundproofing properties, which reduce the sound of rain.
Being lighter than other roofing materials, it also minimizes the sway during earthquakes, contributing to earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aji Industrial Co., Ltd. is the most frequently used in our construction achievements and is receiving considerable attention!

What is the Roof Overlay (Cover Method)?

The roof overlay method involves leaving the current roof almost intact and placing a new roof on top of it, effectively covering it.
Literally, it is a method of covering a roof with another roof. Therefore, the roof becomes double-layered. Since the roof is laid over another, it is also referred to as “overlapping roofing.”

Advantages of the Overlay Method

Since a “new roof” is placed over the “current roof,” there is almost no need for demolition work, meaning very little waste is generated.
This is its most significant feature, leading to various advantages.

The only part that requires demolition and waste disposal is the ridge cap, making it more cost-effective compared to complete roof replacement.
In 2004, regulations regarding the concentration of asbestos in raw materials were changed (for details, please refer to the Ministry of Health, Labour and Welfare’s website).
Some building materials used in structures built before 2004 contain asbestos. Asbestos-containing materials are challenging to demolish due to their high environmental impact, resulting in high costs for both demolition and waste disposal. The overlay method, which generates almost no waste, is ideal for such roofs.

Some may wonder if it is safe to live in buildings that use 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 us.

Additionally, the construction can be completed in a shorter timeframe compared to painting or complete replacement. A shorter construction period means lower labor costs, which in turn makes the overall cost cheaper.
The psychological anxiety of having to live in an unusual environment is also reduced.
When scaffolding is set up, it can be inconvenient to enter and exit, and windows may be difficult to open. 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 continuously have projects for the roof overlay method without interruption.
