Hello!

Here are some examples of exterior renovation work in Saiwai-ku, Kawasaki.
There are several types of exterior renovations, and this time, the work involves the roof overlay (cover method) using Super Galtect!
We have implemented measures against leaks through the roofing work!

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

 

 

Roof Overlay Construction Procedure

1. Dismantling Existing Ridge and Snow Stops

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 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.
As a primary waterproofing measure, if the roofing is properly installed, there will be no leaks!

We will securely attach it to prevent it from blowing away!

3.Accessory Processing (Karakusa and Keraba)


Before the main roofing work, we will process and install accessories such as keraba and karakusa!
The accessories used are the genuine accessories from Galtect, 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 of cedar and resin, and this time we used the resin type!
The resin type is expected to have twice the durability compared to the cedar type!

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 edge, we will process and install a component called a rain guard metal.
The nails and screws used for fixing are made of stainless steel, which is resistant to rust!

6.Cleaning


We will clean up the 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 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.
We also provide 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 the steel plate and insulation.
When installed, 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.
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 the Super Galtect from Aijii Industrial is the most commonly used in our construction projects and is receiving significant attention!
