Construction Data for Aoba-ku, Yokohama

Roof Overlay Construction Procedure

1. Demolition of Existing Ridge and Snow Stops

We will dismantle unnecessary parts (ridge flashing) 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 flashing coming loose or being blown away.

2. Laying of Roofing (Waterproof Sheet)

Next, we will apply the waterproof sheet! The roofing material used is Jouyu Pulp Industry/Sunlight G!
It is made of modified asphalt roofing, 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 make sure to apply it securely so it doesn’t blow away.

3.Accessory Processing (Karakusa and Keraba)

Before the main roof construction, 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 body up to the ridge!
Once it is installed up to the ridge, we will place the necessary materials called “kanban” to secure the ridge flashing. We offer three types of kanban: cedar, resin, and galvalume steel, and this time we used the cedar type!

5.Ridge Flashing Processing and Sealing

Next, we will process and install the ridge flashing. We will thoroughly apply sealing on the inside of the joints.
The nails and screws used for securing are made of stainless steel, which is resistant to rust!

6.Cleaning

We will clean up any debris that has fallen onto the balcony and other areas. We will thoroughly remove nails and metal scraps to prevent 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 Industry.
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.
The insulation material is tightly applied from edge to edge of the roofing material, creating a metal plate that integrates the steel plate and insulation.
During installation, 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, making it a good earthquake countermeasure.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aijii Industry is the most frequently used in our construction achievements and is receiving considerable attention!
