Construction Data for Residence Y in Aoba-ku, Yokohama

Roof Overlay Construction Procedure

1. Demolition of Existing Ridge and Snow Stops

We will dismantle unnecessary parts (ridge flashing) for the cover 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 detachment and scattering of ridge flashing.

2. Installation of Roofing (Waterproof Sheet)

Next, we will install the roofing sheet (waterproof sheet)!

The roofing used is Tajima Roofing/Tadis Self Cover!
This is a self-adhesive roofing sheet specifically for the roof overlay method, suitable for fragile slates like Colonial NEO! Its durability is about 30 years, which is three times that of regular asphalt roofing, making it a highly durable roofing sheet.
As a primary waterproofing measure, if the roofing is properly installed, there will be no leaks!
We will ensure it is firmly attached to prevent it from blowing 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 (Aijii Industry/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 the necessary materials to secure the ridge board, known as the kanban. We offer three types of kanban: cedar, resin, and galvalume steel, and this time we used the galvalume steel version!
The galvalume steel version is expected to have 3times the durability compared to the cedar version! Unlike resin or cedar, it won’t crack, providing peace of mind!

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. For the wall edge, we will process and install a component called a rain guard metal.
We 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 nails and metal scraps to prevent injuries. Additionally, we will wipe off 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 also 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.
It also has soundproofing properties, reducing the sound of rain.
Moreover, it is lightweight compared to other roofing materials, which reduces the sway during earthquakes, providing earthquake resistance.
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 highly regarded!
