Roof Overlay Construction Procedure
1. Existing Roof Ridge Flashing

2. Installing Roofing (Waterproof Sheet)

It is made of a delayed adhesive 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 solid, there will be no leaks!
We will securely adhere it to prevent it from blowing away.
3.Accessory Processing (Karakusa, Keraba, Valley)


The accessories used are genuine Galtect accessories made of SGL copper plate!
4.Main Construction (Aiji Industrial/Super Galtect)


Once the roofing is completed up to the ridge, we will install a necessary material called a “kanban” to secure the ridge flashing. The kanban can be made of cedar or resin, and this time we used a resin type!
The resin type is expected to have twice the durability compared to the cedar type!
5.Ridge Flashing Processing & Sealing at Various Locations


We use stainless steel nails and screws that are resistant to rust!
6. Cleaning

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 plates, it is also 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.
When installed, insulation is applied even to the parts where the roofing materials overlap, and the surface is coated with high heat-reflective paint, allowing for a cool summer and warm winter experience.
Additionally, it has soundproofing properties, reducing the sound of rain.
Being lighter than other roofing materials, it also minimizes 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 projects and is receiving significant attention!
