Roof Overlay Construction Procedure
1. Demolition of Existing Ridge and Snow Stops
Skylight Demolition
Skylight Plywood Installation
2. Installation of Roofing (Waterproof Sheet)
It is made of modified asphalt roofing, which is said to have double the durability of regular asphalt roofing.
With a solid roofing layer serving as the primary waterproofing, there will be no leaks!
We will securely attach 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 Industry/Super Galtect)

Once it is laid up to the ridge, we will install the necessary materials for fixing the ridge board, known as the kanban. 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 of the cedar type!

The nails and screws used for fixing are made of stainless steel, which is resistant to rust!

About Roofing Materials
The roofing material used is the Super Galtect from Aijii Industrial.
The Super Galtect comes with a 15-year paint warranty and a 25-year hole warranty from the manufacturer.
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 steel 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.
Additionally, it is lighter compared to other roofing materials, which reduces the sway during earthquakes, making it a good earthquake countermeasure.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and our company has the most installations of Aijii Industrial’s Super Galtect, making it highly regarded!
