Roof Replacement Construction Procedure
1. Dismantling Existing Roofing Material
2. New Sheathing Installation
3. Roofing Installation (Waterproof Sheet)

We will securely attach this to prevent it from being blown away by the wind. Since there are various durability years and characteristics for roofing sheets, it is important to choose a roofing sheet that matches the durability of the new roofing materials and the roof slope!
4. Accessory Processing (Karakusa and Keraba)
5. Main Construction (Aiji Industry / Super Galtect)
After processing the
Once we have installed up to the ridge, we will set up the necessary materials to secure the ridge board known as the “kanban.” Our company offers three types of kanban: cedar, resin, and galvalume steel, and this time we used galvalume steel!
Galvalume steel is expected to have three times the durability compared to cedar! Unlike resin and cedar, it does not crack, providing peace of mind!
Our original integrated waste board made of galvalume steel for the ridge base is highly durable, has strong fixing power, and excellent wind resistance!
Even if rainwater penetrates from the ridge into the interior, it has a mechanism to discharge rainwater to the outside, ensuring high waterproof performance!
It is ideal for the super Galttect ridge base!
6. Ridge Metal Processing and Sealing at Various Locations
We will process and install the
For the wall edges, we will process and install a component called rain stop metal.
The nails and screws used for fixing are made of rust-resistant stainless steel!
Pack screws, unlike nails, are less likely to pull out and
securely fix the ridge metal to the kanban!
Although it is not visible after construction,
installing a face plate on the inside of the ridge metal
enhances waterproofing!
It firmly protects the ridge, which is a critical point of the roof.
7. Cleaning
We will clean up any debris that has fallen onto the balcony and rain gutters. We conduct this thoroughly as items like nails and metal scraps can lead to injuries. Additionally, we will wipe away any footprints left on the roof to ensure it is clean. [/chat]

About Roofing Materials

The roofing material used is Ai-G Co., Ltd. / Super Galtect. Super Galtect comes with a 15-year paint warranty and a 25-year hole warranty from the manufacturer, along with a 10-year construction warranty from our company! Additionally, it is made of SGL steel, which is resistant to rust.
The insulation material is tightly applied from edge to edge of the roofing material, creating a metal sheet 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 a warm winter.
Moreover, it has soundproofing properties, which reduce the sound of rain. Being lighter than other roofing materials also minimizes the sway during earthquakes, providing earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and our company has the most projects using Ai-G Co., Ltd.’s Super Galtect, making it highly regarded!
