Temporary scaffolding

Roof overlay (cover method)

Existing substrate / Materials used

Existing roofing material: Slate
Materials used for roof overlay method: Super Galtect (Color: Shade Wine Red)
Durability: Approximately 35 to 40 years, in-house warranty: 10 years, manufacturer warranty: coating 15 years, red rust 20 years, perforation 25 years

Construction Period Approximately 1 week Completion Month October 2022

Roof Overlay Construction Procedure

1. Dismantling Existing Roof Ridge Flashing

We will dismantle unnecessary existing roofing materials (ridge flashing, snow guards) for the

overlay method! The durability of wooden purlins is approximately 10 to 15 years. Exceeding the durability period can lead to corrosion and discoloration, resulting in the detachment or scattering of the ridge flashing.

2. Installing Roofing (Waterproof Sheet)

The roofing used for

is Nisshin Kogyo/Kappa 23!
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 solid, there will be no leaks!
We secure it firmly with steel plate chips to prevent it from blowing away.

3.Accessory Processing (Karakusa, Keraba, Valley)


Before the main roofing work for

, we will process and install accessories such as keraba, karakusa sheet metal, and valleys!

The accessories used are the genuine accessories of Galttect, made of SGL copper plate!

4. Main Construction (Aiji Industrial/Super Galttect)


After processing the accessories for

, we will install the Galttect main roofing up to the ridge!
Once the roofing is completed up to the ridge, we will install the necessary materials to secure the ridge board, known as the kanban. There are types of kanban made of cedar and resin, and this time we used cedar!

5. Ridge Cap Processing & Sealing at Various Locations


Next, we will process and install the ridge cap. We will thoroughly 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 the debris that has fallen onto the balcony and rain gutters. We will thoroughly remove any nails or metal scraps that could cause 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 Industrial.
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 highly heat-resistant paint, allowing for a cool summer and warm winter.
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, providing earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and the Super Galtect from Aijii Industrial is the most frequently used in our construction achievements, gaining significant attention!
