Roof Overlay Construction Procedure

1. Demolition of Existing Ridge and Snow Stops

We will dismantle unnecessary parts (ridge flashing) for the overlay method!The lifespan of wooden purlins is about 10 to 15 years. Exceeding the lifespan can lead to corrosion and discoloration, resulting in the ridge flashing coming loose or being blown away.

Skylight Demolition

Skylight Plywood Installation

We will dismantle the skylight and partially dismantle the surrounding roofing materials to fit the plywood!

2. Installation of Roofing (Waterproof Sheet)

The roofing used is Jouyu Pulp Industry/Sunlight G!
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)

Before the main roof construction, we will process and install accessories such as keraba, karakusa, and valley metal!
The accessories used are genuine Galtect accessories made of SGL copper plate!

4. Main Construction (Aiji Industry/Super Galtect)


After processing the accessories, we will lay the Galtect main body up to the ridge!
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!

5. Ridge Board Processing and Sealing at Various Locations


Next, we will process and install the ridge board. We will firmly apply sealing on the inside of the joints. At the wall edge, we will process and install a component called the rain stop metal.
The nails and screws used for fixing are made of stainless steel, which is resistant to rust!

6. Interior Closet Ceiling Replacement

Existing Ceiling Demolition

We will dismantle the ceiling

. You can see that the ceiling is discolored due to water leakage

.

New Ceiling Replacement

After carefully measuring the dimensions

, the ceiling will be replaced, and the work will be complete!

7. Cleaning


We will clean up the debris that has fallen onto the balcony and rain gutters. We will thoroughly remove nails and metal scraps that could cause injuries. Additionally, we will wipe away any footprints left on the roof to ensure it looks clean.

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!
