Exterior Painting Construction Steps
1. High-Pressure Washing
We thoroughly remove moss and dirt with high-pressure washing of the exterior walls.


2. Protection of Various Parts
We protect areas that should not be wet, such as windows, sashes, and floors, using masking tape, blue sheets, and polymer masks.
This is an important task.

3. Primer Application
This time, we used SK Kaken’s water-based Soft Surf SG.
By applying a solid primer, we can achieve better durability and finish.

4. Intermediate Coating
We used SK Kaken’s water-based Cerami Silicon for the paint.
The durability is said to be about 10 to 12 years.
The durability may vary depending on sunlight and other factors.
5. Top Coating
This is the finishing touch for the exterior wall painting.

6. Painting of Additional Parts (Rain Gutter, Eaves, Fascia)
We thoroughly paint all items that can be painted.
Fascia (Nippon Paint/Fine Urethane)
Rain Gutter (Nippon Paint/Fine Urethane)
Eaves (Nippon Paint/Ken Ace G-Ⅱ)

7. Balcony Waterproof Coating
We apply a primer, intermediate coat, and top coat that matches the existing waterproofing.
Before Construction

After Construction

8. Replacement of Cap Flashing Caulking


9. Cleaning
Roof Overlay Construction Procedure
1. Dismantling Existing Ridge and Snow Guards
We will dismantle only the ridge flashing and snow guards that obstruct the overlay work.


2. Laying Roofing (Waterproof Sheet)
The roofing used this time is modified asphalt. It is expected to have double the durability of standard asphalt roofing!

3. Fabrication of Accessories (Curly Patterns, Eaves, Waste Boards)
We will process and install the eaves, arabesque, and waste boards.
4. Main Construction
Once the main body is roofed, we will install the purlins at the ridge and wall edges. This time, we used cedar purlins, but there are also purlins made of resin that are resistant to corrosion.
5. Ridge Metal and Rain Stopper Metal Processing
We will process and install the ridge metal. We will firmly apply sealing on the inside of the joints. At the wall edges, we will process and install a component called rain stopper metal. We will also apply sealing firmly.




6. Cleaning
We will remove footprints and debris that have inevitably fallen around the house and inside the rain gutters, and we will wipe clean the area.
We strive to ensure that the area is cleaner after the construction than it was before!

With that, all construction is complete!
About the Roofing Material
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.
Our company also provides a 10-year construction warranty!
Made of Galvalume steel, it is resistant to rust.
Insulation material is tightly applied from edge to edge of the roofing material, creating a metal sheet 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 a warm winter.
Additionally, it has soundproofing properties, reducing the sound of rain.
Moreover, it is lightweight compared to other roofing materials, which reduces the sway during earthquakes, providing earthquake resistance.
You can choose from five colors: Shade Black, Shade Brown, Shade Blue, Shade Moss Green, and Shade Charcoal.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and among our construction achievements, the Super Galtect from Aijii Industry is the most popular and highly regarded!
This time, the cover work in shade blue turned out very well!
Thank you for your request!!

I was very happy to receive a complimentary message from our customer!
What is the Roof Overlay (Cover Method)?
The roof overlay method involves leaving the current roof almost as it is and placing a new roof on top of it.
Literally, it is a method of covering a roof with another roof. Therefore, the roof becomes double-layered. Since the roof is laid over, it is also referred to as “overlapping roofing.”
Advantages of the Overlay Method
Since a “new roof” is placed over the “current roof,” demolition work is almost unnecessary, meaning that very little waste is generated.
This is its biggest feature, leading to various advantages.
The only part that requires demolition and waste disposal is the ridge cap, so compared to complete roof replacement, the cost is lower.
In 2004, regulations regarding the concentration of asbestos in raw materials were changed (for details, please refer to the Ministry of Health, Labour and Welfare website).
Some building materials used in constructions completed before 2004 contain asbestos. Asbestos-containing materials are difficult to demolish due to their high environmental impact, and the costs for demolition and waste disposal are also high. The overlay method, which generates almost no waste, is ideal for such roofs.
You may be wondering, “Is it safe to live in a building that uses asbestos-containing materials?” but rest assured. As long as there is no destruction or crushing, it will not disperse into the air.
If you are unsure about the type of roof on your home, please feel free to consult us.
Additionally, the construction can be completed in a shorter period than painting or complete roof replacement. A shorter construction period means lower labor costs, which in turn makes the expenses lower.
The psychological anxiety of having to live in an unusual environment is also reduced.
When scaffolding is set up, there may be inconveniences such as difficulty entering and exiting or not being able to open windows. Being able to return to normal life in a short period is a significant advantage.
Our company specializes in roofing work, but the roof overlay method is the most frequently performed type of work we do. We are very grateful that we are continuously able to carry out roof overlay method projects without interruption.
