Hello!
I am Yamanaka from Kakeru Koumuten Co., Ltd., a specialist in roofing, exterior wall painting, and exterior renovations located in Aoba-ku, Yokohama, Kanagawa Prefecture!
This is a case study of exterior wall painting, roof painting, roof overlay (Ridgeway), and Kirioke sheet metal work in Yokosuka City, Kanagawa Prefecture!
Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.
Exterior Wall Painting Work Procedure
1. High-Pressure Washing, Surface Preparation, and Ivy Removal
We thoroughly remove moss and dirt from the exterior walls using high-pressure washing.
Ivy is removed by scraping, and any remaining ivy is burned off with a gas burner.


2. Protection of Surrounding Areas
We protect areas that should not be painted, 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 Nippon Paint’s Hypone Fine Deco (rust prevention).
By applying the primer thoroughly, we can achieve better durability and finish.


4. Intermediate Coating
We used Kansai Paint’s Sera M Retan for the paint.
The durability is said to be about 6 to 8 years.
The durability may vary depending on sunlight exposure and other factors.

5. Final Coating
This is the finishing of the exterior wall painting.


6. Painting of Auxiliary Parts (Rain Gutter, Eaves, Mortar)
We thoroughly paint everything that can be painted.
Mortar parts (Nippon Paint/Fine Urethane)
Rain gutter (Nippon Paint/Fine Urethane)
Eaves (Nippon Paint/Ken Ace G-Ⅱ)


7. Cleaning
Roof Painting Work Procedure
1. Surface Preparation
We thoroughly remove moss and dirt from the roof.
2. Protection of Each Part
We protect areas that will not be painted, such as rain gutters, using masking tape and polymer sheeting.
This is an important task.
3. Primer Coat
This time, we used Nippon Paint’s Hypone Fine Deco (rust prevention).
By applying a solid primer coat, we can achieve better durability and finish.

4. Intermediate Coat
We used Nippon Paint’s Fine Perfect Best for the paint.
The durability is said to be about 10 to 12 years.
The durability may vary depending on sunlight exposure and other factors.


5. Top Coating
This is the finishing touch for the roof painting.
Roof Overlay Construction Steps
1. Existing Roof Ridge Demolition
2. Roofing Installation (Waterproof Sheet)
3. Component Processing (Curly Patterns and Eaves)
4. Main Body Construction
5. Ridge Flashing and Wall Rain Stop Flashing Processing
The roofing material used is Ridgeway from Asahi Fiberglass.
Ridgeway comes with a 10-year manufacturer warranty.
Since it uses natural stone that is baked onto the surface, it is a roofing material that does not require painting, which helps reduce maintenance costs!
Additionally, because it uses fine natural stones on the surface, you won’t be troubled by rain noise.
Moreover, it is a lightweight roofing material, making it strong against earthquakes and providing seismic resistance.
You can choose from five colors: Dual Black, Dual Brown, Harvard Slate, Vintage Green, and Earthstone Cedar.
Colors
■Dual Black

■Harvard Slate

■Vintage Green

■Dual Brown

■Earthtone Cedar
Step-by-Step Procedure for Kiryoke Sheet Metal Work
1. Installing the Sheathing
2. Installing the Roofing (Waterproof Sheet)
3. Fabricating the Flashings
4. Fabricating the Flat Sheet Metal
5. Caulking Treatment
That’s all!
Before construction, there was a lot of ivy on the exterior walls, and it was quite a struggle to remove it. Cry
I managed to remove it using a gas burner and scraping.
We received a comment from a customer regarding the ivy debris left in their garden.
We sincerely apologize for the inconvenience caused.
We will take this valuable feedback to heart and strive to improve our efforts moving forward.
