Hello!
This is Yamanaka from Kakeru Koumuten Co., Ltd., a specialist in roofing, exterior painting, and exterior renovations located in Aoba-ku, Yokohama, Kanagawa Prefecture!
This is a case study of a roof painting project in Isohama-ku, Yokohama, Kanagawa Prefecture!
Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.
Roof Painting Work Procedure
1. High Pressure Washing
We thoroughly remove moss and dirt with high-pressure washing of the roof.

2. Protection of Various Parts
We protect areas that will not be painted, such as rain gutters, using masking tape and poly masks.
This is an important task.
3. Surface Preparation and Crack Repair
We repair any cracks.
4. Primer Application
This time, we used Nippon Paint’s Best Sealer.
Applying a solid primer makes a difference in durability and finish.

5. Installation of Spacer
After the primer, we insert spacers between the roofing materials to ensure a path for rainwater and moisture to escape.

6. Rust Prevention
We apply rust prevention paint to the ridge cap and snow guards.

7. Intermediate Coating
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 and other factors.

8. Top Coating
This is the finishing touch for the roof painting.

9. Cleaning
This time, we installed a roof scaffold due to the steep roof slope.
During the dismantling of the scaffold, we ensured that even the unpainted areas were thoroughly painted using the jacks of the roof scaffold!

That’s all!
Painting colonial roofs does not extend their durability or lifespan!
While we often hear about measures against leaks, painting colonial roofs only enhances their appearance. If you use heat-reflective paint, it can also improve insulation properties.
For colonial roofs that have exceeded their durability, we recommend the roof overlay (cover method).
