Hello! This is Kakeru Koumuten Co., Ltd.!
Many of you might be considering a roof renovation soon, but wondering which roof color to choose… Once you replace or repaint it, you’ll be living with the same color for years, so you don’t want to regret your choice!
Therefore, for those considering roof painting renovations and re-roofing work around Aoba-ku, Yokohama, we would like to introduce popular roof colors that have many construction examples in Aoba-ku.
If you’re struggling with choosing a roof color, please use this as a reference!
Here it is! The popular roof color in Aoba-ku!
The most frequently constructed color by our company, which is also popular in Aoba-ku, is definitely “Black系”. It matches well with exterior walls and is less prone to showing dirt, which might be the reason for its popularity.
Among them, our recommended roofing material Super Galtect in the color Shade Black is the number one choice! Super Galtect is known for its durability, insulation, and wind resistance, and its lightweight and shatterproof nature also contributes to its safety and popularity.
What is our recommended roofing material “Super Galtect”?
Super Galtect is a roofing material that is thoroughly insulated from edge to edge, made of metal sheets that integrate steel plates and insulation materials, and is made of SGL steel plates, which are also resistant to rust.
Excellent in finish, durability, thermal insulation, soundproofing, and wind resistance, our company’s construction achievements show that the Super Galtect from Aijii Industry is the most popular and has garnered significant attention!
When installed, insulation material is applied even to the parts where the roofing materials overlap, and the surface is coated with a highly heat-reflective paint, allowing for a cool summer and a warm winter. Additionally, it has soundproofing properties, reducing the sound of rain. Furthermore, it is lightweight compared to other roofing materials, which minimizes shaking during earthquakes, providing earthquake resistance.
The Super Galtect comes with a manufacturer warranty of 15 years for the coating and 25 years for perforation.
Additionally, we provide a 10-year construction warranty!
Available in a total of 6 colors!
■ Shade Black

■ Shade Brown

■ Shade Blue

■ Shade Moss Green

■New Color Shade Wine Red

The actual color may differ slightly. Please confirm again with the color samples we will bring when we visit for the estimate.

Roofing Work (Roof Repair) Schedule
Depending on the type of roofing material and the local climate, generally, roofing work (roof repair) is done every 10 to 15 years. After that, it is advisable to inspect every 5 years and carry out repairs or painting as needed. Regular maintenance can help detect small deterioration or damage early, reducing the risk of large-scale construction or repairs.
However, this is just a guideline, and it can vary depending on the material of the roof and environmental conditions such as high humidity, strong winds, and snowfall. Under severe weather conditions, more frequent checks may be necessary. Additionally, roofing work (roof repair) involves working at heights, so it is advisable to hire a professional contractor.
Cost Estimates for Roofing Work (Roof Repair)
The cost of roofing work (roof repair) varies greatly depending on the content and scale of the work, as well as the materials used, but having a general understanding of the cost range can help with budgeting.
For example, in the case of a typical roof replacement, the average cost is 30,000 to 50,000 yen per tsubo. This includes material costs, construction fees, and miscellaneous expenses. For small repairs, it may be several tens of thousands of yen, for large repairs or partial replacements, it may be several hundred thousand yen, and for a complete roof replacement, it often amounts to several million yen.
This is a rough estimate, and for specific costs, please feel free to contact Kakeru Koumuten.
What are the Points for Choosing Colors Without Making Mistakes?
The color of roofing materials affects the sunlight reflectivity, with colors closer to white having a higher reflectivity, thus enhancing heat insulation.
For example, with Super Galtect, the “Shade Charcoal” is the color with the highest heat insulation.
If heat insulation is a priority, it is recommended to choose a color close to white.
However, white can be difficult to match with the exterior wall color and tends to show dirt more easily.
Additionally, many manufacturers do not produce white colors for either paints or roofing materials.
In contrast, black is easy to match with any color of the building and has the advantage of being less prone to showing dirt.
Our company can also create simulations by photographing your building.
