We would like to introduce potential subsidies that can be used for roof renovations such as roof painting!

Hello!
We are Kakeru Koumuten Co., Ltd., a specialist in roofing, exterior wall painting, and exterior renovations located in Aoba-ku, Yokohama, Kanagawa Prefecture!
Depending on the region, there is a possibility that you may be eligible for subsidies or grants from local governments or municipalities when renovating your roof.
Generally, construction aimed at energy conservation or earthquake resistance is eligible for subsidies, and there are no subsidies or grants for roof renovations due to aging.
Since it is often difficult to apply for subsidies after the construction is completed,
we recommend checking with your local government to see if there are any applicable subsidies or grants.
While receiving subsidies or grants may seem beneficial, depending on the type, costs for expert assessments or report preparation may actually end up taking more time and money.
If you have any questions, please feel free to contact us.
We will check the information and condition of your building to see if there are any valid subsidies or grants available!
◯Energy Conservation Renovation Subsidies
1) Eligible Roof Renovation Work: Roof Painting

If roof painting is done with heat-reflective paint that has a solar reflectance of 50% or more, depending on the municipality, a subsidy of up to 20% may be granted.
The solar reflectance varies by color, with whiter and closer to silver having higher solar reflectance, while the closer to black the lower the reflectance becomes.
Since this is often indicated in the color samples of the paint catalog, it is necessary to check before proceeding with the work.
Exterior wall painting may also be eligible depending on the municipality.
Additionally, the application methods differ by municipality, such as pre-construction and post-construction applications, so caution is required!

About Earthquake-Resistant Roof Renovations
Under the wooden house earthquake resistance renovation subsidy system, renovation work that achieves a score of 1.0 or higher through seismic diagnosis, such as foundation reinforcement, bracing (shear walls) reinforcement, and roof replacement for weight reduction, is eligible for subsidies if applicable!
The seismic performance of a house is greatly influenced by the weight of the building, so lightening the roof can improve seismic resistance.
For example, galvalume steel sheets and SGL steel sheets are lightweight yet highly durable, helping to mitigate the effects of shaking during an earthquake!
However, not all buildings that use heavy tiles or roofing materials have low seismic performance. Buildings constructed after the 1981 seismic standard revision have sufficient strength incorporated into the structure to support tiled roofs!
Therefore, in buildings built to the new standards, the risk of collapse due to tiled roofs is very low, and for houses built under the old seismic standards, preemptive measures are recommended, so it is important to know whether your house is built to the old or new seismic standards. These circumstances can vary as well.
Thus, in buildings with poor balance between strength and weight due to old seismic standards, roof lightweight renovation can be effective.
However, it is not uncommon for tiled roofs to collapse in areas affected by earthquakes, so checking and maintaining the condition of tiled roofs is important for any house.
At Kakeru Koumuten Co., Ltd., we also handle roof replacements and maintenance of tiled roofs (plaster work), and we have the knowledge and experience for both types of roof renovations, so please feel free to consult with us. However, we recommend considering lightweight renovation through roof replacement work, especially if your tiled roof is quite old!
