A roof that is strong against typhoons and earthquakes. Spray to create a seamless roof surface. Ideal for the renovation of slate roofs. Achieved 1 million square meters nationwide.

The "SOSEI Method" is a unique method developed by Toyoko that allows for waterproofing, reinforcement, and insulation to be performed in a single application, making it suitable for the renovation of slate roofs. By spraying three layers of special resin to seamlessly integrate the surface, it prevents gaps and cracks by blocking drafts from entering the slate joints and edges. Additionally, with a roof load of 2.3 to 2.5 kg/m2, it is lighter compared to steel plate covering methods, which reduces the burden on the building structure and lowers reinforcement costs during seismic work. 【Features】 ■ Integrates the overlaps of slate, hook bolts, and ventilation joints ■ Contributes to reducing the risk of roof and ceiling materials falling inside the building ■ Improves insulation, helping to suppress the rise in attic room temperature even on extremely hot days ■ Proven track record of 1 million m2 nationwide, including major manufacturers ■ Reliable leak compensation for up to 10 years (for slate roofs) *You can view documents that include test data by downloading the PDF. Please feel free to contact us with any inquiries.

basic information

【Other Features】 ■ Construction can be completed in a short period without stopping operations, as it is performed only from the roof surface. ■ There is no need for high-pressure washing before construction, and the resin covering the surface can prevent the scattering of asbestos. ■ It has been confirmed that there is no damage even after 50 drops of a 1kg steel ball, contributing to puncture prevention. *For more details, please refer to the materials. Feel free to contact us as well.

"In order to protect the quality of the manufacturing line and products, we want to extend the life of the aging factory roof without stopping the production line." The SOSEI business was born from such customer feedback. By combining paint technology and resin technology, our unique three-layer spraying restoration method particularly encapsulates aging slate roofs that contain asbestos and cannot be washed, providing effects such as "waterproofing," "insulation," "reinforcement," "soundproofing," and "condensation prevention," and has gained support from many customers due to its cost advantages. The SOSEI method operates under a complete construction system, focusing on quality and safety, and offers proposals for roof renovation to protect the production line and products.
