Blow-off Roof Renovation Method "SOSEI Method" *Materials with test data provided
SOSEI Method
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 m² nationwide.
The "SOSEI Method" is a unique construction 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. Furthermore, 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 the joints of ventilation openings ■ Contributes to reducing the risk of roof and ceiling materials falling into the building ■ Improves insulation, helping to control 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 containing test data from the "PDF Download."
