Tajima Rooﬁng Inc. was established in 1919, by Takenaga Tajima, for the manufacture and sales ofasphalt waterprooﬁng materials for construction, in Mikawashima, Tokyo. After announcing a patent(patent acquired the following year) for Gilsoid Rooﬁng in 1925, we made it our mission to protect buildings
from rain leakage, and have continued to provide waterprooﬁng materials for a long period of time.
Adding to the asphalt waterprooﬁng material,responding to market demands for vinyl chloride sheet
