Preservative treatment were made in seven different roofing materials with Copper-Chrome-Boron (CCB) at different concentration by soaking process. These were paddy straw, wheat straw, jute stick, sungrass, ulu grass, sugercane leaf and Nipa fruticans. It was observed that retention of preservative chemicals varies from species to species at the same concentration. From the service test it was observed that by using low concentrated solution at minimum immersion period, durability of the thatching materials can increased which is economically acceptable and enviromnental pollution is also minimized.
