After about three years of life on our vetiver thatch roof we recently replaced the thatch with micro-concrete roofing tiles (MCR). MCR tiles and metal roofing are fast and easy to install, and both work well for roofwater harvesting. I like MCR tiles because they’re more durable and look better than most metal roofing, and don’t get as noisy in rainstorms. We cut the tiles with a right angle grinder and then covered the joints with cement. This roof should last 25 years or more. Also note, the vents on top will provide even better ventilation. (They’re screened to keep birds out.)

Vaulted Roof Technique
“The vaulted roofing system using conical tile has been developed and used by Centre of Science for Villages, Wardha, Maharashtra for the last four decades. The roof is easy to construct and uses local materials and skills.”
