According to experts, it’s best to sweep ash off a roof, because “the addition of water will turn the ash into mud which can set like concrete.
It is also advised that using large amounts of water to clean ash off roofs may cause the ash to form a “glue-like ‘cake’ material,” which will be difficult to remove and add more weight to the roof.
But it's a different case in Biñan City where they turn the ash into brick.
“Kaya kailangan nating isako ang mga ito at hindi makabara sa ating mga canal,” Biñan City Mayor Arman Dimaguila said.
