How does roof slope affect drainage and outlet placement in the estimate?

Adequate slope toward properly placed drainage outlets is essential for a flat RCC terrace to shed water quickly rather than allowing it to pond, which stresses the waterproofing membrane over time. The calculator's waterproofing allowance assumes a properly sloped and detailed terrace; a poorly sloped roof will likely need more frequent waterproofing repair regardless of […]
