Why Roof Plumbing Is Important A roof does more than shield your home from rain and sun. An effective drainage system is also needed to channel rainwater away from the property. Without proper roof plumbing, water can pool, leading to leaks and damage to your walls, foundation, and overall structure. A Roof Plumber Coburg is responsible for installing and maintaining vital components of your roof’s drainage system, such as gutters, downpipes, and flashing. Regular roof plumbing maintenance ensures water flows away from your property and prevents issues like mold growth, structural damage, and costly repairs.
