Ponding On Roof Membrane

Additionally vegetation and other debris may clog drains and cause additional ponding.

Ponding on roof membrane.

Failing to address ponding water also known as standing water can result in water seeping through your roof. Ponding water might not be an immediate threat but if it is allowed to persist over time that water can begin to wear on the roofing membrane. When ponding water on a flat roof starts to develop it is time to start. Over time however ponding water can lead to accelerated aging of the roof membrane.

This will lead to severe water damage and costly bills. This entails stopping ponding water which is a common issue with flat roofs. Ponding water can exacerbate problems for all roofing systems. Correct drainage is the most critical factor in preserving the life of your pvc roof.

Left unresolved ponding water leads to accelerated erosion and deterioration of the membrane surface and results in premature failure of the roof system. Ponding water accelerates roof system aging by. This leads to a decline in the membrane s lifespan and can lead to things like leaks which can cause serious problems for the rest of the building. Ponding water may lead to accelerated erosion and deterioration of the membrane surface that can result in failure of the roof system.

Damage to the roof membrane may occur from chemical and physical attack from the bio growth as well as the expansion and contraction of the bio growth during wet and dry cycles. Allowing even relatively small amounts of moisture beneath the roof membrane may reduce the thermal efficiency of the insulation. Flat roofs by definition are not going to drain as well as slanted roofs. Allowing even relatively small amounts of moisture beneath the roof membrane may reduce the thermal efficiency of the insulation.

However this does not mean you should allow water to accumulate or puddle on top of your roof. A small cut or puncture in a roofing membrane may cause minor damage on a well drained roof surface but the same puncture located in an area of standing water may allow significant water infiltration causing damage to the roof insulation roof deck and building contents.
