Ponding On Roof Membrane

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.

Ponding on roof membrane.

Additionally vegetation and other debris may clog drains and cause additional ponding. Allowing even relatively small amounts of moisture beneath the roof membrane may reduce the thermal efficiency of the insulation. 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. 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.

This entails stopping ponding water which is a common issue with flat roofs. Ponding water can exacerbate problems for all roofing systems. Over time however ponding water can lead to accelerated aging of the roof membrane. Left unresolved ponding water leads to accelerated erosion and deterioration of the membrane surface and results in premature failure of the roof system.

Failing to address ponding water also known as standing water can result in water seeping through your roof. Ponding water isn t an immediate threat in fact roof membranes are made with the same material as pond liners so water penetration is unlikely. Ponding water may lead to accelerated erosion and deterioration of the membrane surface that can result in failure of the roof system. When ponding water on a flat roof starts to develop it is time to start.

Ponding water accelerates roof system aging by. Ponding water is defined as an excessive accumulation of water typically in a low lying area that remains on a roof for 48 hours or longer even when conditions are suitable for drying. However this does not mean you should allow water to accumulate or puddle on top of your roof. Allowing even relatively small amounts of moisture beneath the roof membrane may reduce the thermal efficiency of the insulation.

This will lead to severe water damage and costly bills. Ponding water may lead to accelerated erosion and deterioration of the membrane surface that can result in failure of the roof system.
