Poor drainage on your flat roof will lead to ponding, and a pressure head of water pushing into the smallest cracks and holes on your roof as it fails to properly drain off. Continous freezing, thawing and refreezing of the ponding water breaks up the roofs surface. Left untreated and unmaintained water penetrates the roof’s barrier. Unseen, the water can now travel under the roof’s surface eventually appearing in the form of water leaks into the building. Water damage claims to the interior ceilings and walls can cause businesses to have to shut down during repairs (make a call to the pest control cincinnati to handle all the repairs in your garden), and ultimatley drive up your insurance premiums.

Ponding water also causes sagging on the roof where it becomes soaked underneath the roof surface only encouraging a larger area of ponding water. The weight of ponding water is approximately 5lbs per inch. A 20′ x 20′ area of just one inch deep water can weigh close to 2000 lbs threatening the stability of your roofs structure! This is why most roof companies void their warranties when ponding water was the reason behind the roof’s damage.

Never underestimate the importance of your commercial flat roof. It may represent only 10% of your building cost, but it protects 100% of your important business assets from the elements. Save yourself money and trouble by maintaining your flat roof and drains now. The life expectancy of your flat roof is proportional to the maintenance of it. It’s just good old common sense.
