Improper Roof Drainage and Structural Damage:
Improper drainage from your roof can cause catastrophic roof failure and/or damage to your building's structure. A gallon of water weighs over 8 pounds, and if your roof is not displacing a majority of the water from a rainstorm, your roof can very quickly become an enormous burden on the structure of your building.
Proper, Positive Drainage:
Low-Slope roofing is designed to have a positive drainage in one or more directions so that water has the ability to leave the roof. Water may drain directly to a gutter system, or if your building has parapet walls, through a system of scupper drains prior to draining into gutters. Should any of these items become clogged by leaves, debris or ice, the resulting trapped water can tear the roof membrane or worse.
An Inspection is Needed:
Every building with a low-slope roof should be inspected for proper roof drainage regularly. We are happy to take a look at your roof system to ensure that as your building has aged, it has not shifted to a point that water no longer drains properly. Also, you need to be certain that your gutter system is capable of displacing the water from your roof by regularly cleaning downspouts and gutters. Call us today to schedule an inspection and we will check the entire system for you and devise a plan before it is too late.
Ponding water on a low-slope roof can lead to premature degradation of the roofing material, and structural damage from the weight of the water standing on the roof. A ponding water situation should be addressed as soon as it is discovered because a leak is most likely to occur exactly where the water is ponding.
What Causes Ponding Water?
While your low-slope roof was likely designed with a slight pitch to drain water, over time the building settles and lessens the effectiveness of the slope.
Why Does My Roof Leak Long After The Rain Ends?
When it rains, a ponding area on your roof will fill with water. When the rain stops the pond either evaporates or drips into the building after a leak develops. The water that has accumulated on the roof will continue to drip into your building until is is gone or the penetration is above the water line. Ponding areas will develop leaks, and those leaks are very much like a funnel pointed directly at the interior of your structure.
How do We Remedy a Ponding Situation?
Every roof is completely different and we will need to see yours in order to devise a plan to keep it from leaking and remedy the ponding situation. Don't hesitate to call us today for a free inspection.
