Two Possible Treatment Options For Ponding Water Issues

by Howard Barnett

While flat roofs can be aesthetically pleasing and are typically cheaper to install than sloped roofs, they are more prone to ponding water issues. This is when water from rain or other sources settle into small pools rather than draining away to the ground, which can occur for a variety of reasons including poor roof pitch and clogged drains. Over time, ponding water can cause leaks and structural issues. If you roof tends to pond water, here are two possible treatment options. 

Apply a Waterproof Roof Coating

One way to minimize the damage ponding water may cause is to apply a waterproof roof coating. Just as it sounds, one or two layers of a suitable roof coating can prevent standing water from degrading and penetrating through roofing materials. It can also help resolve existing leaks caused by previous damage, reduce energy bills by reflecting heat from the sun, and extend the life of your roof by about 25 years.

However, it's critical you choose a roof coating that is rated for ponding. Typically this type of coating is made from silicone or polyurethane. Coatings not rated for ponding will deteriorate prematurely after being subjected to long periods of time underwater and may even make the situation worse by trapping water between the coating and the roofing materials. Contact a local outlet, such as Stetson Painting, for further assistance.

Make Changes to the Roof

Although roof coatings can considerably reduce the effect standing water has on your roof, it's still only a temporary fix. A more permanent way to correct ponding problems is to have a roofing contractor install drains or crickets in areas where standing water collects to facilitate drainage. Depending on where the ponding occurs, this may require altering the building's interior structures as well (e.g. place piping through the attic).

Another permanent option is to repitch the roof so water automatically rolls off it. This typically involves making extensive changes to the roof and frame of the home, depending on how high the pitch will be. While you can alter the pitch yourself, this is not recommended unless you have some skill and experience in this area. It's best to have a professional roofer perform this type of repair for you.

Ponding water can be a challenging issue to address. However, there is a variety of solutions you can employ to mitigate the problem. For more information about ponding treatment options or to have a waterproof coating applied to your roof, contact a roofing contractor for assistance.
