What To Do About Standing Water On A Flat Roof
Standing water on a flat roof can be a common problem for many homeowners in San Diego, especially after a severe rainstorm such as the one that hit the area over the last few weeks. This can be caused by poor drainage, blocked gutters, or clogged downspouts. While it might seem like a bad thing, standing water on a flat roof is not necessarily a problem as long as the water is able to evaporate after a rainstorm. In fact, flat roofs are designed to be able to handle small amounts of standing water. However, if the water is not able to evaporate, it can cause a number of issues, including leaks, mold growth, and structural damage.
The first step you need to consider is to figure out whether or not the standing water has the potential to cause a problem for your roof. In order to cause a problem, water needs to remain on the roof in a way that it does not evaporate, for a week or more. If you noticed the standing water immediately after a rainstorm, it is likely that you don’t need to worry about it. You can still take steps to reduce the amount of water, but know that it likely will not affect the health of your roof. However, if there is a lot of water, typically over one inch deep, your roof can start to show wear from the increased stress. If, after a week without rain, there is still standing water on your roof, it’s time to give your local roofing company a call.
There are a few options you have that can minimize the amount of standing water on your roof. The first option is to make sure that the roof is properly pitched to encourage water to flow towards the drains. This can be done by installing a slight slope or by adding a layer of insulation to the roof to create a slight rise. Another important step is to keep the roof's drainage system clear of debris. This includes cleaning out the gutters and downspouts to ensure that your home’s drainage system is not blocked.
Another option to prevent standing water is to install a roof membrane system. A roof membrane is a layer of material that is applied over the existing roofing surface to create a barrier that prevents water from penetrating the roof. There are several types of roof membrane systems available, including single-ply, built-up, and modified bitumen. Each of these systems has its own unique benefits, and choosing the right one will depend on the specific needs of your roof.
Lastly, regular maintenance is crucial to preventing standing water on a flat roof. This includes regular inspections of the roof and drainage system, as well as regular cleaning of the gutters and downspouts. It is also important to address any leaks or other issues as soon as they are discovered, as even small leaks can lead to significant damage if left untreated.
It's important to note that if the standing water persists for more than a week, it is recommended to contact a local roofing company.
