When you're dealing with a flat roof, one of the most common problems that you will run into is water drainage problems. Pooling water on a flat roof can lead to prolonged water damage, which can threaten the structural integrity of the roof. To avoid problems like this, you'll want to work with a roofing contractor to set up a drainage system. Here are a few of the options you can consider.
You should always have gutters installed with flat roofing. They will collect the water that does run off, and will route it away from the roof. The downspouts installed on either end will allow the water to flow away from your house. The best part about gutter systems is that they don't require any modification to the roof at all. They're mounted along the edge of the roof, so the existing structure isn't disturbed. Depending on how your roof is designed, you may need to modify it slightly to add a miniscule slope that will encourage the water to run to the gutters, though. The downside to gutter systems is that you have to keep them clean. If they get clogged with leaves, they won't function as intended.
Leveling For Low Spots
If you've inadvertently ended up with any low spots in your roof, a leveling approach can help. Leveling will fill in the low areas so that the roof is smooth. Insulation and filler material are used to address the low spots, then the roof should be topcoated to seal everything and preserve the integrity of the waterproofing.
Internal Drain System
Internal drains need to be installed when the roof is put in, so you'd want to consider this when you have the roof replaced. The internal drains are placed in different areas of the roof, then the flat roof is designed with a minimal slope so that the water on the roof flows to these drains. If you're not ready to replace your roof, your roofing contractor can install some drains in areas where you already have pooling water. This can address the immediate need until you're ready for a full internal drain system.
Rubber roofing membranes are placed over the top of the existing roof. It provides waterproofing on the surface, repelling water so that it flows toward the outer perimeter. When installed with a gutter system, this is a quick and easy solution that protects your roof and helps you keep the water at bay. The long lifespan for rubber roofing makes it a great investment, too, because you won't have to replace it as often as you would other roofing materials. And since rubber roofing is designed to withstand even harsh winter climates, you can opt for this no matter where you live.
Scuppers are another affordable option for dealing with water drainage. They are installed at the low points of the roof. The rainwater flows through the openings crafted into the scuppers, where it's then routed to a downspout system that routes it away from the house. This keeps water from running down the walls or accumulating around the foundation. You can direct the downspouts in any direction necessary to keep the water flowing away from your property.
As you can see, there are many ways to deal with pooling water around your flat roof. If you're not sure what the best option would be, you can talk with your local roofing contractor from companies like Palmer Roofing.
