Water trapped on a flat roof can be very problematic because water is very heavy and can do structural damage. Knowing what to do to drain the water can help you maintain your flat roof throughout the year.
What does it mean if there's water trapped on your flat roof?
The presence of water indicates that the roof's drainage system is not working properly. In the spring, this may be because of a clog caused by dead leaves from the previous winter and fall.
What can you do to get rid of the water?
You can get rid of the water on your flat roof by unclogging the drain. To do this, you'll need a plumber's auger. Climb up on your flat roof and locate the drain under the puddle of water. Remove any leaves and debris hiding the drain grate, and then remove the grate entirely.
Stick the tip of the plumber's auger into the drain. Use the crank to push the tip of the auger deeper into the drain until it reaches the clog. When the auger reaches the clog, it will dislodge it and allow the water to flow through the pipe. When the water has drained from the roof, run a hose up to the roof and spray down into the pipe with a strong jet of water. This will help clear the drain of any remaining debris.
When you're finished, have a professional roofer take a look at the roof. Depending on how long the standing water was trapped on your roof, there could be damage to the structure. A professional roofer will be able to identify leaks and new weaknesses in the roof.
What can you do to prevent your roof from gathering water in the future?
You can prevent water from becoming trapped on your roof in the future by periodically sweeping up leaves and removing debris before it flows down the drain. Inspect your flat roof every season and remove what doesn't belong.
In addition, cut down any branches that overhang the roof. This will prevent the leaves from gathering on your roof in the first place.
What should you do if you're unable to drain the water off of the roof?
If you can't get the drain to unclog, or if the drain is unclogged but there are still large puddles of water on your roof, contact a professional roofing company. Your roofer can assess the problem and make repairs as necessary.
