Wet Areas Showing Up In Your Ceiling? Check The Tiles On Your Completely Flat Roof

If you notice large, wet spots showing up in your ceiling, and you can't find any visible leaks in the material, check the tiles on your completely flat roof. Flat roofs may develop leaks and other issues over time. The problems usually happen when water or melting snow puddles or ponds on the surface of the roof. The water eventually seeps through your roof's substrate and into the ceiling. Here are things to know about puddling water and what you can do to stop it.

What's Ponding Water?

Your completely flat roof doesn't have enough slope, or pitch, to allow water to drain from its surface, which leads to ponding. Ponding is a term used to describe water that doesn't dry up within a certain amount of time. The water forms large puddles instead. When ponding occurs on flat roofs, the water generally takes two days or more to dry up. If it rains during that time period, the puddles increase in depth and size.

Puddling water has a tendency to seep beneath roofing tiles and shingles, which can place your roof and the structures beneath it at risk for sagging, deterioration and other problems. If you stand out in the yard and examine the top of the home from different angles, you might notice that it sags in places, appears uneven or somewhat lopsided. The wet tiles and puddling water may weigh down your roof, which creates hazardous conditions if it collapses.

The best way to avoid or stop the issues above is to prevent water from ponding on the roof in the first place.

How Can You Keep Water From Ponding on Your Roof?

One of the steps you may take is contact a professional roofer for help. The contractor will most likely repair the ceiling and membrane covering the roof deck before working on the slope. If the damp ceiling and membrane aren't removed and repaired, they may encourage wood rot and mold to develop in the home. After they complete the repairs, the contractor may use rigid foam insulation to create the slope. The foam usually features thin or tapered edges that allow water to flow from the roof, through the gutters and down the downspouts.

If your current tiles are too damaged from the puddling water, you may expect to replace them. It's probably a good idea that you select material that comes with a waterproof coating to help ward off water and moisture. The contractor may have a list of ideas for you to go over when they visit your home.
