Roof leaks are not fun, and many people take comfort in locating the potential source because they at least know that it can be fixed, and that they won't have to deal with a mystery leak forever. However, there are a number of roof-leak myths that perpetuate and that complicate attempts to locate the source of the leak. If you know the truth behind these myths, you'll find those mysterious roof leaks are a lot easier to find and eliminate.
A Ceiling Leak Means There's a Roof Leak
In most cases, a ceiling leak on the top floor of a building means there is a roof leak somewhere. But that's not always the case.
When wind drives rain into the side of a building, any weak spots in the building, such as bad caulking around windows, can let the rain seep in there and leak inside the adjacent room. If the rain enters a weak spot along a seam in the building, such as the lines you sometimes see between floors in apartment buildings, then leaks can appear in the ceiling in lower floors. All you need to do is to get someone to caulk those weak spots. The problem is that not many people realize that rain can seep in through a side of the building, so they tromp all over the roof, damaging the material up there, looking for non-existent holes.
Metal Roofs Never Leak
Metal roofs, when properly installed, are very tough and hard to damage. However, improper installation, such as crooked screws and bad sealant, can lead to water seeping through. These can be tougher to locate because you have to go over all of the sealant and all of the screws (as well as all of whatever else can go wrong if the roof isn't installed well) to find each problem spot. But once you find the problem, it's usually easy to fix.
The Roof Leak Is Right Over the Ceiling Leak
Many people believe a roof leak is right over a ceiling leak, but that's not usually what happens. When water drips in through the roof, it pools on the floor of the crawlspace or attic (whichever your house has) and then runs to the lowest point in that floor. The resulting pool gradually damages the floor and allows water to start seeping through. So, a leak in your kitchen ceiling could be the result of a leak in the roof by the front door.
No matter the cause of the leak, a roofing company can locate the problem and fix it, allowing you to enjoy your home, rather than cover everything with plastic. Roof leaks don't have to by mysterious and annoying -- get to them early, and you can keep the resulting damage very small.
