Top Reasons Your Young Roof May Have A Leak

Do you own your own home? Is your roof starting to leak, even though it's only a few years old? If you have a relatively young roof, chances are good that you probably don't need a whole new one so soon. Instead, it's likely just a relatively minor issue that can be repaired quickly and easily by a professional. Here are some of the most common reasons you might have a leaking roof:

Damaged or worn flashing: When roofers replace a roof, they sometimes reuse the flashing that was already there. This flashing goes on ridges, in valleys and around any roof vents. These strips of metal help to prevent rain and other forms of precipitation from entering your home. However, when flashing is reused, the old nail holes aren't matched up exactly. This leaves holes in the metal where water can get in. Even if the flashing is completely new, roofers will also sometimes use tar to more securely bond pieces of flashing together. If the tar breaks down, water can enter your home. For this type of roof repair, your roofer will need to figure out whether all your flashing needs to be replaced, or just a specific part. The shingles around the damaged or worn flashing will need to be replaced, but not all of the shingles on your roof. 

Ice dam: Air rising up from inside your home can warm your roof enough so that the snow on top starts to melt. If your gutters are blocked by snow or autumn leaves, the water will freeze and build a dam that will block other melted water. Since this water has nowhere else to go, it will back up under your shingles and can start to leak inside your home. This roof repair mainly consists of cleaning out your gutters and breaking up any ice, so that melted snow has a place to go. However, you should also have a roofing professional inspect the area, in order to ascertain whether or not the water damage means that a section of your roof will need to be replaced. 

Attic condensation: In the winter, warm moist air within your home can rise up into your attic. Once it gets there, the moisture will start to collect on your cold roof.  Eventually, it will start to drip down as a sort of indoor rain, like the moisture on the outside of a glass of ice water. This can make it look like you have a major leak, when it's actually coming from inside your own home. For this roof repair, your roofing professional can add better ventilation to your attic area. He or she can also confirm whether or not all vents actually lead outside, as they should. As an example, the previous owners may have needed to remove a length of the bathroom exhaust pipe during the last roofing project, only to forget to replace it before laying down new shingles. After a few years of having moisture collect in the attic area, the water is only now starting to drip down into the main house.
