Whether your roof is old or has visible damage, you may start to wonder whether it has started to leak without you noticing any overt signs, such as water streaming in through the ceiling. If so, look for the following signs in the interior of your home that may mean you have a hidden leak coming from your roof.
1. Discolorations on the Walls or Ceiling
One sign that you should look for when you suspect that your roof has a hidden leak can be found on the surfaces of the walls or ceilings of your home. Even if water is not seen streaming into a room, it could be leaking in the space above the ceiling or between the boards of the walls.
As the water collects in these spaces, it will eventually leech into the wood, drywall, paint, and wallpaper. Once this happens, the water will stain the surfaces, causing them to become discolored.
At first, these discolorations may only be evident as a slight darkening of the paint or wallpaper. However, as the water pulls in dust and dirt through the spaces in the walls and ceilings, the discolorations may take on a brownish tint.
2. Strong, Musty Odor in One or More Rooms
Along with discolorations on your home's interior walls and ceilings, another sign that may indicate a hidden water leak from your roof is the presence of a strong, musty odor in one or more of your rooms. This smell is often indicative of mold or mildew that may be growing in the hidden spaces in your home.
Because these spaces are enclosed, air cannot reach the wet wood and drywall. When this constant moisture is combined with the ever-present darkness of these spaces, mold and mildew can easily grow in the environment.
Especially if the musty odor is noticed along with discolorations of the walls and ceilings, these signs are a good indicator that you have a leaking roof. You may even start to see some fuzzy growth on the spots on the walls and ceilings as the growth pushes its way through the drywall.
If you notice either or both of the signs above and suspect that your roof is leaking, you need to have it inspected as soon as possible to avoid further unseen damage. Call and set up a time with a roofing contractor so they can come to look at your roof and discuss your options for either repairing the leaking portion or replacing it.
