Interior water damage can be a massive headache, causing all sorts of structural damage and promoting mold and mildew growth in your home. Catching roofing leaks early is the best way to prevent such damage from happening. Knowing what some of the most common warning signs of a roofing leak are can help you determine when you should talk to a roofing contractor about repairing your roof.
One of the clearest signs that your roof may have sprung a leak is the presence of curling or damaged shingles on your roof. This happens normally as asphalt shingles age and are exposed to heavy weather conditions, but once your shingles have become misshapen and no longer sit flatly on the roof of your home, they are no longer able to keep water from flowing into your attic. If you notice that a significant number of shingles have curled or buckled, it may be worth talking to a roofing contractor to both replace the offending shingles and inspect your attic for signs of water damage.
In a similar line of thinking to the above point, you should also inspect the flashing on your roof for signs of rust and damage. Flashing is the metal seal that is placed around the base of attic vents, your chimney and other things that jut outwards from your roof. Over time, it can begin to rust away because of constant moisture exposure. Once you can see a gap between your flashing and the base of whatever it is installed against, your roof is likely leaking from that point. Repairing the flashing can close the leak, but be sure to check your attic for signs of water damage.
Staining and Discoloration
Another relatively easy to spot sign that your roof may be suffering from a leak is if there are discolored or stained spots in your home that seemingly spring out of nowhere. Keep in mind that roofing leaks will not be limited to staining your ceilings and the upper part of your walls: depending on where the leak originates, the water can travel a significant distance behind your walls and ceiling before it becomes visible – leaks around the baseboard are uncommon but still possibly related to a roofing leak, especially if your wall has a chimney installed in it at some point. You'll have to get a roofing contractor to come in to inspect your water damage and determine the source of the leak.
