Discolored spots on the ceiling, peeling paint and rotting wood are all obvious signs of a roof leak. If you are keen, you should suspect a leak long before it gets to that point. Some of the less obvious signs that should make you suspect a leak include the presence of:
Algae and Mold
Mold and algae thrive in moist areas, and they don't need a lot of water to sprout up. Therefore, if you notice some on your roof, then there is probably more moisture on your roof than should be. This is likely to be the case if the mold spots or algae are in the attic space or around air intakes or other roof projections. The fungi are deposited onto the roof from the air, and they sprout up when they find it moist enough.
You should also brace for a leak if your shingles are cupping. This is most likely to happen if the shingles are old and the attic isn't properly vented. When the attic heats up, the shingles' undersides also heat up, and this makes their corners to turn up. This allows windblown rainfall to get under the shingles and leak into your house. It takes time, but the devastation can be overwhelming over time.
In most cases, missing shingles are occasioned by presence of critters on the roof or damage of shingle sealant. The sealant is responsible for holding the shingles in place. If the sealant fails, then the shingles can be knocked off their places by different forces such as wind. This is bad for your roof because it is the overlapping pattern of the shingles that keep out water from seeping into the roof. It is easy for a roof leak to occur once this pattern is gone.
Gaps in Flashing
Lastly, you should also be concerned about a possible leak if you notice gaps in your roof flashing. The flashing is the material that covers roof joints, such as those around chimneys and other roof projections, so that water doesn't get in. Weathering, oxidation, poor workmanship or even normal wear and tear can damage the flashing and expose some gaps. When this happens, water can get into the roof and your house.
A minor roof leak can become a major problem within a short time. Therefore, you should call a roofing contractor the moment you suspect that you will soon be dealing with a leak problem. Don't just get rid of the symptoms, for example, by cleaning mold spots. You have to fix the root of the problem if you don't want to risk replacing your roof sooner than you should.
