Your roof acts as a barrier against the elements, protecting the interior of your home from harm. However, this also means that your roof will eventually suffer some form of damage and require repair and replacement. If you are conscious of the most common types of roofing damage, it can make it easier for you to look out for signs that you should talk to a roofing contractor about repairing your existing roof.
One of the most common signs of roofing damage is when your shingles physically turn upwards. This is caused by moisture exposure and heavy winds, and as your shingles age they will pull away from the surface of your roof, making leaks more likely. Further, curling shingles are more likely to be torn off by strong gusts of wind.
You should also keep an eye out when cleaning your gutters for signs of black granules that may have accumulated. These are small parts of your shingles that wear away with time as the weather and sun take a toll. Seeing a few granules doesn't mean anything, but many throughout your gutters indicate that your roof is likely very old and worn down and should be replaced soon to prevent a leak from developing.
Though it may seem like a minor indication of roofing trouble, you should always keep an eye out for signs of discoloration to your shingles. Darker shading can indicate that moisture on your roof has led to algae and mold growth, which can spread into your attic and degrade your shingles at a faster rate than normal. Usually, installing zinc strips on the peak of your roof and washing your affected shingles can help remove and prevent algae and mold damage from setting in. In some cases, you may want to trim back overhanging trees as well to ensure that your roof is not shaded from direct sunlight, which can also help prevent mold and algae growth in the future.
An oft-overlooked type of roofing damage is damage to your flashing. Flashing is installed on your roof around the base of your chimney, roofing vents, and other rooftop installations that extrude out from the surface of your roof. It can be made of plastic or metal and forms a seal that prevents leaks and interior water damage. Look for signs of rust on metal flashing, and cracks or other forms of physical damage that can affect plastic flashing. In general, you'll want to repair any flashing that has separated from the side of the installation it is installed on, and you'll want to repair any flashing that is missing screws or fasteners that would hold it in place.
