10 Things that Can Damage Your Roof (Part 2)


In the last blog, we talked about five major causes of damage to roofing systems: wind, trees, debris, malfunctioning gutters and downspouts, and animals. Today, we will take a look at five other factors that can cause roof problems. It is important for homeowners to be aware of each one of these issues and to act quickly when they arise. By being educated about potential problems, you will be able to spot damage more quickly and save a lot of time and unwanted expense.


6. HailHail damage can often be difficult to diagnose on a roof. It can be hard to spot until it worsens and begins to cause major problems for your roofing system. Hail sometimes produces large, clearly visible punctures, while other times, it creates only small, hairline cracks, which are very difficult to spot. For roofs with asphalt shingles, small cracks in the roof's surface will allow water to flow into the roofing system and knock out granules from shingles, gradually causing more and more damage over time. Hail can also damage the coating on shingles, leaving bare spots that expose the roof to the elements of nature. Ultimately, if no action is taken to repair areas that are vulnerable to UV rays and moisture, this will shorten a roof’s lifespan. If you roof has endured a hail-producing storm, it may be wise to call in a professional roofing contractor to carefully inspect your roof for damage.


7. Ice & Snow—In and around Iowa, we have to worry about snow and ice and the troubles they can bring us during the winter. They aren’t just a pain when we’re out driving around; they can also pose problems at home. Snow or ice buildup on a roof can cause significant damage. Sometimes the weight from the buildup compromises the roof’s structure by putting extra stress on certain areas. The worst damage, though, is usually caused after freezing, melting, and then refreezing. When ice melts, water can seep into areas of the roof. When it refreezes, the water expands, and ice dams form. When the ice expands as it refreezes, it can lift structures of the roof, leading to water intrusion and leakage through the roof and into the home.


8. Sun—The sun usually causes damage to a roofing system in places where the roof is already damaged or left vulnerable. Exposed areas, such as places where shingles have fallen off, are where the sun can cause the most harm. On older roofs, the sun can also crack or dry out shingles. When a roof starts to show signs of aging, it may mean that it is time to install a new roofing system.


9. Flashing—The flashing around structures or projections that intersect with the roof, such as chimneys, vents, or skylights, is meant to seal and protect jointed areas from water penetration. If flashing is dried up or damaged, water can seep into the roof and through the ceilings of your home. In general, good flashing should be able to sustain these areas of a roof and hold up against rain and ice, but as a roof ages and begins to deteriorate, so does its flashing.


10. MOISTURE—Ultimately, it almost always comes down to the same problem: moisture. Moisture is at the root of most roof damage. This means that when other problems occur, it is very important to deal with them as soon as possible to prevent the damage that is sure to follow when areas of the roof are exposed to moisture.
