Summerville Roofing: Article About Diagnosing Weather-beaten Exteriors
Shingle and metal roofs are subjected to wear and tear over time, and this can result in numerous physical changes, such as discoloration, pitting and rounding. Many homeowners would rather not look at the ugly results of environmental wear, but paying attention to the type of damage your roof receives can provide you with valuable insights about how it got that way and what you can do to prevent future issues.
Discolored patches on your Summerville roofing or siding can be caused by many environmental factors. While moss and algae growth are common culprits, rust or corrosion-colored stains dripping down the side of eaves and overhangs may indicate that your roof's protective seal has been breached.
Flowing water could be washing asphalt, metal ions or other materials out of the roofing substrates, resulting in a stark stain on your building. This can also occur with flashing and other fixtures that are beginning to corrode. Calling a roofer to find the source of these stains may be the best way to stop progressive degradation before it gets really bad.
Widespread discoloration may mean that your roof or siding is becoming worn by UV radiation. While this form of color change is usually more uniform than rust staining, it's still a problem because UV degradation can also cause structural weakening. Some forms of vinyl, PVC or asphalt may become brittle faster when they're overexposed; it's important to determine whether you'll require a replacement or if you can install alternate options before the worst happens, and the damage spreads.

Your roof's texture will change with time as well. Hail storms, for example, knock out the tiny stones that figure prominently in asphalt shingles, and they can even cause pitting metal roofs. Severe hail and debris-laden winds can also create gouges or deeper scratches that remove top coat materials and compromise seals. If you notice that mosses and algae begin taking root in specific areas of your roofing after a while, it could be because these areas have lost their growth-resistant coatings.
Swelling and sagging aren't as common as the other problems, but they can occur as the result of more basic issues. For instance, roofs that allow water to enter usually experience gross distortions because the moisture they absorb makes them expand in certain spots and not others. Roofs can also start dry rotting if they don't have proper ventilation; fungi that grow inside the wood timbers and planes consume the cellulose and leave a powdery mess in their wake. Roof members may begin sagging when these phenomena reduce their load-bearing capabilities. Because the range of problems that affect roofs and siding systems is so vast, it's best to have a professional aid you as you attempt to figure out what's wrong with your home's exterior.
