3 Things That Cause Both Cosmetic And Structural Roof Problems
Posted on: 26 September 2022Share
Some things interfere with your roof's curb appeal and structural integrity. As such, you should not dismiss them as mere cosmetic problems. Below are three examples of such issues.
1. Biological Growth
Biological growth on the roof stems from different organisms. The common ones are algae, moss, mold, and lichen. Factors that contribute to biological growth include shade, moisture, and organic debris on the roof. For example, biological growth is common on roofs surrounded by tall trees since they shade and litter the roof with organic debris.
Biological growth discolors the roof and interferes with your home's curb appeal. With streaks or patches of organic matter, your roof might look like an amateurish mix and match of materials.
Biological growth on the roof causes damage in different ways. For example, the growths absorb and retain moisture, which can penetrate the roof or degrade the materials. The materials also encourage rot and decay, for example, on wooden parts of the roof.
2. Missing Granules
Asphalt shingles have granules that mitigate ultraviolet (UV) damage on the roof, improve roof aesthetics, and provide friction to those who walk on the roof. As such, the loss of shingle granules interferes with your roof's aesthetics and structural integrity.
For example, shingles come in different colors, mainly from granules. Thus, your roof will lose its characteristic color if it loses granules. The appearance might even be worse if the loss occurs in patches, as is usually the case. In addition, bald shingles will be more susceptible to damage than others with intact granules will.
3. Missing Shingles
A roof with missing shingles looks unkempt and old, even if the rest of the roof is sound. Beyond the aesthetic concerns, even a few missing shingles can lead to further costly damage. For one, the missing shingles make it easy for the wind to get under the remaining shingles. Strong winds can rip more shingles off a roof that already has missing shingles.
Secondly, shingles protect other roofing layers, such as underlayment, from storm debris, hailstones, and even animals. The risk of damage from such threats increases with the loss of roof shingles. Common causes of shingle losses include poor installations, material defects, aging, and weather damage.
Always consult a roofing contractor if you notice roof alterations or defects, even if you don't understand their implications. The contractor will evaluate the changes to determine and execute the necessary interventions. The more you delay repairs, the more the problems will worsen.
