Shingles are among the most popular choice for roofing. They are the roofing material that is designed to protect your home from things like hail storms, high winds, and other natural elements. They come in many different shapes and sizes and can be made out of materials such as asphalt or fiberglass. When well maintained, they can last through many seasons.
However, if you notice a shingle starting to peel off the roof of your home, then it’s time for roof repair. In this blog post, we will discuss 5 common issues with shingles that may need replacing or repairing so you know what to watch out for.
1. Erosion of the Top Layer
Generally speaking, shingles have a base made of paper or fiberglass and a top layer of ceramic. The upper part has granules that protect against the harsh elements of the weather. Without it, your roof will quickly succumb to the effects of exposure.
If there is granular loss, you may notice discoloration on your roof. The problem could be due to inadequate insulation, which allows the temperatures of the tiles to rise. The heat can melt shingles, allowing the granules to flow away.
2. Blistering During the Summer
Another common roof repair problem for shingles is blistering. One sign of blistering is when there is a bald spot on the tile. It is most likely to happen in summer due to the high temperatures.
In summer, the granular layer can trap moisture under the top layer. The pressure then forces the shingles to burst open, leaving a bare area. Insulation can increase incidences of blistering. Another factor is low-quality roofing materials from the shingles manufacturer.
3. Shrinkage and Warping
As shingles approach the end of their life, they may start warping or changing shape. The most prevalent shrinking is when the edges lift upwards, forcing the tile to curve inwards.
Warping is also likely to happen due to what roofers refer to as thermal shock. That is when the temperatures fluctuate suddenly between extremes. Ventilation problems can also increase the risk of a thermal shock.
4. Installation and Premature Cracking
As they age, it is natural for shingles to succumb to cracking. But other factors can also speed up the process besides aging. If the underlying structure is shifting, the movement will cause the tiles to get worn out faster.
However, cracking is less common in newer tiles. It could either be an issue with the roofing installation or inadequate ventilation. The material from the shingles manufacturer may also be of low quality.
5. Mildew and Mold Growth in Hot Weather
In most cases, mold, algae, and mildew are cosmetic problems for most homeowners. They leave ugly streaks of black colors on the roof. Microbial growth is prevalent in places where the humidity is high or where the structure is often under shade.
Unfortunately, extensive growth of mold and mildew can allow water to accumulate on the roof. The moisture can trigger a host of problems, from blistering to cracking. If you spot any of these problems, consider calling your local roofing company for a professional assessment.
There are two types of shingles; organic and fiberglass. The latter is more durable, with a fiberglass mat that can withstand pressure and heat. However, it also depends on the weather. Organic shingles are better suited for colder climates, while fiberglass is better for regions with high humidity. Last but not least, a quality installation is necessary for a durable, problem-free roof.
