Sacramento Roofing: Article About Warning Signs Shingles Need Replacing
Asphalt shingles are one of the most commonly used roofing materials on the market, mostly because of how easy they are to work with and how inexpensive they are. However, asphalt shingles typically don't last as long as other materials such as slate or metal roofing. This is why it's so important for homeowners to know the warning signs that their shingles need to be replaced. When the time comes, Sacramento roofing experts can be hired to make sure the job is done correctly.
The first warning sign is curling. As asphalt shingles age and are exposed to excessive heat, they start to curl up around the edges. This is bad for two main reasons. First, it makes the shingles more susceptible to wind damage because the edges are no longer flush with the roofing deck. Second, it breaks the watertight seal that shingles are supposed to provide, making it easier for water to damage the roofing deck and potentially requiring that the entire roof be replaced.
Asphalt shingles are susceptible to damage from the sun's UV rays, and this is their biggest weakness. To combat this weakness, the shingles are covered in granules that reflect some of the sun's rays from the house.

Severe weather and frequent foot traffic can break down the adhesive that holds the granules in place. Once this happens, the material is completely exposed to the sun, accelerating the decay process and providing a perfect entry point for water.
Just like any other roofing material, asphalt shingles start to break down and become fragile. Once this happens, it's easy for the shingles to be ripped from the foundation by foot traffic, heavy winds or animals. After a shingle has become broken or completely removed from the roof, the entire system loses its ability to shed water correctly. This problem is typically caused by physical damage. If this is the case, homeowners should talk to their roofers about installing more reliable and sturdy materials onto their roofs.
Homeowners should always hire professionals to install asphalt shingles because poorly installed materials can lead to the next warning sign: buckling. Shingles that aren't installed correctly don't shed water quickly, keeping the roofs wet longer than normal. This causes the shingles to buckle, which is characterized by visible wavy distortions in the shingles themselves. Buckles make it easier for wind to rip them from their foundation and also allow water to become trapped underneath. During the winter, this can result in the formation of ice underneath the shingles, causing significant damage to the roofing deck.
