Siding damage does more than disrupt your home’s overall aesthetic appeal. Besides highlighting the deterioration of your home, damaged sidings can also expose your home’s other external components to structural vulnerabilities. This can lead to costly renovations if you don’t repair or replace your sidings immediately.

Monitoring Your Sidings for Damage

A home’s exterior components generally have a shorter life span than its internal parts. Sidings face all sorts of damage from environmental conditions, which is why they can deteriorate in different ways. This is why a homeowner must do their due diligence in assessing the quality of their sidings.

If your sidings have any of these three types of damage, they may be due for a replacement:

1. Blisters and Bubbles

Once your sidings start bubbling from the inside, it’s an indicator that water is trapped inside. This means your home’s exteriors have cracks that allow moisture to enter, and water has damaged the internal structure. Normally, your sidings would prevent this from happening to other parts of your home. However, if your sidings themselves are experiencing water damage, they may have complications preventing them from doing their job.

Keep in mind that some building materials will be more prone to water damage than others. For example, vinyl is typically weaker than cement or metal siding when encountering moisture issues. If your sidings are particularly weak against water damage, you should inspect them more often a few days after rain and snowfall.

2.Warping and Cracking

Besides water damage, your sidings are also susceptible to melting. Although your sidings won’t melt due to the sun’s UV rays, they will still warp and crack over time. These cracks generally occur on parts that are fully exposed to the sun, especially during summertime. Since these entry points limit the function of your sidings, your house is at risk of dealing with poor ventilation and water damage.

While it’s possible to repair these small cracks by applying a sealant, it’s only a temporary solution. If you have the time to get your sidings replaced, it’s best to do so while you’re not anticipating harsh weather conditions.

3.Fungus and Mold Growth

Water and heat aren’t the only variables that affect a siding’s durability; fungus, mold, and other forms of undergrowth can also weaken your sidings. These organisms can sprout anywhere that has available moisture and access to the right growing conditions. If you have cracks or blisters that allow spores to enter and water to remain, it generally follows that fungus growth isn’t too far behind.

Allowing these harmful substances to grow on your home’s exteriors can compromise the durability of your home. Besides eating away at building material, they will also promote more opportunities for water damage and leaks to reach your indoors. Pay extra attention to your sidings’ seams since spores generally find it easier to penetrate your home in these areas.


Being aware of the signs of damage of a compromised siding prevents you from dealing with more severe structural damage to your home. Thankfully, replacing your sidings isn’t a job you have to do alone. Instead of worrying about the potential expenses of your siding replacement, view it as an opportunity to strengthen your home and increase its property value.
