Everything You Need to Know About Damaged Siding

Damaged siding is a common issue for most homeowners. Since broken siding allows air, water, and other debris inside, it’s important to know when to repair these areas yourself, before they cause bigger problems. Knowing how to repair small damage as it occurs is handy but knowing when to hand the job over to professionals is equally essential for quality care. Here is a look at some of the most common siding problems and how to manage them. Common problems include:


Vinyl siding may experience cracks due to old age, ultraviolet rays, cold weather conditions, and incorrect installations. Wood siding also cracks due to exposure to the elements and aging, if you do not maintain it correctly. You can repair cracks in vinyl and wood siding by simply replacing the cracked sections, but if the siding is reaching the end of its functional lifespan, you may be better off having a full replacement.


Of all the types of siding, aluminum is the easiest to dent. Aluminum siding is prone to denting by rocks, hailstorms, and contact with other debris that chips away at the surface.


Siding can become warped when incorrectly installed or exposed to strong heat sources. Vinyl siding is especially prone to warping and buckling when the temperatures get warmer in the summer, which is why it needs to be hung from fasteners to provide extra room for expansion. In general, warmer weather conditions in the summer often warp siding, whereas the cold conditions of the winter make siding more susceptible to chipping, peeling, and cracking.

Preventing Severe Siding Damage

If you notice that your siding is splitting, buckling, or becoming loose, or if you notice mold or moisture within the siding, remove a portion to get a better look. If you discover excessive moisture, the installer may have put your home’s flashing on incorrectly. In this case, you should call a professional who can assess the situation and determine the best solution. The resolution may be caulking or replacing portions of flashing or building paper.

Sealing Joints

A properly conducted siding job seals out water that could otherwise get inside and erode the siding’s sheathing. However, seals can weaken over time, so monitoring your siding’s seal is an important part of staying on top of its maintenance. If you notice any problematic areas, replace, and caulk these sections as soon as possible to reduce the risk of serious water damage.
