siding installation can impact whether it will warp

6 Reasons Why Your Vinyl Siding is Warping

For many homeowners, vinyl siding is a popular option for protecting the exterior of the house. Not only is it incredibly affordable, but it is also versatile and very easy to maintain. However, even though it is relatively weather resistant, it can be warped over time. 

It is important to understand what can cause siding to warp to know how to prevent it. This will save you money and time in the long run!

Improper Siding Installation

Improper installation is one of the reasons vinyl siding may begin to warp. When siding installers set the vinyl, they may nail it down too tightly. When this happens, bulging can occur. Siding tends to fluctuate with changing temperatures making it prone to becoming damaged. While some siding professionals may believe that nailing it down tightly will make it last longer, it can ultimately have the opposite effect.

make sure your siding is installed properly to avoid warpingVinyl siding is designed to be installed so it can move and adjust to the weather and external conditions. To check to see if your siding is nailed down too tightly, try moving it slightly. If installed appropriately, it should be able to shift around half an inch from side to side.

The nail placement can also affect the vinyl and warping. Typically, the nails should be placed in the middle of the oval-shaped openings. This will be at the top of the panels. This portion is designed for nails, ensuring they are not too close to each other. In the end, this allows for the vinyl to shift slightly. 

In addition, it is also important to keep shutters separate from the vinyl. Shutters are not meaning they are not nailed directly to siding.

Temperature Changes

Heat is another culprit of warping vinyl. Since vinyl is plastic, it can melt if the external temperature is too high. Furthermore, vinyl that is naturally darker or painted in darker colors is more prone to warping because they tend to absorb more heat.

If you live somewhere relatively warm where temperatures are a concern, consider a lighter color vinyl that will reflect heat instead of absorbing it. Placing a gas grill near your home is also not advisable due to its high temperatures when in use.

Siding Alignment

Poor alignment is another leading cause of vinyl warping. If the ends of the panels are too close to the trim of the windows or the corners of the house, the vinyl cannot move. It may warp if the vinyl cannot naturally shift (expand or contract) with the temperature. 

Pests

While this is not a common source of vinyl warping, it can occur. Some pests could cause distortion when they burrow underneath the house siding. One of the most common types of pests that do this is termites. They may even consume part of the siding if not taken care of. This damage can affect the house’s structure, causing the panels to warp. The gaps can widen if your siding begins to warp, allowing more pests to get in.

Reflections

strong reflections can warp your sidingOne cause of warping that often surprises people is the reflection from Low-E glass nearby. Whether it is a part of your home or someone else’s, this material can cause warping. This type of glass is an energy-efficient material that diffuses UV rays to prevent them from entering the home. However, that can make UV rays reflect off the house and onto the vinyl, causing it to warp.

Luckily, this is easily preventable. An external screen attached to the window helps prevent that reflection back onto the home. Vegetation like a plant or tree can also help block this light.

Low-Quality Siding

While vinyl is very affordable, homeowners should know what they are getting. When buying parts for a home, many people want to save as much money as possible. However, consider choosing reasonably thick and durable vinyl siding. Cheaper panels are typically much thinner and potentially wavy, which can cause issues once installed. Thicker ones will be more durable and last longer.
