What type of siding commonly experiences warping due to heat?

1. Metal siding

2. Vinyl siding

3. Wood siding

4. Stucco siding

The correct answer is: Vinyl siding

Vinyl siding is particularly susceptible to warping due to heat because it is made from polyvinyl chloride (PVC), a material that can soften and deform at elevated temperatures. When exposed to direct sunlight, especially in hot climates, vinyl siding can become significantly warmer than the air temperature, leading to a risk of bending or buckling. Unlike metal siding, which can handle high temperatures without significant deformation, or wood siding, which can experience other forms of damage like rot or insect infestation but not typically warping due to heat, vinyl's chemical properties make it vulnerable to thermal expansion. Stucco siding is also less prone to this issue, as its mineral composition allows it to withstand temperature fluctuations without warping. Therefore, vinyl siding's specific material characteristics make it the correct choice as the type of siding that commonly experiences warping due to heat.
