Composite siding is very resistant to warping that can affect some other sidings. Because of its composition, this siding doesn’t have the same risks of moisture damage that can cause rotting, buckling, and warping. Composite material doesn’t warp in high temperatures the way some kinds of vinyl siding can.

That said, composite siding is not entirely immune from moisture damage. It should still be properly installed so that moisture can properly drain from behind the siding, and protected by eaves and clean gutter so the siding doesn’t get repeatedly soaked by rain, which could lead to damage.

For the materials alone, a square of siding costs an average of $600, but prices can range from $100 to $3,000, depending on the material. Vinyl siding costs toward the lower end of that range, while real brick or stone siding costs closer to the higher end. Keep in mind that many boxes of siding contain two squares, enough to cover 200 square feet, so you may need to double your cost if you only need one square.

You should restain or refinish your home's cedar siding every three to seven years to maintain its appearance and ensure maximum protection. The precise frequency depends on several factors, including your local climate, the siding's exposure to severe weather like direct sunlight, rain, and wind, the quality of the initial stain application, the type of stain used, and the condition of the wood.

Homeowners in harsh climates with high humidity and significant direct sunlight should plan on restaining every three years, while those in milder locations can wait up to seven years. For the longest-lasting protection in particularly harsh environments, consider using an opaque stain.

If you're looking for a lower-maintenance alternative, vinyl or aluminum siding are options to consider. Although their installation cost may be higher, they don't require as much upkeep over time, which can provide more value, especially in areas with excessive rainfall or high humidity.

When moisture infiltrates your siding, it can result in deterioration and decay of the sheathing, cause structural damage to your foundation, and provides an ideal breeding ground for mold. Mold growth can lead to various health-related problems, such as itchy eyes, sneezing, allergies, and asthma. Mold and dampness commonly attract a wide range of insects, so if your siding has taken any kind of water damage, it could invite some unwelcome guests.
