Your garage door works hard every day — opening and closing thousands of times a year. But how long can you expect it to last before it needs replacing? The answer depends on how it’s used, how well it’s maintained, and most importantly, what it’s made of.

If you’re a homeowner in Lawrenceburg, Savannah, Spring Hill, or surrounding areas, here’s what you should know about the lifespan of garage doors by material and how to extend it.

🪵 Wood Garage Doors

Lifespan: 15–20 years (with proper maintenance)
Pros: Beautiful, classic look that adds warmth and curb appeal.
Cons: Prone to weather damage, rotting, and warping if not regularly sealed or painted.

Wood doors require the most maintenance. Regular refinishing is key to keeping them in good shape, especially in areas with high humidity or rain.

🔩 Steel Garage Doors

Lifespan: 20–30 years
Pros: Durable, low-maintenance, resistant to warping.
Cons: Can dent easily, and older models may be prone to rust if the finish is compromised.

Steel is one of the most popular choices for homeowners in Tennessee due to its durability and wide range of styles. Galvanized steel options with baked-on finishes hold up especially well.

🧊 Aluminum Garage Doors

Lifespan: 20–25 years
Pros: Lightweight, rust-resistant, and modern in appearance.
Cons: Less impact-resistant than steel and can dent more easily.

Aluminum is great for homeowners near humid areas like Muscle Shoals or Savannah, where moisture is a concern.

🧱 Fiberglass Garage Doors

Lifespan: 20–30 years
Pros: Rust-resistant, lightweight, and can mimic the look of wood.
Cons: Can crack in very cold temperatures and may yellow over time.

Fiberglass doors work well in moderate climates and require less maintenance than wood, but they can become brittle if exposed to harsh winters.

🏗️ Vinyl Garage Doors

Lifespan: 20–30 years
Pros: Dent-resistant, low maintenance, weather-resistant.
Cons: Limited style options and may fade over time.

Vinyl garage doors are a strong choice for families who want a tough, kid-proof option that holds up to everyday wear and tear.

🧰 Other Factors That Affect Lifespan

• Usage frequency (the more often you open/close it, the quicker parts wear out)

• Climate exposure (rain, wind, extreme temps)

• Maintenance habits (regular lubrication, inspections, and part replacement)

• Quality of installation and hardware
