What Are Garage Doors Made Of? The Most Common Materials And Its Pros And Cons

Garage doors are made of different materials, but the most common ones are steel, aluminum, wood, and fiberglass. Apart from the evident differences in their respective appearance, certain garage door components may better suit your budget, environment, and style. 

This article will discuss the frequently asked question: “What are garage doors made of?” and the pros and cons of each garage door material company.


Steel is a highly preferred garage door material because of its design versatility, durability, and price. A steel garage door is produced in a limitless variety of designs and is a less expensive, more practical option than natural wood. You can further strengthen your steel garage door with proper insulation. This would also enhance the R-value. 

Unlike a wood garage door, steel is much lighter in weight and is easier to maintain. You can opt for “wood” designs; this way, it would provide you the elegance as well as the texture of wood, with the reliability and durability of steel. 

The primary downside of steel is that it is very susceptible to rust and corrosion. Rusting along the bottom part of a steel garage door is primarily common in locations where salt is being used to de-ice during the winter season. To help prolong the life of the steel garage door, it is highly recommended to wash it at least two times a year to eliminate grime and dirt.


  • Low maintenance
  • Durable
  • Numerous design options
  • Economical


  • Resistant to dents on a moderate scale
  • Not a naturally occurring insulator
  • If scratches are not repaired promptly, they can rust.


Wood garage doors lend an air of timeless grandeur to any exterior. Due to the fact that wood is a renewable resource, it is a more environmentally responsible alternative to consider when acquiring a new garage door. Wood garage doors are a wonderful alternative for homeowners seeking a bespoke, unique appeal. 

Along with a high initial price of a wood garage door, it is necessary to consider the ongoing upkeep required to maintain its attractiveness. A wood door that is not properly maintained will warp, fade, chip, and rot.

Wood garage doors are ideally suited to climates with moderate winters. Extreme temperature variations outside and frequent exposure to moisture (from snow, rain, or humidity) could lead the wood to expand and warp as it absorbs the moisture.


  • Beautiful, rustic appearance
  • Naturally occurring insulator
  • Numerous overlay styles
  • Staining the field to create the desired appearance


  • Manual operation is complicated and time-consuming.
  • Regular maintenance is required
  • Possibility of warping, swelling, or decay


Fiberglass is the most overlooked garage door material. However, fiberglass most accurately replicates the distinct grain texture of genuine wood. Unlike wood, though, fiberglass garage doors would not shrink, warp, or fracture, making them an especially good choice for homeowners living in places with humid climates.

Fiberglass is cost-effective and only needs low maintenance. Furthermore, because it is semi-transparent, it allows for increased natural light to enter your garage.

Fiberglass is the best fit for warmer temperatures and should not be used in windy coastal areas. Not only may strong winds damage fiberglass, but they can also generate an irritating noise. Another critical factor to remember is that broken fiberglass cannot be repaired once it is damaged; the entire garage door should be replaced.


  • Will not shrink, warp, or corrode in the presence of moisture
  • Allows light to enter the garage
  • Will not contract or inflate in response to changes in temperature
  • Low maintenance


  • If destroyed, must be replaced Brittle and prone to wind damage
  • With age, has a propensity to break

Glass And Aluminum

Glass and aluminum materials for garage doors could add an eye-catching, contemporary aesthetic to a wide array of external and interior design applications. Glass and aluminum garage doors are available in anodized finishes, numerous powder coat colors, and a variety of glass selections.

Aluminum is less durable than steel due to its lesser weight. Strong winds and hail could dent aluminum, which is difficult to repair without the assistance of a professional. Moreover, it is highly suggested to insulate aluminum section rails to raise their R-value and provide additional thermal protection for the parking space.


  • Naturally rust and corrosion resistance
  • Customizable
  • Allows the maximum amount of light into the garage
  • Low-maintenance


  • R-value is low
  • Waterproofing is not complete
  • Not as durable as steel
  • Depending on the type of glass used, there may be privacy concerns.
