Advantages of Using Fiber Cement Siding for a Detached Garage


Fiber cement siding is a highly durable material that is resistant to rot, pests, and extreme weather conditions such as hail and high winds. Fiber cement siding can last for up to 50 years or more with proper maintenance.

Fiber cement siding is made from a mixture of cement, sand, and cellulose fibers, which are combined to create a strong and durable material. The cellulose fibers provide strength and resistance to cracking, while the cement and sand provide durability and resistance to weathering.


Fiber cement siding is non-combustible. It does not burn or contribute to the spread of fire. This makes fiber cement siding a safe choice for a detached garage. 

A detached garage is considered to have a high risk of fire as many flammable materials, such as gasoline, paints and cleaning solvents are stored there.

Fiber cement siding is non-combustible because it is made from a mixture of cement, sand, and cellulose fibers. Cement and sand are non-flammable materials, and the cellulose fibers used in fiber cement siding are treated with a fire-resistant chemical. 

As a result fiber cement siding can withstand high temperatures without catching fire.

Low Maintenance

Fiber cement siding is low-maintenance. It only requires regular cleaning and some basic care.

  1. Inspect the siding regularly for any signs of damage, such as cracks, chips, or loose areas. Repair any damaged areas as needed.
  2. Clean the siding periodically with a mild detergent solution and a soft brush.
  3. Check the caulking around the edges of the siding and windows and replace if necessary.
  4. Touch up any chipped or peeling paint.
  5. Avoid using high-pressure power washers, as these can damage the siding.

Finishing Options

Fiber cement siding offers a range of finishing options for those who want their garage to stand out and look unique. You can choose between:

  • Unpainted or Pre-Primed, and then paint it in the color of your choice

Relatively speaking fiber cement siding is expensive and price is in the $4 – $5 range. The final cost goes up to $8 – $12 because of significantly high delivery & installation costs. More on this in the next section.

The average weight of fiber cement siding is about 2 ½ – 3 pounds per sq. ft. compared to ½ – ¾ pounds per sq. ft. for vinyl siding. The much higher weight increases handling and installation difficulty. 

Fiber cement siding also requires the use of special cutting tools, such as a circular saw with a carbide-tipped blade, to prevent chipping and breakage.

Installation is Costly

While installing vinyl siding is a DIY project, installing fiber cement siding is not. It usually requires to be installed by professionals who are trained in the proper techniques and have experience working with the material. 

This is because it requires precise measurements & cuts and correct installation procedures.  Fiber cement siding must be properly secured and sealed. 

Handling and professional installation of fiber cement siding is often more expensive than the material cost.

Fiber cement siding is a dense, solid material that does not have any inherent insulation properties. Wood siding, on the other hand, has better insulation properties.

If you are concerned about keeping your detached garage warm in the winter, you will need to add insulation to your garage walls. Insulation will help reduce heat loss and improve the energy efficiency of the garage.
