What Exactly Is Siding?

Siding refers to the material that covers the outside walls of your home. It acts as a protective barrier between your home’s internal structure and the external environment. Designed to shield your house from moisture, wind, snow, and UV rays, siding also prevents structural damage, mold, and energy loss.

It’s a crucial component in your home’s envelope, offering both function and aesthetics. From sleek modern finishes to traditional wood textures, siding comes in a variety of styles and materials to match your taste and home’s architecture.

Types of Siding Materials

At Pro Home Exteriors, we provide a wide range of siding options—each with its own unique benefits, durability levels, and style choices. Here’s a breakdown of the most popular types:

Vinyl Siding

  • One of the most common siding choices in Canada, vinyl is affordable, durable, and low maintenance.
  • Available in a wide range of colours and textures
  • Resistant to fading, cracking, and insect damage
  • Easy to clean with just soap and water
  • Great for homeowners seeking a budget-friendly, long-lasting solution

Fiber Cement Siding

  • A mix of cement, sand, and cellulose fibers, this siding type mimics wood or stone but with added resilience.
  • Fire, rot, and insect resistant
  • Withstands harsh Canadian winters and humid summers
  • Offers a premium, high-end look without the maintenance of wood
  • Often comes with long warranties (up to 30–50 years)

Wood Siding

  • Natural and warm, wood siding gives your home a timeless, classic appearance.
  • Available in cedar, pine, spruce, and other species
  • Can be painted or stained to match your style
  • Requires regular maintenance to prevent rot and pest damage

  • Resistant to moisture, decay, and termites

  • A growing favourite among Canadian homeowners

Aluminum Siding

  • A traditional choice that still holds strong today for its durability and weather resistance.

Key Benefits of Installing New Siding

Investing in high-quality siding offers both immediate and long-term advantages:

Weather Protection

Canadian weather can be harsh and unpredictable. Siding acts as your home’s armor—defending it against rain, snow, wind, and UV exposure.

Energy Efficiency

Properly installed and insulated siding reduces heat loss in winter and helps keep your home cooler in summer. That means lower energy bills and a more comfortable home year-round.

Curb Appeal

The exterior of your home is the first thing people see. New siding dramatically improves aesthetics, helping your home look newer and well-maintained.

Increased Property Value

A fresh, updated exterior can significantly increase resale value. Potential buyers often see new siding as a major plus.

Low Maintenance

Modern siding materials like vinyl or fiber cement require minimal upkeep—no more repainting every few years.
