What Are the Benefits of Vinyl Siding?

Vinyl siding is widely favoured by homeowners and builders for its long-lasting durability and minimal maintenance needs. It also comes in a palette of shades and styles, making it an excellent choice for virtually anyone.

Here are some of its main benefits:

• Durability: Engineered to endure extreme weather conditions, including high winds, heavy rain, and hail. Unlike wood, it won’t rot, warp, or be affected by insect damage.
• Low maintenance: Requires no painting, staining, or caulking. A quick wash with vinyl-safe soap and water keeps it looking new for years.
• Cost-effective: More affordable than other exterior options like brick or wood in terms of material and installation costs.
• Energy efficiency: When paired with insulated vinyl panels, it reduces thermal bridging, helping maintain consistent indoor temperatures.

Is Vinyl Siding Waterproof?

Vinyl siding isn’t waterproof, but it is water-shedding. It’s designed to deflect most rain while allowing ventilation and drainage through built-in gaps and weep holes. That’s why a properly installed weather-resistant barrier and flashing system behind the siding is key to protecting your home from moisture damage.

What Are the Different Types of Vinyl Siding?

Vinyl siding is manufactured in several distinct profiles, each serving different structural or aesthetic purposes.

These are the most common profiles you’ll see:

• Clapboard (or traditional lap): The most common horizontal profile. Boards are installed in an overlapping fashion to create a clean, uniform look. Standard dimensions range from 4” to 8” reveal widths.
• Dutch lap: Similar to clapboard, but with a bevel at the top edge of each board to create shadow lines. It’s often chosen for its dimensional appearance.
• Board and batten: A vertical siding style that alternates wide boards and narrow battens. It’s frequently used for accent walls or farmhouse-style homes.
• Shake and shingle: Mimics the look of hand-split cedar shakes. It’s available in straight or staggered edge, ideal for gables or decorative sections.
• Beaded seam: Features a distinctive rounded bead at the bottom of each panel. It’s often found on historic or Southern-style homes.

You can also get insulated vinyl, which comes with a rigid foam backing (EPS or graphite-enhanced EPS) laminated to the panel. This adds minor R-value and structural stability while reducing thermal bridging.

Each style is available in various gauges, with thicker grades offering improved impact resistance and better dimensional retention.

How Long Does Vinyl Siding Last?

Vinyl siding's longevity is largely determined by its quality, detailed installation, and exposure to environmental elements. It generally lasts 20 to 40 years, but premium options often exceed that timespan.

Proper installation techniques and routine maintenance, such as periodic cleaning and inspection, are essential for preserving its structural integrity and maximizing its lifespan.

How To Tell When Vinyl Siding Needs To Be Replaced

Vinyl siding should be evaluated annually for signs of failure or weathering.

Common indicators that replacement is warranted include:

• Warping or buckling: Often due to improper installation, such as overdriven nails or lack of expansion clearance. Warped panels compromise water shedding and can lead to moisture intrusion.
• Cracks or brittleness: Typically appear after long-term UV exposure or impact. Cold weather makes this issue worse. Cracks can allow water to penetrate the substrate.
• Fading and oxidation: Severe colour fading or white chalky residue (oxidation) indicates UV degradation. While not always structural, it's often a sign the siding is nearing the end of its service life.
• Loose or missing panels: Wind or age can cause panels to disengage from locking mechanisms. Repeated occurrences suggest weakened fasteners or panel fatigue.
• Mold, mildew, or moisture damage: Persistent moisture behind the siding may indicate poor ventilation, inadequate flashing, or compromised underlayment—all reasons for replacement.

A siding audit from one of our qualified installers can determine if isolated repairs are sufficient or if a full replacement is the more cost-effective long-term.

How Is Vinyl Siding Installed?

Vinyl siding installation is a detailed, multi-phase process that requires accuracy and expertise to achieve a durable, professional finish.

This is our process:

• Surface preparation: Repair any damaged sheathing or framing and ensure the exterior surface is clean, dry, and structurally sound.
• Weather-resistant barrier: Apply a moisture-resistant barrier to protect the underlying structure and prevent mold growth. In some cases, foam board insulation is added under the vinyl siding.
• Starter strips and panel installation: Install starter strips at the base of the walls to anchor the first row of panels.
• Trim and finishing touches: Add trim pieces such as corner posts, J-channels, and soffit panels for a polished look.
• Accessory installation and inspection: Install accessories like shutters, light blocks, and vents. A thorough inspection ensures the installation complies with manufacturer guidelines and local building codes.

Can You Install Vinyl Siding in the Winter?

You can install vinyl siding in the winter, but it takes extra care. Cold temperatures make vinyl more brittle, so our installers adjust how they handle, cut, and fasten the panels to prevent cracking or warping later on. Proper spacing and flexibility during installation also help avoid issues once the weather warms up.

While warmer, snow-free conditions are ideal, siding replacements don’t always happen on a perfect schedule—so we're equipped to install it safely and correctly any time of year.

Do You Need Insulation Under Vinyl Siding?

Insulation under vinyl siding is not mandatory but significantly improves energy efficiency by reducing thermal bridging and maintaining consistent indoor temperatures. It also enhances impact resistance and provides a smoother finish, making it particularly beneficial for older homes or those in harsh climates.

However, if your home is already well-insulated, adding vinyl insulation may offer minimal benefit and could be an unnecessary expense.
