What Are the Main Options for Under Deck Covers?
There are five main types of materials used for under deck ceilings:
- Wood
- PVC and vinyl
- Metal
- Fabric and canvas
- Synthetic wood composites
Each has their own advantages and disadvantages. Here’s an overview of the key benefits of each option:
Wood
Wood, such as cedar or redwood, is a traditional choice for under deck ceilings. The benefits include:
- Natural appearance – Many homeowners prefer real wood for its beauty.
- Durability – Wood holds up well over time.
- Customizable – Wood can be stained, painted, or left natural.
PVC and Vinyl
PVC and vinyl are synthetic materials that are moisture-resistant and low maintenance. Pros of PVC/vinyl include:
- Affordability – PVC and vinyl panels are often cheaper than wood.
- Low maintenance – They don’t require staining or frequent repairs.
- Moisture resistance – PVC and vinyl won’t rot or warp due to moisture.
Metal
Metal under deck panels like aluminum are another option. Benefits of metal include:
- Durability – Metal is very strong and long-lasting.
- Moisture resistance – Metal won’t absorb water or swell.
- Fire resistance – Non-combustible.
Fabric and Canvas
Fabric and canvas options for under deck ceilings include:
- Acrylic Sunbrella – Treated canvas resistant to fading.
- Olefin fabric – Outdoor upholstery fabric that sheds water.
- Porous fabrics – Allow airflow but not water.
Benefits include:
- Aesthetics – Fabrics come in a wide variety of colors and patterns.
- Lightweight – Easy to install.
- Outdoor-friendly materials.
Synthetic Wood Composites
Composite wood decking planks can also be used for under deck ceilings. Pros include:
- Realistic wood appearance without maintenance.
- Durability – Won’t rot, crack, or warp.
- Stain/fade resistance.
Main Considerations When Choosing an Under Deck Covering
When selecting a material for your under deck ceiling, there are several variables to take into account:
Climate
Your geographic location and local weather patterns should factor into your decision:
- In damp climates, prioritize mold/mildew resistant materials like vinyl, composite wood, or metal.
- In areas with heavy rain, snow, or humidity, ensure adequate drainage with angled panels.
- In arid climates, moisture resistance is less critical.
- Consider sun exposure/UV rays when choosing fabrics or wood stains.
- Cold climates may require insulation under panels.
Usage
How you intend to use the space under the deck will affect your choice:
- Storage space – Prioritize durability and moisture resistance.
- Outdoor kitchen – Focus on aesthetics and easy-to-clean surfaces.
- Kid’s fort or play area – Soft, fabric coverings will add comfort.
- Grilling area – Fire-resistant metal is a must.
Cost
| Material | Cost per Square Foot (Installed) |
|---|---|
| Basic PVC/Vinyl | $3 – $7 |
| Pressure-Treated Wood | $15 – $30 |
| Cedar | $30+ |
| Composite Wood | $15 – $25 |
| Aluminum | $10 – $20 |
| Acrylic Canvas | $5 – $10 |
Less expensive options include basic PVC panels and canvas. Wood, composite, and metal cost more but also tend to be more durable.
Appearance
Factor in how much the aesthetics matter for the space:
- Wood or composite have an attractive, natural wood look.
- Canvas allows for color and decorative patterns.
- Metal and plastic have a more utilitarian appearance.
Pitch/Slope
The angle or pitch of your deck will impact the best covering option:
- Low pitches are prone to standing water – prioritize drainage.
- Steep pitches allow water runoff but may require sturdier anchoring.
Weight
Material weight factors into installation method:
- Heavy wood or metal panels require secure attachment to joists.
- Lightweight canvas can be hung with grommets or hooks.
Flammability
If used near open flames, prioritize fire-retardant materials:
- Untreated canvas is highly flammable.
- Wood can be treated with fire retardant chemicals.
- Metal is non-combustible.
