Tennessee decks face a unique blend of environmental stress:

• High Humidity – Moisture can cause wood to swell, rot, or develop mildew.

• Strong UV Exposure – Long sunny days can cause fading and cracking in certain materials.

• Heavy Rains & Storms – Especially in spring and summer, rain can damage improperly sealed or poorly draining decks.

• Cold Snaps – While snow isn’t common, freezing temperatures can still damage inferior materials.

A successful deck design takes all of this into account—especially the materials you choose.

🛠 Best Decking Materials for Tennessee Homes

1. Composite Decking (Trex, TimberTech, etc.)
Composite decking is a top choice for Tennessee homeowners. It resists moisture, insects, and UV damage far better than wood.

• ✔ Low maintenance

• ✔ No sealing or staining

• ✔ Great in humid and wet environments

2. PVC Decking (Azek, Fiberon)
For the ultimate in moisture protection, PVC decking offers 100% synthetic construction that stands up to rain, humidity, and rot.

• ✔ Completely waterproof

• ✔ Highly fade- and mold-resistant

• ✔ Ideal for pool decks and shaded areas

3. Pressure-Treated Lumber (with caution)
Still a budget-friendly favorite, but requires proper sealing and maintenance to survive Tennessee’s climate.

• ✔ Affordable upfront

• ✔ Readily available

• ✘ Needs yearly maintenance to prevent weather damage
