Tennessee offers beautiful scenery, but also comes with hot, humid summers and plenty of insects. Both decks and screened porches offer outdoor relaxation space, but they do so in different ways. An open deck offers unobstructed views and sun exposure, while a screened porch provides protection from bugs, rain, and harsh sunlight. Since Tennessee has no state income tax on wages, many homeowners are able to invest more in home improvements like decks and porches.

Here's a quick comparison to get you started:

Cost Considerations for Tennessee Homeowners

The cost of building a deck or screened porch in Tennessee varies depending on size, materials, and complexity. Here’s a general breakdown of deck costs per square foot, installed:

Screened porches are generally more expensive than open decks due to the added materials and labor involved in framing and screening. Expect to add 30-50% to the cost of a similar-sized deck when building a screened porch. This extra cost factors in framing, roofing, screening, and potentially a door.

Remember to budget for permits. Most Tennessee cities, including Nashville, Memphis, Knoxville, and Chattanooga, require permits for decks over 200 sqft or 30 inches above grade. Specific cities like Franklin (City of Franklin Building & Codes Dept), Murfreesboro (Murfreesboro Planning & Codes), Clarksville (Clarksville Building & Codes), and Johnson City (Johnson City Building Division) have their own permitting processes.

The Tennessee Climate Factor

Tennessee's climate significantly impacts the longevity and enjoyment of your outdoor space. With hot, humid summers (averaging 85-95°F) and mild winters, the materials you choose and the design you implement are crucial.

Dealing with Humidity and Rain

Tennessee gets over 50 inches of rain annually, which means moisture management is paramount. Proper drainage is essential to prevent wood rot and structural damage. Pressure-treated lumber, composite decking, and cedar are all popular choices, but each requires specific maintenance to withstand the elements. Composite decking, while more expensive upfront, offers superior resistance to moisture and rot, potentially saving you money on repairs in the long run.

Battling Bugs: A Major Consideration

Insects, especially mosquitoes, are a major nuisance in Tennessee, particularly during the warmer months. A screened porch offers a near-impenetrable barrier against these pests, allowing you to enjoy your outdoor space without constant swatting and bug spray. This is a significant advantage over an open deck. Screened porches are particularly popular in Tennessee because of this.

Sun Exposure and Shade

While enjoying the sun is appealing, the intense Tennessee sun can make an open deck unbearable during peak hours. A screened porch offers shade and protection from harmful UV rays, making it a more comfortable space during the hottest parts of the day. Consider the orientation of your deck or porch to maximize shade and minimize sun exposure.

Lifestyle and Usage

How do you envision using your outdoor space? This is a crucial question to answer when deciding between a deck and a screened porch.

Entertaining and Socializing

An open deck is ideal for grilling, sunbathing, and hosting large gatherings. The open design allows for easy movement and interaction. However, you'll need to consider providing shade with umbrellas or pergolas.

Relaxation and Quiet Enjoyment

A screened porch is perfect for relaxing, reading, dining, and enjoying the outdoors in peace. The screened enclosure provides a sense of privacy and protection from the elements, making it a more comfortable and inviting space for quiet activities.

Home Value and ROI

Both decks and screened porches can increase your home's value. However, a screened porch may offer a slightly higher return on investment (ROI) due to its added functionality and protection from the elements. Remember, Tennessee has no state income tax, which may lead to homeowners choosing higher-end options that improve ROI.

Material Choices: Durability and Aesthetics

The materials you choose will significantly impact the cost, appearance, and longevity of your deck or screened porch.

Wood Options

• Pressure-Treated Lumber: The most affordable option, pressure-treated lumber is resistant to rot and insects. However, it requires regular staining or sealing to maintain its appearance and prevent warping.
• Cedar: A naturally beautiful and durable wood, cedar is resistant to rot and insects. It requires less maintenance than pressure-treated lumber but is more expensive.
• Ipe: A very dense and durable hardwood, Ipe is naturally resistant to rot, insects, and fire. It's an expensive option but offers exceptional longevity and beauty.

Composite Decking

Composite decking is made from a blend of wood fibers and recycled plastic. It's highly resistant to moisture, rot, and insects and requires very little maintenance. While more expensive upfront, it can save you money on repairs and maintenance in the long run. Trex is a popular brand.

Screening Options

• Aluminum: Durable and long-lasting, aluminum screening is a popular choice for screened porches.
• Fiberglass: A more affordable option, fiberglass screening is resistant to tearing and stretching.
• Pet-Resistant: If you have pets, consider using a pet-resistant screening material that can withstand scratches and chewing.

Termite Prevention

Termite pressure is significant in Tennessee. Always ensure that ground contact treatment is applied during construction and that metal post bases are used to prevent termites from accessing the wood structure. This is essential for longevity.

Design Considerations for Tennessee Landscapes

Tennessee's diverse landscapes, from the rolling hills of Middle Tennessee (Nashville, Franklin, Murfreesboro) to the mountainous terrain of East Tennessee (Johnson City, Knoxville), present unique design challenges.

Sloped Lots

In East Tennessee, where hilly and mountainous terrain is common, elevated decks and multi-level builds are popular. These designs maximize views and create usable outdoor space on uneven ground.

Limestone Bedrock

Middle Tennessee, particularly around Nashville, Franklin, and Murfreesboro, has limestone bedrock. This can make digging footings for decks and porches challenging. Proper planning and excavation are essential to ensure a stable foundation.

Covered Decks

Consider a covered deck as a middle-ground option, providing some protection from the elements while still offering an open-air feel. This can be a good compromise if you're unsure about a full screened porch. Check out "Covered Deck Ideas for Tennessee: Beat the Heat & Rain" for inspiration.

Permit Requirements and Local Codes

Before starting any deck or screened porch project in Tennessee, it's crucial to check with your local building department to understand the permit requirements and building codes. Most cities require permits for structures exceeding certain size or height thresholds. Ensure your design complies with all applicable codes to avoid costly delays and fines. The best build months are March-May and September-November to avoid the summer heat and winter frost.
