If the house is feeling cramped, but the heat is keeping you indoors, a shaded spot with a fan and a comfy spot to rest sounds dreamy.

If you are considering building a second-story deck, your dream can come true with an under-deck drainage system, such as Trex RainEscape. Once installed, an under-deck drainage system creates a dry patio area on the ground level beneath the elevated deck.

With a dry under-deck area, you can create an outdoor living space that accommodates the installation of amenities covered by an underdeck ceiling. The outdoor living possibilities are endless: hot tub room, outdoor kitchen and dining area, entertainment room, or children’s play space.

There are many different material options to choose from when designing an under-deck ceiling, commonly referred to as a soffit.

Soffit Material for your Under-Deck Ceiling

Soffits are made from a variety of materials. Homeowners often choose an aluminum or vinyl soffit because they are less costly and easy to install. However, there are a variety of options.

Let’s take a look at the benefits and challenges of each soffit option:

Under-Deck Soffit Material	Benefits	Challenges
Aluminum	Superior durability that will not rot, chip, crack or rust No repainting required Highest ventilation efficiency of any product Easy to clean and maintain Highly flexible and less rigid than vinyl Water and fire-resistant	May be more difficult to remove after installation Harder to cut than vinyl Need to watch for sharp edges during installation Some systems may require professional installation versus DIY Aluminum may scratch or dent more easily
Vinyl	Very low maintenance Resistant to insects Less expensive than most other options Very versatile – lots of choices in colors and textures Highly durable – will not rot or corrode over time Water repellant Can withstand most weather conditions	Not as easy to install as aluminum Mold can form in damp areas Prolonged exposure to sunlight or extreme cold can cause it to become brittle which allows water to penetrate it Tends to look old after a few years Requires annual power washing Dents very easily The color can fade over time
Wood	More aesthetically appealing Natural material Environmentally-friendly and biodegradable Available in different wood types Can be painted to match any color	Less durable than other options Not water-resistant which causes rot, decay, warping, and splitting More expensive than other options High maintenance It takes more time to install Requires installing vents for air circulation
Hardboard	Strong Highly durable More affordable than wood Has the natural appearance of wood and stucco Available in different textures and colors Less maintenance than wood	Requires painting and staining although pre-painted options are available Susceptible to insect infestation Combustible Can crack over time Requires more maintenance than wood
Fiber Cement	Can be made to look like many other types of materials such as vinyl or wood Available in different colors and textures Does not wear as quickly as natural soffits Resistant to insects Does not grow mold or mildew One of the most durable materials available — can withstand harsh weather It is non-flammable and will not catch on fire Easy installation	Requires more work to deliver and install, making the cost of installation higher than other materials Requires repainting Professional installation required – not a DIY project
Steel	Available in a variety of colors Extremely durable Low maintenance cost Long lifespan Does not absorb moisture or promote mold growth Insect-resistant Recyclable	Can dent from a high-impact event Subject to scratching Susceptible to rusting over time More expensive than other options More time consuming to install because it is thicker and heavier than other options

The top considerations for an under-deck ceiling are maintenance, durability, and looks. Choose the option that best suits your dream for creating the perfect outdoor living space for you and your family.
