Access the size and area of the rooftop patio to get an idea of what you want to do with the space. Use the patio as a sitting or dining area if the space is limited, or section it off to create separate sitting and dining spaces.
Cover the patio floor with treated wood decking materials to create a natural appearance for the outdoor space. If you're on a budget, cover the existing flooring with an outdoor rug to complement your new decor.
Assemble the outdoor furniture and place it in the desired locations. For seating areas, use outdoor loveseats or chairs that complement your personal style and place matching tables around the seating for convenience. Keep the space cohesive by adding an outdoor dining set in the same materials and place in the appropriate place.
Incorporate colors and patterns into the patio design by adding throw pillows to the seating areas or seat covers to the dining furniture.
Place heat-tolerant plants around the deck to give it a fresh look and incorporate a garden into the space. Since the patio is exposed to full sun, plants need to be hardy and tolerate heat. Appropriate vegetables for a patio garden include peppers and tomatoes. Plants should be grown in a light-colored planter to avoid overheating the roots.
String up twinkling lights or tiki torches to provide soft lighting when you're on the patio at night. Place candles around on the tables to increase lighting when you're sitting around the dining table or sofas.
