Yes, but ensuring the deck has a solid foundation with adequate footings is critical before building, as the weight of a sunroom will put significant pressure on the structure below. Even if your deck is properly constructed, it may not be able to handle the extra weight. While some basic, lightweight, prefabricated sunrooms can sit on a deck with a strong existing foundation without additional supports, in many cases, the foundation and joists will need reinforcement. It is always best to have a structural engineer perform an inspection to evaluate the deck's quality and structural integrity. A professional can help you decide if reinforcement is sufficient or if it's better to tear down the deck and start over.

The least expensive way to enclose a porch is with screens. These protect the room by preventing insects from entering and, if you live in a warm climate, provide excellent airflow during hot summer months. Screens cost far less than any other alternative, so if you are against getting permits, spending too much, or enclosing your porch in walls or glass, screens are the best choice. 

With proper maintenance, the average life span of a screened-in porch is six to eight years for the screens themselves, but the foundation and structure can last for 50 to 100 years. To keep your screened-in porch in good shape, clean your porch screens regularly, patch holes, re-seal the wood as needed, and address any foundational issues right away.

A prefab sunroom will last for between 10 and 20 years in most cases, although you could get up to 50 years out of a high-quality prefab sunroom. In addition to material quality, your prefab sunroom’s lifespan will depend on the foundation type and the climate in your area. Extreme weather and expansive soil can decrease the expected life.
