A screened porch is one of the most-requested projects in the Triangle, and the price range is wide because "screened porch" can mean anything from screening in an existing covered porch to building a roofed room off the back of the house. Here's how the options compare.
Price ladder
HomeGuide's screened porch guide (February 11, 2026) and deck guide (February 10, 2026) give these national ranges:
| Project | National range |
|---|---|
| Screen in an existing covered porch | $2,000 – $5,000 ($10 – $25 per sq ft) |
| Build a new screened-in porch | $10,000 – $35,000 |
| New porch with base and roof frame | $40 – $150 per sq ft |
| New open deck | $25 – $50 per sq ft |
| 12×12 open deck | $3,600 – $7,200 |
| Sunroom | $100 – $350 per sq ft |
Compare the per-square-foot rows: a sunroom's conditioned, glazed walls put it in a different price class from a screened room. HomeGuide's estimate for a permit for a new screened porch is $200 to $500.
What drives the price on Triangle lots
Height off the ground. Many Triangle backyards slope. A porch that's at grade on one side may stand well above the yard on the other, requiring taller posts, more bracing and longer stairs.
The roof. Tying a new roof into an existing one is the biggest structural cost. A shed roof under existing eaves is usually simplest; a gable roof that matches the house costs more.
Foundation. Footings sized for the roof load, in clay soils that hold water.
Floor. Treated wood, composite, or a concrete slab with a knee wall.
Ceiling and electrical. Tongue-and-groove or beadboard ceilings, ceiling fans, lights and outlets.
Screen system. Basic fiberglass screen and wood stops cost less than aluminum screen framing systems or fine-mesh "no-see-um" screens.
Access. A new door from the house, sometimes requiring a header in a load-bearing wall.
Permits and approvals
A new screened porch or a roof over a deck is load-bearing work, so it needs a building permit in North Carolina. Some towns are stricter on decks; Cary requires a permit for every deck. See Cary decks and porches. In HOA neighborhoods, which are common in Holly Springs and other suburbs, architectural approval comes first.
Choosing between options
- Already have a covered porch? Screening it is by far the cheapest upgrade.
- Have a sound deck? Adding a roof and screens to part of it can work if the framing and footings can take the load. An engineer or experienced builder should check.
- Starting from scratch? A new screened porch with an adjoining open deck or patio for grilling is a popular combination.
- Want year-round use? A sunroom or addition costs much more but adds conditioned space.
How you'll use it changes the budget
Think through the seasons before you set a budget. A screened porch used mostly on summer evenings needs good fans and lighting more than anything else. One you hope to use in March and November benefits from a solid wall on the windward side, a fireplace or a heater rated for outdoor use, and vinyl or glass panels that can replace screens in winter, which moves it toward three-season-room pricing. If you plan to eat out there, put the porch next to the kitchen and add an outlet or two near the table. If it's a place for kids and dogs, choose a durable floor and pet-resistant screen low on the walls.
Where the money is well spent
- Fans and wiring. A damp-rated ceiling fan is what makes a porch usable in August. Running the wiring during construction is cheap compared with retrofitting it.
- The roof tie-in. A clean tie-in that matches the house protects the existing roof and looks original.
- Footings and framing. You won't see them, but they decide whether the porch stays level.
Budget extras people forget
- gutters and downspouts for the new roof;
- landscape repair after construction;
- outdoor furniture sized for the space;
- staining or painting wood;
- a door with a closer, and pet-resistant screen near the bottom if you have dogs.
Getting comparable bids
Ask each builder to state porch dimensions, roof style and tie-in, footing size and count, floor and ceiling materials, screen system, electrical scope, door, permit fee and HOA paperwork responsibility.

Frequently asked questions
Is screening a porch a DIY job?
Screening an existing porch with simple wood stops is a common DIY project. Structural work and roofs aren't.
Does a screened porch add value?
It adds usable outdoor space that many Triangle buyers want, though resale value depends on quality and the neighborhood.
How long does a new screened porch take to build?
Often a few weeks of construction, plus time for design, HOA approval and permits.
