Can You Screen In an Existing Porch?

Yes; most existing covered porches and patios in Michigan can be screened in, usually without tearing anything down. If your porch already has a finished floor, a roof, and support posts, screens can go straight into the existing openings.

Key Takeaways

• Yes, most existing covered porches can be screened in. If your porch already has a finished floor, a roof or solid cover, and support posts, an installer can add screens without a rebuild.
• Cost runs in ranges, not fixed prices. Plan on roughly $10–$25 per square foot, with a typical professional screen-in landing around $2,000–$5,000 depending on size, materials, and site conditions. DIY materials cost less but trade time and finish quality.
• Permits vary by Michigan municipality. Adding screens to an existing roofed structure is often a minor alteration, but always check with your local building department—building a new roof to mount screens usually does require a permit.
• Screen type matters most. Traditional fixed panels are cheapest; motorized retractable screens like MagnaTrack by Progressive Screens (https://skyviewusa.com/magnatrack-screens/) roll out of sight and last longer in Michigan weather.
• No roof? You have options. An open patio or deck needs overhead cover first—often a StruXure pergola (https://skyviewusa.com/struxure-pergolas/) with a solid roof—before screens can go in.

Your porch works fine in May. Then the mosquitoes arrive, the afternoon sun turns one side into a heat trap, and a space you paid for sitting is empty for months.

So you start looking into screens, and the question is always the same: can you screen in an existing porch, or does that mean tearing it down? The good news? Most structures already qualify.

Here’s what you need to know about screened porch requirements, how permits work in Michigan, and why the type of screen matters more than most homeowners expect. Stick around for all the details.

Can You Screen In an Existing Porch?

Yes. Most existing porches, patios, and covered decks can be screened in without a rebuild, as long as the structure already has a floor, a roof, and support posts.

That describes a lot of Michigan homes. 

An installer measures the openings between your posts and builds screens to those dimensions. The structure stays where it is; only the openings change.

What Does Your Porch Need to Have Before It Can Be Screened In?

Three things decide whether you can screen in a patio or deck as it stands today:

• A finished floor: A concrete slab, deck boards, or pavers that sit level and hold weight without flex.
• Overhead cover: A porch roof, a solid patio cover, or a louvered pergola with a closed roof. The screen housing mounts to its underside.
• Support posts: Vertical posts or columns on both sides of each opening, which give the side tracks something to anchor into.

An open deck with no cover needs a roof built first, which turns a screening project into a construction project and changes the permit conversation.

How Much Does It Cost to Screen In a Porch?

Most homeowners spend about $10–$25 per square foot to screen in an existing porch, which works out to roughly $2,000–$5,000 for a typical professional installation. Costs vary by the size of your openings, the screen material you choose, and site conditions like post height and spacing, so treat these as ranges rather than a quote. DIY materials cost less up front but trade the savings for your own labor and a shorter-lived result. For a full worked example, see what a 20×20 screened-in porch costs.

What drives the price:

• Screen material: Standard fiberglass mesh sits at the low end; heavier aluminum, pet-resistant, and solar-blocking meshes cost more.
• Openings and size: More openings, wider spans, and taller walls mean more material and labor.
• System type: Traditional fixed panels are the cheapest; motorized retractable screens carry a higher up-front cost for the convenience and longevity.
• Extras: Screen doors, upgraded framing, and paint-matched housings add to the total.

DIY vs. Professional Porch Screening

DIY screening works for small, simple porches and tight budgets; professional installation makes sense for large openings, motorized systems, and a finish that lasts. A DIY screen kit keeps material costs down, but square corners, taut mesh, and weather-tight tracks are harder than they look, and a fixed panel that sags or tears within a season erases the savings.

Choose DIY when your openings are small and standard, you want fixed panels, and you’re comfortable with careful measuring and framing. Choose a professional when your spans are wide or tall, you want a motorized system like MagnaTrack motorized screens, or you want a manufacturer-backed warranty and a clean, no-callback install.

Porch Screen Options: Materials, Doors, and Motorized Systems

Your main porch screen options are the mesh material, whether you add a screen door, and whether the screens are fixed or motorized. Each choice trades cost against durability, view, and comfort.

Screen mesh:

• Fiberglass: the standard—affordable, flexible, and easy to replace.
• Aluminum: stronger and longer-lasting, holds shape without sagging, costs more.
• Pet-resistant: a heavy-duty weave that stands up to claws and roughhousing.
• Solar: blocks a share of heat and glare for hot, sun-exposed porches.

Screen doors: A framed or retractable screen door keeps the enclosure usable without leaving a gap bugs can exploit.

Motorized screens: Retractable systems roll out of sight when you don’t need them; see the comparison below.

Screen-In Option	How It Works	Typical Cost	Best For
Traditional screen	Fixed framed mesh panels set permanently into each opening	Lowest—roughly $10–$15/sq ft installed	Small porches and tight budgets
Motorized retractable (MagnaTrack)	Mesh rolls down a magnetic side track on demand and retracts into a hidden housing	Higher up-front; varies by size and number of openings	Michigan weather, wide or tall openings, and a clean view
Three-season / sunroom conversion	Screens plus glass or panel systems enclose the space for use in more months	Highest—priced as a full enclosure	Year-round-leaning use and added finished space

Do You Need a Permit to Screen In an Existing Porch in Michigan?

Usually not, though your city or county has the final say. Adding screens to a structure that already has a roof and posts counts as a minor alteration in most places, so a permit to screen in a porch often isn’t required. Building a new structure to mount those screens on usually does require one.

Michigan rules vary by community. Detroit, Oakland County, and Livingston County each set their own thresholds for what triggers a permit. Call your local building department before you finalize anything, or have your installer confirm it. 

What’s the Difference Between Traditional Porch Screens and Motorized Screens?

Traditional screens sit fixed in place. Framed panels go into the openings and stay put year-round. They are the cheapest way to screen in a porch, and they do keep the bugs out. They also hide your open view permanently, sag as the mesh stretches, and tear when a branch catches them.

Motorized porch screens lower when you want them and retract completely out of sight when you don’t. Rolled up, the mesh sits inside a housing above the opening, protected from sun, wind, and snow, which is a big reason retractable porch screens outlast fixed panels. That’s especially true when you’re in an area like Michigan, where one week brings mosquitoes, and the next brings a cold front off the lakes.

How Does a Motorized Screen System Work?

A motor inside the housing raises and lowers the mesh along a track on each side of the opening. 

The MagnaTrack system uses a patented magnetic track built around rare-earth magnets that hold the screen edge under constant tension. There are no zippers to jam and no gaps along the sides on a windy day. Think of it like a tape measure. The blade stays flat and taut the whole time it is out, then rolls back into its case.

Size is the other advantage. MagnaTrack screens are custom built to fit almost any existing opening, up to 30 ft wide and 20 ft tall, so most porches get screened without framing changes. You run them from a handheld remote, a wall switch, or your phone. You can also automate them to close on a schedule or when a weather sensor picks up wind or rain.

How Long Does It Take to Screen In a Porch?

Most porch screen-ins take one to three days on site once materials are ready. A straightforward fixed-panel job on a standard porch can wrap in a day; motorized systems and larger openings run longer because of precise track mounting and wiring. The bigger part of the timeline is usually lead time—measuring, custom fabrication, and any permit sign-off—which can add a few weeks before install day.

Can You Screen In a Patio or Deck With No Roof?

Not as-is—an open patio or deck needs overhead cover before it can be screened in. Screens mount to a roof or solid cover and anchor into side posts, so a bare slab or open deck has nothing to attach to at the top.

The common fix is to add structure first. A StruXure pergola with a solid, louvered roof gives you the overhead cover and posts that motorized MagnaTrack motorized screens need, turning an exposed patio into a screened, shaded outdoor room. Once the cover is in place, the screening step works the same as it would on any covered porch.

Three-Season and Beyond: Upgrading a Screened Porch

If you want the space in more than the warm months, a screened porch can step up to a three-season or year-round room. Screens keep bugs out in summer; adding glass or panel systems keeps wind and cold out in spring and fall.

Paths to consider:

• Glass enclosures: glass enclosure systems slide or swing open in summer and close tight when the temperature drops.
• Sunrooms: a LivingSpace sunroom converts the footprint into fully finished, insulated space.
• Winter prep: if you’re keeping it seasonal, our guide to winterizing a screened porch helps it survive Michigan winters.

Does Screening In a Porch Add Value to Your Home?

Short answer: Yes, in two ways.

• The first is usable space. A screened porch in Michigan gives you a room you actually sit in through July and September, months when the open version sits empty.
• The second is resale appeal. A covered, screened area reads as finished space, and buyers walking through in July notice a porch they could sit on that evening.

Frequently Asked Questions

Can You Screen In an Existing Porch?

Yes. Most existing covered porches, patios, and decks can be screened in without a rebuild, as long as they already have a finished floor, a roof or solid cover, and support posts on each side of the openings.

How Do You Screen In an Existing Porch?

An installer measures the openings between your existing posts, then builds screens—fixed panels or motorized retractable systems—to those exact dimensions and anchors them to the roof underside and side posts. The structure stays put; only the openings change.

How Much Does It Cost to Screen In a Porch in Michigan?

Plan on roughly $10–$25 per square foot, or about $2,000–$5,000 for a typical professional job. The exact figure depends on size, mesh material, and whether you choose fixed or motorized screens, so treat it as a range rather than a fixed price.

Do You Need a Permit to Screen In a Porch in Michigan?

It varies by municipality. Adding screens to a structure that already has a roof and posts is often treated as a minor alteration that needs no permit, but building a new roof or structure to mount screens usually does. Always check with your local building department first.

Should You Screen In a Porch DIY or Hire a Professional?

DIY suits small, standard openings and fixed panels on a tight budget. Hire a professional for wide or tall spans, motorized systems, and a weather-tight finish that lasts through Michigan seasons.

What Screen Options Are There for a Porch?

Common choices are fiberglass (standard), aluminum (stronger), pet-resistant, and solar mesh, plus fixed panels versus motorized retractable screens, and an optional screen door for access.

How Long Does It Take to Screen In a Porch?

On-site work usually takes one to three days, with fixed panels faster than motorized systems. Custom fabrication and any permit review can add a few weeks of lead time before installation day.
