Screened Porch and Covered Deck Central Iowa

A roof and screens turn a deck you use three months a year into one you use most of the year. Busy Builders builds screened porches and covered decks across Central Iowa, on footings set below the frost line.

What Is a Screened Porch or Covered Deck?

A covered deck adds a roof over an outdoor space. A screened porch adds walls of screen too, which is what actually keeps Iowa mosquitos out in July. Both are structural upgrades over a plain deck, because a roof means posts, beams, and footings sized to carry it.

If you want a fully conditioned room, that is a sunroom instead. See our full deck building service, compare it with sunroom additions, or read our breakdown of screened porch costs in West Des Moines, Clive, and Johnston.

About Us

Since 2020, Busy Builders has completed 1,285+ construction and remodeling projects across Central Iowa. We build home additions for families who need more space and want it done right the first time.

Every addition we build is designed to match the existing home’s structure, style, and systems so it feels like it was always there.

Our Mission

Honest pricing, a clear written plan, and no surprise charges on every home addition project we take on.

We tell you what the project actually requires before a single permit is filed, and we do not upsell scope the addition doesn’t need.

Our Vision

We want to be the registered general contractor that homeowners in Des Moines, West Des Moines, Ankeny, Waukee, Johnston, and Grimes call first when the house isn’t big enough anymore.

Why Add a Roof and Screens?

Iowa Bugs Lose

July on an open deck is a negotiation with mosquitos. Screens end that argument permanently.

More Months of Use

A roof means rain does not cancel dinner and afternoon sun does not drive everyone inside.

Furniture That Survives

Covered outdoor furniture lasts years longer than furniture that sits in Iowa weather uncovered.

Footings Built for Freeze-Thaw

42 inches down, every time. Footings set shallow are why some decks pitch and separate.

Looks Like It Was Always There

The roofline ties into the house so the porch reads as original construction from the yard.

Compare It With a Sunroom

If you want heating and cooling and year round use, a sunroom is the better fit. We will tell you which one matches your goal.

How We Build Your Screened Porch

Step #1

USE & ROOFLINE PLANNING

We start with how many months a year you want the space, then look at how a roof ties into your existing house. The roofline connection is what makes a covered porch look original instead of bolted on, and it drives the design.

Step #2

DESIGN & PERMITS

Covered structures carry more load than a plain deck, so posts, beams, and footings get sized for the roof. Then we pull the permit through your city. You will know the review timeline before we schedule the dig.

Step #3

FOOTINGS BELOW THE FROST LINE

Iowa’s frost line sits at 42 inches, and footings above that depth heave every freeze and thaw. We dig below it, every time. This is the single most common failure we see on decks built by someone else.

Step #4

FRAMING & DECK SURFACE

Posts, beams, and joists go up, then the decking surface goes down. Pressure treated, cedar, or composite depending on what you selected and how much maintenance you want to sign up for.

Step #5

ROOF & SCREEN INSTALL

The roof structure goes on and ties into your existing roofline with proper flashing. Then screen panels install, sized so you can actually see out rather than looking through a grid.

Step #6

FINISHES & WALKTHROUGH

Lighting, ceiling fan wiring by a licensed Iowa electrician, trim, and stairs finish the space. We walk it with you before handoff. Written warranty on workmanship (details provided in your contract).

Permits and Iowa Code for Covered Structures

Covered structures need a permit in every Central Iowa city, and adding a roof raises the structural requirements over a plain deck. Iowa’s frost line sits at 42 inches, and footings set above that depth will heave during freeze and thaw cycles. Railings are required on decks 30 inches or more above grade, at a minimum 36 inches tall with balusters no more than 4 inches apart. The Iowa Building Code is administered through DIAL. We are registered with Iowa DIAL and pull permits through your city, including deck building in Altoona.

Disclaimer: This page is for general information and is not project-specific advice. Cost figures are planning estimates that vary by scope, materials, site conditions, and current pricing. Permit requirements vary by city and jurisdiction; verify current requirements with your local building authority before starting any project. Structural changes require evaluation by a qualified professional. Manufacturer warranty terms are set by the manufacturer; verify current coverage and limitations directly with them before purchasing. No specific outcomes are guaranteed. Consult a registered contractor for guidance specific to your project.

FAQs About Screened Porches in Central Iowa

Deck construction runs $15 to $25 per square foot for pressure treated and $30 to $50 for mid-range composite, and a roof and screens add structure on top. High-end builds run $50 to $80 or more per square foot. Your written estimate sets the real number.

It depends on whether you want year round use. A screened porch is open air with bugs kept out and costs less. A four season sunroom is insulated, heated, and cooled and works in January. We price both so you can compare.

Yes. Covered structures need a permit in every Central Iowa city, and the roof raises structural requirements over a plain deck. We handle the permit and inspections through your city building department.

Below Iowa’s frost line, which sits at 42 inches. Footings set above that depth heave during freeze and thaw cycles, which pitches the structure and pulls it away from the house. We dig below it on every build.

Most deck projects run 1 to 3 weeks from footing dig to final walkthrough. Larger builds with multi-level layouts or a pergola run 3 to 4 weeks. Adding a roof and screens sits at the longer end of that range.

Composite handles freeze and thaw with less maintenance than wood, and pressure treated costs less up front but needs regular sealing. Cedar sits between them. We walk you through the tradeoffs and the real maintenance commitment for each.
