Screen in Your Deck for a Bug-Free Summer

You can make the most of your backyard by converting your deck to a screened-in porch, which turns mosquitoes, heat waves, and downpours into non-events. Plus, the thwack of a screen door is still the soundtrack for summer.

Converting won’t be easy — unless you’ve got top-notch handyman skills, you’ll have to hire a pro. And it won’t be cheap — converting a 14-foot-by-14-foot deck into a porch will cost $10,000-$12,000.

But it’s worth the time and money. Screened-in porches add value to your home. Reginald Carter, a Jacksonville, Fla., appraiser, says the return on investment is about 70% if you stay in your home for at least five years after installing the porch.

Screened-in porches also can help you sell your home faster. In Virginia, for instance, about 70% of buyers can’t live without screened-in porches, says Elaine VonCannon, a REALTOR® from Williamsburg, Va.

“It works for everybody who likes to sit outside,” says VonCannon.

Can Your Deck Become a Screened-In Porch?


The biggest structural difference between a deck and porch is the weight of the load that rests on its foundation, joists, and beams, says David Berryhill, owner of Archadeck of Chicagoland.

Most decks are relatively lightweight: A 14-foot-by-14-foot deck can rest safely if it’s attached to the house and supported by three concrete piers. A porch, however, is much heavier because it has a roof. 

To prepare your current deck for the additional load, you’ll have to:

  • Possibly add more posts and foundation piers ($500-$5,000). Check with your local building code authority. In some municipalities, building codes require a solid concrete foundation, which could cost up to $10,000 (and would eliminate most decks from consideration as porches).
  • Beef up joists and beams to support the additional roof load.
  • Remove railings if you want a floor-to-ceiling screened porch, which gives you an unobstructed view.
  • Bug-proof deck floors. To keep tiny critters from climbing into your new porch from below, attach a fine mesh screen or landscape paper to the underside of the floor. Or, replace the current floor with tongue-and-groove boards that fit so tightly bugs can’t climb through.

Pick the Right Roof

The right roof makes the difference between a porch that looks like it was always part of your house, and one that looks like an afterthought with no architectural rhyme or reason. Some tips:

  • Select a roof shape that’s compatible with your house’s roofline. A hip roof is strongest, a shed roof the most economical, and a gable roof lets in the most light.
  • In some cases, the new roof can be built over the existing one, but you’ll still have to flash the valley and rearrange the gutters and downspouts.
  • Use the same roofing material as your main roof.

The Skinny on Screens

Know thyself before you select screening for your porch. Do you have rambunctious pets that make strength a top priority? Is there a beautiful view you don’t want blocked by an obtrusive screen?

Here are some options:

Fiberglass (17 cent/sq. ft.): An inexpensive, lightweight screening in black or charcoal. It’s easy to install but tears easily, too, and has a tendency to stretch and look floppy. 

Aluminum (26 cents/sq. ft.): Stronger and more durable than fiberglass, and the least visible. On the downside, aluminum dents easily and can oxidize.

Vinyl-Coated Polyester (60 cents-$1.53 /sq. ft.): Used to make pet screens that are super strong — down, Rex, down — and ones that dissipate heat in hot climates.

Bronze ($1.10/sq. ft.): Strong, doesn’t easily oxidize in salt air along coasts, and develops a patina with age.

Monel (alloy of copper and nickel) and stainless steel ($2.25-$5/sq. ft.): Strong, and tear-, rust-, and corrosion-resistant.

Screened-In Porch Tips

  • Pre-made screen panels are easier to install and repair than rolls of screening, but you pay the price of $50-$75/running ft.
  • When planning your porch project, check local building codes for setback regulations and building specifications.
  • Don’t forget to add electrical outlets to your porch for lamps, ceiling fans, and phone chargers.
  • Porches block light and can make the inside of your house seem dark. You can cure that by installing a skylight in the room adjacent to the porch.
  • Building codes may require that you have a 3-foot-by-3-foot concrete landing outside the egress door to your porch.
