Planning a Covered Patio That Works in Dallas Heat

A covered patio can add a room to your house without adding a single wall, but only if you'll actually sit out there. In Dallas, that comes down to how you handle the sun and the heat. Get those right and the space gets used from March through November. Get them wrong and it becomes a place to store the grill.

Start with orientation and the west sun

Before you think about materials, notice where the sun is. A patio facing west takes the hardest light in the hottest part of the day, and in a Dallas summer, late afternoon is when most people want to be outside. A south-facing cover gets high overhead sun that a roof handles well. An east-facing spot is shaded by midafternoon, which is often the most comfortable choice.

If your best spot faces west, plan for it. Options include a deeper roof overhang, a screen or slatted wall on the west side, nearby trees, or sun shades that can be dropped in the late afternoon. Try standing where the patio would be at 4 PM on a hot day. It tells you more than a drawing will.

Covered patio or pergola

A solid-roof covered patio blocks sun and rain, and it can be tied into the house roof or built as a freestanding structure. A pergola, with open rafters or slats, filters light and gives a pleasant dappled shade, but it doesn't keep rain off your furniture and it lets more heat through. Many homeowners who start with a pergola in mind find that a solid cover fits Texas weather better, and some choose a hybrid with a solid section over the seating area and open rafters beyond it.

Fans that can handle the outdoors

Moving air makes a hot patio feel many degrees cooler. Use ceiling fans rated for outdoor use, labeled damp-rated for covered spaces or wet-rated for ones that can get rained on directly. An indoor fan will rust, warp and wobble. Plan the electrical early, so the fan box is properly supported by framing, not just hung off a ceiling board, and so there's power for lighting and outlets before the ceiling is closed in.

Details that decide how long it lasts

• Post bases that lift the wood off the slab: metal standoff bases keep the bottom of each post from sitting in water and wicking it up.
• Flashing where the cover meets the house: this is the most common leak point. Proper flashing is tucked beneath the siding or wall covering and lapped over the cover, so water runs outward, not behind the wall.
• Drainage and slope: the patio surface should fall away from the house, and the cover's roof should shed water to a place that won't flood the slab or the neighbor's side yard.
• Gutters or a drip line along the roof edge, so runoff doesn't erode the soil or splash back on the posts.
• Fasteners and connectors rated for outdoor use, so they don't streak and fail.

Materials that handle sun

Dallas sun is hard on everything outdoors. Cedar is a popular choice for posts, beams and tongue-and-groove ceilings because it resists rot and insects well, and it looks warm. Left bare, it fades to a silvery gray over time. If you want it to stay golden, plan on regular sealing or staining, usually every few years depending on exposure.

Painted surfaces look crisp and can match the house, but they need upkeep. West and south faces will chalk and peel sooner than shaded ones, so expect to repaint on a schedule and prime properly the first time. Whatever you choose, ask your contractor how it will look in five years, not just on the day it's finished, and what upkeep you're signing up for.

Think about how you'll use it

A patio for morning coffee has different needs than one for evening dinners with a crowd. Decide where the grill goes, how much clearance people need to walk around the table, where lights and outlets belong, and whether you want the space to feel connected to the kitchen. Sketch furniture at real size on the slab with chalk or painter's tape before anything gets built. It's the cheapest design review you'll ever do.
