The short version
Two decisions, not one
Every patio cover is really two choices. What the frame is made of, which drives maintenance and how long it lasts. And what the roof is made of, which drives how hot it gets underneath and how loud it is when it rains. People shop the first one and feel the second one every day.
The frame
Aluminum or wood
- Extruded aluminum. Does not rot, warp, or need refinishing, and it spans further with fewer posts. Costs more up front and reads more modern. The default for louvered systems.
- Cedar or treated pine. Warmer look, easier to match existing trim and stain, lower material cost. Needs resealing every two to four years in this sun, and post bases need proper standoffs so they are not sitting in water.
- Steel. Strongest spans and the most slender posts. Less common residentially, more expensive, and it has to be finished properly or it will show rust at every cut and weld.
The roof
What goes over your head
- Insulated panel. Foam core between two metal skins. Coolest underneath, quietest in rain, gives you a finished ceiling. The upgrade most owners say was worth it.
- Shingled roof on framing. Matches your house because it is the same roof. Best looking option and the most expensive, since it is real framing, decking, and roofing.
- Bare aluminum or metal pan. Cheapest permanent roof. Sheds rain fine, radiates heat downward, and is loud in a storm. Fine over a walkway, less pleasant over a dining table.
- Polycarbonate panels. Lets light through, so the room behind stays bright. Also lets heat through, which in July is the problem, not the feature.
- Adjustable louvers. A roof you can open. Covered in detail on the louvered roof page.
One thing worth thinking about before you pick: a solid roof against the back of the house will darken the rooms behind it. If that patio sits outside a kitchen or a living room, ask about a skylight panel, a lighter ceiling finish, or louvers you can open in winter.
Good to know
Common material questions
Does an insulated panel cover really make a difference?
Under a Texas afternoon, yes, and it is the upgrade people notice most. A bare aluminum or metal roof radiates the heat it absorbs straight down onto the patio. An insulated panel puts foam between you and that heat, and it cuts rain noise at the same time. It also gives you a finished ceiling instead of looking up at framing.
How much maintenance does a wood cover need here?
More than most people plan for. North Texas sun and the wet to bone dry swing are hard on a finish, so expect to reseal or restain every two to four years depending on exposure and product. Skip it and you get graying, checking, and eventually rot at the post bases and any spot that stays damp.
What roof style should I match to my house?
The two common choices are a flat or low slope roof that tucks under the existing eave, and a gable that continues your roofline. Tucking under is cheaper and keeps the structure low, which matters if your eave is not high. A gable costs more, opens up the ceiling, and usually looks like it came with the house, especially if it is shingled to match.
