Cost To Build A Covered Patio By Location

Most patios are located beside the home. This makes them easily accessible and still leaves plenty of space for the rest of the yard and landscaping. But patios can be located elsewhere on the property, particularly if you want them located beside another feature like a pool, tennis court, or fountain.

The cover can also have different positions. If the patio is located beside the home, the cover can be either attached to the home, extending out over it, or it can be freestanding. When the patio is moved away from the home, the structure must be freestanding, limiting your choices for the cover. Both attached and freestanding covered patios have a wide range of costs because patios and covers come in many sizes and materials.

Common Types Of Wood Used To Build A Roof Over A Deck

It involves beams and rafters, and because the deck is an exposed place, it is wise to invest in building materials to withstand different harsh weather conditions. The sizes of the beams and rafters to use are 6×6, 6×2, 8×2, 10×2.

Here are some wood beams and rafters materials to choose from:

Cedar Wood

Cedar is a popular choice because it is resistant to rot and insects. It is also readily available and not heavy. It is the best material for an already existing deck as it will not exert too much pressure on the existing wooden board.

But the trick to brighten its surface is to apply a sanding sealer and clear varnish after it has been installed. The price of cedar is $3-$5 per square foot.


Compared to cedar, redwood is a better material but costs more. They cost between $6-$8 per square feet depending on the region and availability.

But redwood is hard to find in the eastern states compared to its availability in the western states.


Indigenous eucalyptus is among the hardwoods found in tropical areas. Mature trees with more than twenty years to their belt can last fifty years and beyond when treated with oil-based products.


Pine is the most common building material because the wood is inexpensive, light, and straight. However, pine is a softer wood and is not resistant to insects. Therefore, its best not to leave pine exposed without painting is to seal it from moisture.

Do You Need A Permit To Install A Pergola

In many cases, a permit will not be required, but depending on the area and type of pergola, consult with your local council for the required permits for construction. Two main permits the planning permit and construction permits are required and the council charges a fee for issuing them. Your licensed builder should be able to give you more information about the necessary permits.

Pressure Treated Deck Cost

On average, a pressure treated wood deck costs $6 per square foot for materials, or between $12 and $18 per square foot installed. Pressure-treated wood is used on almost 75% of all decks in the US today. Chemically treated under pressure, it is fabricated to make the wood more resistant to mold, insects, and rot.


  • Pressure-treated wood is generally made from low-grade fir or pine that tends to warp and crack over the long haul, and that creates the ongoing need for a rigid maintenance schedule.
  • When pressure-treated wood meets water, any metal used in the construction of the deck like aluminum flashing, galvanized nails and screws, fasteners, joists, and deck hangers will begin to corrode. If left without being repaired will cause dangerous structural instability in your deck.
  • If you elect to have pressure-treated wood used in your deck, you are signing up for a regular maintenance schedule that includes sanding, sealing, and staining.

A Thumbtack pro and experienced carpenter in Snellville, Georgia, typically charges between $20$50 per square foot for materials and labor to build a pergola, depending on the complexity of the build.

For example, they recently built a 480-square-foot, pressure-treated pine deck topped with an 8×10 pergola. It included a custom roof and handrails on one side and the total cost was $6,500. That price included:

  • Materials cost: $3,750, including wood, concrete, posts, fasteners, and screws
  • Labor cost: $2,750, which included ground prep and construction
  • Design work: Six hours in total
  • 42 hours total of labor: Three-person crew, for two days

However, this Georgia-based pro said that a standard pergola on a traditional deck generally costs about $25 per square foot.

And it can be even cheaper to install a DIY pergola kit. A Thumbtack pro in Costa Mesa, CA offers 2-day pergola and gazebo kit assembly for the flat rate of $600.

Glass Patio Cover Cost

The average cost of a glass patio cover is between $25 and $45 a square foot installed. These covers give a very contemporary appearance. They offer a solid cover, which keeps off the rain. However, unless the glass is tinted or shaded somehow, it does not offer much protection from the sun. Glass roofs also heat up the area below very quickly, so they work better in cooler climates. Several different glass types can be used this way, but using panels is the most common method.

Cost To Install A Roof On Your Pergola

When you look at the basic pergola design, youll notice that its an open-roofed structure. This means that it generally doesnt give you much protection from the elements or shade by itself. Growing plants over the top of the structure or getting a shade cloth are two popular ways to give it a temporary roof. However, its possible to give it a permanent roof too.

Youll notice that some companies do offer kits that come with slats that you space much closer together to give you up to 90% shade. Some offer UV-material roofs that block out harmful UV rays. You can add a complete, solid roof to your pergola, but you should be prepared to pay for it. Depending on the size, design, and material you want, adding a roof to your structure can increase your cost to build a pergola by as much as $15,000 for a larger structure.

How To Determine The Size Of Your Pergola:

How to measure the size of your pergola: The rafters and top slats typically have a one foot overhang past the posts. The total coverage of the pergola is calculated based on the total length of the rafters and top slats including the one foot overhang. So for example lets say that you have a patio that measures 10×10. If we place the posts at the edge of the patio and account for a one foot overhang on each side you will end up with total coverage being 12×12. So a 100 square foot patio will often have a pergola that measures 144 square feet. This will maximize the ground space of the patio by placing the posts as far out as they can go, and it will also maximize the shade coverage of the pergola itself.

A pergola may seem like a simple DIY project you can knock together over the weekend, but it’s worth getting a professional involved if you want safe, secure results that last for years. Ask your contractor about the best style, size, design, building materials, and any custom extras they specialize in to ensure you get the best overall look for your home improvement project at the best price.

The right pergola can extend your outdoor space, protect your garden and prized plants, serve as a centerpiece for your BBQ or landscaping project, or simply add resale value to your home.

Typical Price Range Of Pergolas

The cost of constructing a pergola can range anywhere from $2,000 to $6,000, or $10 to $60 per square foot, depending on the size, materials selected, and whether you hire a pro or DIY, says Bailey Carson, home care expert at Angi.

“For a simple pergola, hiring a pro will typically cost about $500 to $1,000 more than DIY, to account for labor,” says Carson. “Costs can go up depending on size, complexity, or level of customization.”

The home services website Thumbtack, meanwhile, estimates that the cost of materials and labor to install a 10×10-foot pergola is around $3,600. But Thumbtack adds that prices can range from as little as $1,000 for a small prefab vinyl or PVC kit to $9,000 for the design and installation of sprawling custom patio covers and structures made from high-end materials such as teak wood. The final overall cost, however, depends highly on the finish of your pergola structure, its size, and its function.

Additional Considerations And Costs

  • Sealing. If you use a wood that is not cedar or redwood, you need to stain or seal the pergola. While cedar and redwood are resistant to rot and insects, other woods are not and must be protected.
  • Structural work. If you install your pergola on an old deck or uneven ground, you have additional labor costs and potentially more structural costs. This is because the pergola must be evenly supported, and the ground or structure below must support its weight.
  • Discount. In some areas, you could receive a discount on labor costs by building your pergola off-season. As long as the weather is conducive to the project, some contractors may offer a lower rate when they have fewer clients.
  • Foundation. Not all pergolas require footers or a foundation. If you choose to pour a foundation for your pergola, you have much higher costs.
  • Design. Ensure your pergola matches your propertys design and style. It is also important to consider the size because some oversized structures may restrict the surrounding area.
  • Permits. While many places do not require permits for this project, some do. To find out more, check with your municipality.

Metal roofing now also comes in various attractive shingle styles as well as standing seam and corrugated sheets. There are still other options for roof coverings, such as clear polycarbonate plastic sheeting, skylights, and a durable canvas-type material.

How To Build A Diy Pergola

There are a few different ways to build a pergola. A couple of the most popular is building from a kit, gathering the materials needed, and building the entire structure from scratch.

A pergola is a somewhat simple structure however, it is essential to note that it is a very labor-intensive process. Lets start with the basics.

A basic pergola is usually 8 feet by 16 feet, and you build the support structure using six posts. The top of the pergola usually consists of 1-by-3s, which is great for hanging decorations or plants.

One of the most challenging parts of building a pergola is digging the holes for the support posts from my experience. Although you can do this manually, it is very labor-intensive.

Therefore, I recommend using an earth auger to make the process easier and less time-consuming. However, if the soil is soft, it may be more effective to dig the holes manually. It really depends on the condition of your soil at the time youll be digging.

Finally, I would recommend checking with your local municipality, as building a pergola may require a permit, especially in densely populated residential areas.

In the past, I had to apply for an outdoor detached accessory structure permit however, you should consult your local code office, as these regulations may differ by area.
