Installing a patio or deck roof costs an average of $21,000. Most homeowners pay between $14,000 and $31,000, depending on the square footage, type of roof, and material used.
While there are many factors to consider, building a patio or deck roof costs $21,000, on average. This is a cost worth swallowing once you consider the relaxing afternoons and protection from the rain you get from installing one. However, every situation is different, and prices range significantly from $3,000 and $55,000 depending on the size, type of roof, and material used.
Dig into the details of what makes up the cost of a deck or patio roof install. The price is high—but there are ways you can save as well.
Deck or Patio Roof Cost Factors
The cost to add a roof over a deck or patio fluctuates based on key cost factors like size, material, and roof style.
Type of Deck or Patio Roof
What style of roof you choose will depend on certain factors, namely the style of your main roof, your budget, and the desired purpose of your deck or patio roof. For those looking for only rain protection, an awning or lean-to fulfills that purpose and at a lower cost. Gabled roofs are the most expensive, but many consider them the most aesthetic (plus, they tend to last a long time). Ultimately, the type of roof you choose is up to you.
| Patio Roof Type | Average Cost to Install |
|---|---|
| Gable | $13,000–$30,000 |
| Pergola | $4,000–$15,000 |
| Louvered | $10,000–$25,000 |
| Lean-to | $6,000–$11,000 |
| Awning | $1,500–$7,000 |
Deck or Patio Roofing Material
After deciding which type of roof you’re installing, you need to choose the roofing material. Most homeowners try to match the deck or patio roofing with the rest of their house. After all, a house with a metal roof might look a bit strange with an asphalt deck or patio roof.
If you’re looking for more of a greenhouse effect, consider fiberglass roofing, as it’s the only material that allows light penetration. Many believe the diffused lighting effect is a pleasant way to protect from UV and rain. It’s also the least expensive option.
| Roof Material | Cost Per sq. ft. |
|---|---|
| Fiberglass | $2–$4 |
| Asphalt shingles | $2–$5 |
| Clay tile | $5–$13 |
| Metal | $6–$38 |
| Slate | $9–$25 |
| Wood shakes | $6–$16 |
Size of Deck or Patio Roof
Increased roof size leads to higher installation costs. This is because bigger roofs require extra support, installation time, insulation, and other materials.
| Patio Size in Square Feet | Average Roof Cost |
|---|---|
| 100 | $3,000–$11,000 |
| 150 | $4,500–$16,500 |
| 200 | $6,000–$22,000 |
| 250 | $7,500–$27,500 |
| 300 | $9,000–$33,000 |
| 400 | $12,000–$44,000 |
| 500 | $15,000–$55,000 |
Roofing Professional Costs
Expect to pay a roofing professional a project-based fee for this work. A common markup is 20% to 30% of the total project cost and often includes sourcing permits, laying out plans, and completing the work. Hourly rates vary, but the labor cost to build a roof over a deck ranges from $30 to $90 per hour per worker.
Electrician Costs
If you have plans to install lighting, a fan, a TV, or a sound system, you should hire an electrician. Electricians charge hourly rates from $50 to $130 per hour. Electricians can make more money charging hourly than project-based, so it's not unusual to be quoted in hours versus a total project fee.
General Contractor
General contractors charge about the same as roofing professionals—$30 to $90 per hour per worker or around 25% of the total project cost. The vast majority of them will do a great job, but if the costs are similar, it's better to go with a dedicated roofing professional.
Additional Cost Factors
Demolition and Prep
The professional you hire will plan for structural support. Unlike some other jobs, there shouldn’t be much demolition work and the prep work (outside of constructing load-bearing beams or roof frames) will likely be limited to cleaning work.
Permits
Installing a deck or patio roof will require building permits in almost every instance. Homeowners can expect to pay between $200 and $1,400 for a permit. Many people don’t have experience submitting plans for permit approval, so lean on the professional you hire to help.
Repairs
Over time, you might need to carry out roof repairs. Repairs can range from $75 up to around $1,000 or more. The total cost will depend on the type of damage, how extensive it is, and the roof material you have over your patio.
DIY Installing a Deck or Patio Roof vs. Hiring a Pro
You can build your deck or patio roof yourself to save on labor costs. The average cost to DIY a simple roof is $1,250 to $1,350. However, it’s important to note that this type of DIY project is quite involved and involves seriously heavy tools and materials, often at dangerous heights.
For most homeowners, regardless of roof type or material chosen and who want a roof that matches the main home, it’s best to hire a professional roofing company near you. They’ll have the experience necessary to pour solid footings, ensure your roof is structurally sound, and even aesthetically tie the roof into your home.
Deck or Patio Roof Replacement vs. Repair
Let’s assume you already have a deck or patio roof installed. Some damage appears and you’re wondering whether to replace the roof or repair it. There are two factors that determine the answer:
Will the repair cost as much or more than 50% of a replacement?
Does the repair affect the structural components of the roof?
If the answer is yes to either of these questions, you should replace the roof. You can take chances on certain repairs—structural ones, especially ones that literally hold a roof over your head, are not repairs you should DIY or put off until later.
Cost of Common Patio and Deck Roof Add-Ons
If you’re looking to create the ultimate outdoor entertainment area, consider some of the following add-ons:
Ceiling fans: $250–$600
Outdoor sound system: $300–$2,600
Outdoor TV: $150–$2,200
Solar shades: $100–$300
Outdoor kitchen: $5,000–$26,000
Tips to Save Money While Installing a Deck or Patio Roof
Instead of negotiating labor costs, focus on the cost of the materials. Ensuring you get the best material at the best price comes down to working a few angles. Some things you can do to lower the cost of a deck or patio roof are:
Choose an affordable material: Roofing materials range from around $2 up to $38 per square foot.
Limit the roof coverage: Covering your entire patio with a roof isn’t always necessary, and you could save money by just covering a small seating area allowing for both sun and shade.
Use recycled materials.
Consider extras carefully: Add-ons like outdoor kitchens and skylights can quickly bump up your installation costs. Consider avoiding nice-to-haves to keep your upfront costs as low as possible.
Keep the design simple: Simple roof designs with few bump-outs and just a single ridge will reduce the materials needed, as well as the labor required for the installation.
Book in the offseason.

Frequently Asked Questions
You can add a roof to most decks, but you need to have it inspected first. If your deck didn’t come with a roof initially, it may not be able to handle the weight without some structural changes. You can add additional supports to your existing deck to safely add a roof, and tying your deck’s roof to an exterior wall can help add some structural stability, but remember these aren’t DIY projects and need to be left to a pro.
Aluminum patio roofs can make noise during rainstorms, though how much noise they make depends on how heavy it’s raining and if the roof is insulated or not. Light rain falling on your roof might sound soothing but if you live in an area with serious and consistent rainfall, the novelty of the sound might wear off. In any case, the rain you'll hear shouldn't sound louder than a normal conversation or air conditioner, about 50 dB to 55 dB.
Slate, clay, and concrete are the longest-lasting patio roof materials, with potential life spans of 100 years, 50 years, and 50 years, respectively. Metal roofs are the next most durable, with an average life span of around 50 years, followed by asphalt, which lasts 20 to 30 years. More affordable fiberglass patio roofs can last for between 15 and 30 years. Regular roof cleanings will extend the life span of any material, so make sure you’re consistent with cleanings and any required maintenance.
A terrace is a flat area that’s raised slightly above ground level while a patio is built at the same level as the door leading into the house. Because of this, terraces usually aren’t connected to the living areas of a home but are commonly found around pools and fire areas.
