Find out how long it will last, and any upkeep you can do
Adding a pergola to your garden is a great way to create a stylish and functional outdoor space. But before investing in one, you may wonder, how long does a pergola last? The lifespan of a pergola depends on the material, maintenance, and weather conditions.
In this guide, we’ll explore the average lifespan of different pergola materials, factors that affect durability, and tips to help extend its life.
How Long Does a Pergola Last Based on Material?
The type of material used in a pergola plays the biggest role in determining its lifespan. Here’s what you can expect from different pergola materials.
1. Wooden Pergolas
Wooden pergolas can last between 10 to 20 years, depending on the type of wood and how well they are maintained.
- Cedar and Redwood – Naturally resistant to rot and insects, lasting around 15–20 years.
- Pine and Other Softwoods – Require regular sealing and may last 10–15 years.
To increase durability, wooden pergolas need regular staining, sealing, and protection from moisture.
2. Aluminium Pergolas
Aluminium pergolas can last 20+ years with minimal maintenance.
- Rust-resistant and durable
- Withstands rain, wind, and UV exposure
- Requires occasional cleaning but no sealing or staining
3. Steel Pergolas
A steel pergola lasts 10 to 25 years, depending on whether it is galvanised or powder-coated.
- Galvanised steel resists rust and lasts longer.
- Untreated steel can rust quickly in wet climates.
Regular maintenance, including protective coatings and rust prevention, is necessary for steel pergolas.
4. Vinyl Pergolas
Vinyl pergolas are low-maintenance and last 20–30 years.
- Does not rot, rust, or need staining
- Easily cleaned with soap and water
- May become brittle in extreme temperatures over time
A vinyl pergola is a great low-maintenance option but offers less customisation than wood or metal alternatives.
5. Fibreglass Pergolas
Fibreglass pergolas have the longest lifespan, lasting 30+ years.
- Resistant to moisture, rot, and UV damage
- Stronger than vinyl but more expensive
- Requires very little maintenance
Although fibreglass pergolas last the longest, they are one of the most expensive options.
Factors That Affect the Lifespan of a Pergola
Even the most durable pergola will not last if poorly maintained. Here are key factors that impact how long a pergola will stay in good condition.
1. Weather Conditions
- Pergolas in wet climates require more maintenance to prevent moisture damage.
- Strong winds and heavy storms can weaken structural integrity over time.
- Harsh sun exposure can fade and weaken certain materials like wood and vinyl.
2. Maintenance and Upkeep
- Wooden pergolas need sealing and staining every 2–3 years to prevent rot.
- Metal pergolas should be checked for rust and recoated as needed.
- Cleaning a pergola regularly helps prevent dirt buildup that can lead to wear and tear.
3. Quality of Materials
A well-built pergola using high-quality materials will always last longer than a cheap alternative. Investing in better materials and craftsmanship will save money in the long run.
4. Installation
A poorly installed pergola will weaken faster than one with strong foundations and secure anchoring. Hiring a professional or following proper installation guidelines will improve durability.
How to Make a Pergola Last Longer
