Pergola Roof Replacement Guide: Colourbond vs Polycarbonate

If your pergola or verandah roof is showing signs of rust, has leaks at seams, or creates a dark and damp atmosphere, it’s time to consider a roof replacement. AWS Roofing specialises in replacing pergola and verandah roofs throughout the Central Coast, Newcastle, and the Hunter Valley. We utilise high-quality materials such as Colorbond steel, polycarbonate, or a combination of both. This in-depth guide aims to help you make informed decisions, showcase our recent pergola roof project in Gosford, and prepare you for requesting a quote.

Can You Simply Replace the Roof of Your Pergola or Verandah?

Absolutely. Not every roof replacement requires a complete overhaul of your home. We can replace specific sections, such as a verandah or pergola roof, independently or as part of a broader re-roofing project. When replacing the main roof, it often makes sense to address the verandah or pergola simultaneously, ensuring that the flashings and roof lines integrate seamlessly.

If your main roof also shows signs of wear, consider obtaining quotes for both options. This allows you to weigh the benefits of addressing both tasks together versus separately.

What Are the Key Indicators That Your Pergola or Verandah Roof Requires Replacement?

Be vigilant for the following signs, as they suggest that your pergola or verandah roof needs to be assessed:

• Visible rust streaks or holes in the metal sheets
• Water leaking through seams or along the edges where the roof meets the building
• Cloudy, cracked, or brittle polycarbonate sheets
• An area that remains dark and damp during winter
• Dents or splits caused by hail damage
• Old fibro-style sheeting which may contain asbestos

At AWS Roofing, we do not perform patch repairs. Our focus is on complete roof replacements, ensuring your outdoor area is equipped with new sheets, flashings, and fixings, thus preventing further issues during storm season.

How to Decide Between Colorbond Steel and Polycarbonate for Your Pergola Roof

Your choice largely depends on the amount of natural light you want to allow into the space beneath the roof. Colorbond steel delivers a solid roofing solution that provides complete shade and a finish that enhances your home’s exterior. Conversely, polycarbonate permits natural light to filter through, making it an appealing option for verandahs and pergolas where brightness is essential.

Consider the following for your outdoor space:

• A solid Colorbond roof is ideal for creating a fully shaded outdoor area.
• A polycarbonate roof is perfect for a pergola or verandah where maximising light is crucial.
• A combination of both can provide a steel roof with strategically placed clear or tinted sheets to enhance light entry.

This hybrid approach is particularly beneficial for a pergola adjacent to a living area, allowing for the protection of a steel roof while still letting light illuminate the space during the cooler months.

Project Showcase: Pergola Roof Replacement in Gosford

A recent project in Gosford demonstrates the effective use of mixed materials. The original roof had a low-pitched corrugated metal structure. The homeowners sought a roof design that would complement the pergola while ensuring the entertainment area remained well-lit. This was especially critical in winter when a solid roof could leave the space dark and damp.

We replaced the existing roofing with 0.48 Trimdek in the Colorbond shade Ironstone. To maintain an influx of natural light, we integrated two sheets of tinted 5 Rib polycarbonate into the new roof structure. The result is a modern, weather-resistant steel roof that creates a bright and inviting atmosphere below. You can view the project photos on our Gosford pergola roof project page.

Which Metal Roofing Profile Suits a Verandah or Pergola Roof Best?

We offer Colorbond and Zincalume steel in three primary profiles, and your selection will depend on the roof’s pitch and the aesthetic you desire. These profiles are the same ones used for full house roofs:

• Custom Orb: The traditional corrugated profile, familiar in Central Coast homes and sheds.
• Trimdek: A robust, cost-effective profile with pronounced trapezoidal ribs, available in long lengths to span from ridge to gutter without end laps.
• Klip-Lok: A concealed-fix profile featuring no visible screws, perfect for long spans and lower-pitched roofs.

When requesting a quote, inquire about the sheet profile and specify the Colorbond or Zincalume products by name. This ensures a straightforward comparison between quotes, as two roofs that appear similar on paper may use different materials.

What Factors Should You Consider When Selecting a Colour for Your Colorbond Outdoor Roof?

If you want your new pergola or verandah roof to match the roof, gutters, or fascia of your home, it’s essential to view the colour in person. Online colour samples can often be misleading, so we recommend comparing your selection against a physical sample before making a final choice. You can explore Colorbond colour samples at our showroom located at 3/3 O’Hart Cl, Charmhaven. We invite you to visit and review your options.

If you wish to narrow down your choices beforehand, the complete range is available on our Colorbond colours page. The previously mentioned Gosford pergola roof features Ironstone, which is part of the premium colour collection.

Managing Old Verandah Roofs and Asbestos Sheeting

Many older homes, garages, and sheds in the Central Coast region may still have asbestos cement roofing, and an old verandah roof could fall under this category. If you suspect your verandah roof contains asbestos, do not attempt to drill, cut, sand, or water blast it. Asbestos sheeting requires specialised removal and cannot simply be stripped away like a metal roof.

AWS Roofing is licensed for asbestos roof removal, adhering to SafeWork NSW regulations. We ensure that the sheeting is removed safely and disposed of correctly before installing the new roof. Our article on asbestos roof removal and replacement on the Central Coast discusses the factors that influence the cost.

What Actions Should You Take to Replace a Pergola or Verandah Roof After Storm or Hail Damage?

Hail can cause significant damage, resulting in dents and splits in roof sheets, while strong winds may displace flashings. Damage to an outdoor roof from a storm might be covered under your home insurance policy, making it wise to check your coverage prior to scheduling any repairs. You must contact your insurance provider, file a claim, and obtain written approval before we commence any work.

We handle insurance work. While we do not negotiate with insurance companies, we can assist in documenting the damage for your claim, provide a detailed inspection report and quote for your insurer, and proceed with the roof replacement once the claim is approved. Detailed steps are available on our storm and hail damage roofing page.

Crucial Questions to Ask Before Scheduling a Pergola Roof Replacement

When obtaining multiple quotes for your pergola or verandah roof, consider asking these questions to clarify what you are paying for:

• What is your roofing licence number, and are you insured and WorkCover accredited?
• Which sheet profile and which Colorbond, Zincalume, or polycarbonate product is included in the quote, by name?
• Are new flashings and fixings included, or will any be reused?
• Who will be responsible for removing and disposing of the old roofing, and is that included in the price?
• Is there a written warranty, and does it cover both workmanship and materials?

Frequently Asked Questions About Pergola and Verandah Roof Replacement

Do you only replace full house roofs?

No. AWS Roofing can replace smaller roof sections independently, including verandah and pergola roofs, alongside full house and commercial roofs. If your main roof also needs replacing, addressing the outdoor roof during the same visit ensures that the flashings and roof lines integrate properly.

Can I allow light to filter through a new steel pergola roof?

Yes. In the Gosford pergola roof project, we integrated two sheets of tinted 5 Rib polycarbonate within a new Trimdek roof in Colorbond Ironstone. The steel provides shade and weather protection, while the polycarbonate sheets allow natural light to illuminate the entertaining area below.

Will you repair a leak in my verandah roof instead of replacing it?

AWS Roofing does not engage in patch repairs or leak fixes. When an outdoor roof shows signs of leaks at the seams, rust, or brittleness, we recommend a complete roof section replacement to ensure that all sheets, flashings, and fixings are new. We will provide a clear explanation of our recommendations for your pergola or verandah.

Where can I view Colorbond colours in person?

You can find Colorbond colour samples at the AWS Roofing showroom located at 3/3 O’Hart Cl, Charmhaven NSW 2263. Since colours displayed on screens can be deceptive, examining a physical sample is the most reliable way to ensure a new pergola or verandah roof matches your home.
