Colourbond vs Polycarbonate: Pergola Roof Replacement Guide

If your pergola or verandah roof shows signs of rust, has leaking seams, or creates a dark, damp environment, it’s time to think about a replacement. AWS Roofing is a specialist in pergola and verandah roof replacements across the Central Coast, Newcastle, and the Hunter Valley. We utilise high-quality materials such as Colorbond steel, polycarbonate, or a combination of both. This comprehensive guide will assist you in making informed decisions, highlight our recent pergola roof project in Gosford, and prepare you for requesting a quote.

Is It Possible to Replace Only the Roof of Your Pergola or Verandah?

Absolutely. You don’t always need to carry out a full renovation of your home to replace the roof. We can replace specific sections like a verandah or pergola roof independently, or as part of a larger re-roofing project. If you are replacing the main roof, it is often sensible to address the verandah or pergola at the same time, ensuring seamless integration of flashings and roof lines.

If your main roof shows similar signs of wear, consider obtaining quotes for both replacements. This approach allows you to weigh the benefits of tackling both projects together against handling them separately.

What Signs Indicate It’s Time for a New Pergola or Verandah Roof?

Keep an eye out for these warning signs that suggest your pergola or verandah roof may need replacement:

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

At AWS Roofing, we focus on complete roof replacements rather than patch repairs. We ensure that your outdoor area is fitted with new sheets, flashings, and fixings, which helps prevent further issues, especially during storm season.

How Do You Choose Between Colorbond Steel and Polycarbonate for Your Pergola Roof?

Your decision largely depends on the amount of natural light you want beneath the roof. Colorbond steel offers a robust roofing solution that provides complete shade and enhances your home’s exterior appearance. In contrast, polycarbonate allows natural light to filter through, making it a desirable choice for verandahs and pergolas where brightness is crucial.

Consider these options for your outdoor space:

• A solid Colorbond roof is ideal for creating a fully shaded outdoor area.
• A polycarbonate roof works well for a pergola or verandah where maximising natural light is a priority.
• A combination of both can offer a steel roof with strategically placed clear or tinted sheets to increase light entry.

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

Case Study: Pergola Roof Replacement in Gosford

A recent project in Gosford showcases the effective use of mixed materials. The original roof was a low-pitched corrugated metal structure. The homeowners wanted a design that complemented the pergola while ensuring the entertainment area remained well-lit. This was especially important during winter when a solid roof could make 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 incorporated 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 Is Best for a Verandah or Pergola Roof?

We offer Colorbond and Zincalume steel in three primary profiles, and your selection should reflect the roof’s pitch and the aesthetic you desire. These profiles are also suitable for complete house roofs:

• Custom Orb: The traditional corrugated profile, commonly found in Central Coast homes and sheds.
• Trimdek: A robust, cost-effective profile with prominent 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, ideal for long spans and lower-pitched roofs.

When requesting a quote, ask 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 Should You Consider When Choosing 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 house, it’s essential to view the colour in person. Online colour samples can often be misleading, so we advise comparing your choice against a physical sample before making a final decision. You can explore Colorbond colour samples at our showroom located at 3/3 O’Hart Cl, Charmhaven. We encourage you to visit and review your options.

If you would like to narrow down your choices in advance, 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.

Dealing with 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 be among them. 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 and follows SafeWork NSW regulations. We ensure that sheeting is safely removed and properly disposed of prior to installing the new roof. Our article on asbestos roof removal and replacement on the Central Coast discusses the factors that influence the cost.

What Steps Should You Follow to Replace a Pergola or Verandah Roof After Hail or Storm Damage?

Hail can cause substantial damage, resulting in dents and splits in roof sheets, while strong winds may dislodge flashings. Damage from a storm might be covered under your home insurance policy, so it’s wise to check your coverage before scheduling any repairs. You must contact your insurance provider, file a claim, and receive 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 thorough inspection report and quote for your insurer, and proceed with the roof replacement once the claim is approved. Detailed steps can be found on our storm and hail damage roofing page.

Essential Questions to Ask Before Scheduling a Pergola Roof Replacement

When gathering 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?

Common 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, as well as 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 correctly.

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

Yes. In the Gosford pergola roof project, we incorporated 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 exhibits 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 see 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 misleading, examining a physical sample is the most reliable way to match a new pergola or verandah roof with your home.
