Colourbond Vs Polycarbonate: Choosing Pergola Roof Replacement

If your pergola or verandah roof shows signs of rust, experiences leaks at the seams, or creates a dark, damp environment, it’s time to consider a replacement. AWS Roofing is the expert in pergola and verandah roof replacements throughout the Central Coast, Newcastle, and the Hunter Valley. We use high-quality materials such as Colorbond steel, polycarbonate, or a combination of both. This comprehensive guide will empower you to make informed choices, highlight our recent pergola roof project in Gosford, and prepare you for requesting a quote.

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

Absolutely. Not every roof replacement requires a complete overhaul of your home. We can replace individual sections such as a verandah or pergola roof independently, or as part of a larger re-roofing project. If you also need to replace the main roof, it’s practical to address the verandah or pergola at the same time. This ensures that the flashings and roof lines integrate seamlessly.

If your main roof is also showing signs of deterioration, consider obtaining quotes for both replacements. This will help you weigh the benefits of managing both tasks simultaneously versus handling them separately.

What Warning Signs Suggest Your Pergola or Verandah Roof Needs Replacement?

If you notice any of the following signs, it’s advisable to have your pergola or verandah roof assessed:

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

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

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

Your choice will mainly depend on the amount of light you want to allow into the space beneath the roof. Colorbond steel provides a robust roofing option that offers full shade and contributes a polished finish to your home’s exterior. In contrast, polycarbonate allows natural light to filter through, making it an attractive choice for verandahs and pergolas where brightness is essential.

Consider the following for your outdoor area:

• A solid Colorbond roof is ideal for creating a fully shaded outdoor environment.
• A polycarbonate roof is perfect 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 enhance light entry.

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

Case Study: Pergola Roof Replacement in Gosford

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

We replaced the existing roofing with 0.48 Trimdek in the Colorbond shade Ironstone. To maintain a flow of natural light, we incorporated two sheets of tinted 5 Rib polycarbonate into the new roof structure. The outcome is a modern, weather-resistant steel roof that creates a bright and welcoming atmosphere below. You can find 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 main profiles, and your choice will depend on the roof’s pitch and the aesthetic you desire. These profiles are identical to those used for full house roofs:

• Custom Orb: The classic corrugated profile, commonly seen in Central Coast homes and sheds.
• Trimdek: A durable, 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, 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 seem similar on paper may use different materials.

What Factors Should Influence Your Choice of 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 recommend comparing your choice against a physical sample before finalising your decision. You can explore Colorbond colour samples at our showroom located at 3/3 O’Hart Cl, Charmhaven. We encourage you to visit and explore 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 belongs to the premium colour collection.

Handling Old Verandah Roofs and Asbestos Sheeting

Many older homes, garages, and sheds in the Central Coast area may still have asbestos cement roofing, and an old verandah roof could fall into 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 safely removed and disposed of properly 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 Steps Should You Follow to Replace a Pergola or Verandah Roof After Hail or Storm 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 before 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 thorough 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.

Essential Questions to Consider Before Scheduling a Pergola Roof Replacement

When seeking multiple quotes for your pergola or verandah roof, consider asking these questions to gain clarity on 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 independently replace smaller roof sections, 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 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 shows 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.
