Roof Replacement: Comparing Colourbond and Polycarbonate for Pergolas

If you observe rust, seam leaks, or a persistently dark and damp environment under your pergola or verandah roof, it’s time to explore replacement options. At AWS Roofing, we specialise in pergola and verandah roof replacements throughout the Central Coast, Newcastle, and the Hunter Valley, using premium materials like Colorbond steel, polycarbonate, or a combination of both. This comprehensive guide will help you make informed decisions, highlight our recent pergola roof project in Gosford, and assist you in requesting a quote.

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

Absolutely. You do not need to replace the entire roof of your home for smaller sections like a verandah or pergola. We can replace these roofs independently or as part of a larger re-roofing project. If you are also replacing the main roof, it is often advantageous to address the verandah or pergola simultaneously. This approach ensures that the flashings and roof lines are seamlessly integrated.

If your main roof shows signs of wear, consider obtaining quotes for both the main roof and the pergola or verandah. This allows you to weigh the benefits of tackling both projects together versus handling them separately.

What Are the Warning Signs That Your Pergola or Verandah Roof Needs Replacement?

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

• Visible 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 winter
• 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 emphasis is on complete roof replacement, equipping your outdoor area with new sheets, flashings, and fixings, effectively preventing further problems during storm season.

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

Your choice mainly hinges on how much light you wish to allow into the area beneath the roof. Colorbond steel offers a robust roofing solution that provides complete shade and enhances your home’s exterior appearance. Conversely, polycarbonate allows natural light to filter through, making it an attractive choice for verandahs and pergolas where brightness is essential.

Consider the following options for your outdoor space:

• A solid Colorbond roof is ideal for creating a fully shaded outdoor area.
• A polycarbonate roof is suitable for a pergola or verandah where maximising light is a priority.
• 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, offering the protection of a steel roof while allowing light to brighten the space during the cooler months.

Case Study: Pergola Roof Replacement in Gosford

A recent project in Gosford exemplifies the effective use of mixed materials. The original roof featured a low-pitched corrugated metal structure. The homeowners desired a roof design that would complement the pergola and keep the entertainment area well-lit. This was especially important in winter, when a solid roof could render 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 beneath. You can view 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 choice will depend on the roof’s pitch and the desired aesthetic. These profiles are the same ones utilised for full house roofs:

• Custom Orb: The traditional corrugated profile, familiar in Central Coast homes and sheds.
• Trimdek: A sturdy, 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 employ 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 your home’s roof, gutters, or fascia, 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 finalising your choice. 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 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, part of the premium colour collection.

Addressing 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 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, ensuring compliance with SafeWork NSW regulations. We guarantee that the sheeting is removed safely and disposed of properly before installing the new roof. Our article on asbestos roof removal and replacement on the Central Coast outlines the factors that influence the cost.

What Steps Should You Take 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, so it is 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 manage 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.

What Essential Questions Should You Ask Before Scheduling a Pergola Roof Replacement?

When seeking multiple quotes for your pergola or verandah roof, consider asking these questions to gain clarity on the services being offered:

• 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 is 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 Regarding 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 requires replacement, 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 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.
