Roof Replacement: Colourbond vs Polycarbonate for Pergolas

If you notice signs of rust, seam leaks, or a consistently dark and damp environment beneath your pergola or verandah roof, it’s essential to consider replacement options. At AWS Roofing, we specialise 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 enable you to make informed choices, showcase our recent pergola roof project in Gosford, and assist you in requesting a quote.

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

Certainly. It is not necessary to replace the entire roof of your home when dealing with smaller sections like a verandah or pergola. We can replace these roofs independently or as part of a comprehensive re-roofing project. If you are also replacing the main roof, it is often beneficial 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 showing signs of deterioration, it is wise to obtain quotes for both the main roof and the pergola or verandah. This allows you to assess the advantages of managing both projects together versus handling them separately.

What Signs Indicate Your Pergola or Verandah Roof Needs Replacement?

If you observe any of the following warning signs, it is prudent to have your pergola or verandah roof evaluated:

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

At AWS Roofing, we do not carry out patch repairs. Our focus is on complete roof replacement, providing your outdoor area with new sheets, flashings, and fixings to effectively prevent further issues during storm season.

How Should You Decide Between Colorbond Steel and Polycarbonate for Your Pergola Roof?

Your decision primarily depends on the amount of light you want to allow into the area beneath the roof. Colorbond steel provides a robust roofing solution that offers complete shade and enhances your home’s exterior aesthetics. On the other hand, polycarbonate allows natural light to filter through, making it an appealing choice for verandahs and pergolas where brightness is crucial.

Consider the following options for your outdoor space:

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

This hybrid approach is particularly advantageous 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.

Project Spotlight: Pergola Roof Replacement in Gosford

A recent project in Gosford showcases 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 and keep the entertainment area well-lit. This was especially important in 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 ensure an influx 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 inviting atmosphere beneath. You can view project photos on our Gosford pergola roof project page.

Which Metal Roofing Profile is Most Suitable for a Verandah or Pergola Roof?

We provide 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 used for full house roofs:

• Custom Orb: The classic corrugated profile, familiar in Central Coast homes and sheds.
• Trimdek: A durable, 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 that features 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 helps ensure a straightforward comparison between quotes, as two roofs that seem similar on paper may utilise 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 your home’s roof, gutters, or fascia, it is crucial 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 your 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 wish to narrow down your choices beforehand, the complete range is available on our Colorbond colours page. The aforementioned Gosford pergola roof features Ironstone, 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 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 Actions Should You Take to Replace a Pergola or Verandah Roof Following 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 can 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 Key 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?

Frequently Asked Questions About Pergola and Verandah Roof Replacement

Do you only replace complete 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 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 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.
