Colourbond vs Polycarbonate for Pergola Roof Replacement

If your pergola or verandah roof shows signs of rust, has leaking seams, or creates a dark and 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, using high-quality materials like Colorbond steel, polycarbonate, or a combination of both. This comprehensive guide aims to assist you in making well-informed choices, highlight our recent pergola roof replacement project in Gosford, and prepare you for requesting a quote.

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

Absolutely. Not every roof replacement requires a total overhaul of your home. We can replace specific sections like a verandah or pergola roof independently, or as part of a broader re-roofing project. Often, when replacing the main roof, it is sensible to address the verandah or pergola simultaneously, ensuring that the flashing and roof lines integrate seamlessly.

If your main roof is also displaying signs of deterioration, it’s wise to obtain quotes for both options. This allows you to weigh the benefits of managing both tasks together against handling them separately.

What Signs Suggest Your Pergola or Verandah Roof Needs Replacement?

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

• Prominent rust streaks or holes in the metal sheets
• Water seeping through seams or at the junctions where the roof meets the building
• Cloudy, cracked, or brittle polycarbonate sheets
• Areas that remain dark and damp during the winter months
• Dents or splits due to 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, thereby preventing further issues during storm seasons.

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

Your selection largely depends on how much light you want to let into the space beneath the roof. Colorbond steel offers a robust roofing solution that provides full shade and enhances your home’s exterior. On the other hand, polycarbonate allows natural light to filter through, making it a popular 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 perfect 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, allowing the protection of a steel roof while still permitting light to brighten the space during cooler months.

Highlighted Project: Pergola Roof Replacement in Gosford

A recent project in Gosford showcases the effective use of mixed materials. The original roof consisted of 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. This was especially important in winter when a solid roof could leave the space feeling dark and damp.

We replaced the existing roof 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 result is a modern, weather-resistant steel roof that creates a bright and inviting atmosphere below. You can view project photos on our Gosford pergola roof project page.

Which Metal Roofing Profile Works Best for a Verandah or Pergola Roof?

We provide Colorbond and Zincalume steel in three main profiles, with your choice depending on the roof’s pitch and the aesthetic appeal you desire. 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 robust, cost-effective profile with prominent trapezoidal ribs, available in long lengths to cover from ridge to gutter without needing end laps.
• Klip-Lok: A concealed-fix profile with 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 straightforward comparisons between quotes, as two roofs that appear similar on paper may utilise different materials.

What Considerations Should You Keep in Mind 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 decision. You can explore Colorbond colour samples at our showroom located at 3/3 O’Hart Cl, Charmhaven. We invite you to come 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 area 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, 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 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 can displace flashings. Damage to an outdoor roof from a storm may be covered under your home insurance policy, so it’s wise to verify 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.

Essential Questions to Ask Before Scheduling a Pergola Roof Replacement

When seeking 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 independently replace smaller roof sections, including verandah and pergola roofs, alongside full house and commercial roofs. If your main roof also needs replacement, addressing the outdoor roof during the same visit ensures that the flashings and roof lines integrate correctly.

Can I allow light to penetrate 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 demonstrates leaks at the seams, rust, or brittleness, we recommend a complete roof section replacement to ensure 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 misleading, examining a physical sample is the most reliable way to match a new pergola or verandah roof with your home.
