Colourbond vs Polycarbonate: Pergola Roof Replacement Guide

If your pergola or verandah roof shows signs of rust, leaks at the seams, or creates a dark and damp environment, it’s time to think about a replacement. AWS Roofing is your go-to expert for pergola and verandah roof replacements throughout the Central Coast, Newcastle, and the Hunter Valley. We utilise high-quality materials like Colorbond steel, polycarbonate, or a combination of both. This comprehensive guide will empower you to make informed decisions, highlight our recent pergola roof project in Gosford, and prepare you to request 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 smaller sections like a verandah or pergola roof independently or as part of a broader re-roofing project. When replacing the main roof, it can be advantageous to address the verandah or pergola simultaneously. This ensures that the flashings and roof lines integrate seamlessly.

If your main roof is also exhibiting wear, consider obtaining quotes for both options. This will enable you to weigh the benefits of completing both tasks together against tackling them separately.

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

If you observe any of the following signs, it’s wise 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
• Dents or splits caused by hail damage
• Old fibro-style sheeting that may contain asbestos

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

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

Your decision largely hinges on the amount of light you wish to let into the space beneath the roof. Colorbond steel offers a robust roofing solution that provides total shade and enhances your home’s exterior. On the other hand, polycarbonate allows natural light to stream through, making it an attractive choice for verandahs and pergolas where brightness is a priority.

Consider the following for your outdoor area:

• A solid Colorbond roof is perfect for creating a fully shaded outdoor space.
• A polycarbonate roof is ideal for a pergola or verandah when maximising light is essential.
• A combination of both can offer a steel roof with strategically positioned 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 the 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 desired a roof design that would enhance 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 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 provide Colorbond and Zincalume steel in three primary profiles, and your choice will depend on the roof’s pitch and the aesthetic you prefer. 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-efficient profile featuring pronounced trapezoidal ribs, available in long lengths to span from ridge to gutter without end laps.
• Klip-Lok: A concealed-fix profile that has 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 will facilitate a straightforward comparison between quotes, as two roofs that appear similar on paper may utilise different materials.

What Should You Keep in Mind 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 home, it’s essential to view the colour in person. Online colour samples can often be misleading, so we advise comparing your selection against a physical sample before making a final decision. You can check out 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 prefer 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.

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 that 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 complies with SafeWork NSW regulations. We ensure 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 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 may displace flashings. Storm damage to an outdoor roof 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 secure 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 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 Consider 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 handle the removal and disposal 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, 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 properly.

Can light 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 brighten the entertaining area below.

Will you repair a leak in my verandah roof instead of replacing it?

AWS Roofing does not offer 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.
