Colourbond Vs Polycarbonate: Pergola Roof Replacement Guide

If your pergola or verandah roof shows signs of rust, has leaks at the seams, or creates a dark and damp environment, it may be time for a replacement. At AWS Roofing, we specialise in pergola and verandah roof replacements throughout the Central Coast, Newcastle, and the Hunter Valley, using high-quality materials like Colorbond steel, polycarbonate, or a combination of both. This comprehensive guide will assist you in making informed decisions, highlight our recent pergola roof project in Gosford, and prepare you for requesting a quote.

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

Absolutely. A roof replacement does not always require a complete overhaul of your entire structure. We can replace smaller sections, such as a verandah or pergola roof, either on their own or as part of a more extensive re-roofing project. If the main roof also shows signs of wear, it is often sensible to address the verandah or pergola simultaneously. This approach ensures that the flashings and roof lines integrate seamlessly.

If your main roof is also in need of attention, it’s wise to obtain quotes for both replacements. This allows you to weigh the benefits of tackling both projects together versus handling them separately.

What Indicators Suggest Your Pergola or Verandah Roof Needs Replacement?

Watch for these signs that indicate your pergola or verandah roof may require evaluation:

• Visible rust streaks or holes in the metal sheets
• Water leaking through 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 throughout winter
• Dents or splits from hail damage
• Old fibro-style sheeting that may contain asbestos

At AWS Roofing, we focus exclusively on complete roof replacements. We do not carry out patch repairs, ensuring that your outdoor area is fitted with new sheets, flashings, and fixings, which will help prevent further issues during storm season.

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

Your decision will largely depend on the amount of natural light you want beneath the roof. Colorbond steel offers a solid roofing option that provides complete shade and enhances the exterior of your home. Conversely, polycarbonate allows natural light to filter through, making it an attractive choice for verandahs and pergolas where brightness is essential.

Consider the following points 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 crucial.
• A combination of both can deliver a steel roof with strategically positioned clear or tinted sheets to improve light entry.

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

Case Study: Pergola Roof Replacement in Gosford

A recent project in Gosford demonstrates the effective use of mixed materials. The original roof was a low-pitched corrugated metal structure. The homeowners sought a 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 render the space dark and damp.

We replaced the existing roof with 0.48 Trimdek in the Colorbond shade Ironstone. To maintain 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 environment below. You can view project photos on our Gosford pergola roof project page.

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

We provide Colorbond and Zincalume steel in three primary profiles. Your selection will depend on the pitch of the roof and the aesthetic you desire. These profiles are the same ones used for full house roofs:

• Custom Orb: The traditional corrugated profile commonly seen in Central Coast homes and sheds.
• Trimdek: A durable, cost-effective profile with pronounced trapezoidal ribs, available in long lengths that can span from ridge to gutter without 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 a straightforward comparison between quotes, as two roofs that appear similar on paper may use 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 house’s roof, gutters, or fascia, it’s essential to view the colour in person. Online colour samples can often be misleading, so we suggest 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 welcome you to visit and review your options.

For those wishing to narrow down choices ahead of time, the complete range is available on our Colorbond colours page. The aforementioned Gosford pergola roof features Ironstone, which is part of the premium colour collection.

Handling 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, adhering to 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 outlines 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, leading to dents and splits in roof sheets, while strong winds can displace flashings. Damage to an outdoor roof from a storm might be covered under your home insurance policy, making it prudent to check your coverage before scheduling any repairs. You must contact your insurance provider, file a claim, and obtain written approval before we begin 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 can be found 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?

Commonly Asked 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 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 demonstrates 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.
