Roof Replacement: Comparing Colourbond and Polycarbonate for Pergolas

If your pergola or verandah roof shows signs of rust, has leaks at the seams, or creates a dark, damp environment, it’s time to think about replacing it. AWS Roofing is a specialist in pergola and verandah roof replacements throughout the Central Coast, Newcastle, and the Hunter Valley. We utilise high-quality materials including Colorbond steel, polycarbonate, or a mix of both. This comprehensive guide will assist you in making 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. You don’t need to undertake a full renovation of your home for every roof replacement. We can replace specific sections like a verandah or pergola roof independently, or as part of a broader re-roofing project. If you’re replacing the main roof, it’s often beneficial to address the verandah or pergola simultaneously. This ensures that the flashings and roof lines integrate seamlessly.

If the main roof is also exhibiting wear, consider obtaining estimates for both options. This will allow you to weigh the benefits of handling both tasks together versus separately.

What Indicators Suggest Your Pergola or Verandah Roof Needs Replacement?

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

• Visible rust stains or holes in the metal sheets
• Water leaking through seams or edges where the roof meets the building
• Cloudy, cracked, or brittle polycarbonate sheets
• A shaded area that remains dark and damp throughout the winter months
• 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 focus is solely on complete roof replacements, ensuring your outdoor area features new sheets, flashings, and fixings to prevent further issues during storm season.

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

Your decision primarily hinges on how much light you want to allow into the space beneath the roof. Colorbond steel offers a robust roofing solution that provides total shade and enhances your home’s exterior aesthetics. On the other hand, polycarbonate allows natural light to filter through, making it an attractive option for verandahs and pergolas where brightness is important.

Consider the following for your outdoor area:

• A solid Colorbond roof is perfect for creating a fully shaded outdoor environment.
• A polycarbonate roof is ideal for a pergola or verandah where maximising light is crucial.
• 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 still allowing light to brighten the space during cooler months.

Showcase Project: Pergola Roof Replacement in Gosford

A recent project in Gosford exemplifies the effective use of mixed materials. The original roof consisted of a low-pitched corrugated metal structure. The homeowners desired a roof design that would complement the pergola while ensuring the entertainment area remained well-lit. This was especially vital in winter when a solid roof could make the space feel 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 outcome is a modern, weather-resistant steel roof that creates a bright and inviting atmosphere beneath. 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 look you wish to achieve. These profiles are the same ones used for complete house roofs:

• Custom Orb: The classic corrugated profile, commonly seen 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 featuring 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 use 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 house, 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 welcome you to visit and review your options.

If you prefer to narrow down your choices beforehand, the complete range is available on our Colorbond colours page. The Gosford pergola roof previously mentioned 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 area 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 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 dislodge flashings. Damage from a storm to an outdoor roof may be covered under your home insurance policy, making it 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 obtaining 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 cost?
• 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 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 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. As 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.
