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 essential to consider a replacement. AWS Roofing specialises in pergola and verandah roof replacements across the Central Coast, Newcastle, and the Hunter Valley, using high-quality materials such as 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. Not every roof replacement requires a complete renovation of your home. We can replace specific sections, such as your verandah or pergola roof, either on their own or as part of a larger re-roofing project. If your main roof also requires attention, it is often beneficial to address the verandah or pergola simultaneously. This approach ensures that the flashings and roof lines align seamlessly.

If your main roof is also exhibiting signs of wear, it’s wise to obtain quotes for both options. This will enable you to weigh the benefits of tackling both tasks together against addressing them separately.

What Warning Signs Suggest Your Pergola or Verandah Roof Needs Replacing?

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

• Visible rust streaks or holes in the metal sheets
• Water leaking through seams or along 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 do not perform patch repairs. Our commitment is to complete roof replacements, ensuring your outdoor space is fitted with new sheets, flashings, and fixings, thus preventing further issues during storm season.

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

Your decision primarily hinges on the amount of light you wish to allow into the space beneath the roof. Colorbond steel offers a solid roofing solution that provides complete shade and gives a polished finish that enhances your home’s exterior. Conversely, polycarbonate allows natural light to filter through, making it an attractive option for verandahs and pergolas where brightness is essential.

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 placed clear or tinted sheets to enhance light entry.

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

Case Study: Pergola Roof Replacement Project in Gosford

A recent project in Gosford demonstrates the effective use of mixed materials. The original roof featured a low-pitched corrugated metal structure. The homeowners desired a roof design that would complement the pergola while ensuring the entertainment area remained well-illuminated. This was especially important in winter when a solid roof could leave the space dark and damp.

We replaced the existing roofing with 0.48 Trimdek in the Colorbond shade Ironstone. To ensure natural light continued to enter the space, we integrated two sheets of tinted 5 Rib polycarbonate into the new roof structure. The final result 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 offer Colorbond and Zincalume steel in three primary profiles, and your selection will depend on the roof’s pitch and the aesthetic you desire. These profiles are the same ones used for complete house roofs:

• Custom Orb: The traditional corrugated profile, commonly seen in Central Coast homes and sheds.
• Trimdek: A robust, cost-effective profile featuring pronounced trapezoidal ribs, available in long lengths to 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 seeking 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 Should You Consider 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 vital to view the colour in person. Online colour samples can often be misleading, so we recommend comparing your choice 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 encourage you to visit and review your options.

If you would like 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.

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 your old verandah roof might 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 metal roofing.

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 details 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 the 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’s 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 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 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 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?

Frequently Asked 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 let 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 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 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.
