Colourbond vs Polycarbonate: Pergola Roof Replacement Guide

If your pergola or verandah roof shows signs of rust, leaks along the seams, or creates a dark and damp environment, it’s time to consider replacing it. AWS Roofing specialises 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 will equip you with the knowledge to make informed choices, highlight our recent pergola roof project in Gosford, and prepare you for requesting a quote.

Is Roof Replacement Possible for Your Pergola or Verandah Without Overhauling the Entire Structure?

Absolutely. You don’t need to undertake a full renovation of your home for every roof replacement. We can replace smaller sections, such as a verandah or pergola roof, either independently or as part of a more extensive re-roofing project. When replacing the main roof, it is often beneficial to address the verandah or pergola simultaneously, ensuring that the flashings and roof lines integrate seamlessly.

If your main roof is also exhibiting signs of wear, consider obtaining quotes for both options. This way, you can weigh the benefits of completing both tasks together against addressing them 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 streaks or holes in the metal sheeting
• 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 during the winter months
• Dents or splits caused by hail damage
• Old fibro-style sheeting that may contain asbestos

At AWS Roofing, we do not engage in patch repairs. Our focus is on complete roof replacements, ensuring your outdoor space is equipped with new sheets, flashings, and fixings, thereby preventing further issues during storm season.

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

Your decision largely depends on the amount of light you wish to allow into the area beneath the roof. Colorbond steel offers a robust roofing solution that provides complete shade and adds a polished finish to your home’s exterior. In contrast, polycarbonate allows natural light to filter through, making it an attractive 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 positioned clear or tinted sheets to enhance light entry.

This hybrid approach is especially 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.

Case Study: Pergola Roof Replacement Project 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 particularly 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 maintain a flow 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 below. You can view project photos on our Gosford pergola roof project page.

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

We offer Colorbond and Zincalume steel in three primary profiles, and your choice will depend on the roof’s pitch and the aesthetic you desire. These profiles are also used for full house roofs:

• Custom Orb: The classic corrugated profile, commonly found 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, perfect 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 enables 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’d 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 belongs to 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 discusses the factors that influence the cost.

What Process Should You Follow 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. Damage to an outdoor roof from a storm 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 obtain written approval before we begin 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 Your Pergola Roof Replacement

When seeking multiple quotes for your pergola or verandah roof, consider asking the following 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?

Common Inquiries Regarding 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, along with 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.

Is it possible to 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 offers shade and weather protection, while the polycarbonate sheets let natural light illuminate the entertaining space below.

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

AWS Roofing does not perform 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 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.
