Colourbond vs Polycarbonate: Choosing Pergola Roof Replacement

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 expert in pergola and verandah roof replacements throughout the Central Coast, Newcastle, and the Hunter Valley. We use 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 Just the Roof of Your Pergola or Verandah?

Absolutely. Not every roof replacement needs a complete overhaul of your property. We can replace smaller sections, such as a verandah or pergola roof, either individually or as part of a larger re-roofing project. When replacing the main roof, it’s often practical to address the verandah or pergola at the same time, ensuring seamless integration of flashings and roof lines.

If your main roof also shows signs of wear, consider obtaining quotes for both replacements. This enables you to weigh the benefits of managing both tasks together against handling them separately.

What Are the Key Signs That Your Pergola or Verandah Roof Needs Replacement?

If you notice 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 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 perform patch repairs. Our focus is on comprehensive roof replacement, ensuring your outdoor area features new sheets, flashings, and fixings to prevent future issues, especially during storm season.

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

Your choice mainly depends on the amount of natural light you want to let into the space beneath the roof. Colorbond steel offers a solid roofing solution that provides complete shade and enhances your home’s exterior. On the other hand, polycarbonate allows natural light to filter through, making it an attractive option for verandahs and pergolas where brightness is essential.

Consider these factors for your outdoor space:

• A solid Colorbond roof is ideal for creating a completely 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 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 permitting light to brighten the space during the cooler months.

Case Study: Pergola Roof Replacement in Gosford

A recent project in Gosford demonstrates the effective use of mixed materials. The original roof comprised a low-pitched corrugated metal structure. The homeowners sought a roof 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 leave the space 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 welcoming atmosphere below. You can view the project photos on our Gosford pergola roof project page.

Which Metal Roofing Profile Is Best for Your Verandah or Pergola Roof?

We offer Colorbond and Zincalume steel in three main profiles, and your choice 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, common in Central Coast homes and sheds.
• Trimdek: A robust, cost-effective profile with distinct 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 requesting a quote, inquire about the sheet profile and specify the Colorbond or Zincalume products by name. This facilitates an uncomplicated comparison between quotes, as two roofs that appear similar on paper may utilise different materials.

What Should You Consider When Choosing 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 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 encourage you to visit and review your options.

If you wish to narrow down your choices beforehand, the complete range is available on our Colorbond colours page. The previously mentioned Gosford pergola roof features Ironstone, part of the premium colour collection.

Addressing 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 specialist 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 correctly 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, leading to 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, so it’s wise to check your coverage before scheduling any repairs. 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 Your Pergola Roof Replacement

When seeking multiple quotes for your pergola or verandah roof, consider these questions to gain clarity on your investment:

• 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 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, along with full house and commercial roofs. If your main roof also requires replacement, addressing the outdoor roof during the same visit ensures proper integration of flashings and roof lines.

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 perform patch repairs or leak fixes. When an outdoor roof displays leaks at the seams, rust, or brittleness, we recommend a full 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.
