Frequently Questions:
- Is a slope necessary for my pergola?
Slope is generally needed for any roofing system. A minimum slope of 5 degrees is recommended for effective water drainage. The slope helps with water drainage, this prevents water from accumulating on pergola roofing surface, ensuring longevity and preventing issues such as leaks.
If your pergola is flat, it's advisable to add shims to create slope.
2, What is the maximum span for my rafters without Sagging?
The maximum span for polycarbonate roofing on your rafters depends on the specific type of polycarbonate sheet and its thickness. The best rafter distance for flat polycarbonate roofing sheet is 600mm-800mm.
It's essential to refer to the manufacturer's guidelines or consult with a structural engineer to determine the appropriate maximum span for your project.
Recommend to consultant with pergola roofing sheets supplier first before you put the rafters on.
3,Is it necessary to install gutters and flashing for my pergola?
Yes, it is advisable to include gutters and flashing in your pergola design to manage water drainage effectively.
4, Why Aluminium H Joiner is important ?
Aluminium H-Joiners are essential for pergola roofing because they create waterproof seams between polycarbonate sheets while allowing for thermal expansion. Their rigid yet flexible design prevents leaks, supports the roof structure, and gives a clean finished look—unlike exposed screws or overlapping panels. Paired with Excelite's 2mm-4mm thick sheets, they form a durable, weatherproof system that outperforms traditional corrugated roofing.
5, Why you should avoid drilling Holes in Polycarbonate Roofing Sheets
While drilling is possible, minimizing holes in polycarbonate roofing sheets is ideal for these reasons:
✔Risk of Cracks & Weak Spots
- Polycarbonate expands/contracts with temperature changes.
- Drilled holes create stress points that can lead to cracking over time
✔Water Leakage
- Even with sealant, screw holes degrade over time due to UV exposure and thermal movement.
- Water can seep through, causing rot or mold in underlying structures.
✔Better Alternatives Exist
- Aluminum H-Joiners: Provide a waterproof, strong connections.
When Drilling is Necessary:
If you must drill:
✔ Oversize the holes to allow expansion room, Use UV-resistant EPDM washers
✔ Keep holes at least 2x diameter from sheet edges (e.g., 6mm hole = 12mm from edge).

- Impact Resistance: The clear polycarbonate roofing sheets have remarkable impact resistance, making them a durable option for areas prone to hail, storms, or falling debris.
- Heat Insulation: The clear polycarbonate roofing sheets provide excellent thermal insulation properties, maintaining a comfortable interior temperature while still allowing abundant natural light into your space, reducing energy costs for heating and cooling.
Applications
Clear polycarbonate roofing sheets are suitable for a wide range of applications, providing a transparent yet durable roofing solution:
- Greenhouses and Sunrooms: High light transmission and UV protection make clear polycarbonate roofing sheets perfect for greenhouses and sunrooms, allowing for an optimal environment for plant growth while protecting them from harmful radiation.

Choosing The Right Roofing Sheet
Polycarbonate roofing sheets are available in various types, each offering distinct benefits and characteristics. Understanding the differences between these sheets can help you choose the most suitable option for your roofing project. In this section, we compare clear polycarbonate roofing sheets with other popular types such as tinted, frosted, and multiwall polycarbonate sheets.
- Clear Polycarbonate Roofing Sheets: Clear polycarbonate roofing sheets offer high light transmission, UV protection, and excellent impact resistance. These sheets are ideal for applications where maximum transparency and natural light are essential, such as greenhouses, sunrooms, and patios.
- Tinted Polycarbonate Roofing Sheets: Tinted polycarbonate roofing sheets provide a similar level of impact resistance and UV protection as clear sheets while adding the benefit of reduced glare and heat transmission. The tinted sheets offer solar control by reducing the amount of sunlight and heat that passes through, making them ideal for roofing areas where some shading or privacy is desired without sacrificing durability.
- Frosted Polycarbonate Roofing Sheets: Frosted polycarbonate sheets offer a unique combination of strength, impact resistance, and light diffusion. Their textured surface diffuses light, creating a soft, even glow without glare. The frosted finish also provides a level of privacy while still allowing natural light to pass through. These sheets are suitable for applications that require a balance of privacy, light transmission, and durability, such as decorative partitions, skylights, and roofing solutions where a subtle, diffused light effect is desired.
Multiwall Polycarbonate Roofing Sheets: Multiwall polycarbonate sheets consist of multiple layers, providing exceptional thermal insulation and enhanced rigidity. These sheets maintain high impact resistance and UV protection while offering improved energy efficiency due to their insulating properties. They also contribute to noise reduction, making them suitable for roofing solutions in areas where noise control is a concern.

General
Polycarbonate is extremely strong and nearly unbreakable, making it suitable for applications like police shields, awnings, sunroom roofing, and greenhouses. These panels are resistant to various weather conditions and maintain their appearance for many years.
Polycarbonate sheets can be easily cut using a circular saw or a jigsaw. Circular saws are best for cutting larger lengths, while jigsaws require careful handling to ensure proper cuts.
Although polycarbonate sheets may change colour over time due to sun exposure, Excelite's UV-coated polycarbonate sheets maintain their colour longer.
Polycarbonate sheets require minimal maintenance. Gentle cleaning with warm soapy water and a soft cloth is typically sufficient. Avoid abrasive cleaners, brushes, or pressure washing, as these may damage the UV-resistant coating or scratch the sheets
Roofing
The best sheeting for a roof depends on the specific requirements, with multi-wall, solid, and corrugated polycarbonate sheets each offering unique benefits.
Although polycarbonate sheets are tough and durable, they should not be walked on. They can withstand many impacts, but might dent or scratch under the weight of a person. Additionally, their surfaces are slippery due to the UV-resistant film, posing a risk of slipping and injury.
Corrugated and twin wall polycarbonate sheets are typically the least expensive varieties. Despite the lower price, these sheets can endure Australia's harsh weather conditions, but selecting the wrong type may lead to more expenses in the long term.
Pergolas & Greenhouses
Excelite's popular glass-look polycarbonate flat roofing is an excellent choice for a pergola roof. It is easy to install, low-maintenance, and watertight, making it a great alternative to glass.
or a pergola enclosure with a glass-like appearance, use a 4-6mm thick solid polycarbonate sheet. Alternatively, use twin-wall polycarbonate panels for a more affordable, yet less transparent option.
Twin wall polycarbonate is ideal for greenhouse construction due to its insulating properties and minimal framing requirements. Excelite Softlite polycarbonate sheets are another excellent option for greenhouse materials, especially for tunnel greenhouses.
