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).
