FAQ About Polycarbonate Installation: Expert Views on Slope and Waterproofing
Below is a list of FAQs that may help you:

1. How to Create a Slope?
Experts recommend creating at least a 5-degree slope. Here’s an easy calculation to achieve the required 5-degree slope: If you have a roof length of 12 feet, the upper roof end should be 1 foot taller than the lower end.
• Option 1: You can cut the whole beam diagonally to create two shims for the slope.
• Option 2: Install or reinstall the ledger board and attach it to the roof or the wall.

2. Is Flashing Necessary at the Edges of the Polycarbonate Roof?
You can use aluminum or galvanized metal flashings at the edges to ensure that rainwater doesn’t seep into the gaps between the polycarbonate panels and the beams.
Alternatively, you can use an overhang instead of flashing. An overhang extends the polycarbonate panels beyond the edge of the beam.
The maximum overhang is 12 inches.

3. List of Materials for Twin-Wall Polycarbonate Panel Installation:
• Polycarbonate Sheets: The main and key component.
• Connectors (H or Snap Profiles): Used to connect two sheets together.
• U Caps: Used to cover the ends of the sheets.
• Vented Tape: Protects against moisture and dust particles.
• Screws with Plastic Washers or Screws with Neoprene Washers: Ideal for preventing rainwater leaks.
• Silicone.
Tools:
• Measuring Tape: Essential for adjusting the polycarbonate sheets.
• Drill: Useful for creating precise screw holes.
• Circular Saw or Jigsaw: Used to cut and adjust panels.
• Safety Glasses: Protect against potential eye damage during installation.
• Ladder.

4. How to Calculate the Number of Screws
For proper installation, it’s recommended to place screws every 2 feet in each direction. At the same time, you should place screws where you have an H or snap connector.
Here’s a reference for a standard 4 ft x 8 ft sheet size:
• For one sheet (4 ft x 8 ft), you will need approximately 15 screws.
• For two sheets connected with an H or snap profile (4 ft x 8 ft), you will need around 25 screws.
• For three sheets connected with an H or snap profile (4 ft x 8 ft), you will need about 45 screws.
