How to build an upstand for your roof lantern?

Building a roof lantern upstand for Korniche and Wendland roof lanterns requires careful construction to ensure proper installation and performance. Here's a step-by-step guide to building a roof lantern upstand that is 150mm high and 70mm wide:

Materials and Tools You'll Need:

• Timber (pressure-treated) for framing
• Plywood or other suitable decking material
• Nails or screws
• Hammer or screwdriver
• Measuring tape
• Spirit level
• Circular saw or hand saw
• Pencil
• Roofing felt or membrane
• Sealant
• Roof lantern installation kit (provided by manufacturer)

Instructions:

1. Prepare the Work Area:

   • Clear the work area and ensure you have enough space to work comfortably.

2. Measure and Mark:

   • Measure the opening on your roof where the roof lantern will be installed.
   • Deduct the size of the upstand (150mm high and 100mm wide) from the opening measurements to determine the size of the hole you need to cut.

3. Cut the Timber:

   • Cut pressure-treated timber to create a frame for the upstand. You'll need four pieces: two longer pieces for the sides and two shorter pieces for the ends. Make sure the dimensions match the desired upstand size.

4. Assemble the Frame:

   • Assemble the timber pieces to form a rectangular frame, ensuring that the corners are square. Use nails or screws to secure the corners. Use a spirit level to check for level and plumb.

5. Install Decking Material:

   • Attach a piece of plywood or suitable decking material to the top of the timber frame. This will serve as the base for the roof lantern.

6. Install the Upstand:

   • Lift the assembled frame into the opening on the roof. Make sure it fits snugly and is properly aligned. Use a spirit level to ensure the upstand is level and positioned correctly.

7. Secure the Upstand:

   • Secure the upstand to the roof structure using appropriate fasteners. Make sure it's anchored securely to prevent any movement.

8. Waterproofing:

   • Apply roofing felt or a waterproofing membrane to the top of the upstand. This will provide an additional layer of protection against water infiltration.

9. Install Roof Lantern:

   • Follow the specific installation instructions provided by the manufacturer for the Korniche or Wendland roof lantern. This typically involves placing the roof lantern onto the upstand and securing it using the provided installation kit.

10. Seal and Finish:

    • Apply sealant around the edges of the roof lantern where it meets the upstand. This will help prevent water leakage and ensure a watertight seal.

11. Final Inspection:

    • Inspect the installation to ensure that the roof lantern is securely attached, level, and properly sealed. Check for any gaps or potential issues that need to be addressed.

Always refer to the manufacturer's installation instructions and guidelines for your specific roof lantern model. If you're not experienced with construction or roofing work, it's recommended to consult with a professional contractor to ensure a safe and proper installation.
