Frequently Asked Questions - Roof Lanterns & Windows

Q1: Are roof lanterns energy efficient?
A1: Yes, roof lanterns can be very energy-efficient, especially with high-performance glass and proper insulation. Look for models with energy-efficient coatings that reflect heat, ideal for south-facing rooms to stay cooler in summer and warmer in winter.

Q2: What’s the best position for a roof lantern?
A2: Roof lanterns are best centered in the room to spread natural light evenly. A south-facing room will benefit from maximum sunlight, but even north-facing rooms can enjoy enhanced light thanks to the wide angle of light that roof lanterns provide.

Q3: Do roof lanterns need planning permission?
A3: Generally, no. Most roof lanterns fall under permitted development if they meet certain criteria:

Should not extend more than 150mm beyond the roof plane
Shouldn’t exceed the highest point of the existing roof
Must use obscure glass if on a side elevation below 1.7m from the floor

Q4: Can a roof lantern be added to an existing roof?
A4: Yes, roof lanterns can be added to both new builds and existing roofs. They’re a great option to modernize older flat roofs or upgrade conservatory roofs.

Q5: How are roof lanterns installed?
A5: Skypod roof lanterns come in easy-to-assemble kits with all parts included. However, precise installation is key, so professional installation is recommended to ensure proper fitting and insulation.

Q6: How do I maintain a roof lantern?
A6: Self-cleaning roof lanterns reduce maintenance by helping rainwater wash away dirt. Otherwise, clean every few months with a soft sponge and soapy water or specialized glass cleaner.

Q7: What is the recommended height from the floor for a roof window?
A7: Roof windows should be installed about 120cm from the floor for optimal light and visibility, particularly in lofts.

Q8: What are rooflights?
A8: Rooflights are flush-mounted windows on the roof, designed to bring natural light into dim areas without protruding from the roofline, making them ideal for discreet daylight enhancement.
