A roof lantern or skylight transforms a single-storey extension or rear kitchen-diner into a light-filled space without adding height. S&K Glazing installs Korniche, Atlas and Stratus aluminium roof lanterns up to 5m wide, plus flat skylights and walk-on glass floors with self-cleaning, solar-control glass.

Our process

From survey to installation in 4 steps

01

Survey & design

We measure the rooflight aperture and check structural opening, kerb height and timber framing. We help you choose between traditional roof lantern (pitched ridge) and modern flat skylight.

02

Manufacture

Korniche lanterns: 1-2 week lead time. Custom Atlas or Stratus: 3-4 weeks. Flat skylights: 2-3 weeks for standard sizes.

03

Roofer coordination

Roof lantern installation usually requires coordination with your roofer to fit upstand kerbs first. We can supply pre-fabricated kerbs or work alongside your roofer.

04

Glazing & weatherproofing

Glass panels delivered and craned/lifted into position, sealed with structural silicone, and finished with lead flashing or EPDM weather seals.

FAQs

Roof Lanterns & Skylights questions, answered

Properly installed roof lanterns with self-cleaning solar-control glass and pre-fabricated kerbs are extremely reliable. We've installed thousands and seal failures are vanishingly rare. 10-year warranty included.
