Our Services
Roof Lanterns
Flood your home with natural light
More light, more room
A new roof lantern or flat rooflight can completely change a kitchen, an extension, or a tired conservatory, pulling daylight deep into the plan and making the whole room feel twice the size. For 16 years we have been fitting glazed roofs across Essex and East London, from small flat rooflights to full architectural lanterns.
Made to your opening
The range covers flat fixed rooflights for 0 to 15 degree pitches, architectural roof lanterns made to your exact opening, walk-on rooflights for upper-storey terraces, and full conservatory roof replacement. Manual and electric openers, self-cleaning glass, solar control tints, and frame colours across the full palette.
Certified, guaranteed, finished
Every lantern comes with a 10-year guarantee on the frame and the sealed unit, and every installation is certified under our Assure Competent Person Scheme. We handle the structural opening, the flashings, the internal plasterwork detail, and the building regulations sign-off, so the project is ready to use the day we leave.
Priority routes
Roof glazing depends on the opening and the room below
A raised lantern, flat rooflight, walkable rooflight, and opening rooflight solve different problems. On survey we look at the roof build-up, kerb height, room use, orientation, drainage, access, and whether the priority is a stronger architectural feature or a quieter low-profile glass panel.
