How we approach roof lanterns in Devizes
For Devizes homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
Devizes is around 27 km from Swindon, and we survey and fit throughout that part of Wiltshire, including the SN10 district.

What to check first

Consents for roof lanterns in Devizes
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Common questions
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
How do I book a survey in Devizes?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
