Single storey extension - tiled roof vs lantern roof
Anonymous user 03/03/2024 - 2.55 PM
Hello,
As part of a refurb project we are planning a single storey extension to the rear of our property to replace an old conservatory. Opinion is divided in this house about whether we should go with a flat roof with a large roof lantern, ie an orangery, or a pitched, tiled roof with velux windows. We'd be sourcing our glass direct as the conservatory companies are hugely expensive for this bit of work, so hoping some of you are confident / good at tackling this kind of job. We'd like to let in as much light as possible, but if the cost of tiled and velux is massively less then we'll live with a bit less of a sky view.
So in terms of cost and longevity, and what you prefer to work with, would you recommend
flat roof with a lantern or
pitched roof with velux windows?
Thanks in advance :)
Are you a tradesperson and able to answer this question?
Hello There,
Both options are quite straight forward and not too expensive, we are specialists in Orangeries and also build Tiled Sunrooms.
ORANGERY
The roof for the Orangery must be made with the correct structural integrity ie 8 x 2 Joists with heavy duty joist hangers, doubled up and coach bolted, timber ferrings then OSB Board with Firestone Rubber or GRP Finish.
Topped of with a Double Hipped Edwardian Atrium. If this is Built with 50% Brickwork 50% Windows and the Roof is 75% translucent it wont require building regs
TILED ROOF
Depending on the Conservatory projection you would use 8 x 2 or 6 x 2 timbers in a Traditional Build Lean-to roof configuration. If you wanted an Edwardian Style Roof, this would require Structural Calculations and Pre-made Trusses
Velux's as required. Building Notice would be required for this
However always put in a Provisional Development Enquiry into planning just to protect yourself
Good Luck

flat roof with a lantern for the bigger light value ,all really depends on which direction the room is facing ,cost wise depends on materials there are upvc triple domes on the market that are just as competitive than 2-3 velux and of course the fitting labour wise is less expensive

mme, to start with you would need building regulations on a tiled roof and that would have to include all the existing, footings,insulaion, floor construction, it is very difficult to make the existing build comply so an orangery is the way forward, you will need steel to sit the glass on to make sure it does not move.
