If you look at most conservatory roof designs you might be forgiven for thinking that Victorian conservatories all had ornate ridges with elaborate finials at the apex of a low hexagonal-shaped end with all the windows having a line of fanlight vents beneath the eaves and with a transom beneath each one. In fact conservatories and conservatory roofs of this era looked nothing like this design; instead, larger roof-to-wall windows interspersed with a few fanlights were more common along with steeply pitched roofs with plain ridges.

Raising the conservatory roof pitch to 40 or even 50 degrees will make the glass roof dominant on the elevation sides but this in the main does not look out of place. If it does on your home and you still want to go for a steep roof it may be enough to locate the conservatory away from the principal entrance and front elevation. A more discreet site for it may have to be found, ideally a rear or side gable end if the position of the first floor windows will allow it. Even if the conservatory roof pitch differs, extending the home out from a gable wall with a scaled-down gable-ended addition always appears sympathetic.
