Decorative dormers range from $583 to $933, according to a 2013 report by Dryden Mutual Insurance. An average 10-by-15 shed dormer costs between $11,270 and $16,904, while the same size gable dormer ranges from $14,400 to $21,602.ut this extra bit of headroom comes with a high price tag, and dormer installation is not a DIY project. Plan to spend between $10,000 and $30,000 for your new dormer, depending on size and style.
A new dormer will usually need to be built when the stairs to the loft conversion are installed over the existing staircase between the ground and first floors of the property.f course, adding windows to the front of the dormer will not only give a great view from the new loft room but will also allow in lots of natural light and, importantly, give extra ventilation into the roof.
