This house has simple eave trim: a vertical 1\u00d78 with a gutter that creates a basic cornice. It doesn\u2019t make sense to use gutters on dormers because any rain is directed into the gutters below. To create a different yet still appropriate cornice molding, use a flat fascia board set on a 40\u00b0 to 45\u00b0 angle.<\/p>\n\n\n\n

Window size<\/h3>\n\n\n\n

J) Window size<\/h4>\n\n\n\n

When sizing windows, choose units that reflect the first-floor windows but are scaled-down by 10% to 25%. Keep the aspect ratio\u2014the proportion of a window\u2019s height to its width\u2014 the same, or make the windows slightly squat<\/p>\n\n\n\n

K) Egress<\/h4>\n\n\n\n

If any dormers are in a bedroom, remember that at least one window in each bedroom must meet code for egress. An egressable window has a distance from the floor no greater than 44 in., a minimum net-clear opening of 5.7 sq. ft., minimum width of 20 in., and a minimum height of 24 in. This does not mean that an opening of 20 in. by 24 in. meets code. For example, a 20 in.-wide window has to be at least 42 in. high to meet the 5.7-sq.-ft. requirement. Also, because only half of a double-hung unit can be opened at a time, the net-clear opening is drastically diminished\u2014down to 4.2 sq. ft. for the window in the drawing. Fortunately, manufacturers make casement windows that look like double-hung units for this purpose. For this project, such a casement window would have a net-clear opening of 8.4 sq. ft.<\/p>\n\n\n\n

L) Gable material
If the house details are simple, as they are here, matching the house siding is the conventional approach. If the house has more elaborate trim, or the dormers are particularly small, or if you want to add some visual interest, the gable and cheek walls can be finished and painted to match the trim. This makes the entire dormer a trim element.<\/p>\n\n\n\n

M) Sill height<\/strong>
Visually, less is best. Holding the sill at least 2 in. off the roof keeps the sill above snow and ice and creates a vertical dam against blowing rain.<\/p>\n\n\n\n
