-2-The dormer construction of the past has required days or even weeks to complete, talus recoloring the opening in the roof to be maintained for a considerable period of time.
Maintaining the opening the roof for any considerable period of time is undesirable due to the vagarities of weather and is particularly undesirable in winter during cold weather.
Further, the construction of a dormer at the roof level of a house from individual pieces of lumber and the like requires a considerable amount of tune even under the best circwnstances and is somewhat dangerous for workmen.
Accordingly, with prior dormer structure and methods of construction, there is risk of damage to the building structure in which the dormer is to be placed and to the surrounding site as well as risk of injury to workmen. Dormer construction is thus more complicated and expensive than necessary using prior structllres and methods.
