Roof Windows

DormersA roof window is an outward opening window that is incorporated as part of the design of a roof. Often confused with a skylight, the roof window does differ from each of these other architectural and natural lighting elements in a few basic ways. A roof window is often a good option when there is a desire to allow both light and fresh air into the space.

A roof window tends to be larger than a skylight, making it possible to enjoy a wider view of the sky overhead. In addition, skylights are usually stationary; that is, they cannot be opened and closed. With some designs of a roof window, it is possible to retract a portion of the glazed panes to allow in fresh air as well as enjoy the natural light.

A roof window is also different from a tubular skylight, in that the light is not directed through any type of channel or tube in order to provide lighting for the interior of a building. This type of light tube design is often employed with buildings where the installation of a skylight or roof window is not practical.

While a roof window is normally included in the original construction of the building, it is possible to add the design feature to an existing structure. As long as the framework and the slope of the roof allow for the inclusion of this type of window, it can be installed with relative ease.

Felt Roofing has been around  since 1900, the mineral-faced form of asphalt-impregnated felt began to be supplied as roofing shingles cut into individual rectangles at first, then after about 1915, as strips with notches that stimulated the butts of two or three individual shingles. This form is still around today with little change except for a wider variety of colours and butt designs in the felts.
The mineral felt could be installed in a number of ways, such as: mechanical fasteners, hot asphalt, cold asphalt adhesive, non-asphaltic adhesives, heat (torch or hot air) or a combination of these. Lastly, there is often a layer of solar-reflective stones spread over the surface of the mineral felt. The presence of these stones protects the felt surface from the damaging effects of the sun’s rays.
