Preserving Old Roofs On Historic Homes
The roof--with its shape; features such as cresting, dormers, cupolas, and
chimneys; and the size, color, and patterning of the roofing material--is an
important design element of many historic buildings.
In addition, a weather-tight roof is essential to the long-term preservation of
the entire structure. Historic roofing reflects availability of materials,
levels of construction technology, weather, and cost.
For example, throughout the country in all periods of history, wood shingles
have been used--their size, shape, and detailing differing according to regional
craft practices. European settlers used clay tile for roofing as early as the
mid-17th century. In some cities, such as New York and Boston, clay was
popularly used as a precaution against fire. The Spanish influence in the use of
clay tile is found in the southern, southwestern and western states. In the
mid-19th century, tile roofs were often replaced by sheet metal, which is
lighter and easier to maintain. Evidence of the use of slate for roofing dates
from the mid-17th century. Slate has remained popular for its durability,
fireproof qualities, and its decorative applications. The use of metals for
roofing and roof features dates from the 18th century, and includes the use of
sheet iron, corrugated iron, galvanized metal, tin-plate, copper, lead and zinc.
Awareness of these and other traditions of roofing materials and their detailing
will contribute to more sensitive treatment.
