Historic Roofing Materials: Wood Shingles

Before the development of asphalt and fiberglass shingles, wood shingles were popular in New York and throughout the country in all periods of building history. The size and shape of the wood shingles Bronx as well as the detailing of the shingle roof differed according to regional craft practices. People within particular regions developed preferences for the local species of wood that most suited their purposes. In New England and the Delaware Valley, white pine was frequently used: in the South, cypress and oak; in the far west, red cedar or redwood. Sometimes a protective coating was applied to increase the durability of the wood shingle Brooklyn such as a mixture of brick dust and fish oil, or a paint made of red iron oxide and linseed oil.

Commonly in urban areas, wooden roofs Queens were replaced with more fire resistant materials, but in rural areas this was not a major concern. On many Victorian country houses, the practice of wood shingling survived the technological advances of metal roofing in the 19th century, and near the turn of the century enjoyed a full revival in its namesake, the Shingle Style. Colonial revival and the Bungalow styles in the 20th century assured wood shingles a place as one of the most fashionable, domestic roofing materials.

Historic Roofing Materials: Metal

Early metal roofing included copper and lead in early america. These were typically used where the pitch of the roof prohibited other types of shingles for use. Beautiful New York copper roofs cover many of New York's fine historic buildings, especially those with cupolas, domes or other interesting architectural features. Sheet iron was first used in the 18th century.

It wasn't until the 19th century that New York Roofing installation included the use of corrugated iron. The method for corrugating iron was originally patented in England in 1829. Corrugating stiffened the sheets, and allowed greater span over a lighter framework, as well as reduced installation time and labor. In the late 19th century, galvanizing with zinc helped to protect the base metal of New York metal roofing.

Tin shingles were another metal roofing material Queens. Tin shingles were embossed to look like tile or wood or embossed with a decorative design. This was an inexpensive, lightweight roofing choice. The low cost, light weight, and low maintenance of tin metal roofing Bronx made it the most common roofing material in the late 19th century.

Historic Roofing Materials: Slate

Slate roofing was brought to America from the old world Europe by settlers. Slate roofing was found in America as far back as Jamestown in the mid-17th Century. Although there were slate quarries all along the east cost, most of the slate was imported from Wales. For that reason, there are few slate roofed homes until the 19th century when slate roofing became more common due to the construction of railroads and Canals. At that time, homes throughout New York were constructed with slate roofs. Many of them survive today.

New York Slate Roofing is popular for the same reasons it was popular 200 years ago. It maintains popularility due to its durability, fireproof qualities, and aesthetic beauty. New York Slate Roofing is available in different colors (red, green, purple, and blue-gray).

For owners of historic buildings it is important to find a contractor who is familiar with Slate roofing Bronx and Queens restoration and maintenance. Replacement of historic roofing details on Brooklyn homes, for example, requires an undestanding of historic preservation and how to incorporate new materials, such as flashing, to improve the historic properties of the roof and keep the original roof character.

Historic Roofing Materials: Clay Tile Roofs

In New York State, there are still a number of old homes with clay tile roofs. Clay tile roofing was used by Europeans as far back as the beginning of our country in mid-17th century America. S-curved tiles and flat tile roofing Queens were used in Colonies like Jamestown, Virginia. Roofing in New York City was made of clay for fire protection, a common problem in 17th and 18th century America.

Clay Tile: European settlers used clay tile roofing Manhattan as early as the mid-17th century; many pantiles (S-curved tiles), as well as flat roofing tiles, were used in Jamestown, Virginia. In some cities such as New York and Boston, clay was popularly used as a precaution against such fires as those that engulfed London in 1666 and scorched Boston in 1679.

By the mid-19th century, tile roofing in New York was frequently replaced by metal roofs. Sheet metal roofs were lighter and easier to install and maintain. The clay tiles were not often used again until the beginning of this century, when the Spanish style buildings created a new demand for tile roofing. Today, with a greater awareness of historic preservation, New Yorkers may want to maintain their Bronx or Queens tile roofing rather than Bronx roof replacement with convention asphalt shingles which do not reflect the historic qualities of old homes.
