Roofing Material History: The Asphalt Shingle

The First Composite Shingle was used in roofing in 1840s New England. The composite shingle of this time was typically made of felted wool rags, cotton, or paper. The saturated felt was then passed through a pan where a coating pine tar and sand was applied. Over time, improvements like saturating the fabric with asphalt and a mixture of materials like talc, sand, or powdered gravel or limestone, hence the name “composite” or “composition” shingle.

The first true composition roofing was made of coal tar, a byproduct of the gas lighting industry, and woven felt made of rolled wool, cotton, or paper saturated with the tar and fine gravel. In the last part of the nineteenth century, roll roofing emerged, and by the beginning of the twentieth century was commonplace.

The concept of forming asphalt roofing into individual shingles began soon after the turn of the century, credited to Henry M. Reynolds of Grand Rapids, Michigan in 1903. Mr. Reynolds began cutting stone-surfaced roofing into 8x16” shingles by hand with a knife. The addition of crushed slate granules added a weight that helped keep the shingles adhered to the roof.

Wood shingle roofs were banned in some places due to a rash of damaging fires causing asphalt shingles’ popularity to increase. Again they saw their popularity rise during World War I as they were made completely of non-strategic materials. However, at the invention of machinery for roller-die cutting thick roofing into irregular shapes on a continuous production line, a roofing material star was born.

In the 1970s, a glass fiber-reinforced felt with tensile strength, thinner and more light-weight, was introduced. Several layers of these felts were laminated together to give a dramatic shading effect. Many different colors and shapes of asphalt tiles have been manufactured over the years. Today, asphalt shingles are an enduring choice as the most popular roofing material for their affordability, ease of use, durability and availability.

Roofing Material History: The Clay Tile

Roofing Material History. We bet you woke up today hoping to learn more about ancient civilizations and their roofing methods and materials, didn’t you? We don’t blame you. It’s pretty interesting stuff. There have been many, many discoveries and advances in roofing materials and techniques since the dawn of time. Today we’re going to share a little but with you about the first roofing material implemented by mankind: the clay tile. Enjoy!

Clay Tiles are believed to to have first been used in Neolithic China as early as 10,000 B.C.. After that, the earliest record of their use is 5000 years ago, in Babylon, then making their way via Egypt and Greece to Rome. Rome was called “The City of Tiled Roofs”. The Romans were then responsible for making clay tiles the most popular roofing technique all across Europe for their great durability and attractiveness. Today, many thousands of years later, clay tiled roofs created by ancient Romans still exist.

The inflammability of clay roof tiles caused them to fall into favor in 1212 AD London as King John of England issued building by-laws for London to eliminate combustible roof coverings. The city of Boston followed suit after the devastating fires of 1679 prompted the establishment of building and fire codes in New York and Boston. Clay tiled roofs had become the standard in Europe by the 18th century, wherever there was an abundant local supply of suitable raw materials.

The craft of tile making in those days was very laborious, and required great knowledge and skill. Clay tile burning was done in piles, in which the tiles and burning material, like coal or wood, was layered into stacks and covered by earth.

Industrial production of clay roofing tiles was first begun soon after in the 19th century. The development took a bold leap forward to the interlocking, strong and durable clay roofing tiles with consistent quality and design we know today. Circa 1960, the mining of raw clay for tiles was taken over by machinery. Still popularly used in today’s 21st century, the quality and durability of materials used in the manufacture of clay roofing products makes them a great option, particularly for the value minded homeowner.
