Slate is a dense, durable material mined from quarries mostly located in the eastern United States such as Vermont and Pennsylvania. Roofing slate comes in many different sizes, thicknesses, and colors.
Standard roofing slate is 3/16 to 1/4 of an inch thick, but is available up to 2 inches thick if desired. The longevity of a slate roof can be anywhere from 50 years to 400 years depending on the quality of slate used and the skill level of the slate roofing contractor. There are many people who do roofing in NJ, but far fewer who can do a quality job with slate.
Similar to slate roofs, tile roofs are strong and long lasting. Tile is available in many different styles, colors, and sizes. The 3 most common materials used for making tile are clay, cement, and concrete. Cement and concrete roof tiles do not have the longevity of clay tiles but are less expensive. The 2 most common types of tile systems are “real” and “cosmetic”. In a real tile system, the tiles themselves are intended to provide the water shedding and drainage necessary to form a dry covering over the building. Clay roofing tile surfaces may also be decorated with an embossed pattern to resemble wood, slate, or stone. Un-glazed tiles are terra-cotta red, a color provided by iron oxide in the clay.
These systems more so than any other, must have a professional to install and maintain them. Like we said earlier, a qualified slate roofing contractor or tile roofing contractor can be difficult to find. Most performance issues relative to these systems are due to improper workmanship and not material defects. On existing slate and tile roofs, it’s a good idea to have them inspected at least once a year, looking for obvious defects like slipping pieces or delamination of the surface.
Trying to repair these roofs yourself or hiring a contractor without a thorough background is not recommended. Nailing and even walking on these types of roofs have their own unique considerations that only someone experienced in roofing would be familiar with. Make sure you make a well-informed choice.
