Composite Slate Roofing

Shingles made from splitting natural stone to produce slates have long been used as a roofing material. Recent technology has enabled manufacturers to create this beautiful look without the considerable expense of real slates. Composite slates are made by mixing particles from materials such as pulverized stone with plastic polymer resins that are heated and compressed into molds that resemble the shapes and texture of natural slate. These shingles are as fire and wind resistant as slates, but they weigh far less. They are also less likely to crack due to inclement weather conditions or heavy foot traffic.

If you are thinking of buying composite slate roofing, consider the following:

  • The composite slates come in the natural slate colors of grey, black, green and red. This allows for an authentic mixing of shades, resulting in a realistic appearance.
  • Most of these shingles come in 5 and 7 inch widths, so a variety of roof patterns are possible. Starter course, hip, and ridge shingles are also available.
  • Composite slates are easier to install than natural slates. They are easier to cut, and they can be attached with a pneumatic nail gun. They can also be hand nailed if that method is preferred.
  • When properly installed, composite slate shingles will provide a durable roof that is as maintenance free as natural slate.

If you live in an historic district or are hoping to take advantage of tax incentives for historic renovation, check with your state or local historical commission before using composite slate roofing to make sure that using a slate substitute is allowed.
