Is slate a tripping hazard?

Frequently Asked Questions
In our opinion, no. We have sold lots of slate, and have never had any complaints that people were tripping on the cleft areas of properly installed slate. We have had some specifiers concerned about it, and have decided not to use slate, but those who went with it, were always happy, to our knowledge. One consideration is that there are usually some pieces within a slate shipment that the tile contractor should sort and not install.

Is cleft finished slate, a tripping hazard?

Heavy cleft finish of the slate can often be a tripping hazard. Most Slates are lightly clefted and are commonly used in Kitchen Flooring, Bathrooms and Patios. In a palette there may be a few tiles with very heavy clefting. The installer must take care of not using such tiles, as a heavily clefted tile can create an uneven surface and may pose a tripping hazard. But for all practical purposes it would be very wrong to claim clefted slate to be a tripping hazard.

What is a ribbon slate?

Frequently Asked Questions about Slate, Tile, Metal Roofing ...
Ribbon slates are Pennsylvania black slates that have small bands running through them. These ribbons contain a high amount of carbon that deteriorates much faster than the rest of the slate. This results in the slate becoming separated at the ribbon, allowing either the slates to fall out or water to penetrate the roof. Even so, ribbon slate roofs have still been known to last 50 to even 100 years if the roof is steep and well shaded.

Is a slate roof fireproof?

Frequently Asked Questions about Slate, Tile, Metal Roofing ...
Slate itself is fireproof. A slate roof is one of the most fire resistant roofs that exist. However, the wood deck under the slate is not fireproof. Often fires will jump from house to house as sparks hit adjacent roofs, igniting the surface if it is a flammable material. Many of the raging fires that engulf hundreds of houses every year would not occur if the houses were covered in slate.

Is DaVinci Synthetic Slate or Shake made from recycled materials?

DaVinci Roofscapes...Frequently Asked Questions
No. While other synthetic shingles are manufactured from recycled materials such as tires or milk bottles, it is our opinion that roofing materials are not a good use for recycled goods. Roofing shingles are exposed to extremely harsh conditions (extreme weather, extreme UV, extreme temperature). The only way to assure that a synthetic slate or shake will provide good service for 50 years or more is to produce those shingles to very exacting standards.
