Slate Like?

May 22, 2012

I thought that you might like to be introduced to a product that looks like slate but is made of recycled materials.  We are currently installing this product on a beautiful church roof and a historic building in downtown Lancaster.  The product is made of up to 80% recycled post-industrial rubber and plastic.  It is extremely environmentally friendly.  Synthetic slate recycled material looks like real slate roofing

I think that the installed product looks just like the original slate roof must have looked.  The procedure for installing the product is very similar to installing slate.  Growing up in the roofing business, I was involved in many slate roof installations.  Starting with cleaning up the mess from the old roof, then getting the new slates up to the roof, and later on installing the slate roofing and flashing.



  • Less weight than real slate.  The weight for this recycled product is less than half of what a slate roof weighs.
  • Environmentally friendly
  • Comes in a variety of colors
  • Can get a manufacturers 50 year limited material warranty
  • Costs slightly less than real slate
  • Less breakage



  • The first synthetic slate tiles have only been around since 1996 (Original slate roofs have been around for centuries)
  • Limited number of manufacturers
  • Takes about the same amount of time to install as slate

I think that this is a pretty cool product.  Time will tell if it will have the extremely long life expectancy of a real slate roof.  It would have been nice to have a product like this back when I was responsible for carrying slates around on the roof tops.
I am curious to know what your thoughts are.  What do you think about this recycled material versus real slate?

Great blog post. We have never come across slates made from recycled materials. It’s got to be a good idea at a time when we are running our of natural slate. Well done for making people aware of this resource.

What is the life expectancy on this material?

There is a 50 year warranty available from the manufacturer, but that doesn’t answer your question. As far as I know the material has only been in service for around 30 years or so. I’m sure they expect it to last 50 years, but only time will tell.

Do you think this will affect insurance? Nice blog though mate.

It doesn’t affect insurance here in the USA, but I’m not sure about in the UK.

Looks like a great option for folks interested in a sustainable material. How is it rated as far as fire resistance?

It can receive a UL Class A fire rating

Top rated then – great!
