Frequently Asked Questions

Q. How Does Inspire Slate Compare With “Real” Slate On Price?

A. The answer to this question is …”what type of slate?” Most slate sold in the US is imported from China with a minimal warranty and of variable quality. Inspire Slate is similarly priced to a good quality guaranteed Spanish slate, but has many inherent benefits. One extremely relevant and cost-saving advantage is that fixing times are vastly reduced. Please see the Features and Benefits section of this site for further details.



Q. How Is The Material Fastened To The Surface?

A. Galvanized steel nails driven through the slate, either manually or by nail gun. No drilling, clipping or hooks required.



Q. What Is The Minimum Roof Pitch Inspire Tiles Can Be Installed On?

A. 14 degrees (on a fully-boarded roof). This is very useful for extensions and other applications where the available roof slope may be limited.



Q. Why Are They Curved? A Natural Slate Is Flat.

A. This is intentional. The induced camber flattens and creates a tight fit when nailed in place.



Q. Is An Eaves (Soldier) Course Needed?

A. Yes. Standard slating principles apply.



Q. How Are The Ridges/Hips Fixed?

A. Nailed and overlapped. Dry-fix system much more secure than a bedded ridge. Cement does not adhere well to Inspire Slate.



Q. Does The Color Fade Drastically?

A. No, Inspire Slate is UV stable with the same color through-out.  It will weather, as does any roof covering, depending on location and exposure.



Q. How Do You Cut The Tiles?

A. Fine-toothed saw, disc cutter, or scored with a utility knife.



Q. Will Moss/Algae Grow On Inspire Slate?

A. Once again, this depends on the location and exposure of the site. Algae grows better on a laminar material, Inspire Slate is not laminar. To deter growth, string a copper wire across the length of the ridge.



Q. Is It A “Green” Recycled Product? What’s It Made From?

A. It’s not recycled… but it’s RECYCLABLE. Inspire Slate is made from limestone and virgin resins. Consequently there is greater control over the mix and the manufacturing process. The main problems experienced with using reclaimed inconsistent raw materials are due to the lack of control in the manufacture which can result in splitting, curling, etc. There are no such problems with Inspire Slate.



Q. How Are The Tiles Packaged/Delivered?

A. Individually strap-banded bundles of 25 slates… 1600 per pallet (or less). There is a delivery charge depending on location.



Q. Can The Material Be Used For Vertical Cladding?

A. Yes.
