When will slate fight back?


Slate is one of the more complex roofing materials with regard to its distribution and success. It holds about a 1% foothold in the overall roofing chart pie, maybe less. A simple goal would be to grow it to 2%. Yet, numbers don’t lie and we’ll see that this industry is trending in the wrong direction.

America’s Mentality & Europe’s Example

The slate industry is not growing because America’s mindset is that of a quick buck. Pride in building, with our lack of trade schools, is at an all-time low. Building’s are not built to last. Contractor’s are asked to use cheap materials and complete projects as soon as possible. These structures over time will develop issues. This is today’s standard for far too many projects. Consider France & Germany where slate is a primary building material on roofs and walls. Their model and their use of slate would have to be followed if the use of slate were to grow in the USA. Here are 3 main concerns:

Installation – Hook systems are used to reduce labor time thus lowering the cost.

Self Satisfaction – European homes are passed down from generation to generation. It makes sense to build them to last with durable materials like slate, stone and brick.

Trade Schools – Being a roofer is looked at as a reputable profession in Europe. Roofers go to school for years and then fulfill an apprenticeship in order to be qualified. USA roofers need a ladder.

Europe’s Numbers Don’t Lie

Spain is the biggest exporter of slate and France is the biggest importer. France is a country of 68 million people which is about 20% the size of the USA. You can see that France imports between $160-$190 million dollars of slate a year from Spain.

France is the largest importer, but that’s still only about 50% of total export. Spain’s export is a $300 million market.

USA Imports & Exports

  • USA Total Exports

The main countries that buy slate from the US are Canada and the UK. Note that Slate is not big business being exported. Remember Spain exports almost $300 million, the US is around $5 million.

  • The US Imports in Total Tons From Spain

The import market is also small scale when compared to France.It’s relatively stable although I expect it to continue to grow with the lack of production from PA quarries and Spanish slate acting as a potential substitute.

What Does This Tell Us?

The first part to understand is that the US slate market is mainly internal with slate being produced in the New York / Vermont Slate region, Virginia, and Pennsylvania supplementing it. These numbers are not posted but a $50 million dollar estimate may be a ballpark. The export market is up to 5 million. The import is around the same. This means that France, a country of 66 million people, imports 3 times as much slate as all of the USA. Spain, a country of 45 million, is exporting about 5x the entire slate industry in the US each year. 

The point is that it’s not the material’s fault. It’s us. It’s our society. It’s big business. It’s a shift away from a traditional, permanent structure. It’s not wrong to adapt to changes, but we’re moving away from the beauty, longevity and integrity that a slate roof provides. Stepping up and fighting back has to start now.

Why Natural Slate On Roofs Is Not Growing In The USA

Drawbacks of slate is that it is an upscale, heavy material with a lack of skilled installers. It must be installed piece by piece which may be looked at as slow and laborious. The marketing budget of the industry is minuscule compared to other materials. There are associations like the NSA and SRCA who do their best to promote, but as a part of these associations, they are a far cry from widespread message.

Another main issue with slate is money. American don’t stay in their homes for decades any longer. It’s commonplace to move about. When that decision comes to replace or repair your slate roof for 50k or spend half that on shingles, it’s a financial decision. Add that new installations are not as prevalent because structures are not being built to support slate and it’s apparent why slate is not on the way up. Business and reputation is also being lost to millions of dollar
marketing campaigns of a synthetic product that calls itself slate if the industry didn’t have enough to overcome. Why Synthetic Slate Is Destroying an Industry.

Tell Us What You Think

This is an ongoing issue. Groups get together and talk, but at the end of the day, there are hurdles that a group of like minded people need to solve. If you’re passionate about slate, share your thoughts in this post and rally the troops. Or give ideas of what is happening in this industry. The more buzz created, the more detailed we can get to solving the problem.

Combating Each Level

The issues of slate awareness exists on many levels.

Architects – Educating so that they know slate exists and they consider it over synthetics.

Contractors – Roofers who visit slate repairs and tell the home owners that “slate doesn’t exist” and they will have to re-roof with asphalt shingles is commonplace. When a roofer doesn’t know how to do the job, they will push into the direction that will make them money.

Distributors – Distributors like ABC and Beacon are in business to make money. When billion dollar companies get together, they push the products that make them money. Consider most distributors don’t stock slate, they don’t push slate.

Homeowners – A roof to a homeowner is an expensive problem. If they don’t understand what they have, they will choose the least expensive option.
