When it comes to selecting natural roofing slate for prestigious architectural projects, the choice of supplier can make all the difference between a successful installation and potential long-term issues. At SSQ, we’ve established ourselves as leading slate distributors through our unique approach to sourcing and quality control.
What sets premium slate distributors apart from standard suppliers?
The key distinction lies in direct quarry relationships. While many slate suppliers source from multiple quarries without established connections, SSQ maintains exclusive partnerships with select quarries in Spain and owns a quarry in Argentina, ensuring unprecedented control over quality and supply.
The importance of consistency in natural slate supply
For architects and specifiers, consistency is paramount. Our direct quarry access ensures that whether you’re ordering Spanish slate or our distinctive Riverstone phyllite, you’ll receive the same exceptional quality across every order, from sample to bulk delivery.
Understanding the risks of poor-quality slate
Poor-quality slate can compromise the integrity and aesthetics of your entire roofing project and lead to serious issues. Oxidation can create unsightly rust stains, while leaching often leads to white streaking across your roof’s surface. Most critically, delamination can cause slate to split and deteriorate, risking structural damage. Through our direct quarry relationships, SSQ’s rigorous quality control process effectively eliminates these common issues, ensuring long-term performance and appearance.
