How long does a slate roof that uses SlateSpacer™ last?
The evidence predicts that SlateSpacer™ will extend roofing slate life by many decades, in the case of high quality slate, and by many years, in the case of low quality slate. This is because SlateSpacer™ lets slates dry 8X faster, resulting in a dramatic reduction in the time during which aging processes can occur. In the simplest terms: The processes that age slate require water; slate traps water (as do other overlapped roofs), and SlateSpacer™ frees trapped water.* * Drying tests, the archeological record, examination of old slates and a modern understanding of the processes that age stone — all predict substantial lengthening of slate life.
