Lately it seems that people are quick to endorse synthetic slate roofing materials without much history to support their approval. Some people rave that synthetic slate is much cheaper than natural slate, lighter, more durable, has a 50+ year warranty and it’s typically recycled. But it seems that few people mention its fading qualities and the fact that the majority of these products have only been around for about 20 years. In my opinion, these materials are simply too new to commit to a “life span.”
If you have a natural slate roof, you should really try to stick to the real thing no matter how tempting a faux product might seem. This is especially true when maintaining the historical integrity of your home is a priority.
