Natural or Man-made Roof Slate – Which Is Best
If you’re planning materials for a new roofing project or replacing an existing roof, slate is one of the best materials you can opt for due to its strength and durability. However not all slates are the same and there are both natural and man-made roof slates to consider, so which one is best?
The three things to look at when choosing a roofing material are:
Availability and price
First of all let’s look at durability. Here natural slate wins hands down. It has been formed over millions of years in harsh environments that few other materials could survive. Natural slate and Welsh slate in particular are renowned for lasting a lifetime and longer in many cases so once you install a natural slate roof, don’t expect to be replacing it again for 50 to 100 years!
By comparison man-made slate wears quicker with a predicted lifespan of about 20 years. IT is also susceptible to its colour fading over time which brings us to aesthetics. While you will find it hard to tell man-made slate from natural slate, over time you will notice the difference.
Lastly there is cost to consider. Natural slate can be three times more expensive to buy than man-made versions, but then again it lasts three times longer.
