Advantages and problems with synthetic slate roofs
Synthetic slate is lighter, more impact resistant, and costs less than natural slate but typically doesn't last as long and may not provide a perfect replica for an authentic slate roof. Common problems with synthetic slate roofs include tiles curling or cracking.
What is synthetic slate roofing?
Synthetic slate roofing is made from plastic or rubber that is injection molded and formed to look like natural slate. Synthetic slate shingles simulate the look of authentic slate but at a fraction of the weight and cost. Many synthetic shingles are made with high-quality recycled materials.
How long does a synthetic slate roof last?
A synthetic slate roof lasts 30 to 50 years, depending on if it is made from plastic or rubber. Composite plastic slate typically lasts longer than rubber slate.
How do synthetic slate roofs perform in bad weather?
Synthetic slate is rated to withstand winds of to 110 to 130 mph, depending on the brand. Most brands come with a Class 4 impact rating – the highest available – and can withstand 2" hail. Slate's smooth surface also allows ice and snow to slide off before causing damage.
