Hi,

Is there no alternative to slates or tiles when it's time for a new roof?
Surely there must be a lighter and cheaper synthetic option nowadays?

Although the advantage of traditional materials is that you have a very
good idea of their expected life.


One of the shops at the end of my street was roofed with some kind of
composite slate look-a-like material. Although the same size as a slate
they were around 50 to 75% of the weight. The roof looked good when
first done but 15 years later it looked if the roof had been installed
50+ years ago. While the "slates" were still in good condition the nails
used had presumably rusted away and many slates were slipping/dislodged.

The life expectancy of a roof is dependent on the roofing material and
the standard of workmanship installing it.
