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?

Yes, but getting it past the BCO will be a problem.

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.

Well, if you're employing some damn fool that's using plain old steel
nails for this purpose, you can't really blame the material the 'slates'
are made of.

If they are saving costs by using composition slates, it is not very
likely they would pay the extra for copper nails.

Synthetic slates are a thing...

Artificial slates have been popular round here for many years. Seem to
last pretty well. Slightly easier to fit as less skill needed to cut them
where needed.

Done by a cowboy. Artificial slates should use copper nails.

Lots and lots round here using artificial slates. Many date from when the
council were dishing out grants towards such things - about the '80s. And
can't say I've noticed any slipping. But of course the council insisted on
it being done properly, before parting with the money.
One or two have discoloured badly. But most look as good as new. Likely
different makes.

They are very popular amongst dodgy roofers who know that original
victorian slates in good nick can be resold for more than the cost
of new synthetic ones.

Plenty of unsuspecting homeowners have been caught out this way,
and I suspect some don't even know that their original slates
could have been re-used on their own house.

Repairing an original slate roof using matching tiles can be very costly.
You may not even be able to find a decent match. Early slate roofs had no
felt, so have to be stripped totally. You may also want to add decent
controlled ventilation for the roof - especially where insulation has been
added.

The Victorian houses around here were build 125+ years ago for working
men and their families. The slates used weren't of the quality you'd
expect to find on a Gentleman's London residence[1]. After 125+ years a
large proportion of most which remain are delaminating, cracked, have
enlarged nail holes etc. I saw how many slates were sold on for re-use
when our roof was replaced c10 years ago. It was a quarter at most.

[1] from the quotes we got foir "real" slates, there seems today to
still be different standards within BS EN 12326 with different lifetimes

When I had the roof replaced on my 1905 property many of the slates were
in a very poor condition with delamination edges crumbling. Only about
a third were salvaged for re-use and even those probably only suitable
for patching up an older roof where matching of the material was important.

True. But also means they'd have little resale value.

The slate must be of better quality round here. A friend's 1880s house
is still on its original slates (bar a few), and they're in fine shape.
The tingles are slowly increasing though.

My brothers house in the NE of Scotland still has most of the original
slates. And it's closer to 200 than 100 years old. But the roof
construction is different, with tongue and groove boarding under the
slates - presumably to carry the weight of snow.

Tongue and groove was common 200 years ago, both my parents (Hertfordshire) and our house (Warwickshire) of a similar period have it.

They'd obviously started building down to a price round here in Victorian
days. You could see sky through the roof at the right angle. ;-)
