Instead of faffing arou7nd with skylights and flashing
why cant I use glass or perspex slates
the same size as the existing slates?

Could I cut down scrap car windows?

Has this already been done, with success or failure?

One of the Grand Designs (the huge pit under the stone barn) used them
with solar heating

Could I cut down scrap car windows?

Good luck required with that, I should think ...

How will you clean between the glass"slates" when they fill up with
crap?

It works. The glass cracks so use wired glass - the result looks
crappy from the inside. This could be fixed with diffusing secondary
glazing. You may get damp in there though.

Nope they are toughened and will shatter into lots of little bits.

Guess you could use glass but someone has already mentioned how one
would clean between them when the algae builds up. Wonder if copper
nails and a copper wire along the ridge would keep the algae at bay?

They are available from roofing suppliers for matching several common
concrete tile profiles. They may do slate versions too, or you could
take a slate along to a glazier and have some glass slates made up the
same size, and I doubt that would cost much. You'll probably want the
weight of glass to stop them flapping in the wind (don't have them
made too thin). Also, you'll need to cut though any lining under the
slates to let the light through.

Examine a greenhouse roof. After three years

Form your own conclusion.

Glass tiles were regularly used on old agricultural buildings to allow
some light into loft spaces

Is this your house or an (unheated) outbuilding?

Remember how slates are laid in overlap - the result is 2 slates
thick. So you will have a crud-collection space between the layers.

Remember also that wind and rain blows up under the slates,and into
the space below - or you have a roofing felt.

You'll also have the exposed roofing battens running across you glass
slates as well.

You can get glass pantiles, but I've never seen them used in an
inhabited space - just lofts and barns, and they let a bit of light
through at best.

Car windows are toughened glass and cannot be cut successfully.

Yes, it'd be worse than a greenhouse cos of the gap,
it would go green, and hold dampness except on days like this,
and be impossible to clean.

And still the battens will cross the opening.

We had a pane of glass (about 18" by 12") inserted instead of a number
of slates to make a skylight at our house in Nottingham. Unfortunately
the people who had done it appear to have inserted it without going on
the roof and relied on friction rather than some copper straps - hence
it regularly slid down!

After a while I made a small skylight myself from a wooden frame and
self adhesive flashing strip and the "window" dropped over the frame.

Not impossible in the least. You'd need a thin flat cleaning device,
just poke it between the glass slates from the inside. But its never
going to look nice & clean.

If they are near enough the right size they won't need cutting, just
cut the other slate to fit.

IIRC flat side panels are sometimes laminated or were. They can be cut
witha scratch and meths in the scratch set aflame.

Whatever it would be silly not to try. Failing that glass cutters
might sell seconds and sheep ends. A thin layer of clear silicon
smeared between two sheets would give you a reinforced ply.

If you use a galss pane you must ensure no dopey druggy will stand on
it, he might get hurt and sue you.
