Chippings

[The Medway Handyman]

Trying to find those very small white chippings used on flat roofs, but Google searching for chippings only brings up gravel suppliers.

Do they have a specific name?

[The Natural Philosopher]

IIRC they are granite chippings.

There may indeed be a special name for them..

================================== I don't know a specific name for them (other than 'marble chippings') but we used to get them from a 'Monumental Mason' - i.e. grave headstone maker. They're the waste chippings from marble headstones etc.

Try local:

for 'Monumental Mason / Stonemason'

Try Asphaltic. They are specialist roofing suppliers they might stock them.

Could be Skye Marble - see various examples here

I thought that they were limestone, light in colour so as to reduce the heat input onto a flat roof.

My local builders merchants carried some in stock and there is about 1/2 bag on my drive right now.

The white ones certainly make your garden look like a cemetery

Chippings or Not ?

I'd paint it a light colour with something and forget the chippings. Makes it easy to see faults in the roofing material, and you won't damage the material by walking across it and causing punctures.

BTW IANA Roofer, so what do I know....

These chippings are called " Canterbury Spar", and I am reliably informed that they are small pieces of flint that have been baked so that the flint starts to delaminate, which makes them more able to hold a reservoir of water, which helps to keep the roofing felt cool. I'm confident that they are available around Canterbury and Chartham. HTH!

That's probably correct for Kent. In most places there would likely be a local equivalent. In this area it's more likely to be limestone chippings.

[Dave Plowman (News)]

The ones on my flat roof ain't granite. Something much softer like marble or chalk. Perhaps they are simply locally sourced?
