Concrete shingles

Have a concrete shingle roof. Found 3 cracked/broken shingles and want to replace them. Anybody know where I would go to buy them? I’m in Rancho cucamonga which is about 45 m east of LA. Thanx

no help?

see if the tiles have a name on the back of them.
then search the name and roof tiles online,
( pioneer roof tiles)
you can probably by them online.
