   They're know as T-locks in my neck of the woods. The roofing company Sheriff-Goslin (sp) in Kalamazoo Michigan uses them. They might be able to help find a supplier. They install in Michigan and Ohio. I'll have to look for their contact number

   T-Locks are a completely different animalTjhe diamond shaped pattern used to be laid up by three different shingle types that I know of. The most common I saw were Asbestos which are definitely no longer in production. There was also a strip shingle, the bottom of which was cut in a zig-zag pattern that you laid to create a bit more of an octogonal or sexagonal effect. Then the origianl slate ones thatthe asbestos were modeled after.Ther are modern re-creations copying these. I just got a flyer in the mail the other day - but threw it out.

    Piffen,

   there is a 4 th type

   as previously mentioned by jeremy, I believe.

   Sherrif Goslin markets an asphalt shingle kind of similar to a Tlock in application----probably more accurate to call it a single coverage interlocking shingle.

   each diamond is approx. 12"x12" and this type of shingle---in my area(ohio) is almost exclusively used as a layover application---usually a 3rd layer installation.

   I believe in this area Sherrif Goslin stocks this themselves and it will NOT be available in the open market from an ordinary supplier. I strongly doubt that sherrif Goslin will sell a few of these for repairs either.

   Personally---I don't like them on most houses------- but they do look appropriate on a period house---maybe a 1880's-1890's mansard style ( 2nd  Empire?)

   anyhow---sherrif Goslin is definitely who ya wanna contact if you really want these----I have never seen anybody else handle these.

   Stephen.

   No, they are not the same as T-Locks.

   Both suck anyway, but there is a difference.

   I ripped the diamonds off of my barn and put metal panels up. I still find chunks of diamonds in the yard though, and I replaced that roof 7 years ago.

   Can't help with a source. I haven't seen them anywhere.

   Don't know if this is what you are looking for but my father-in-law condidered these at one point. He opted for a more conventional shingle in the end.
