Roofing Material Identification

Recommended Posts

Anyone ever see this roofing material before? It's like a terra cotta tile.

Looks like they were produced in Chicago and would have been installed in 1956. Anyone know of a factory that still produces these?

It's called English Interlocking Tile. I don't know of an exact match being manufactured today.

Mortenson Roofing is well known in the historic preservation world for their extensive collection of salvaged roofing tiles. I'd bet they could tell you if there are new or used tiles to match. http://www.mortensonroofing.com/

Bill,

There is roofing tar on the corner seams as shown in picture. What is the detail that goes into this area to make it water tight? I didn't see any signs of leaks in the attic around this area.

Shouldn't this area have some kind of cap?

Manufacturers of interlocking tiles have accessories to detail transitions and terminations. There would have been a hip cap tile available. On that particular roof, it would likely have been a hip roll tile to match the ridge roll.

Like the ridge, the hips aren't subject to collected water running down the field of the roof. A majority of hipped slate roofs don't have hip caps. The rest have sheet metal caps.

I am sure SOMEONE has seen that type of roof material before because someone had to make it.
