The main body of bricks look like a stock brick i.e. Ibstock make a "Weston Red Multi Stock".
The red copings on top are a generic engineering standard with a drag face, i.e an Ibstock "Stratford Red Dragface".
They have used poor matching solids on the corners of the pillars and have likely used a similar brick to the coping reds at ground level.
The tile crease looks like it may have been done with a proper creasing tile as opposed to a standard double camber roof tile.
I don't know what mastic they used on the expansion joint but likely to be polysulphide mastic.
The tree behind the wall is a deciduous, fast growing.....only kidding!
