Process of treating a synthetic shingle and shingle made thereby

A process of treating a synthetic shingle having upper and lower surfaces, in which the shingle is adapted to be mounted on a building surface with its lower surface facing the building surface and with at least a portion of the upper surface being weather-exposed, comprising the steps of:

• a) providing a synthetic shingle having an upper surface with high zones and a plurality of depressions therein;
• b) abrading at least portions of the high zones of the upper surface;
• and
• c) with the depressions in the upper surface being abraded a lesser amount than the level of abrasion of the high zones;
• d) whereby the upper surface of the shingle has different visual appearances in the abraded at least portions of the higher zones than the unabraded depressions.

A synthetic shingle having upper and lower surfaces, in which the shingle is adapted to be mounted on a building surface with its lower surface facing the building surface and with at least a portion of the upper surface being weather-exposed, wherein:

• (a) the shingle has an upper surface with high zones and a plurality of depressions therein;
• (b) with at least portions of the high zones of the upper surface having abrasions therein;
• (c) with the depressions in the upper surface being free of abrasions therein;
• (d) whereby the upper surface of the shingle has different visual appearances in the at least portions of the higher zones having abrasions therein than in the depressions that are free of abrasions therein.
