How does the building position affect glare?
The position of most commercial and industrial roofs mitigates the likelihood of roof glare because they are often high-set with a low pitch so they are rarely seen from the ground and the surface has very little impact. Roof glare complaints are commonly associated with mirrored sunlight causing a significant impact on visual amenity. In most Australian locations the path of the sun throughout the year is to the north of buildings. This means most of the mirrored reflection from a roof travels toward the south and above the roof. Therefore the area of concern for a commercial or industrial building is when a neighbouring residential area is directly to the south and above, overlooking the roof. In this instance a high gloss or bare metallic roof may not be appropriate.
