Which of these adds the most to fire resistance in low-slope roofing membranes?

Flat roof design
Solar panel installation
Aggregate or mineral granule surfacing
Graffiti protection coating

The correct answer is: Aggregate or mineral granule surfacing

The correct choice is indeed the addition of aggregate or mineral granule surfacing to low-slope roofing membranes. This type of surfacing plays a crucial role in enhancing fire resistance. The granular material acts as a protective layer that not only helps to reflect UV rays but also provides a measure of protection against heat and flames. These granules can contribute to a Class A fire rating, which is the highest applicable rating for roofing materials, denoting that they have low susceptibility to fire originating from external sources. Other options do not contribute as significantly to fire resistance. A flat roof design does not influence fire resistance directly; its effectiveness is more related to water drainage and structural considerations. Solar panel installation can provide energy benefits but does not inherently improve the fire resistance of the roofing membrane. Lastly, graffiti protection coatings serve a different purpose—primarily for aesthetic maintenance—without contributing meaningful protection against fire hazards.
