Roofing Sand
Sand is used in roofing in several ways, primarily to improve durability, weather resistance, and aesthetics. Here are the main applications:
1. ASPHALT SHINGLES
Many asphalt shingles have a top coating of mineral granules, including sand, to provide UV protection, fire resistance, and durability. The sand helps prevent degradation from sunlight and weather exposure.
2. ROOF COATINGS
Sand is sometimes added to liquid roof coatings (such as acrylic, silicone, or elastomeric coatings) to enhance traction, durability, and impact resistance.
3. BALLASTED ROOFING SYSTEMS
While less significant than physical and biological processes, sand can adsorb some dissolved contaminants (like iron or manganese), especially when coated with oxides or combined with other filter media..
4. CONCRETE AND CLAY ROOFING TILES
In some flat or low-slope roofing systems, sand or gravel is used as ballast to help hold down roofing membranes, protecting them from wind uplift and UV exposure.
5. BUILT-UP ROOFING (BUR) SYSTEMS
These traditional flat roofing systems use layers of bitumen and reinforcing fabrics, sometimes incorporating sand or fine aggregates for additional weather resistance.
