How is hail damage to modified bitumen roofs applied in asphalt or bitumen modification processes?

Hail damage to modified bitumen roofs occurs when hailstones impact the surface, causing punctures, tears, or surface granule loss. During asphalt or bitumen modification processes, additives like SBS (styrene-butadiene-styrene) or APP (atactic polypropylene) enhance flexibility and durability. However, extreme hail can exceed these materials’ resilience, leading to compromised waterproofing and insulation. Regular inspections and maintenance are essential to identify and repair hail damage promptly, ensuring the roof’s longevity and performance.
