Heavy rain and moisture: Frequent rain events saturate roof structures, making high-grade synthetic underlayment essential to prevent rot.
Intense UV exposure: Prolonged sun and high heat speed up asphalt degradation, causing shingles to dry, crack, and lose protective granules.
High wind hazards: Strong storm gusts can lift standard shingles, requiring wind-rated materials and double-fastening.
Convective hail storms: Seasonal hail impact bruises shingle mats, compromising their water-shedding capability.
Algae and mold growth: High local humidity promotes algae streaks, necessitating copper-granule shingles.
