Orlando receives an average of 51 inches of rain annually, with most precipitation falling during intense afternoon thunderstorms between June and September. These storms generate microbursts with wind speeds exceeding 70 mph and produce hail from rapidly rising air currents. The combination of high humidity, intense UV radiation, and temperature swings from 50 to 98 degrees creates harsh conditions for roofing materials. Standard shingles degrade quickly under this constant stress. Class 4 impact resistant shingles use UV inhibitors and modified asphalt that maintains flexibility through Orlando's temperature extremes. The investment in UL 2218 Class 4 shingles makes sense when you consider replacement costs for standard roofs that fail after 12 to 15 years versus impact rated materials lasting 25 to 30 years in the same climate.
Orange County building inspectors verify compliance with Florida Building Code Section 1507 for steep-slope roofing applications.
