The state's susceptibility to severe weather events, including hailstorms and high winds, necessitates robust roofing systems designed for impact resistance and superior wind uplift protection. Illinois building codes, while generally standardized, may have specific local amendments, particularly in larger municipalities like Chicago, requiring careful attention to detail during the permitting and inspection phases.
