Tips

  • Louisville's Fire Hardening Code requires Class A roof coverings (per ASTM E108/UL 790) citywide, not only inside a mapped Wildland-Urban Interface zone. Every re-roof within city limits must comply, so price Class A materials from the start.
  • Gutters must be metal with gutter guards under the Fire Hardening Code — vinyl gutters are not permitted on a re-roof project that also touches gutters.
