Louisville's roof replacement conversation changed forever on December 30, 2021. The Marshall Fire destroyed 553 homes and damaged 45 others in this Boulder County city of 21,000 residents. Colorado's most destructive wildfire proved that suburban roofs are the first line of defense against ember-driven fire. Louisville now operates under 2024 ICC codes with a 115 mph wind speed rating and enhanced fire resistance standards. A roof replacement in Louisville requires materials that protect against both wildfire from the grasslands to the west and hail from the Front Range corridor to the east. No other city in this series demands dual-threat protection.
