Why Southern Homes Cannot Handle Winter Weather
Georgia's building code does not mandate the heavy pipe insulation required in northern states. This creates a massive architectural vulnerability.
Builders in Atlanta design homes for extreme summer heat and humidity management. Pipes often run through completely unheated spaces like garages, attics, and crawl spaces. A home built in Minnesota features heavily insulated plumbing. A comparable home in Marietta features almost none.
Atlanta averages one to three hard freeze events every winter, with temperatures below 28°F for several consecutive hours. Because local pipes lack basic insulation, they absorb this freezing temperature immediately.
