Climate Conditions in Key Georgia Cities
Atlanta & Surrounding Metro Areas
Atlanta and its neighboring cities, including Alpharetta, Milton, Sandy Springs, Johns Creek, Roswell, Marietta, and Cumming, experience a humid subtropical climate. Summers are long, hot, and humid with temperatures often in the upper 80s to 90s °F. Afternoon storms are common. Winters are generally mild but can bring freezing rain, sleet, and occasional light snow.
Rainfall & Storm Patterns
Metro Atlanta averages about 50 inches of rain annually, with spring and summer bringing thunderstorms and the risk of hail and strong winds. Northern areas like Cumming and Milton can see slightly cooler winters and more wind exposure due to elevation and open landscapes.
Seasonal Weather Hazards
Throughout the year, homeowners face threats like hail, falling limbs, strong winds, and even localized tornadoes, all of which can damage roofs and gutters.

How Weather Affects Your Roof
Georgia’s weather can shorten the lifespan of roofing materials if not properly maintained:
| Weather Factor | Impact on Your Roof |
| Heavy Rain & Moisture | Can cause leaks, weaken flashing around chimneys/vents, and lead to water damage inside the home. |
| Heat & UV Rays | Shingles dry out, crack, curl, or lose protective granules; roof materials age faster. |
| Humidity & Algae Growth | Moist, shaded areas promote moss, algae, and mold growth, which can stain and weaken roofing. |
| Wind & Storm Damage | Strong winds loosen shingles; falling branches or debris can puncture or damage roof surfaces. |
| Cold Snaps & Ice | Freezing conditions can create ice buildup and stress joints, leading to cracks or leaks. |
