Roof Shapes and Common Leaks in Commercial Roofing Atlanta, GA
If you own or manage a commercial building, roof problems can be a real headache, especially here in the Southeast. In this post, we’re breaking down the most common roof shapes and what typically causes leaks, with a focus on commercial roofing Atlanta, GA. Whether you're a property manager or business owner, understanding these basics can help you catch issues early and avoid costly repairs down the line.
Roof Shapes in Southeast Commercial Roofing
Roof shapes vary depending on regional climate. In Atlanta, GA and other parts of the Southeast, roof design is influenced by rainfall, wind conditions, and temperature extremes.
The pitch of a roof, or its steepness, is defined by its rise over a 12” span. Generally, a 3/12 or lower pitch is considered low-slope (common in commercial buildings), while an 8/12 or more is steep.
Common Commercial Roof Shapes in Georgia:
1. Gable
Seen on steep roofs, a gable creates the triangular wall formed by two roof pitches. While less common in commercial roofing Atlanta GA, some older industrial buildings still use this shape.
2. Flat Roof
Flat roofs dominate commercial roofing in Georgia, especially in Atlanta. They have a slight slope to allow water runoff and are often constructed using BUR or modified bitumen. This design is ideal for solar panels, HVAC equipment, and easy maintenance.
3. Hip Roof
Hip roofs slope on all four sides and are resistant to wind damage. They are occasionally used in commercial construction when aesthetics and structural durability are key.
4. Shed Roof (Skillion)
This single-slope roof design is becoming popular for modern commercial buildings in the Southeast, especially in warehouses and additions.
5. Gambrel Roof
This dual-slope design allows for expanded upper-level space and is more commonly seen in barns or storage facilities.
6. Mansard Roof
Used in historical or French-influenced architecture, this shape adds livable space without increasing overall height—rare but notable in mixed-use buildings in Atlanta.
Common Roof Leaks in Commercial Roofing Atlanta, GA
Leaks in commercial roofing Atlanta, GA are a frequent concern. From high humidity to summer storms, your roof endures a lot. Here’s how to spot and fix some of the most common issues:
Drain Leaks
Improper drain maintenance causes leaks often mistaken for membrane failure.
Fix:
- Inspect drain assemblies.
- Replace corroded parts.
- Seal waterproof layers properly.

Neglected Roofing Decks

Failed flashing around vents, edges, and chimneys leads to water intrusion. Foot traffic and equipment movement can cause additional membrane damage.
Fix:

Coatings Extend Roof Life
When applied correctly, roof coatings offer excellent protection from UV, water, and wind damage in Georgia’s climate. However, they require a structurally sound surface—don’t use coatings to mask underlying issues.
