ROOFING'Types of roofs' means two different things: the shape of the roof (gable, hip, gambrel, mansard, flat) and the material on it (asphalt, metal, tile, slate). For most homes in Georgia and the Carolinas, that's a simple gable or hip frame covered in architectural asphalt shingles, with metal a growing second choice on the coast and in hail country.
The short version
- Shape and material are two separate choices. Shape is the frame (gable, hip, flat); material is the covering (shingle, metal, tile).
- Gable roofs are cheapest and most common here. Hip roofs cost more but handle wind far better, which matters on the coast.
- Most Southeast homes wear architectural asphalt shingles ($450–$700 a square), with metal ($900–$1,600) gaining ground in hail and salt country.
- Don't overlook vents. A ridge-and-soffit combo pulls our attic heat and humidity out, and that airflow can add years to the roof above it.
Two things people mean by 'type of roof'
Ask two people about roof types and you'll get two different answers. One's talking about the shape of the thing, the frame and slopes: gable, hip, that sort of word. The other means what it's covered in: asphalt, metal, tile. Both are real, and they're independent. A gable roof can wear shingles or metal. A hip roof can wear tile.
So this guide splits them. Shapes first, because that's the part you can't easily change, then materials, then the vents that quietly keep either one alive in our climate.
Roof shapes, at a glance
The five you'll actually run into on Southern homes, and what each one means where we live.
| Shape | What it is | What to know in the Southeast |
|---|---|---|
| Gable | Two slopes meeting at a ridge, a classic triangle | Cheap and sheds our downpours well; wind can catch the flat gable end |
| Hip | All four sides slope down to the walls | Best wind resistance, a real plus near the coast; costs more to frame |
| Gambrel | Barn shape, two slopes per side | Adds attic space; the steep lower slope catches wind |
| Mansard | Steep four-sided lower slope, French style | Rare here; adds a floor but is complex and pricey to maintain |
| Flat / low-slope | Nearly level, sealed with a membrane | For porches and additions; must drain fast or ponding water kills it |
Gable and hip cover the overwhelming majority of houses here. The other three show up on specific styles and additions, not on your average subdivision home.
Gable vs hip: the choice that matters most here
If you only learn two roof shapes, learn these. A gable roof is the simple triangle most of us drew as kids: two slopes meeting at a ridge, open gable ends on the sides. It's cheap to build, sheds our afternoon downpours easily, and gives you attic room. The weakness is that open gable end. In a strong straight-line wind it acts like a sail.
A hip roof slopes on all four sides down to the walls. No flat end for wind to grab, which makes it markedly more storm-resistant. It costs more to frame and gives you a bit less attic space, but here's my opinion: if you're building or reroofing near the coast, from Charleston through the Lowcountry, the hip roof is worth the money. Wind is the thing that takes roofs off down there, and the hip shape fights it before a single shingle does.
From Mount Pleasant to Savannah's Historic District, wind is the roof's enemy, not cold. That's why you see so many hip roofs and wind-rated systems near the water. And if you're in a historic district, remember the local Historic Review Board may dictate what shape and material you're even allowed to install. Check with them before you fall in love with a standing-seam metal roof they'll never approve.
Roofing materials, quickly
The covering is the other half of 'roof type.' Here's the short version, with the per-square costs that decide most of it.
| Material | Per square | Lasts | Best for |
|---|---|---|---|
| Asphalt shingle | $350–$700 | 15–30 yrs | Most homes, from budget 3-tab to standard architectural |
| Metal | $900–$1,600 | 40–70 yrs | Hail country, the coast, long-term owners |
| Tile | $1,000–$2,000 | 50+ yrs | Heat and Mediterranean-style homes |
| Slate | $1,500–$3,000 | 75–100+ yrs | Premium and historic homes |
Shingles cover the vast majority of roofs here for a reason: cost and simplicity. Dig into any one on its own page, like metal or asphalt shingle, or price your own on the roof calculator.
Types of roof vents, and why they matter in our heat
Vents are the part of the roof nobody thinks about until the attic hits 140°F and the AC can't keep up. Ventilation lets that heat and moisture escape, and in our climate that airflow is what keeps a roof from cooking itself from underneath. The common types:
- Ridge vents. Run along the peak, hidden under the cap shingles. The best all-around choice, and nearly invisible.
- Soffit vents. Sit under the eaves and pull cool air in. They only work paired with an exhaust vent up top.
- Gable vents. The louvered triangles in the gable end. Simple, but they don't move as much air as a ridge-and-soffit setup.
- Box (static) vents. Low squares dotted near the ridge. Cheap and passive.
- Powered and turbine vents. Fans or spinning caps that force air out. They move the most air but add cost and, sometimes, noise.
The setup I'd point most homeowners to is a continuous ridge vent paired with soffit vents. Cool air enters low at the eaves, hot air rises and exits at the peak, and the attic breathes on its own with no motor to fail. In a Piedmont summer that airflow can drop attic temps by 20 to 40 degrees, which eases your AC bill and slows the heat damage that ages shingles early.
What actually suits a Southeast home
Put it all together and the typical Georgia or Carolina answer is straightforward: a gable or hip frame, architectural asphalt shingles, and a ridge-and-soffit vent system to fight the heat. That covers the vast majority of homes from metro Atlanta to the Triangle, and it does the job well.
Where I would break from the default: near the coast, lean hip-roofed and give metal a serious look for the wind and salt resistance. In deep hail country inland, metal earns its price too. Everywhere else, quality architectural shingles are the value pick. Compare the numbers by material on the architectural shingle and metal pages, or price your own roof on the calculator before anyone asks for your number.
