In this article, our roofing experts explain different types of sloped and flat roofs, and how long a roof lasts in your state.

In Georgia, your house will experience a humid subtropical climate, which means there will be hot, humid summers, mild winters with little snowfall, and the springtime will be unpredictable- often a mix of heavy showers, warm days, and cold, breezy nights.

This is important because you must know what type of roof can stand strong in these weather conditions for years to come! Here are the top 5 sloped roofs that are common in Georgia.

Top 5 Sloped Roofs

Roofing material is one of the most important factors that will affect the longevity of a roof. All over the US, you will mostly find shingle, metal, slate, tile, and wood shake roofs.

Whenever homeowners ask us ‘how long does a roof last, we begin with asphalt shingle roofs because nearly 80% of US homes have this roofing material on them.

How Long Do Shingle Roofs Last?

Asphalt shingles are affordable, resistant to fire and water, and can last for 15-30 years, depending on their thickness and style. Shingle roofs are also relatively lightweight, easy to install, and they are available in hundreds of shades!

3-Tab asphalt shingles

While this traditional shingle style demands the least initial investment, it also has the shortest expected lifespan and needs regular maintenance. A 3-tab shingle roof can last anywhere from 15-20 years.

Architectural Or Dimensional Shingles

Architectural shingles are an upgrade to the 3-tab shingles. They are thicker and offer beautiful 3D looks, providing extra longevity and protection for homes in Georgia. Roofs with architectural shingles have an average lifespan of 25-30 years.

In Georgia, homeowners often have one common question: How long does a roof last if it’s made of metal? That’s because metal roofs fall under cool roofs, and they are best for hot and humid climates.

How Long Do Metal Roofs Last?

Metal roofs may initially look expensive, but they can be of great value due to their appealing style, incredible durability, and energy-saving ability. Metal roofs can last from 50 to 70 years, especially in areas where winds may often blow over 30mph, such as in Georgia. The prices and durability depend on the metal and installation technique you choose.

  • Standing seam metal roofs have hidden fasteners and a flexible installation technique, which enables maximum protection from heat and moisture damage. These roofs may last for over 50 years in Georgia. Screwed-down metal roofs have visible screws or nails, and they are suitable for colder or rainy regions.
  • The most common metal roofs are aluminum, stainless steel, and copper. They may be expensive to install, but they have a record of staying solid and beautiful for over 70 years! For a fresh look and enhanced protection, you can repaint them anytime. The most affordable metal roof is a steel roof coated with excellent waterproof paint, and these can last for up to 30 years.

How Long Do Tile Roofs Last In Georgia?

Like metal roofs, clay tile roofs can last up to 50 years. If you take good care of your tile roofing system, you can extend the lifespan by a few more years. Tile roofs are quite heavy, and they are an excellent choice for hurricane-prone areas. Moreover, clay tile is also resistant to fire, water, wind, ice, mold, and termites.

These are the top three options for residential roofs in Georgia. The last two roofing materials, slate and wood shakes, are typically suitable for areas with long, burning summers and snowy winters.

Slate Roof

Slate is a natural metamorphic rock, and that’s precisely what slate roofs are made of. Metamorphic rock is a result of heat transformation over centuries, so it is the best option for climates with hot temperatures. These are luxurious roofs, prevailing since ancient times, and they can last for a hundred years on your home without needing any repairs.

Wood Shake Roofs 

Wood shake roofs have been diminishing over the past few years, mainly because the world now offers many more durable and beautiful roofing options for homes. But if you are among homeowners who want to enjoy the luxurious, rustic look, you would undoubtedly want to know how long does a roof last if it’s made of natural cedarwood shakes. You can expect such a roof to last up to 40 years after proper maintenance in Georgia. Wood is an excellent insulator, which means shakes roof can keep your home from cooling or heating up too much. These roofs can also resist very high wind speeds.

Apart from sloped roofs, some homeowners in Georgia also prefer flat roofs for leisure space and green roofing options. So the next part of this article specifies how long does a flat roof last.

How Long Does The Top 3 Flat Roofs Last?

Flat roofs are relatively less durable than sloped roofs, where most flat roofs have a lifespan of about 15 to 25 years. It largely depends on how you use and maintain a flat roof. The top three flat roofs in Georgia are TPO, EPDM, and bitumen.


EPDM roofs can last up to 20 years with proper maintenance. These are one of the oldest classes of rubber roofs, and they provide excellent insulating properties. Georgia often gets hail, and EPDM roofs can handle the stones pretty well.


TPO roofs are a modern, energy-efficient option, and they have evolved quite a bit over the last few years. These roofs can also last up to 20 years, offering maximum protection from UV rays and chemicals. It can keep your building cooler, and these roofs can even lower energy bills while resisting chemicals and pollution.

Modified Bitumen

Modified Bitumen flat roofs can generally last up to 30 years. Using them regularly to walk, maintain a roof garden, or conduct similar activities, may reduce their lifespan by 5-10 years. Proper protective coatings and roof structures allow you to convert your flat roofs into a perfect recreational space.

Outside of the roofing material, some other crucial factors can also determine how long a roof lasts. For example, the installation quality, maintenance, attic ventilation, and insulation can all affect the lifespan of your roof. That’s why it’s always wise to consult reliable, local roofing professionals about all your needs and budget.
