Drawbacks of Clay and Concrete Roofs in Atlanta

The choice of roofing materials can significantly impact the aesthetics, durability, and overall performance of your home’s roof. In Atlanta, a city known for its diverse climate and architectural styles, selecting suitable roofing materials is crucial. 

Continue reading as we discuss the drawbacks of clay and concrete tile roofs and the benefits of opting for asphalt shingles or metal roofing materials.

The Drawbacks of Clay Roofs for Residential Homes in Atlanta

For homeowners in Atlanta, Georgia, considering a clay tile roof comes with its own set of drawbacks that must be carefully weighed against its benefits.

High Initial Investment: One of the most significant drawbacks of clay tile roofs is their high initial cost. Compared to asphalt shingle roofs, which are commonly used in residential properties, clay tiles can be three to four times as expensive per square foot. This hefty price tag can be a deterrent for homeowners on a budget or those looking for a more cost-effective roofing solution.

Structural Requirements: Installing clay tiles requires specific structural considerations. These tiles are best suited for roofs with steep slopes, such as gable roofs, with a minimum allowable slope of 2 1/2 to 12 inches according to the International Code Council. This means that homeowners with flat or low-sloped roofs may not be able to install clay tiles without significant modifications to their roof structure, adding to the overall cost and complexity of the project.

Regular Maintenance: Proper maintenance is essential to ensuring the longevity of a clay tile roof. Over time, dust, organic matter, and debris can accumulate on the roof’s surface, providing a breeding ground for algae, moss, and mildew—particularly in Atlanta’s humid climate. This buildup not only detracts from the aesthetic appeal of the roof but can also compromise its structural integrity over time. Regular cleaning is necessary to prevent these issues, but due to the safety concerns associated with working on a clay roof, it’s best to hire a professional for this task.

The Drawbacks of Concrete Roofs for Residential Homes in Atlanta

While some drawbacks of concrete roofs overlap with those of clay roofs, concrete roofs present some unique concerns.

Physical Appearance: One of the first things homeowners notice about concrete roofs is their initial aesthetic appeal. However, over time, the patterns, paints, and overall design can fade due to exposure to harsh weather conditions prevalent in Atlanta. High heat, heavy rain, and strong winds can accelerate the deterioration of concrete tiles, leaving the roof looking dull and unattractive. While repainting is an option, it adds to the maintenance workload and incurs additional costs, making it a less desirable solution.

Water Absorption: Porous materials like concrete roofing tiles are prone to water absorption if not properly treated and weatherproofed. Without adequate sealants or treatment, moisture from rain, foliage, and air can penetrate the material, resulting in issues like mold, mildew, and potential deterioration of the tiles. Furthermore, water absorption adds weight to an already heavy roofing material, placing additional strain on the home’s structure and potentially causing serious structural issues over time.

Underlayment Replacement: While concrete roofing tiles are durable, the underlayment they sit upon is not. While the tiles can last up to 50 years, the underlayment typically needs replacement every 20 years. This recurring maintenance task adds to the overall cost and upkeep of concrete tile roofing, requiring homeowners to invest time and resources into replacing the underlayment periodically.
