Concrete and clay roofing tiles are beautiful, durable, and have proven long-term performance. Tile roofing can last the life of a structure when maintained correctly. Although concrete and clay tiles have similar aesthetic features, they have inherent differences that you should explore before choosing either material. Therefore, check out the following differentiating factors before selecting the best roofing material for your home.

Material Weight

Weight is one of the most significant factors to consider when choosing between concrete and clay tiles. Concrete tiles are heavier than clay tiles. Therefore, when installing a roof, you need to assess the strength of your roof. If you opt for concrete tiles, you have to strengthen the roof framing and underlay, so they can withstand the extra weight. Failure to do so can lead to premature roof failure.

If you are replacing an existing roof, your material options may be limited to its weight limits. For a standard roofing structure, clay tiles would be the best choice. Since they are lighter, they can work well with a roof that's not designed to handle heavy materials. If you choose concrete tiles, you must reinforce the roofing beforehand to prevent structural issues down the road.

Moisture Resistance

Concrete tiles have a higher moisture absorption rate than clay tiles. Therefore, when it rains, water is more likely to infiltrate a concrete tile roof. The moisture may not damage the concrete, but once it penetrates the underlay, it may cause structural damage. You must apply a topical sealant on the tiles to prevent moisture absorption. When used correctly, the sealant can create a waterproof barrier that will protect your roof against water damage.

Unfortunately, sealants gradually wear due to UV damage, hail, and other forms of inclement weather. If you don't reapply them, your roof will absorb water. Therefore, if moisture infiltration is a major concern, you should choose clay roofing tiles. With a low water absorption rate, clay tiles can better protect your roof's underlay from moisture damage.

Resilience to Inclement Weather

Inclement weather is a leading cause of premature roof deterioration. Hailstorms, ice storms, snow, heavy rainfall, and extreme solar heat can break down roofing materials and shorten their lifespan. Both concrete and clay tiles hold up impressively to inclement weather. 

However, clay tiles don't hold up well to freezing temperatures. Freeze-thaw cycles can cause clay tiles to shatter and crack, necessitating immediate repairs to prevent moisture damage. Concrete tiles can resist extreme winter temperatures and freeze-thaw cycles. Therefore, they are more suited to areas that experience brutal winter. Clay tiles work better in warm climates with fewer episodes of inclement weather.

Consider the above factors when choosing between concrete and clay tiles for residential roofing. For professional input, consult a roofing contractor.
