Frequently Asked Questions

Is concrete or clay tile more popular in Arizona?

Concrete tile is more commonly installed in Arizona due to its lower cost and wider availability. It accounts for roughly 70% of tile roofs in the Phoenix metro area. However, clay tile is the preferred choice for premium homes in areas like Scottsdale, Paradise Valley, and DC Ranch.

Does concrete tile fade in Arizona sun?

Yes, concrete tiles with surface-applied color coatings can fade after 15-20 years of Arizona UV exposure. Concrete tiles with integral color (pigment mixed throughout) fade less but still show some change. Clay tile color never fades because the pigment is fired throughout the entire tile during manufacturing.

How much heavier is tile than shingles?

Tile is significantly heavier than shingles. Asphalt shingles weigh 200-350 lbs per square, while concrete tile weighs 900-1,100 lbs and clay tile weighs 800-1,000 lbs per square. Most Arizona homes built since the 1980s are framed to support tile weight, but older homes may need structural upgrades.

Can I mix concrete and clay tile on the same roof?

While technically possible, mixing concrete and clay tile on the same roof is not recommended. The materials expand and contract at different rates in Arizona's extreme temperature swings, and they weather differently over time. Choose one material for your entire roof for the best performance and appearance.

Which tile type handles monsoon storms better?

Both concrete and clay tiles perform well in monsoon storms due to their weight and interlocking design. Concrete tile is slightly more impact-resistant (better for hail), while clay tile has a slight edge in water-shedding due to its non-porous surface. Both are Class A fire-rated. The underlayment beneath is your primary waterproofing layer regardless of tile type.
