5 Reasons To Avoid Clay Roofing in Missouri By Thomas McCormack, Owner of M5 Contracting – Holts Summit, MO When I first got into the roofing business here in Holts Summit, I was drawn to all the different types of roofing materials out there — asphalt shingles, metal panels, wood shakes, and yes, clay tiles. Clay roofing has this timeless charm to it. There’s no denying it looks beautiful, especially on Spanish-style or Mediterranean-inspired homes. Over the years, I’ve had the chance to repair, inspect, and even install a few clay roofs in Missouri. But if I’m being totally honest — and I always aim to be — I generally recommend my customers steer clear of clay tile roofing here in Missouri . Why? Because our climate and conditions just don’t play well with this material. Sure, it looks great on a postcard from California or Arizona, but Missouri’s unpredictable weather, heavy storms, and seasonal shifts can turn a clay roof into a real headache. In this blog, I’ll walk you through the five biggest reasons you should avoid clay roofing in Missouri , based on what I’ve seen firsthand over the years. Whether you’re building new, thinking about a roof replacement, or just curious about your options, I hope this helps you make the best choice for your home. 1. Clay Tiles Crack Under Missouri’s Freeze-Thaw Cycles Missouri weather is wild — and I’m not just talking about tornadoes. One of the biggest problems we face here is something called the freeze-thaw cycle . We might have a mild 60-degree day in February followed by a hard freeze that same night. This constant up-and-down in temperature wreaks havoc on roofing materials that absorb moisture — like clay. Clay tiles are porous, meaning they soak up water. When that water freezes, it expands, and over time, that expansion causes the tiles to crack, chip, or even break apart completely. It doesn’t take a major winter storm to do this — just repeated cycles of freezing and thawing can slowly destroy a clay roof tile by tile. This is one of the most common issues we see when inspecting older clay roofs. By the time a homeowner spots the damage from the ground, there could already be dozens of cracked or compromised tiles up top. Bottom line: Clay tiles just aren’t built for climates with harsh freeze-thaw cycles like we have here in Missouri. 2. Clay Roofs Are Extremely Fragile and Easy to Damage One of the biggest misconceptions about clay tiles is that they’re super durable. In truth, they’re durable when it comes to things like rot and pests — but they’re very brittle when it comes to physical pressure or impact. Just walking on a clay tile roof the wrong way can cause breakage. That makes basic maintenance, chimney inspections, or even cleaning out your gutters a risky job. A misplaced step can lead to several broken tiles — and suddenly a simple task turns into a repair job. Now factor in Missouri’s severe weather. Our state sees its fair share of: Wind-blown debris Falling tree branches Hailstorms Ice dams Each of these can spell trouble for a clay roof. Even a medium-sized hailstone can crack a tile. And when a few tiles break, it creates vulnerabilities that can lead to leaks, underlayment damage, and mold growth in your attic. Bottom line: Clay roofs may look tough, but they’re incredibly fragile — and Missouri’s stormy conditions don’t do them any favors. 3. They’re Incredibly Heavy and Require Special Structural Support Another downside that often surprises homeowners is just how heavy clay tile roofing is. To give you some perspective: Asphalt shingles weigh around 2–3 pounds per square foot. Clay tiles can weigh up to 12 pounds per square foot — or more, depending on the type. That kind of weight isn’t something you can just slap on any old roof. Your home needs to be specifically engineered to handle it, which often involves reinforcing the roof deck, trusses, and other structural components. If your current home wasn’t designed for a clay roof, installing one means a major upfront cost just to upgrade your framing. In my experience, very few homes in mid-Missouri are built with clay roofing in mind. Trying to retrofit one onto an existing structure is almost always more trouble (and money) than it’s worth. Bottom line: Clay roofing is heavy, and most Missouri homes aren’t structurally prepared for the extra weight. 4. Repairs Are Expensive and Complicated Let’s say you go ahead and install a clay roof anyway. What happens when it eventually needs repairs? The truth is, clay tile roofing is expensive and tricky to repair — especially here in Missouri, where the materials and experienced labor can be hard to come by. If a tile breaks, it’s not always easy to find a perfect color or shape match. This can leave your roof looking patchy or mismatched over time. And remember, you can’t just nail a replacement tile in place like you can with asphalt shingles. Clay roofing requires precision, careful handling, and specific techniques to ensure the tile sits properly without cracking. Improper repairs can cause water pooling, tile shifting, or more breakage down the line. We’ve been called in to fix DIY clay roof repairs gone wrong more times than I can count. It’s usually not the homeowner’s fault — it’s just that clay roofs require specialized knowledge and tools that most people (and even many general contractors) don’t have. Bottom line: Repairing a clay roof in Missouri is expensive, time-consuming, and often frustrating. 5. Poor Fit for Missouri’s Climate and Roofing Needs This one’s the kicker. Even if you had the money, the structural support, and access to expert repair crews… clay roofing still isn’t a great fit for our local climate. Missouri throws everything at your roof: Ice and snow in the winter Intense heat and UV in the summer Wind, hail, and flying debris in spring and fall High humidity and mold growth risk Sudden temperature swings year-round Clay tile roofs are best suited to dry, mild, consistent climates like parts of California, Arizona, and the Mediterranean — not a place where you can get all four seasons in one week. Over time, the tiles degrade faster, repairs pile up, and the maintenance costs start to outweigh the benefits. In addition, clay roofs don’t offer the same flexibility as more modern roofing systems when it comes to energy efficiency, venting options, or storm-resistant designs. Bottom line: Missouri homeowners deserve roofing systems that are built for Missouri weather — and clay just isn’t one of them. Final Thoughts from Thomas If you’ve got your heart set on a certain look, I get it. Clay roofs are gorgeous — no argument there. But from a contractor’s perspective, and as someone who wants the best for my neighbors here in Holts Summit and across Missouri, I wouldn’t recommend clay roofing for your home. There are plenty of other options that offer beauty, durability, and better performance in our climate: Architectural shingles that mimic clay’s texture Metal roofing with baked-on finishes that last decades Synthetic slate or composite tiles designed to look like clay but perform like asphalt or metal At M5 Contracting, we specialize in helping Missouri homeowners find the right roofing system for their needs — not just what looks good in a brochure.
