Common Problems With Clay Tile Roofs
Let’s now explore the most common problems homeowners might face with clay tile roofs.
1. Cracked or Broken Tiles
Why It Happens:
- Clay tiles are hard but can break if something heavy falls on them.
- Walking on the roof can also crack the tiles.
- Sudden changes in temperature (like very hot days followed by cold nights) can cause tiles to crack over time.
Why It’s a Problem:
- Cracks can let water in, which may lead to leaks inside your home.
- Broken tiles affect the look and strength of the roof.
How to Fix It:
- Replace the broken tile with a new one.
- Try not to walk on the roof. If you must, step carefully on the lower part of the tile, not the middle.
2. Water Leaks
Why It Happens:
- Broken or shifted tiles can leave gaps for water to get through.
- The layer under the tiles (called underlayment) may wear out over time.
- Poor installation can also cause leaks.
Why It’s a Problem:
- Water leaks can damage your ceiling, walls, and insulation.
- It can also lead to mold, which is harmful to your health.
How to Fix It:
- Replace damaged tiles and repair the underlayment.
- Always use a skilled roofing contractor to check and repair leaks.
3. Mold and Mildew
Why It Happens:
- Water that stays on the roof for too long creates a perfect place for mold to grow.
- Poor drainage or blocked gutters can make this worse.
Why It’s a Problem:
- Mold and mildew can spread and damage your roof.
- It can also affect air quality inside your home.
How to Fix It:
- Clean your roof regularly using safe roof cleaners.
- Make sure gutters and drains are clear and working well.
4. Loose or Slipping Tiles
Why It Happens:
- Wind and heavy rain can shift tiles from their position.
- Aging roof materials may no longer hold the tiles in place.
- Poor installation can also be a reason.
Why It’s a Problem:
- Loose tiles can fall off and cause injury or property damage.
- They also make your roof look uneven and messy.
How to Fix It:
- Call a roofing professional to put the tiles back in place.
- Make sure they are secured with strong fasteners or clips.
5. Underlayment Deterioration
Why It Happens:
- The underlayment is the waterproof layer under the tiles.
- It can wear out after 15–25 years, especially if exposed to moisture or sun.
Why It’s a Problem:
- If the underlayment fails, water can easily seep into your home.
- Even if the tiles look fine, your roof may still leak.
How to Fix It:
- Replace the underlayment when needed.
- This is usually done by removing and reinstalling the tiles.
6. Algae or Moss Growth
Why It Happens:
- Clay tiles can collect dirt and moisture.
- This creates a perfect environment for moss or algae to grow.
Why It’s a Problem:
- Moss and algae can make the roof slippery and unsafe to walk on.
- They can also trap moisture, which may weaken the tiles.
How to Fix It:
- Use a soft wash or eco-friendly cleaner to remove growth.
- Trim nearby trees to let sunlight reach the roof.
7. Improper Installation
Why It Happens:
- Not all roofers have experience with clay tiles.
- Cutting corners during installation can lead to many future problems.
Why It’s a Problem:
- Poorly installed tiles can slip, break, or leak.
- The roof may not last as long as it should.
How to Fix It:
- Always hire roofing contractors with experience in clay tile roofing.
- Ask for references and look at past work before hiring.
8. High Repair Costs
Why It Happens:
- Clay tiles themselves are not very expensive, but the repair work can be.
- It often requires special tools and skilled labor.
Why It’s a Problem:
- Homeowners may delay fixing issues because of the cost.
- Delaying repairs can make problems worse over time.
How to Fix It:
- Do regular maintenance to avoid costly repairs.
- Fix small issues quickly before they grow.
9. Difficulty Matching Tiles
Why It Happens:
- Over time, your original clay tiles may no longer be available.
- New tiles may look different in color or shape.
Why It’s a Problem:
- It can make your roof look patchy or mismatched.
- It may also affect the resale value of your home.
How to Fix It:
- Keep extra tiles from your original installation if possible.
- Work with a roofer who can help you find the best match.
10. Heavy Weight
Why It Happens:
- Clay tiles are heavier than asphalt shingles or metal roofing.
Why It’s a Problem:
- Not all homes are built to hold the extra weight.
- The structure may weaken or sag over time.
How to Fix It:
- Have a structural engineer check if your home can support clay tiles.
- If needed, reinforce your roof structure before installation.
How to Prevent Problems With Clay Tile Roofs
Now that we know the common problems, let’s talk about how to prevent them:
1. Regular Inspections
Have your roof checked at least once a year or after a big storm.
2. Clean Gutters and Downspouts
Keep water flowing away from your roof to avoid moisture buildup.
3. Trim Trees Near Your Roof
This reduces shade and helps prevent moss and algae growth.
4. Don’t Walk on the Roof
If you need to go up, hire a professional who knows how to move safely on tile roofs.
5. Fix Small Issues Quickly
Don’t wait for big problems. Fix cracks, leaks, or loose tiles as soon as you notice them.
