Quick Answer
Okay, so you've found a cracked or broken tile on your roof. This isn't just a cosmetic issue; the tile's primary job is to shed water quickly, protecting the crucial waterproof underlayment beneath. When a tile is damaged, water can penetrate directly to this underlayment. Over time, exposure to moisture and UV rays degrades the underlayment, eventually leading to leaks into your home. The immediate fix is to replace the broken tile, but it's essential to inspect the underlayment underneath for any damage. For a simple replacement of one or two tiles, you can expect a professional to charge roughly $250-$600, depending on the tile type and accessibility.

Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Visually inspect the roof for cracked, broken, or missing tiles from the ground using binoculars.
Step 2
If safe, access the roof to closely examine individual tiles for damage and check for slipped tiles. Use proper safety gear.
Step 3
Carefully lift the overlapping tile and remove the broken pieces to inspect the underlayment beneath for signs of deterioration or water penetration.
Step 4
Check the attic or interior ceilings for water stains or active leaks, tracing them back to their source on the roof if possible.
Step 5
Assess the overall condition of the roof for widespread damage versus localized issues.

When to Call a Professional Roofing
- When multiple tiles are damaged, or the damage covers a large area.
- If you see any signs of leaks inside your home, like ceiling stains.
- When you inspect the underlayment and it appears torn, brittle, or compromised.
- If your roof is steep, on a second story, or you aren't comfortable with heights and safety procedures.
- When dealing with complex or specialty tiles like slate or certain clay profiles that require special tools.
- If you can't find an exact match for your existing tiles.
Prevention Tips
- Conduct regular roof inspections from the ground with binoculars to catch minor issues early.
- Keep trees trimmed well away from the roof to prevent branches from falling on it.
- Avoid walking on tile roofs unless absolutely necessary, and if so, learn the proper technique to walk on the lower overlap of the tiles to prevent breakage.
- Ensure proper original installation with high-quality materials, especially the underlayment.
- Address small repairs promptly to prevent them from escalating into larger, more costly problems.
