Detailed Breakdown:
What Makes Slate So Special?
Slate roofs have a reputation for lasting a century or more—some even stretch up to 150 years. Slate is a natural stone, which means it’s resistant to fire, heavy winds, and even hail. However, because it’s brittle, it can crack or become displaced over time. Repairs are inevitable if you want to maintain the durability and classic look.
When Do You Need Slate Roof Repairs?
The first step is to identify when your slate roof needs attention. Here are some common warning signs:
- Missing Slates: If you notice a gap, it’s time to call a professional. A missing slate is a weak spot waiting for water to sneak in.
- Cracked Slates: Visible cracks mean the slate can no longer serve its waterproof function. Even a hairline crack can lead to leaks.
- Flashing Issues: The flashing (the metal that seals roof joints) can rust or fail, leading to leaks. This needs repair just as urgently as a broken slate.
- Leaks and Water Damage: Water spots on the ceiling? You likely have a slate issue. Don’t wait—moisture can cause rot and damage the structural integrity of your home.
Steps to Repair Slate Roof
- Inspection: A professional roofer will inspect the entire roof to assess damage, checking for cracked or missing slates and testing the stability of existing ones.
- Slate Replacement: Broken or cracked slates are replaced with new or reclaimed slate, which is carefully matched to the original in size, thickness, and color. This maintains the visual integrity of the roof.
- Resealing Joints: Joints where slates overlap are sealed to ensure waterproofing. Special attention is paid to areas like valleys, ridges, and chimneys where flashing might have deteriorated.
- Fixing Flashing: If the flashing is damaged or rusted, it’s replaced with durable materials like copper or stainless steel, which can last for decades.
- Final Inspection: Once repairs are complete, the roofer will conduct a thorough inspection to ensure the roof is watertight and structurally sound.
DIY Slate Roof Repair: Is It Worth It?
You might be tempted to try a DIY fix to save some cash, but slate roof repair is a job for the pros. Here’s why:
- Dangerous Heights: Working on roofs is risky, especially if you don’t have experience or proper safety equipment.
- Fragile Slates: Walking on slate can cause even more damage. One wrong step could crack surrounding slates and worsen the problem.
- Skill Required: Matching slates and installing them properly takes expertise. A botched job can lead to further leaks and more expensive repairs.
In short, save yourself the trouble and hire a certified roofer with experience in slate roofing.
How Much Does Slate Roof Repair Cost?

- Minor repairs (like replacing a few slates) can range between $500 and $1,200.

Keep in mind that investing in quality repairs will save you money in the long run, as it prevents more costly structural damage.
