4 Signs That Indicate Repairs Are Needed

Slate roofs are incredibly strong, but they’re not indestructible. Over time, a slate roof may require servicing due to weather exposure, aging, or accidental damage. Here are some common signs to look for that may indicate slate roof repairs are necessary:

1) Cracked or Broken Slates

If you notice that some of the slates on your roof are cracked or broken, it’s essential to have them repaired. Cracked slates can cause water to leak into your home, leading to expensive water damage repairs.

2) Missing Tiles

If you spot missing slate roof tiles on your roof, it’s crucial to replace them as soon as possible. Missing slates can also cause water to leak into your home and make the interior prone to issues caused by the elements.

3) Leaks

Have you noticed water stains or moisture in your home? If so, it’s essential to have your roof inspected for leaks. Leaks can be caused by cracked or missing slate tiles, or they may be a sign of a more significant issue with your roof.

4) Damaged Flashing

Flashing is the material that seals the joints and edges of your roof. If you see that your flashing is broken or missing, it’s essential to have it repaired or replaced to prevent water damage and other problems.

Slate Roofing Repair or Replacement: Factors to Consider

When deciding between slate roof repair or replacement, there are several factors to consider. Below are a few things to keep in mind:

The Age of the Roof

If your slate roof is nearing the end of its lifespan, it may be more cost-effective to get a new roof rather than continue making repairs. Slate roofs can usually last 100 years. But if it’s significantly over that timeframe, consider new slate roof installation.

The Extent of the Damage

If your slate roof has extensive damage, such as multiple broken or missing slates, it’s probably better to replace the entire roof rather than make repairs. Since you know that slate roofing materials last a long time, the investment in a new roof will be well worth it.

Structural Issues

If your slate roof has structural issues, such as sagging or bowing, replacement is the better option. But of course, once a professional roofing contractor inspects everything, they can provide more insight into whether you need slate roof repair or replacement.


Your budget will also play a role in deciding between replacing or fixing your roof. Repairing a slate roof is often more affordable in the short-term, but replacing the roof may be more practical in the long run.

The Contractor

It’s essential to find a qualified contractor who has experience working with slate roofs. A professional roofing company can help you make an informed decision about whether to repair or replace your slate roof. No matter which option you choose, they should be able to do the job effectively.

The Cost of Slate Roof Repair vs. Replacement

The price of slate roof repair or replacement depends on several factors, such as the extent of the damage, the size of the roof, and the materials used. You’ll pay roughly $5,000 to fix your slate roof.

On the contrary, complete roof restoration could cost nearly $60, 000. But again, the price is determined by square footage and other details.

The Benefits of Replacing a Slate Roof

While repairing a slate roof is an economical option, there are many benefits to replacing it instead. Here are some of its advantages:

  • Upgraded materials: Replacing a slate roof allows you to upgrade to newer, more durable materials that may be more energy-efficient. Even though your current slates are able to hold up, it doesn’t hurt to get something new and modernize your roof.
  • Enhances the appearance of your home: Replacing a slate roof allows you to enhance the look and curb appeal of your home. If you’ve been wanting to do renovations on your house, your roof is a good place to start. Not only will it look better, but it’ll be in greater condition to withstand the elements.
  • Prevents future repairs: Let’s be honest, no one likes dealing with repairs, but roofs require regular maintenance. Thankfully, replacing a slate roof can prevent the need for frequent repairs in the future.
  • While you may have to get work done at some point, your roof probably won’t require any attention for quite some time after getting a replacement.
  • Increases the value of your home: Replacing a slate roof can increase the value of your home and provide a better return on investment. A durable roof is an attractive feature for potential buyers.
