Slate Roof Durability
Slate roofing is one of the most durable roofing materials on the market and has been used in roofing applications for centuries. It continues to be a popular choice due to its aesthetically-pleasing appearance and superior durability.
Slate is a quarried rock material that is shaped into roofing tiles by hand or machine and then graded for quality according to ASTM standards.
|Grade||Expected Lifespan / Durability|
|S2||40 - 75 years|
|S3||20 - 40 years|
Despite the fact that slate roofing is one of the most weather-resistant and durable roofing materials out there, you’ll most likely need some roof repairs at one point or another.
Slate roofs are very repairable, but the key is to hire a roofing contractor with experience in installing and repairing slate roofing. This will help to ensure the repair lasts.
Cost of Slate Roof Repair
The cost of repairing slate roofing depends upon several factors, like:
- Where you live
- Type of roof damage
- Extent of the damage
- Complexity and steepness (pitch) of the roof
- Type of slate used
A very minor slate roof repair can cost a minimum of $200, including swapping out a tile or repairing a small section of flashing.
More complex roof repairs can easily cost several hundred to thousands of dollars due to the relatively high cost of slate roofing material and the level of expertise required to get the job done correctly.

Slate Roof Maintenance Tips
One of the greatest benefits slate roofing offers is the minimal amount of maintenance required to keep the roof in tip-top shape. You should clean the gutters at least once per year and have a slate roofing contractor do a thorough inspection of the roof every five to seven years.
Fallen tree limbs and large hail can damage slate tiles, so be especially wary of roof damage following a major wind or hail storm.
Lastly, wear soft-soled shoes when walking on a slate roof because it is possible to crack the tiles while walking on them with hard shoes.
Slate Roof Repair vs. Roof Replacement
Debating whether to repair slate roof damage or replace the entire roof is a tough decision compared to other types of roofing. Since slate roofing materials are expensive and take a certain level of expertise to repair, a complete roof replacement may be a better choice if the damage to the roof is widespread.
According to the U.S. Department of the Interior’s Technical Preservation Services, it’s generally a more cost-effective option to completely replace a slate roof that has damage on 20% or more of the tiles. Keep in mind this is just a general recommendation, and you should consult with a slate roofing contractor before making a final decision.
