How Much Does Repairing or Installing a Slate Roof Cost?

People have used slate roofs for centuries because they’re durable against weather, fire, and infestations. Homeowners today opt for slate for the very same reasons. Many also like slate roofs because of their classic, elegant aesthetic.

How Much Does Repairing or Installing a Slate Roof Cost?

Before you opt for a slate roof, you should have a good idea of how much the process will cost.

Benefits of Slate Shingles

  • Aesthetics – The natural color and clean, crisp lines of slate shingles make them a great roofing choice for homes of all types, from traditional to modern.
  • Durability – Industry experts say slate roofing can last anywhere from 50 to 100 years. That means if you plan to replace the roof on your forever home, a slate roof could be the last one you’ll ever need. Properly installed, a slate roof will help protect the underlayment and the sheathing on your roof from water, helping reduce the risk of water damage.
  • Fire-Resistance – Slate is fire-resistant. While this won’t protect the wooden elements of your home from burning in a house fire, it does mean that if you live in an area where wildfires are common, your home will not ignite due to an ember landing on the roof.
  • Maintenance – Slate shingles are much easier to maintain than some other roofing types. While maintenance for slate roofs is infrequent, it can be more time-consuming and expensive.

How Much Does Slate Roof Repair Cost?

The demand and pricing for most construction materials have gone up recently. That means repairing a slate roof today is more expensive than it was only 12 months ago. Depending on the material, prices have increased from 10% to 15%.

There are two types of slate roofs: natural and synthetic. While we will discuss the costs associated with natural slate roof repair and replacement, the prices for synthetic slate roofing are around half of the cost of natural slate.

The average cost to repair a slate roof is around $1,806. National averages range from $746 to $2,878. The most important factor when determining how much it will cost to repair a slate roof is the size of the job.

If you only need to replace a single slate shingle, it will only cost around $250. If you need a large section of your slate roof repaired, the cost can reach $5,000. Contractors’ estimates factor in the price of labor, supplies, and any special costs to dispose of your old roofing materials. Contractors will also charge for any permits needed to repair or replace a roof.

How Much Does Slate Roof Installation Cost?

The cost of installing a new slate roof is much higher than simply replacing or repairing a small patch. Roofing jobs are priced by the “square.” A single square of shingles covers 100 square feet of your roof. If you have a roof that is 2,000 square feet (the national average), you will need to purchase 20 squares of slate shingles. On average, slate roofing costs around $15 per square foot, so the shingles alone will cost around $30,000.

The installation of slate shingles is a bit different than traditional shingles. While the process of installing flashing, drip edge, underlayment, and ice guards is the same, slate roofs require copper roofing nails, which are strong enough to go through the slate. With all of the other pricing elements factored in, slate roofs cost between $30,000 and $50,000 to install on average.

Having a slate roof on your home can help protect your property for decades. There is a reason that slate roofs have been a favorite option for homeowners dating back to the 1800s. While they are more expensive to install, their durability, aesthetic, and lack of required maintenance make them a great choice for your property.
