Slate Roof Calculator & Estimator
If you are considering a slate roof, our roof slate calculator and estimator can provide ballpark pricing for both natural slate and the numerous faux slate alternatives on the market. Slate roofs are expensive, probably the most expensive material on the market, averaging $4.5 per square foot for the tiles themselves. The installation costs and roofing removal costs are also some of the priciest in the business.
Slate Tile Costs
The average slate tile runs $4 to $5 per square foot. Like all roof tile materials, slate tiles come in a variety of sizes, thicknesses and ratings that affect the cost per square. (Most roofing projects are bid out by the square or 100 square feet, but it's easier for most homeonwers to break it down by the square foot).
Tear Off Or Removal Costs
Removing worn, cracked or simply old slate tiles (or whatever existing material is currently on your roof) is a labor intensive and important part of the project. The roofers bring out a dumpster to dispose of the old tiles, erect scaffolding for safety and easier access to the roof. They take off all the material until they get to the wood boards and then lay down a waterproof underlayment, drip edges and all necessary ridge lines. More on roofing removal prices.
Slate Installation Cost
Installation costs for slate roofs is a the very top of the roofing installation price range - $5 to $12 per square foot. There are a number of reasons for this; the most important of which is that roofing with slate tiles is tricky and takes skill. There aren't as many companies that specialize in slate roofing so the contractors can charge more (not necessarily fair, but that's life I suppose). Where you pay on this range of pricing depends on alot of factors, including the slope on the roof, the type of roof, the number of hips and ridges, how many obstacles have to be roofed around, the time of the year, size of the project, etc.
