# Replacing Your Roof? Here’s How to Tell How Much it Will Cost

“How much is it gonna cost?” is the question you always have to ask when contemplating a new roof. There are many roofing materials out there to choose from and they come in a wide range of prices. The material alone isn’t the only factor that can determine price. So if you’re contemplating a new roof, here’s how to tell how much it’s going to cost you.

**Cost per square**

The basic unit of measurement that roofers use in calculating cost of materials is a square—not a square foot. A square is a ten foot by ten foot section, or one hundred square feet. Simply put, the more squares needed to cover your roof, the more it will cost. If you know the cost per square of the materials you’re considering and you get an estimate of how many squares your roof is from your roofer, you have an idea of what the cost is going to be for the shingles. Standard asphalt shingles might cost as little as $75 per square while slate tiles can set you back up to $2,000 per square.

**Lifespan and cost per year**

Of course the cost per square alone is not a good enough unit of measurement because an asphalt shingle roof might need to be replaced every 15-20 years or so while a metal roof can last decades and a slate roof might last 150 years or more. You can calculate cost per year by dividing the cost per square by the expected lifespan of the room. This will tell you the cost per square per year.

Ultimately, the best course of action is to speak with a Spokane roofing company to get a free estimate.
