How Much Does It Cost To Tear Off And Replace A Roof?

Kenneth Wilson

Have you been dealing with a damaged or leaking roof? Or is the roof nearing the end of its expected lifespan? In that case, it’s probably time to consider a roof replacement. Homeowners are looking at spending $18,000 to $28,500 to tear off and replace their roofing. This ballpark estimate covers a 3-bedroom home with two bathrooms, architectural asphalt shingles, and just a bit of roof complexity. Depending on your current roof, the total size, and pitch, it can increase or decrease accordingly.

Before you consult local contractors to get different quotes, let’s discuss everything you need to know to calculate the average cost of roofing replacements.

Costs Factors in Tearing Off and Replacing a Roof

Naturally, your roof replacement costs will depend on different factors. On the low end, you may spend $18,000 with the thriftiest materials. Prices may increase up to $28,500 (or more) for extensive roofs with massive square footage and high-end materials. (Related: Roof Replacement Cost & Consumer Guide)

Most quotes include:

  • The removal of two old shingles layer
  • Professional installation
  • Permit fees (if applicable)
  • Disposal fees
  • Workmanship warranty

Important note: In getting a quote from a local roofing company, ensure that it includes new underlayment installation and chimney refinishing. Ideally, the quote must also cover an ice-and-water shield for your roof.

Size of the Roof

Your roof size is a crucial factor in calculating your roof replacement costs, as it determines the amount of material you need. For your reference, the roof size is commonly measured using “roofing square, " equivalent to 100 square feet.

Roof Slope

The slope of your roof will also determine the total costs of the roof replacement project. If you have a sloped roof, the labor costs may be higher than what you'd typically pay for a flatter roof– as the labor is more intensive. A roof with a slope also requires installing an underlayment system.

Roofs that are genuinely sloped may be an expensive undertaking, considering the scope of the project and the intensive labor needed.

Roofing Material

Another crucial factor to take into consideration is your chosen roofing material. Most commonly, asphalt shingles prove to be a crowd-favorite choice as it is cheaper than both metal and slate materials. (Related: 6 Types of Roofing Materials: Pros, Cons, and Price Comparisons)

But, metal and slate roofs are highly durable, so you may want to consider investing. Not to mention, they are sustainable and eco-friendly picks.

  • Asphalt Shingle Roof – Shingle roofs account for 80% of roofs in North American homes. It is a cost-effective roof replacement material to consider, with different shingles to choose from (asphalt and wood). Replacing a 2,000 square foot roof (the average home size in the country) will cost you $8,000 with strip shingles. A more extensive home of 3,000 square feet costs $18,000.
  • Metal Roofing – Replacing a 2,000 square foot roof with metal costs anywhere between $16,500 and $25,500. A 3,000 square foot roof ranges from $24,000 to $37,500. Prices will depend on the metal quality, with an average life span of 30 to 50 years. You'll find the high upfront costs to be more expensive than other options, but it's all worth it. Metal roofs are highly durable, with little maintenance required. Additionally, heat-reflective coatings can also enable metal roofs to reduce your energy bills by at least 40%.
  • Slate Roof – A slate tile roof replacement of a 2,000 square foot roof runs for $19,000 to $37,000. A more extensive roof (3,000 square feet) may cost you around $30,000 to $60,000. Thanks to slate's durability and sustainability, it's the most expensive choice on this list. The material is also known for its longevity, lasting up to 75 to 150 years. Regardless of these high upfront costs, it's an excellent option for homeowners looking into a new construction roof.

Should You Move Ahead with Roof Replacement?

Suppose your roof has seen better days and is currently severely damaged. In that case, a roof replacement project is crucial to ensure the safety of all occupants in your home. Though it can be a costly project depending on your preferred materials, safety must always be a priority!

Here are some tell-tale signs of a roof replacement (instead of a simple repair):

  • Cracked shingles
  • Sagging
  • Missing granules (bald spots)
  • Leaks or openings in the attic
  • Poor energy efficiency
  • Poor workmanship

In getting quotes from local roofing companies, opt to get at least three or four options. This will allow you to compare the best price for your budget and ultimately make the best decision for your situation.

Take the time to research your contractor options and your roofing material to ensure you'll get the most out of your new roof for a long time. Always keep in mind that it is a hefty investment. As such, your roof replacement project must be taken into careful consideration every step of the way!
