How Much Does A Roof Replacement Cost?

Managing your budget is an important aspect of any home renovation. When it comes to roofing, there are many things to consider and estimators can provide a detailed quotation for what your roof will cost. This will be very useful to you;  however, it is important that you understand what you’re paying for. If your goal is solely to keep your roof replacement costs low, you may not be paying for the quality that you want. Here are a few components of roof replacement costs that homeowners should keep in mind.


The decision of what material to use on your roof has a significant impact on the total cost of the project. Typically, there are four types of roofing materials to consider:

  • Asphalt Shingles: this is the most common type of roofing material. These shingles will last about 20 years depending on the type you choose (architectural or 3-tab). It is the most cost effective type of material which is why it the popular choice for most homes.
  • Wooden Shingles and Shakes: These shingles cost more than asphalt shingles. Their lifespan is anywhere from 15-30 years, require more maintenance than other roofing options, and are highly-energy efficient.
  • Metal: This type of roof is gaining popularity. However, metal roofs cost more than asphalt or wooden shingles. This is because they outperform other roofing materials in energy efficiency, longevity, durability, maintenance costs, and more.
  • Slate: This is the most luxurious of roofing materials. It can last up to 150 years and provides the best durability against the elements, however it is a heavy substance/ This can become a challenge because it requires more material on the deck for support which drives up the overall cost of the system. In addition to this, slate itself is a very expensive material.

Pitch and Slope of the Roof

Any complexity in the staging, safety, and general labour is going to drive up your roof replacement cost. If people cannot walk on your roof because of a steep slope, expect a higher price.

Roof Removal

Roof tear-off is usually factored into expected roof replacement costs. Don’t forget to think about the cost of disposing of materials though. Metal and wood roofing systems are easier to recycle than asphalt and are therefore cheaper to dispose of. Also factor in total weight as this is significant to the total cost.

Components Beyond the Shingle

A roof is made out of an entire system of materials, not just shingles. When working with a contractor, pay attention to the type of underlayment, decking materials, insulation, and ventilation materials and systems chosen. If the costs seem too high, discuss your options with your contractor.

Warranty Coverage

The two types of roofing warranties—manufacturer and contractor— can be confusing for homeowners. Here’s what you need to know:

Manufacturer warranties protect the roofing materials and require strict adherence to manufacturer guidelines and procedures during installation. Your roofing contractor should always be a Preferred and/or Authorized Contractor of whichever manufacturer’s products they install. This will ensure the manufacturer cannot deny a claim due to improper installation of the products.

Contractors warranties cover workmanship. The industry standard is 10 years. Make sure your roofing contractor has been in business for this length of time (at least).  Their past is a good reference for their future success and if your warranty will still be in tact should the need arise.
