How to Calculate Roofing Costs?

There are many things which must be taken into consideration when estimating roofing costs. Although the roofing material determines a huge chunk of the budget, there are other things to consider such as:

  • Number of stories
  • Number of chimneys
  • Geographic location
  • Complexity of the roof
  • Permits and taxes
  • Roofing company

Please Note: Online calculators do not consider the following:

  • Taxes required to remove and install new roofing
  • Systems on the roof which need replacement
  • Damaged roofing/structure which need replacement
  • Geographic location and the effect on price
  • Roofing material quality from several brands

Depending on the type of roof, there are various options available in the market. There are two types of roof, pitched and flat. A pitched roof is an angled roof, while a flat roof is flat and costs less than pitched ones. Flat roofs installation is less expensive, but they will require more maintenance and could end up costing more in the long run because of their drainage issues.

Factors that Affect Metal Roofing Prices

There are a few factors which will dictate the cost of your new metal roof and they are the following:

  • Substrate metal
  • Panel design
  • Finish (Coatings)
  • Underlayment
  • Roof design and location
  • Labour cost
  • Stripping and disposal


Aluminum and galvanized steel are commonly used for residential roofing because they give the best value for money. There are also other exotic materials such as stainless steel, copper, and zinc but they are not popular because they are costly. Generally, the price of materials used for roofing is highly dependent on the supply and demand of raw materials, as well as the processing cost.

Panel design

There are two major design choices which dictate price, and they are interlocking panels and overlapping panels. Interlocking panels cost more because they have more structural detail, undergo an immense forming process, and take up more space. They also tend to have better quality because they are interlocked on four sides which contributes to the cost.


Another important factor that dictates the lifespan of roofing is finish, otherwise known as coating. The most economical form of coating is the polyester based paint. It is cheap because it has a limited lifespan. PVDF or Polyvinylidene Flouride, on the other hand, is widely regarded as the gold standard in the industry because of its durability, chalk and fade resistance, and adhesion.


Often unnoticed, the underlayment of the metal roof is a vital second line of defense against the harsh elements. If the roof is new build, it will require what is called ice and water shield which costs five times as much as the breathable synthetic membrane which is most often used for re-roofing over asphalt.

Roof Design and Location

Roofing contractors classify roofs as “easy” or “difficult” depending on physical location and structure. Is special equipment needed for installation? Is it walkable? Are there other elements which will prolong the installation time? For instance, Toronto requires installers to purchase special parking permits and this contributes to the cost.

Labour cost

Most providers hire subcontractors to do the installation job for them. Generally, established contractors command higher prices because they have more liability insurance, WSIB premiums, project managers, as well as training programs. The input of highly-qualified project managers is vital because they give recommendations for proper installation, water management, and insulation.

Stripping and disposal

Aside from the cost of the new metal roof, there is also the cost to strip and dispose of your old roof. Using a lightweight product for re-roofing may eliminate stripping and disposal cost. It is important to check your province’s building code for weight limitations on roofing structure or get advice from an expert.

Metal Roofs Advantages

Metal roofs cost more than other types of roofing materials, such as asphalt because they last four times longer. Although less popular because they cost more, the advantages of using metal roofs far outweigh the disadvantages.

  • Lasts longer. Metal has a lifespan which is four times longer compared to asphalt.
  • Doesn’t require as much maintenance. Metal can withstand the elements and does not peel compared to other materials.
  • Energy efficient. Metal roofs can help you save as much as 40% on your energy bills. Compared to asphalt, metal is made from greener materials which makes it eligible for tax credits.
  • Easy to install. There are cases when metal can be installed over existing asphalt roof so the costs for stripping and disposal are eliminated.
  • Helps you save on insurance. The durability of metal roofs can help you save as much as 30% on insurance.
  • Lightweight. Metal roofs weigh only half as much as asphalt so it will cause less stress on trusses or rafters.
  • Resale value. Because of the long lifespan, energy efficiency, and easy maintenance, potential buyers are more willing to pay a premium for metal roofs.

Additional Roofing Costs

Aside from the current condition of your roof, there are other factors which affect the installation process and the cost of your roofing project.

Removing old roof

If your roof is still in good condition, you will be able to save on stripping and disposal because you can just place new asphalt shingles on top of the old ones. However, if your roof is already in poor condition or you already have two layers of shingles on your roof, the they have to be removed before a new one is installed, and this means additional expenses.

Rafters or trusses

Rafters or trusses gives your roof the support it needs. Adequate support is needed or else your roof can come crashing down. Costs vary widely from $1,000 to $13,000.

Algae and fungus

People who live in places where there is high rainfall or humidity need to consider algae-resistant shingles that resist discolouration and damage, giving your roof a longer lifespan. Algae and fungus-resistant shingles coast as much as 15% more but it is a worthwhile investment.


As with any project, safety is of paramount importance. Homes with an exceptionally steep pitch need more precautions. It is a must to ensure that installers are as secure as possible and this translates to added steps in the project, as well as added costs.


The thicker the shingles, the longer they will last because they can withstand the elements better. However, the added weight means more support needed from your trusses or rafters, which is tantamount to additional costs.

Roof Replacement or Repair?

Should you repair your roof or just replace it? if your roof is relatively new and the repairs required are simple, then by all means opt for a repair. However, if your roof is more than 2 decades old and requires major repairs that will cost you a substantial amount of money, a full replacement may be necessary. Consult a roofing expert for an evaluation so you can decide which course of action to take.

Metal roofs withstand the elements better and last longer. Steel can also be easily matched to the style home’s style by painting. Copper panels is a type of metal roofing that up to $1,500 per square. A cheaper option are steel roof panels that cost from $300 to $800 per square.
