Most homeowners only think about their roof when it is in dire need of repairs. The small leaks are easily ignored and regular roof inspection is not something most homeowners think about. What most people fail to understand is that by properly maintaining the roof and replacing it at the end of its lifespan, you ensure it does its job of protecting everything that lies below it. Replacing the roof also increases the value of a property. Home buyers are more attracted to buildings with a well maintained or new roof.

This guide will take a look at the available repair options and how much you can expect to pay. For a more accurate estimate, you can contact D’Angelo & Sons Roofing; one of the leading roofing companies in Canada.


You will be spoilt for choice when searching for roofing materials to use on your house. The material you select will affect the cost of roofing and lifespan. The three main factors that influence the material you choose are:

  • Your budget
  • Longevity
  • Style 

The saying, ‘you get what you pay for’, holds true when it comes to roofing. The more you spend upfront the longer the roof will last. Your budget and the duration you want to stay in the house will sway you towards favoring longevity or budget. If you have a specific look in mind, your choice will be swayed towards style. The final decision rests with you. Here are the main roofing materials you will find on the market.



These are some of the most affordable roofing materials on the market hence the reason they are so popular among homeowners. The cost of installing asphalt roofs vary depending on the size of your roof and the type of asphalt you are using. The cost lies between $2,000 and $11,000. In Canada, the average installation cost is $4,750.

The lifespan of asphalt shingles is between 15 and 30 years. Several factors affect the mileage such as the weather (warmer climates cause asphalt roofs to wear faster) and the presence of pests. The main advantage of an asphalt roof is the low shingle price. Asphalt shingles are also very versatile in appearance and can be made to mimic just any material from wood to slate and so on. The customization options are virtually unlimited.

On the flipside, asphalt shingles are not the most durable roofing options. They are prone to aesthetic damages such as cracks, color loss and falling off. This causes the cost of repairs to be a bit high. These materials are also not environmentally friendly since the material is petroleum based and requires a lot of energy during manufacturing. They are hard to recycle and often end up in landfills where they produce methane gas as they decompose.

Other than that, the pros outweigh the cons. There is a huge variety of asphalt shingles to pick from with organic and fiberglass shingles being the most popular. What is more, is that you will find just any style you need.



These are more expensive than asphalt roofs. You will spend between $2,048 and $25,704. The average cost of installing metal roofs in Canada is $10,365. On the bright side, metal roofs last 4 times longer than asphalt shingles. You may never need to replace them again.  

The advantages of using metal roofs include:

  • Energy efficiency: They manage the elements better and will save up to 40% in energy bills. They are also greener than asphalt which means you may be eligible for tax credits.
  • Low maintenance: They can withstand almost anything that is thrown at them.
  • Long lasting: They last up to 60 years.
  • Insurance saving: They can save you 30% on your insurance because they are more durable.
  • Easy installation: They can also be installed on existing asphalt roofs.
  • Lighter: They're almost half the weight of asphalt. This means less stress on the trusses or rafters.
  • Resale value: Potential buyers are willing to pay premium prices on homes that have metal roofs.


  • Expensive: The upfront cost is high but they will save you more money thanks to their long lifespan.
  • They don’t offer noise insulation.
  • Difficulty expanding and contracting. The right fastener will be required.
  • Difficult to match if a section needs to be replaced.
  • Hard to break through during emergencies

There are several types of metal roofs to choose from. The most popular ones are aluminum, tin, copper, stainless steel and zinc. There are many styles to pick from to achieve the look you desire



Even after factoring in the cost of roofing materials, you will also need to consider other additional costs. These additional costs include the following:

  • Cost of removing the old roof

It is possible to install new asphalt shingles on an existing deck. However, if the deck is in a bad condition or you already have two or more layers already installed, you will have to remove the current roofing. Metal roofs also require that you remove the current roof before installing the new one. The cost of removing the old roof is between $550 and $1,500 for ranch-style homes. The cost varies depending on difficulty, location and size of the roof. 

  • Rafters or trusses

If the trusses or rafters are damaged or they can’t support the weight of the new roof, you will have to install new ones. The cost of reinforcing or installing new rafters or trusses is between $1,000 and $13,000.

  • Algae and fungus

If you live in an area that gets lots of rainfall or high humidity, you have to think about buying algae resistant shingles. This will bring the cost of roofing up by 10% to 15%.

  • Pitch

When it comes to roofing, safety is a top priority. A steep pitch means your roof will be riskier to work on. Roofers have to take precaution and this may push the cost of installation up. Steep pitches also require underlayment in order to get the Class A fire rating.

  • Weight

Although thicker shingles withstand the elements better, they cost more to install. Added weight means more trusses or rafters support. This will cause the costs to go up.

Always discuss your roofing needs with a roofer well in advance. The roofer will help you know what to expect before, during and after the project.
