Renovating your roof isn’t a job to be taken lightly. Roof repair can cost anywhere from $4,000 to $200,000 depending on the roof’s slope and surface area and the materials used. Calling on the services of an expert is a must to assess the overall condition of your home.
Factors that can increase costs
The inspection
Hands down, an inspection is critical when you’re renovating your roof. If there are issues to address, it is essential to take them into account and correct them before installing your new roof, otherwise more serious and costly problems could occur.
The type of work
It’s important to understand your needs, i.e. whether you need to build a new roof, perform simple renovations or more complex repairs. The price range can vary depending on the nature of the work required.
The materials
The choice of materials for your roof will influence the cost of your roof. However, you must decide based on what you are looking for in terms of durability, look and price.
The surface area
The surface area that needs to be renovated is, without a doubt, one of the biggest factors that will increase the price of your roof. The larger the surface area, the higher the price, so you must choose your materials based on price and surface area.
Which materials to use?
A variety of materials are available to suit all budgets and tastes!
Asphalt shingles
Without a doubt, asphalt shingle roofs are the least expensive option on the market, but they must be replaced more often than other roofing options.
Asphalt and gravel
Asphalt and gravel roofs are laid in layers that work in concert. They are inexpensive and easy to maintain.
Elastomeric or modified bitumen membrane
Elastomeric or modified bitumen membrane roofs are mainly used on flat roofs. They are long-lasting and only require one annual inspection.
TPO or EPDM
TPO or EPDM roofs are more environmentally responsible and are more expensive.
Green roofing
Highly coveted in recent years, green roofs are also eco-responsible but require much more extensive maintenance.
Metal
Metal roofs have a much longer than average lifespan. Given their durability, they are more economical in the long run.
Slate
Slate roofs are also available. This type of roof will not only add a very elegant touch to your home and be very strong, but it is also very expensive.
A flat or sloped roof?
Sloped roofs are known to be easier to maintain and are very popular for residential homes. Sloped roofs give homes a more elegant and classic look, ease snow off the roof and improve water drainage.
Flat roofs are more modern and are more and more in demand as they optimize space. Their main advantage is that, because they require less material, they are often cheaper and easier to access for maintenance.
Here’s a table of roof types with their average price and lifespan:
| Type of roof | Average price/ft² | Lifespan |
| Asphalt shingles | $3.15 to $9/ft² | 15 to 25 years* |
| Metal (aluminum, steel, copper) | $8 to $30/ft² | 50 to 100 years |
| TPO/EPDM | $7.50 to $9.50/ ft² | 25 to 35 years |
| Asphalt and gravel | $8/ft² | 15 to 30 years |
| Elastomeric | $10/ft² | 20 to 35 years |
| Slate | $23 to $40/ft² | 75 to 150 years |
| Green roof | $18 to $40/ft² | to 50 years |
*Given the ever-increasing quality of the materials, the durability of asphalt shingles has tended to improve over time. The latest asphalt shingles now have a lifespan of more than 50 years.
In conclusion, if you are thinking of building, renovating or replacing your roof, you must identify your needs and respect your budget. It’s important to take your time and consider the options available as well. Making the right choice can be more complicated than you think!
