The Average Roof Replacement Cost In Ottawa

Replacing your existing roof or installing a new roof is no easy task and requires knowledgeable experts to provide reliable results. It’s an investment into your home that you don’t want to cheap out on. Nobody wants to find themselves in a position where they have to replace their roof much sooner than if it were done properly the first time around.

Before committing to getting your roof replaced, it’s important to have a professional evaluate the current state of your roof. With a proper assessment, you can decide whether a repair or a replacement is your best choice. Once a decision has been made, make sure to check that the roofers that you’re hiring are insured, experienced, and provide results that past clients are satisfied with.

The most common materials for roofs in the Ottawa are asphalt shingles and metal roofs. Asphalt shingles are a popular choice because they are durable, long-lasting, and are the most affordable option for new roof installations. The cost of an asphalt roof in Ottawa varies between $4,000 – $14,000 – with the average cost being roughly $8,000.

Metal roofs are a considerably more expensive alternative because of the materials and the expertise required to install them.

Factors That Impact The Cost Of A Roof Replacement

One of the most important factors when trying to estimate the cost of a roof replacement is the size of your roof. The square footage of your home’s roof directly impacts the cost of the job. The more surface area that you need to cover increases the amount of materials and labor that is required.

Although it won’t give you an perfectly accurate estimate, knowing the surface area of your roof is good information to have when exploring your options for roof replacement services.

Roofing Materials

The types of shingles, roofing materials, and shingle design that you decide on will also be an important factor that will influence the overall cost of your roof.

Choosing between strip, dimensional, and luxury shingles will affect the cost per a square foot. On top of the design of the roofing shingles, the materials used, like slate, asphalt, or metal will also influence the budget of your roof replacement.

Building Permits, Inspections, & Warranties

Depending on where you live, certain communities require building permits for roof installation or roof replacements. Some roofing services provide free inspections, but others charge it along with the installation process. Building permits that are obtained from municipal authorities should be factored into the estimate for your roof replacement.

Some roofing services offer extended warranties that are separate from a standard roof warranty. Make sure to inquire what their warranty covers and how long it will last.

Roof Shape & Design

The architectural design or style of your roof will also influence the cost of a roof replacement project. If your roof has complicated slopes, multiple dormers, overhangs, vents, and other unique requirements, it will involve additional labor and skill making the roof cost increase.

Depending on whether the reason for replacing your roof is because of significant damage or that your roof has reached its lifespan will vary the overall cost of the replacement.

Water damage, structural damage, and rot can increase the labor required to make sure that the foundation of the roof is in good condition. The better condition that your existing roof is in the less your new roof installation or replacement will cost.
