How Much Does a New Roof Cost in Ontario?

Cost is an important consideration when replacing a major piece of your home like your roof. Below, see the average price range for roof replacement on a 1,500 square foot home in Ontario, as well as comparisons between different popular roofing materials.

How To Choose a Roofing Company

Installing a new roof is a large home improvement project that can cost tens of thousands of dollars. It's essential to research and find the most skilled and reliable roofing professional for the job. Here are some important factors to consider when choosing a roofing contractor.

  • Roofing materials and products: Quality roofing materials from leading manufacturers can handle Ontario's weather and last years. Watch out for contractors pushing cheap or generic materials. Check shingle samples before deciding.
  • Experience and credentials: Seek out providers that have been operating for a decade or more. These companies' extensive experience and time in operation reflects consistent work, knowledgeable teams, and happy former customers. Confirm that a provider has appropriate licenses, bonds, and insurance before hiring. Also inquire about professional certifications, such as those from the National Roofing Contractors Association.
  • Detailed written estimate: Trustworthy roofing companies will give you a comprehensive written quote. This proposal should outline the complete work plan, materials needed, and total price with no surprise fees. Steer clear of unclear quotes, or ones that seem much too low or high.
  • Responsiveness and communication: From estimate to project completion, your roofer should maintain ongoing communication with you, answer all questions, and address any concerns.
  • References and reviews: Check companies thoroughly by checking their latest online reviews on Google, Yelp, or the Better Business Bureau (BBB) and looking for consistently good feedback over many years. You can ask for recent local references to learn more.
  • Warranties and guarantees: Reputable roofing companies provide strong guarantees that protect your roof. Look for guarantees on shingles lasting 30+ years and at least a 5-year labor guarantee. Be wary of companies that have shorter warranties.

Signs Your Roof Needs Repair or Replacement

You may not think about your roof every single day, but it protects your home in important ways. Be aware of these common signals that your roof needs to be inspected and repaired by a professional roofer.

Roof Age

The age and material of your roof are key factors. Asphalt shingles, the most common residential roofing material, typically last around 20–25 years before needing replacement. If your roof is nearing or past this lifespan, have it evaluated to determine if full replacement is needed.

Leaks or Water Stains in Your Home

One of the clearest signs of a roof problem is leaking. Stains on ceilings, insulation, and walls — or in your attic — usually mean that water is seeping through damaged or worn shingles. Don't ignore small leaks, because even these can lead to mold growth and roof damage.

Exposed Roof Decking Underneath Shingles

Visible roof decking or sheathing under your shingles indicates that those shingles are severely curling or losing their seal. This means the shingles likely need replacement. Shingles need to lie flat to stop water from leaking into your home.

Cracked, Broken, or Missing Shingles

Inspect your shingles closely from a steady ladder or while on the ground. Look for shingles that are cracked or are missing granules. Storms can cause roof damage over time. To keep your roof in good condition, replace any missing shingles, or ones that are openly gaping.

Flashing Deterioration Around Roof Penetrations

Roof flashing protects valleys, vents, chimneys, and other areas that pass through the roof. If the metal flashing is cracked, peeling away, or completely worn out, it can leak. Have any flashing problems fixed right away.

Sagging Roof Line

If your roof sags or is uneven, get a roofer to evaluate it. These issues could signal a structural problem. A sagging roof that's not given adequate structural reinforcement or full replacement will deteriorate more over time.

Frequently Asked Questions About Roofing in Ontario, CA

The best type of roofing material for your home in Ontario will depend on a number of factors, including your budget and how often you're willing to do maintenance.

Asphalt is more budget-friendly, while materials like metal are more expensive but last longer. Clay roofing may be beneficial around Ontario due to its high solar reflectivity. Roofs of this type can help you save on cooling costs during the sunny summer months. You might be swayed by how environmentally friendly a material is, and opt for something like wood. If you live in a part of Ontario where the risk of wildfire damage is higher, choices like clay, metal, or treated wood might appeal to you.

In California, licensing is handled by the Department of Consumer Affairs Contractors State License Board. Contractors need an active license in order to work on roofing projects valued over $500, and in most cases must be bonded.

Roof replacement generally takes about one to five days. This timeline may be influenced by factors like the weather in Ontario, the accessibility of your roof, and its size. .

Your roof can impact the energy efficiency of your home. For example, a good roof allows you to use less energy to cool your home during the summer. Certain materials (such as metal) are more energy-efficient than others. In Ontario, you can reduce your carbon footprint even more by installing solar panels on your roof.

Your home insurance may cover some roof replacement costs if you use one of your insurance company's preferred contractors (if it has any). It may be easier to get some costs covered if the damage was caused by a covered weather event like a severe storm. You should reach out to your home insurance company to learn whether either of these situations apply to you.

After your roof installation, check the roof's appearance. If parts are sagging or the roof isn't uniform, this is a sign that the roof was not installed properly. Also, check that the flashing wasn't reused. Properly installed flashing is important to prevent leaks and water damage to your home. Finally, you'll want to check that your contractor placed an underlayment between the shingles and sheathing of your house. This helps prevent leaks and extends the life of your roof.
