"How much will my roof repair cost?" is the first question almost every homeowner asks us. The honest answer is that it depends on what's failing, how much of the roof it affects and what's underneath. Resealing a vent boot and replacing a rotted section of roof deck are both "roof repairs", but they're very different jobs.
Here's what drives the price of a roof repair, and how to read a repair quote so there are no surprises.
The Cost Is Proportional To The Quality Of Materials Used
The first thing we tell homeowners is to pay close attention to the materials a quote includes. Higher-quality shingles, membranes, flashing and underlayment cost more, and they're a big part of the price difference between two quotes. Material prices also change over time, so a quote should always reflect current costs.
In addition, it is important to note that roofing contractors such as us will charge more for certain materials- depending on the number of labour hours required to install them as per the manufacturer's recommendations. For example, when we are reinstalling flat roofs versus shingles- we take into account the additional material required (the flat roof membrane and the number of plies on the membrane required for the job).
Price Per Square Foot Is Only A Starting Point
When working out the cost of a roof repair, bear in mind that a price per square foot (or per roofing square) is a useful starting point for budgeting. But because there are so many variables at play, such as the quality of materials and the condition of the roof deck, we advise getting a detailed written scope of work and price after a site visit or drawings review. This keeps the guesswork out of pricing and ensures you have no surprises.
- Make sure they give you a detailed scope of work for what is included in the price
- Ensure that if new architectural drawings are required that your contractor confirms that they have received them and will follow them
- Ensure your contractor is aware of any Ontario Building Code or Hamilton Municipality bylaws/limits
Cost Is Also Proportional To Quality Of Work
You have to also remember that “You get what you pay for”. There is a lot of competition for roofing work, and the lowest price often means corners are cut somewhere. It is important to bear in mind, however, that at Ontario Tech Roofing, we do not believe in competing for the cheapest, most economical contractor. Our focus on every job is to:
- Provide the best quality service
- Provide the best quality equipment to make sure our workers are safe and secure on your job site
- To make sure the homeowner is satisfied and that your most important asset is protected
When you're collecting roof repair quotes, ask for references and photos of similar work, and check reviews before you decide. Also feel free to contact us if you are looking for a quote!
Should You Repair or Replace?
A repair makes sense when the damage is limited to one area and the rest of the roof still has years left. If the shingles are curling or losing granules across the roof, you've had several leaks, or the roof is near the end of its life (around 20 to 30 years for asphalt shingles), a full roof replacement is often the better value. For typical price ranges, see our roof replacement cost guide.

Frequently Asked Questions
Why do roof repair quotes vary so much?
Usually because they don't cover the same work. One quote may include replacing damaged decking, new flashing and disposal while another doesn't. Compare the written scope line by line, not just the total.
Can a roofer give me a price over the phone?
A roofer can sometimes give a rough range, but an accurate price needs someone to look at the roof. Problems like soft decking or failed flashing aren't visible from the ground or in photos.
Is it worth repairing an old roof?
If the problem is isolated and the roof has a few good years left, a repair can be worth it. If the roof is near the end of its life, repair money is often better put toward a replacement.
Does a roof repair come with a warranty?
A reputable roofer will put a workmanship warranty in writing. Ask how long it lasts and exactly what it covers before the work starts.
