What to Look for When Hiring a Roofer?

Your roof protects you and your family from the elements, so it’s important that you choose the best professional roofers Ottawa has to offer. But how do you choose? Here are a few things to look out for when deciding to hire a roofing company:

Liability Insurance and WSIB Coverage

A professional roofing contractor will have insurance coverage, particularly liability insurance and workers’ compensation. Otherwise, you could be held liable for damages to your property that the roofing company caused as well as for personal injury to the roofers.


Any professional roofing contractor should be an accredited member of the Better Business Bureau. Check and see how long they have been registered and what their rating is.

Open Communication

Ask your roofer about materials they will use, process, cost, clean-up, and see how openly they communicate with you regarding your project. If they aren’t able to answer your questions with clear answers, then they may not be a contractor you should be doing business with. Poor communication can lead to misunderstandings, unwelcome surprises, and a substandard final product.

Get It in Writing!

Ask for a written contract with the total estimated cost for your roof. This keeps your roofer accountable and ensures they stick to the project specifications.

The Benefits of Repairing Your Roof

You might be neglecting your roof damage, hoping that the problem might go away on its own. However, not only will this worsen the issue, but it is a safety hazard. There are many reasons to repair your roof, such as:


Improved Insulation: With a newly repaired roof, you don't have to worry about air leakage from your roof.

Enhanced Security: A broken roof can damage your property or harm your property's occupants. You can prevent this with timely roof repairs.

Improved Property Values: A fully functional roof with no damages directly translates into higher property values.

Money Savings: Ignoring your roofing issue can aggravate the problem, forcing you to spend more money in the long run.

Better Appearance: A neglected roof will leave a poor impression on your clients and visitors. A freshly repaired roof, on the other hand, will improve your property's curb appeal.
