Principle Roofing were responsive, competitive and friendly throughout the process. Dean and Sara gave us options that met our needs and the installation team lead by Sean was first class. They even accommodated our need for seasonal set up for our rain barrels.

Principal Roofing was fantastic to work with. Sara was amazing! Super helpful and easy to communicate with. Mike from the service team quickly inspected and fixed the leak in no time.

Our story

A Women-Owned Roofing Business.

I’m Sara Prince and the way I’ve succeeded in business is by providing ‘excellence-elevated’ customer service. As someone who owns multiple homes, I have had too many bad experiences with roofing contractors – jobs not finished, runaway costs, results that didn’t look right. I thought roofing was a sector that simply could be done better. So I started a roofing company with better ‘principles’:

  • Projects that don’t last weeks or months
  • No hidden fees or runaway costs
  • Clean-up that returns your property to the way it was when we started
  • An easy, stress-free experience for homeowners

FAQs

Roofing FAQs

A roof is something you only have to look after every once in a while and besides, it’s way up there hard to see so chances are, you have some questions. We, though, have been roofing every day for years and are happy to answer any question.

How do I choose a good roofing company?

The multitude of roofing company options in the saturated Toronto market makes choosing a reputable roofer a challenge for Aurora area homeowners. Look at past projects for poor practices like shingle racking and ridging roof bundles, shoddy workmanship like crooked valleys, and warranties as leaky as your old roof.

Read our danger signs that you haven’t picked a good roofing company, and the reasons why you should choose a roofing company local to the Aurora area.

What Sets Principal Roofing Apart from Other Roofing Companies?

Well, it starts at the top. Principal Roofing and Exterior Contractors is owned and operated by a woman who owns multiple homes. After many bad experiences with contractors — projects left unfinished yet paid for, and projects that “didn’t look right” when completed — Sara knew that something in the roofing sector needed to change, and that homeowners deserved to receive services from a roofing company that could be trusted to do high-quality work.

She has therefore created this business — from personal “bad” experiences — and has developed a top-quality service that you can trust. Our team of roofers is also comprised of many homeowners. They understand how costly repairs are and how stressful it can be to live through them. Our whole team works extremely hard each day to make the experience a pleasant one. This is the commitment that Principal Roofing and Exterior Contractors offers to all their clients.

What Warranties do you offer on your roof replacement services?

Each roof installation comes with a 10-Year Stress Free Labour Warranty. Mistakes can happen, though of course we strive for this not to be the case. If there is any issue whatsoever over the first 10 years, just call us, and we will be there.

We also offer extended warranties on the materials that we install. With the Preferred Contractor status through Owens Corning Canada, we can offer you the Lifetime Material Warranty, also known as the System Warranty. The installation and the materials will all have warranties, so you can rest assured knowing that your house is protected with your new roof.

What Warranties do you offer for your roof repairs?

On all roof and aluminum repairs, we offer a 60-day hassle-free warranty. Occasionally, leaks can be tricky to find. If the repair did not work the first time, just call us and someone will be there to keep investigating until we find the source.

Sometimes, Mother Nature is kind and we don’t get rain while in your 60-day warranty period. If there’s a problem, just call us and we will still attend for a re-visit. Our top 2 goals are client satisfaction and a leak-free roof!

Do you offer Roofing Financing?

Yes, we do! We offer 100% financing through iFinance Canada. Please see all the details and apply online at iFinanceCanada.com or by calling 1-888-689-9876.

A representative will be happy to answer all your questions and get your application started!

How much does a roof replacement project cost on average?

This is a bit of a complicated question to answer as there are so many factors to determine. The materials used, the roof’s size and pitch of the slopes, and accessories used for the project all affect how much it will cost to replace your roof or shingles.

As a trustworthy roofing company we provide very detailed estimates so that you can be aware of the costs. We also provide you with options because there is no “one roof for all”. Whether you are planning on staying in your house for the next 25 years or planning on selling next year will also factor into the decision-making on the type of roof you may want to install.
