This was top notch work done over a year ago. I can now attest to the fact that with the 25 year Hurricane rated resistant shingles , they haven't budged even with the high winds southern Ontario experienced this past summer.They also added eavestrough leaf stoppers so don't get any more blockage in heavy rain which just permits the rain to enter eaves. I've used 2 other companies in past 30 years but these folks did the most satisfactory work. Hard to find dedicated workers like this nowadays.

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

And now I’m backed by a client-care specialist who prides herself on time management and clear communication with our customers and, because experience is important when it comes to roofing work, each roofer team with a minimum 40 years experience each. All our roofers are hand-picked for the skill and beauty of their workmanship and their meticulous work standards. I’m proud of them and the accolades we’ve been getting from customers and the industry.

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.
What Sets Your 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 it was 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. Sara understands the hardships that homeowners go through when trusting a contractor with projects around their home.

She has therefore created this business– from personal “bad” experiences–and has developed a top-quality service that you can trust. A roofing or eavestrough project should not last weeks or months. They should not go over budget. They should be an easy project to complete. They should be properly installed the first time around and your property should be returned to the exact state of how it was found when the project started. This is what we do!

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. We are also able to offer the Preferred Warranties as well! 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 or by calling 1-888-689-9876.

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 re-roof or re-shingle a house. 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”. In addition, whether you are planning on staying in your house for the next 25 years or if you are planning on selling next year will also factor into the decision-making on the type of roof you may want to install.

Where do you purchase your materials from?

Principal Roofing and Exterior Contractors knows where to source the best quality materials using a locally-owned supplier, Gibson Building Supplies. They offer a fantastic service and the best part is that your shingles are stored inside their warehouse prior to being installed on your roof–this means they are not outside facing the elements for months and are not going through freeze-and-thaw cycles before being installed on your roof.

With long-lasting materials using the Owens Corning Tru Definition® Duration Shingles or BP Canada Shingles made right here in Canada, we ensure that we are providing you with the best service and value for your roofing project.

How much does roof replacement add to the property’s value?

One of the first things a potential home buyer will see before entering a property is the roof. This creates curb appeal and shows that the house has been maintained. A buyer will not have to factor in the cost of a roof replacement in the near future and will look at this as favourable.
An inspection of the roof by an expert is necessary to gauge the quality of the roof. The damages, if not fixed, will lower the value and might even cause the buyer to back out of the deal if they have to pay for pricey roof upkeep and repairs. A leaking roof can also cause mold in the inside of the house, which can be very costly to remedy. This can completely turn off buyers from purchasing your property.

A well-maintained house will always win the hearts of buyers over ones that need major repairs.

What are the prices of different roofing materials used?

Depending on the quality and type of materials, the rates per square range from $360 to $2,185. Steel Roof, Composite, Slate and Cedar would be at the top end. The least expensive is typically asphalt shingles which costs between $350 and $1000 per square or 100sqf, depending on the style of roof.

With long-lasting roofing materials using the Owens Corning Tru Definition® Duration Shingles or BP Canada Shingles made right here in Canada, we ensure that we are providing you with the best service and value for your roofing project.

Is it necessary to replace all the roofing shingles or can we just do a portion of the house?

We do recommend replacing all of the shingles on your home if it is within budget. The reason we recommend this is that if you do not, you will not qualify for the extended manufacturer warranties that we offer through Owens Corning Canada or BP Canada.

If this is not a factor in your decision to just do a portion of your house, then yes, we can accommodate this request!

It is best to have your roof inspected to determine what the best route is if your desire is to do only half the house. A skilled roofer can conduct a thorough roof inspection to determine the best course of action.

Is a roofing permit necessary for a roof replacement project in York Region?

No permit is necessary if you are just removing shingles and re-applying them. However, if you are making structural changes or repairs to your trusses, then yes, a permit is required.
A parking permit might be required if you need to park on your street for the duration of your project. These can usually be obtained for a small daily fee from your municipality website.

Do we Subcontract?

Absolutely we do! We are not shy about it either. We are, however, extremely picky with our subcontractors.

The companies chosen to represent Principal Roofing and Exterior Contractors, are skilled tradesmen who are also business owners. This is not a bad thing if you choose the subcontractors correctly.

Business owners take pride in their work, they train their team to our standards and they know that their work will be inspected by our Project Manager.

The subcontractors that we choose uphold our high standards. We also ensure that they have WSIB and Insurance up to date at all times.

Our promise to you is that we will only send the best to work on your home.
