When homeowners begin comparing roofing quotes, most focus on three things: price, shingle colour, and warranty. While those are all important, they often overlook the factor that has the greatest impact on how long a roof lasts, the quality of the installation.
A roof isn’t simply a layer of shingles nailed to a house. It’s a carefully engineered system designed to manage water, resist wind, control moisture, and protect your home through decades of changing weather. Even premium roofing materials can’t perform as intended if they’re installed incorrectly.
That’s why manufacturer certification programs exist.
If you’re replacing your roof in Fredericton or anywhere in Central New Brunswick, understanding what it means to hire a BP Certified Roofing Installer can help you make a more informed decision and potentially avoid costly problems years down the road.
What Is BP?
BP (Building Products of Canada) is one of Canada’s oldest and most respected manufacturers of residential roofing products. Founded in 1905, the company has spent more than a century developing roofing systems designed specifically for Canadian climates.
Their product line includes:
- Architectural asphalt shingles
- Ridge cap shingles
- Starter strips
- Underlayments
- Ice and water protection
- Ventilation accessories
- Complete roofing system components
Unlike roofing products designed primarily for warmer regions, BP products are engineered with Canadian weather in mind. That’s particularly important in New Brunswick, where roofs experience significant snow loads, freeze thaw cycles, wind driven rain, ice buildup, and dramatic seasonal temperature swings.
Choosing quality roofing materials is important. Installing them correctly is even more important.
What Does “BP Certified Roofing Installer” Actually Mean?
A BP Certified Roofing Installer is a roofing contractor who has met BP Canada’s standards for installing its roofing systems.
Certification demonstrates that a contractor has invested time in understanding manufacturer recommended installation methods, product specifications, and roofing system best practices.
It’s important to understand what certification does and doesn’t mean.
It doesn’t mean every uncertified roofer performs poor work.
Likewise, certification alone doesn’t guarantee a perfect installation.
Instead, certification demonstrates a commitment to continuing education, following manufacturer guidelines, and installing roofing systems according to recognized best practices.
For homeowners, that’s an important signal when comparing contractors.
Why Installation Quality Matters More Than the Brand of Shingles
One of the biggest misconceptions in residential roofing is that shingles determine how long a roof lasts.
In reality, the roofing system is only as strong as its installation.
Imagine two identical homes in Fredericton.
Both receive the same architectural shingles.
Both experience the same winters, the same storms, and the same summer heat.
Twenty years later, one roof is still performing well while the other has required multiple repairs.
Why?
Very often, the difference isn’t the shingles.
It’s everything underneath them.
A roofing system depends on dozens of installation details that most homeowners never see after the project is complete.
These include:
- Roof decking preparation
- Ice and water membrane placement
- Underlayment installation
- Flashing details
- Ventilation design
- Fastener placement
- Starter strip installation
- Ridge ventilation
- Ridge cap installation
Every one of these components contributes to how the roof performs over the next two or three decades.
As experienced roofers often say:
“A roof doesn’t fail because one shingle was installed incorrectly. It fails because dozens of small installation details gradually allow water to find a path inside.”
Why Manufacturer Certification Exists
Manufacturers invest enormous resources developing roofing systems.
Every layer is designed to work together.
The underlayment supports the shingles.
The flashing protects vulnerable transitions.
The ventilation controls moisture and temperature.
The ice and water membrane protects areas where snow and ice commonly accumulate.
Certification programs exist because manufacturers understand that product performance depends on proper installation.
When roofing systems are installed according to manufacturer recommendations, homeowners are far more likely to receive the long term performance those products were designed to deliver.
Why Proper Installation Matters Even More in New Brunswick
Roofs in Atlantic Canada face challenges that many other regions simply don’t experience.
Throughout the year, a typical roof in Fredericton may experience:
- Heavy snow accumulation
- Freeze thaw cycles
- Ice dam formation
- Wind gusts exceeding 100 km/h during major storms
- Driving rain
- Rapid spring temperature swings
- High summer humidity
These conditions constantly test every component of a roofing system.
For example, flashing that performs adequately in a mild climate may become vulnerable after years of expansion and contraction caused by freezing temperatures.
Likewise, poor attic ventilation can contribute to moisture buildup during winter, increasing the likelihood of ice dams and shortening the lifespan of roofing materials.
That’s why installation quality becomes especially important in climates like New Brunswick.
A roof installed to minimum standards may perform adequately.
A roof installed according to best practices is more likely to perform consistently for decades.
Certification Reflects a Commitment to Professionalism
Roofing certification isn’t simply about learning how to install shingles.
It’s also about maintaining professional standards.
Homeowners should expect their roofing contractor to demonstrate:
- Knowledge of current installation practices
- Attention to detail
- Ongoing product knowledge
- Safe work practices
- Professional communication
- Pride in workmanship
Certification complements these qualities by demonstrating that a contractor values continued learning rather than relying solely on experience gained years ago.
The roofing industry continues to evolve as manufacturers introduce new products, updated installation methods, and improved roofing technologies.
Contractors who continue learning are generally better positioned to install those systems correctly.
Certification Is Only One Part of Choosing the Right Roofer
While manufacturer certification is valuable, it should never be the only factor homeowners consider.
The best roofing contractors combine certification with local experience, transparent communication, and a strong reputation within the community.
When comparing roofing companies, ask questions such as:
- How long have you been installing roofs in New Brunswick?
- Are you licensed and insured?
- Do you carry liability insurance and Workers’ Compensation coverage?
- What type of ventilation improvements do you recommend?
- Will damaged roof decking be replaced if it’s discovered?
- What warranties are included?
- Can you provide local references?
The answers often tell homeowners far more than the price printed at the bottom of the estimate.
Common Misconceptions About Roofing Certifications
Because certification programs aren’t widely understood, homeowners often make assumptions that aren’t entirely accurate.
“Certified means the roof will never have problems.”
No roofing system is immune to weather, aging, or unexpected circumstances.
Certification simply indicates that the contractor has demonstrated knowledge of manufacturer recommended installation practices.
“Certification only benefits the contractor.”
Certification benefits homeowners by providing another measure of confidence when evaluating roofing companies.
It’s evidence that the contractor has invested in professional development rather than treating roofing as simply another construction job.
“Any roofer installs shingles the same way.”
This is one of the most common misconceptions.
Experienced roofing professionals know there are dozens of details that influence long term roof performance.
Two roofs may look identical from the street while being installed very differently beneath the surface.
Many of the most important components are completely hidden once the project is finished.
Choosing a Roofing Contractor Is About Trust
For most homeowners, replacing a roof is something they’ll only do once or twice during their lifetime.
That makes choosing the right contractor just as important as choosing the right shingles.
Rather than asking:
“Who’s the cheapest?”
A better question is:
“Who is most likely to install a roofing system that will still be protecting my home twenty-five years from now?”
The answer usually comes from evaluating experience, workmanship, certifications, reputation, communication, and a contractor’s willingness to explain their recommendations, not simply from comparing prices.
Conclusion
A roofing system is one of the hardest working parts of any home. It protects everything beneath it, often through decades of harsh weather, changing temperatures, and seasonal storms. While premium roofing materials play an important role, they’re only one part of the equation.
Choosing a contractor who understands how an entire roofing system works, and who follows manufacturer recommended installation practices, can make a meaningful difference in the long term performance of your roof.

Frequently Asked Questions
A BP Certified Roofing Installer has demonstrated knowledge of BP Canada's product systems and installation best practices. Certification indicates the contractor has invested in professional development and follows manufacturer-recommended methods — which can affect both the warranty you receive and the longevity of your roof.
No certification can guarantee a roof will never experience issues, since weather, aging, and unforeseen circumstances all play a role. However, certified installers have demonstrated a commitment to proper installation practices, which significantly reduces the risk of problems caused by installation errors.
Certification doesn't automatically mean higher prices. The most important factor is the overall value offered — quality materials, proper installation, clear communication, and a solid warranty. In many cases, investing in a qualified contractor costs less over the long term than dealing with repairs from poor workmanship.
Ask the contractor directly for proof of certification, and don't hesitate to contact BP Canada to confirm. Reputable contractors are transparent about their credentials and can provide documentation when asked.
Even the highest-quality shingles underperform when installed incorrectly. A roofing system depends on dozens of installation details — flashing placement, underlayment, ventilation, fastener spacing — that are invisible once the roof is complete. Poor installation in any of these areas can allow water infiltration long before the shingles themselves fail.
