A new roof is one of the biggest investments you’ll make in your home, so it’s only natural to expect long-lasting protection and peace of mind. Yet for many homeowners, roofing warranties remain one of the least understood parts of the process. What’s covered, what isn’t, and how can you be sure your warranty will actually protect you if something goes wrong?
At JN Roofing, we believe that clarity builds confidence. This guide will help homeowners in Barrie, Simcoe County, Muskoka, and Parry Sound understand how roofing warranties work, what sets Owens Corning Platinum Preferred coverage apart, and how proper maintenance keeps your protection strong for years to come.
Understanding Roofing Warranties
A roofing warranty is more than a piece of paper—it’s a promise of protection. But not all warranties are created equal. Many homeowners assume a warranty covers everything, when in reality, the type of warranty determines what’s protected and for how long.
At a high level, there are three main roofing warranties: manufacturer warranties, workmanship warranties, and extended or enhanced system warranties. Each one plays a different role in your long-term roof protection.
Types of Roofing Warranties
Manufacturer Warranty
This warranty is offered by the roofing material manufacturer and typically covers defects in the shingles themselves. For example, Owens Corning’s standard warranty ensures that your shingles are free from manufacturing defects that could cause premature failure.
However, it’s important to note that this warranty usually does not cover issues related to improper installation or storm damage. It’s designed to stand behind the product, not the workmanship.
At JN Roofing, we also handle the registration of your Owens Corning warranty on your behalf, ensuring your manufacturer coverage is properly activated.
Workmanship Warranty
A workmanship warranty is provided by the roofing contractor and covers the quality of the installation. If a roof leak or issue arises because of installation errors, this warranty ensures that your contractor will make it right.
At JN Roofing, our workmanship warranty reflects our commitment to excellence. Every roof is installed by certified professionals trained to meet the highest industry standards. This coverage offers homeowners confidence that their investment is protected not only by the materials but also by the skill behind the work.
Extended or Platinum Coverage
Some contractors can offer extended coverage through their manufacturer partnerships. JN Roofing’s Owens Corning Platinum Preferred status allows us to provide the most comprehensive protection available, combining both material and workmanship warranties into one powerful package.
What’s Covered (and What’s Not)
One of the biggest sources of confusion for homeowners is what a roofing warranty actually includes.
Covered items typically include:
- Manufacturing defects in shingles or roofing components
- Workmanship errors when covered under the contractor’s or Platinum warranty
- Full system coverage when all qualifying materials are installed by a certified contractor
Not typically covered:
- Damage caused by severe weather such as hail, windstorms, or falling trees
- Problems resulting from improper maintenance or alterations by an unapproved contractor
- Natural ageing or minor aesthetic variations over time
While no warranty can prevent nature from taking its course, Owens Corning shingles are engineered for durability and tested to withstand the harsh conditions that Canadian homes face year after year.
JN Roofing’s Platinum Preferred Protection
Being an Owens Corning Platinum Preferred Contractor is not a title given lightly, it represents the highest standard in roofing craftsmanship and customer care. Fewer than one percent of roofing companies in Canada achieve this level of recognition.
Through our Platinum Preferred status, JN Roofing offers homeowners exclusive access to Owens Corning’s strongest warranty, providing lifetime coverage on shingles, labour, tear-off, and disposal. The warranty is also transferable once, which means if you sell your home, the next homeowner can enjoy continued protection, adding real value to your property.
This level of protection isn’t available through most contractors, and it’s one of the reasons so many homeowners across Simcoe County and Muskoka trust JN Roofing to handle their roof replacements with confidence.
Registering and Maintaining Your Warranty
Even the best warranty can fall short if it’s not properly registered or maintained. After your roof installation, make sure to complete your warranty registration with Owens Corning and keep copies of all documents and receipts for future reference.
To maintain full warranty coverage, it’s important to:
- Schedule periodic roof inspections, especially after severe storms
- Keep your roof clear of debris and ensure proper attic ventilation
- Avoid unauthorized repairs or modifications
- Contact JN Roofing for any maintenance or warranty-related questions
Taking these steps helps ensure that your roof remains in excellent condition and that your coverage stays valid for the long term.
