Understanding Your Roof Warranty: What Canonsburg, PA Homeowners Should Know
When a new roof goes on, most homeowners hear the word “warranty” and assume they’re fully covered if anything goes wrong. In reality, roof warranties are more complicated than that, and understanding the fine print can save thousands of dollars if a problem shows up years down the road.
There Are Two Separate Warranties, Not One
The first mistake homeowners make is treating “roof warranty” as a single thing. In truth, every roofing project typically involves two distinct warranties that cover completely different risks.
The manufacturer’s warranty covers the shingles or roofing material itself. If the shingles fail due to a manufacturing defect, this warranty is what protects you. It comes from the company that made the product, not from the contractor who installed it.
The workmanship warranty covers installation errors. This one comes from the contractor and protects against problems caused by how the roof was installed, not the materials themselves. Leaks from improper flashing, poorly sealed valleys, or incorrect nailing patterns fall under this warranty, not the manufacturer’s.
Knowing which warranty applies to a given problem matters because filing a claim with the wrong party wastes time, and in some cases, missing a deadline on one warranty type can affect your ability to claim under the other.
Standard vs. Extended Manufacturer Warranties
Most asphalt shingles come with a standard limited lifetime warranty from the manufacturer, but the coverage isn’t equal across the board. Standard warranties often only cover material defects at full value for a limited number of years, after which coverage prorates down significantly. A shingle that fails in year 3 might be fully covered, while the same failure in year 20 might only get a small percentage of replacement cost covered.
Extended or enhanced warranties, which usually require using a certified installer and sometimes a full manufacturer-approved roofing system rather than mixed components, can offer stronger coverage, including labor costs for defect-related repairs. This is one reason we’re proud to hold Owens Corning Platinum Preferred certification, which unlocks stronger warranty tiers not available through standard, non-certified installers.
What Voids a Roof Warranty
This is the part most homeowners never think about until it’s too late. Several common situations can void or significantly limit warranty coverage.
Improper installation by an uncertified contractor is the most frequent issue, since manufacturers require specific installation standards to honor enhanced warranties. Skipping required components, like using a different underlayment or ventilation system than what the manufacturer specifies, can also void coverage even if the shingles themselves are installed correctly. Choosing the right shingle and system from the start matters here too.

Lack of proper attic ventilation is a lesser-known culprit. Many manufacturers require adequate ventilation as a warranty condition, since poor airflow can cause heat and moisture buildup that damages shingles from underneath, a failure mode the manufacturer won’t cover if ventilation specs weren’t met.
Unauthorized repairs or modifications, such as a homeowner or a different contractor patching the roof without following manufacturer guidelines, can also void remaining coverage on that section of the roof.
What to Keep After a Roof Installation
After a new roof is installed, homeowners should receive and keep several documents: the manufacturer’s warranty certificate, the contractor’s workmanship warranty in writing, and a copy of the installation invoice showing the specific products used. These documents matter if a claim needs to be filed years later, especially if the original contractor is no longer in business, since manufacturer warranties typically remain valid regardless of contractor status, but workmanship warranties often don’t transfer or survive a contractor closing shop.
Transferability
Some warranties, particularly workmanship warranties, are transferable to a new homeowner if the property sells within a certain window, which can be a selling point when listing a home. Manufacturer warranties are often transferable as well, though usually with a one-time transfer fee and a required notification within a set number of days after the sale closes.
Filing a Warranty Claim
If a problem develops, the first step is documenting it with photos and dates, then contacting the original installing contractor before reaching out to the manufacturer directly. A reputable roofer will help determine whether the issue falls under workmanship or material defect and guide the homeowner through the correct claims process rather than leaving them to navigate manufacturer paperwork alone.

Frequently Asked Questions
Does homeowners insurance replace the need for a roof warranty?
No. Insurance covers storm and accident damage, while warranties cover material defects and installation errors, which are two different categories of problems.
How long do typical roofing warranties last?
Manufacturer warranties on shingles are often labeled “lifetime,” though full coverage usually only applies for the first 10 to 15 years, after which it prorates. Workmanship warranties from contractors commonly range from 2 to 10 years.
Can I check if my roof warranty is still active?
Yes, most manufacturers let homeowners verify registered warranties online using the installation date and product line, or your original contractor can look it up on your behalf.
