Roofing Warranties Compared: By Manufacturer 5 Brands

A roof warranty is one of the most important documents you will receive after a new roof is installed, yet most homeowners have little idea what their warranty actually covers until they need to make a claim. Manufacturer warranties vary significantly across brands, including coverage length, what triggers a valid claim, how quickly protection starts to prorate, and whether the warranty transfers if you sell your home. Knowing these differences before choosing your roofing material can save you thousands of dollars and a lot of frustration down the road. Army Roofing installs products from some of the most trusted brands in the industry, and carries a 10-year workmanship warranty on every installation alongside any manufacturer coverage. Here is what this blog covers:

Warranty Terms Every Homeowner Should Know

Before comparing brands, it helps to understand the language that appears in every roofing warranty. These terms directly affect how much protection you actually receive.

• Limited Lifetime: Coverage lasts for the lifetime of the original homeowner on a single-family detached residence. For non-residential buildings or subsequent owners, the warranty period typically reduces significantly, often to 40 or 50 years at most.
• Non-prorated period: The initial window during which the manufacturer covers 100 percent of repair or replacement costs without reducing the payout based on shingle age. This is the most valuable phase of any warranty.
• Prorated coverage: After the non-prorated period ends, the manufacturer’s contribution decreases over time based on how long the shingles have been installed.
• Workmanship warranty: Separate from manufacturer coverage, this covers installation errors made by your roofing contractor. Army Roofing provides a 10-year workmanship warranty on all installations.
• Transferability: Whether the warranty can pass to a new homeowner when the property is sold, and under what conditions.

What Voids a Roofing Warranty

Understanding what can nullify your coverage is as important as knowing what is covered. The most common causes of voided roofing warranties include the following.

• Improper installation: Every manufacturer requires shingles to be installed according to their specific application instructions, including fastener type, nail count, and placement. Incorrect installation by an uncertified or careless contractor is the most common cause of voided coverage.
• Inadequate ventilation: All major manufacturers require proper attic ventilation as a condition of warranty validity. Poor airflow causes shingles to deteriorate faster, and manufacturers will deny claims when inspection reveals ventilation deficiencies.
• Use of incompatible products: Many enhanced warranties require a full system of the manufacturer’s own accessories, including starter strips, underlayment, ridge caps, and ventilation. Using a competitor’s products can reduce or eliminate enhanced warranty eligibility.
• Lack of maintenance: Gradual damage from neglected maintenance is generally excluded. Keeping gutters clear, addressing moss growth promptly, and scheduling periodic inspections helps protect both the roof and the warranty.
• Structural or consequential damage: Most manufacturer warranties cover the shingles themselves and do not extend to damage caused to the building’s interior, contents, or other systems as a result of a roofing failure.

Common FAQs for Ladner Homeowners

Warranty questions come up often, especially when homeowners in Ladner and the surrounding Lower Mainland are comparing quotes or trying to understand what they are actually purchasing. Here are the most common ones.

Does Army Roofing’s workmanship warranty cover installation errors?

Yes. Army Roofing provides a 10-year workmanship warranty on every installation, which covers errors made during the installation process, not just material defects. This is separate from and in addition to any manufacturer warranty on the shingles themselves. Manufacturer warranties typically cover defects in the roofing product; workmanship warranties cover how it was applied.

Should I register my roof warranty after installation?

Yes, and promptly. Most manufacturers require or strongly recommend warranty registration within a specific window after installation. Failure to register can limit your coverage, reduce transferability options, or disqualify you from enhanced warranty tiers. Army Roofing handles the registration process for customers as part of project closeout.

Does a roof warranty transfer when I sell my home?

All five brands Army Roofing carries offer some form of transferability, though the conditions differ. IKO, GAF, CertainTeed, and Malarkey each allow one transfer, typically requiring written notification to the manufacturer within a set window. Owens Corning charges a $100 transfer fee. In most cases, if the transfer occurs within the non-prorated period, the new owner receives the remaining balance of full coverage. If the transfer occurs after that period, coverage becomes prorated.

Does the warranty cover storm damage?

Manufacturer warranties are primarily designed to cover manufacturing defects in the shingles, not storm damage. Sudden storm damage is typically covered by homeowner’s insurance rather than the product warranty. Wind warranties within manufacturer coverage are specifically limited to cases where shingles blow off due to a manufacturing defect in the self-sealing strip, not general storm events. This distinction matters when deciding whether to file a warranty claim or an insurance claim after a weather event.
