What Homeowners Need to Know About Roof Warranties

When you’re buying a new roof from a trusted Frederick County roofing contractor, a warranty isn’t something extra, it’s part of the deal. But here’s the thing: not all warranties work the same way. It helps to know what’s actually covered and how to keep that coverage valid.

With over three decades of roofing experience, we’ve seen homeowners run into trouble simply because they didn’t know what their warranty covered, or didn’t. Many homeowners don’t realize that simple decisions, like letting someone unqualified handle small repairs, can accidentally void their warranty. 

Let us help you understand roofing warranties so you can avoid mistakes.

Types of Roof Warranties: Manufacturer vs. Contractor Warranties

You’ll usually come across two types: manufacturer warranties and contractor warranties.

Manufacturer warranties cover the materials, your shingles, underlayment, and maybe even things like vents or flashing. These warranties often last anywhere from 20-50 years, depending on the product you’re using. But here’s the thing: they usually only kick in if there’s a defect, something wrong with the materials themselves, not if it was installed incorrectly. So, if your shingles crack, curl, or fail because of how they’re made, that’s when the manufacturer steps in. We work with Owens Corning as a Preferred Contractor, which means you get top-quality materials and a longer warranty for greater peace of mind. 

Contractor warranties, on the other hand, cover the installation. That means if something goes wrong because of how it was put in, that’s where this warranty comes in.  At Topper Roofing, we guarantee our work with honest, clear warranties, so you’re never left wondering who’s responsible for what. We’re licensed and insured, and as a Preferred Contractor with Owens Corning, we can even offer extended warranty coverage that keeps you protected for years to come.

What’s Covered (And What’s Not)

Most manufacturer warranties cover:

  • Roofing material defect (like faulty shingles)
  • Certain time frames (some up to 50 years)
  • Full replacement or prorated coverage, depending on age

What they usually don’t cover:

  • Poor workmanship (that’s where contractor warranties matter)
  • Storm damage, falling trees, or foot traffic
  • Improper ventilation or maintenance problems

Contractor warranties often include:

  • Installation mistakes
  • Leaks due to workmanship
  • Usually for a set number of years after the roof is installed

Make sure to ask for a copy of both warranties in writing. You’ll want to know who to call when something goes wrong, and having it in writing avoids confusion later on.

How to Avoid Voiding Your Warranty

The truth is, some warranty mistakes happen without you even realizing it. Here are some of the most common reasons warranties get voided:

  • Trying DIY repairs or hiring unqualified help. It might seem cheaper at first, but it could cost you more in the long run. So always call a certified roofer like Topper Roofing.
  • Skipping annual inspections. Regular checkups can catch minor issues before they can turn into major problems.
  • Forgetting to register your warranty. Some manufacturer’s warranties require registration within a certain time frame.
  • Poor attic ventilation or insulation. These can wear down your roof faster than expected.

And here’s something we tell all our clients: when in doubt, just give your roofer a call. It’s always better to double-check than to void your coverage by mistake.

Bottom Line

Understanding your warranty now can save you a major headache and cost later. Nobody wants to be caught off guard by a repair bill they thought would be covered.  Keep a copy of your paperwork, ask questions, and work with someone you trust to do the job right from day one.
