What Do Gutter Guard Warranties Really Cover?

Have you been told your gutter guards come with a “lifetime warranty,” but it’s not your first time getting fed a slick marketing line? You’re rightly wondering about what that really means when something goes wrong. Have you (or someone you know) been burned by warranty fine print in the past and want to avoid repeating that mistake? 

You’re not alone in feeling confused or skeptical. Many homeowners are shocked to find out what their gutter guard warranties don’t cover, especially in a rainy, needle-filled climate like Seattle.

At RoofSmart, we’ve installed or replaced hundreds of gutter guards, meaning that we’ve had plenty of opportunities to help our customers understand their options for dealing with damaged gutter guards (hint: most of the time, they aren’t eligible for warranty coverage). 

In this article, we’ll break down what gutter guard warranties usually do and don’t cover, what exclusions you need to watch out for, and how to tell whether a warranty is truly worth it so you can make a smart, confident decision before you buy.

What does a gutter guard warranty cover?

Gutter guard warranties typically cover manufacturing defects with the product, which will prevent clogs in your gutter if you use the gutter guard “properly”. You can probably already sense the caveats. “Properly” is pretty subjective.

Depending on the material the gutter guard is made of, the defect warranty will likely protect against things like

• Rusting
• Cracking 
• Chipping

These issues are pretty rare in the Seattle area. Cracking or chipping usually only happens if the gutter guard is hit by something, which doesn’t happen often. In fact, I’ve been doing this for over 20 years, and I have never seen cracking or chipping on a gutter guard. 

In that scenario, it would probably dent and then be excluded from coverage (which we have seen happen). 

The most common gutter guard issue we see in the Seattle area is clogging of THE GUARD ITSELF, not the gutter. The constant rain and shedding of pine or fir needles means that there’s always debris trying to get into your gutter. What you care about is the PERFORMANCE warranty. That’s what you’re buying. 

Here’s an example of a broken expectation with K Guard. There are plenty of similar examples:

The INSIDE is not plugged. But with water skipping off the front lip of the hood, the guard is not functioning due to “lack of maintenance.”

If the inside of your gutters ends up clogging, you might have a few different options depending on what kind of coverage the manufacturer offers. You can choose to:

• Repair or replace gutters: If your gutter has some sort of material defect (like rusting or chipping), you can call in the manufacturer to repair the problem.
• Get a refund: Most gutter guard warranties will offer you a money-back guarantee if the gutter guard fails. This means that if your gutter clogs while using a gutter guard, the manufacturer would refund you for the cost of the gutter guards.
• Have them clean out the gutters: Another common option is that the gutter guard company will offer to clean out the gutters, but again, only if the INTERIOR of the gutter (like the downspout) is clogged. 

But usually it’s a performance problem. The gutter guard worked when it was new, but now it’s dirty and clogged, which is causing issues. This is not covered by the warranty.

Here’s what you can expect from each company: 

• Leaf Filter: Offers to repair problems caused by overflowing gutters or refund you 100% of the MATERIAL PURCHASE PRICE of the gutter guard (you get no compensation for labor costs). 
• MasterShield: They’ll replace or refund you for the cost of installing MasterShield on your house. They’ll also refund your insurance deductible (up to $1,500) if the gutter clog causes damage to your house that requires you to file a claim with your homeowner’s insurance. 
• Gutter Helmet: They will repair, replace, or refund you for the cost of the gutter guard (again, this is only for materials; you won’t get a refund on labor costs).
• Leafguard: If there is a defect or gutter clog, they will repaint, repair, or replace the gutter guard and cover 100% of the costs. 
• K Guard: The warranty statement on their website is pretty vague. They guarantee that there will be no problems with the product or with workmanship, but say that they will fix issues at their discretion. K Guard actually doesn’t have a warranty for their product. They do all of the warranties through whoever is selling the product: 

What’s excluded from a gutter guard warranty?

Gutter guard warranties sound pretty great until you read up on what is excluded. But the key point to remember here is what they’re guaranteeing: gutter guards are meant to prevent clogs in your gutter, but the warranty will not cover clogs in the actual gutter guard. 

That’s a maintenance item. In my experience, their salesmen do not disclose this.

Here’s what the gutter guard warranty won’t cover:

• Damage from clogged gutter guards: Gutter guard companies expect you to keep up with maintenance. This is inherently reasonable. It means that you’ll need to clean off the gutter guards every once in a while to make sure that they don’t clog and overflow (potentially causing water damage to your home’s roof or foundation). If you’re a Seattle resident, this means removing pine or fir needles and leaves before they build up too much. Or algae slime. That’s the black sludge-looking stuff.

• Labor to repair or replace gutter guards: If your warranty offers coverage or a refund to replace defective gutter guards, this probably only includes material costs. Some companies exclude the cost of labor from their warranty coverage, meaning that you are responsible for that cost (or you don’t get it back in a refund). Due to the high cost of living in the Seattle area, labor costs are also pretty high. This means you’ll have to pay labor costs to replace the gutter guards or, if you choose the refund, you don’t get that money back. For example, LeafFilter famously has a 100% money-back warranty. When reading the actual warranty language, though, it says 

• The dealer’s material purchase price is approximately $1.50 per foot on that product. With a system that retails for $30/ft, you can see the problem.

• Damage from natural disasters: If your gutter guards get damaged in a storm, this won’t be covered by the warranty. If, for example, they get hit by a branch, you might be able to make an insurance claim, but the warranty won’t be able to help you. Windstorms do happen sometimes in the fall and winter in Seattle, so it’s possible that the gutter guards might get damaged. 
• Accidental damage: If your gutter guards get accidentally damaged while you or someone else is cleaning them (or working on your roof), then that won’t be covered by the manufacturer. Some gutter guard warranties can even be voided if you lean a ladder against the gutter 

• Poor or improper installation: Some gutter guard warranties do not include coverage for workmanship issues. This means that if your gutter guard is overflowing, clogging, or otherwise not working right because it was installed incorrectly, then you’ll have to take that up with the installer. Hopefully, you got a workmanship warranty from them. 
• Normal wear and tear: This is a pretty standard exclusion in almost any warranty (even for things that aren’t related to the roof). It’s expected that the gutter guards will wear out over time as they are used, but this shouldn’t impact how they function. 

How do I know if a gutter guard is worth it, considering these misleading warranties? 

If we’re being totally honest here, a lot of gutter guard warranties don’t offer great coverage. On the surface, they sound really awesome, but when it comes time to call in coverage, you’re hit with a long list of exclusions. Let’s see them for what they are: they’re just sales tools.

So, what can you do to make sure that your roof and gutters are protected? 

1. Understand what the warranty does and does not cover: Being informed about what is and isn’t covered will help you avoid nasty surprises if you ever end up needing to use the warranty. Make sure you read the warranty carefully before agreeing to purchase the gutter guards. Don’t be afraid to ask the manufacturer clarifying questions. If they don’t give you a straight answer or try to direct you away from the warranty, I’d recommend staying away from that company. 
2. Look for a workmanship warranty: Installation errors are more likely to happen than material defects, so a strong workmanship warranty is a great thing to have. Find out who will be installing the gutter guards and see if they offer a workmanship warranty. It will either be an installer that the manufacturer subcontracts out or a local installer who sells the gutter guard for the manufacturer. If it’s a local company, look them up and see if they seem reputable and trustworthy. Ask either the manufacturer or the installer if they’ll provide a workmanship warranty. Make sure you read it carefully and ask the installer any questions that you may have. 
3. The performance warranty and the track record of the local installer are very important. They will show you if the gutter guard is even worth getting. 
4. Clean your gutter guards: Although gutter guards do reduce the amount of maintenance your home needs, you still have to clean them off every once in a while. Make sure you inspect your roof and clean off any areas where debris it building up. That way, you’ll avoid clogs that cause water damage to your roof or foundation. Also, if you do end up needing to use your warranty, they can’t immediately deny it because the gutter guards weren’t cleaned properly. 

Which gutter guard style works best for homes in the Seattle area?

Now that you know what gutter guard warranties do (or don’t) cover, it’s clear that choosing the right product from the start matters more than relying on a warranty to save you later. A warranty won’t prevent clogs, overflow, or damage. It only helps after things go wrong (and even then, not always).

So if you’re serious about protecting your home, the next step is to choose the right style of gutter guard for Seattle’s constant rain, fir needles, and seasonal storms.
