The Truth About Roofing Warranties: What’s Covered and What Isn’t

You’ve got two estimates sitting on the kitchen table. Both of them promise a lifetime roofing warranty somewhere on the page. One is four thousand dollars cheaper. And there’s no honest way for you to tell, from those two pieces of paper, which roof is actually protected and which one just has a nice word printed on it.

I’m Craig Stafford with Holthaus Roofing. I am the steep slope manager, so I handle our residential roofing projects here in Canton from start to finish. A roofing warranty is probably where I see homeowners get surprised the most, and usually it isn’t because a contractor lied to them. It’s because the word warranty covers about four different things and nobody stops to say which one they mean.

I spent years as an insurance adjuster before this, so I read policy language for a living. Warranty paperwork is written the same way. Generally the part that decides whether you get paid is not the part in the big print.

So let me slow down and define the terms, and then I’ll tell you exactly what we can register on a roof here in Fulton County, including where our own offer stops.

Every Roof Has Two Warranties. Most Homeowners Only Hear About One.

There are two separate promises on a new roof, and they come from two different places.

Number one is the manufacturer warranty. That comes from whoever made the shingle, and it covers the shingle itself being defective. If the product fails because of how it was made, that’s on them.

Secondly there’s the workmanship warranty. That comes from the contractor, and it covers the installation. Nails in the wrong place, flashing that wasn’t tied in right, a valley done poorly, penetrations sealed in a hurry, and so forth.

	Manufacturer warranty	Workmanship warranty
Comes from	Whoever made the shingle	The contractor who installed it
Covers	A defective shingle	The installation — nailing, flashing, valleys, penetrations
What actually goes wrong first	Rarely the shingle	Usually this
Only as good as	The manufacturer	The contractor still being in business

Here’s why that difference matters. Generally, in the first ten or fifteen years of a roof’s life, the problems we get called out to look at aren’t defective shingles. Shingles from a real manufacturer are a manufactured product with quality control behind them. What we usually find is installation. So that’s the part you’re actually exposed to, and the manufacturer warranty doesn’t cover it.

So when a bid waves a fifty-year warranty at you and doesn’t separate those two things out, that fifty-year number is describing the part that was least likely to give you trouble in the first place. Which is why vetting the installer matters more than the number on the brochure. We wrote up what to look for in a licensed roofing contractor separately, and it’s worth ten minutes before you sign anything.

Where Lifetime Stops Meaning Lifetime

Lifetime is a real term with a specific definition, and it’s narrower than it sounds. Generally it applies to the individual owner living in the home as a residence. Put that same shingle on a rental property, or hold the house in an LLC or a trust, and the coverage period drops to a set number of years instead.

The bigger thing to understand is prorated versus non-prorated. A prorated warranty pays you a percentage based on how much life the roof had left. Twenty years into a thirty-year roof, a prorated claim isn’t going to buy you much. A non-prorated warranty covers the full cost of replacing the defective material for the whole stated period, with no depreciation math.

The Labor Gap Nobody Mentions

This is the one that costs people real money, so I want to be plain about it.

A lot of warranties cover material only. Meaning if a shingle is found defective, what you receive is shingles. Not the labor to tear off the failed roof, not the disposal, not the crew to put the new material on. On a re-roof, labor is a large share of the total. So a material-only claim can leave you holding most of the bill on a roof you were told was covered.

This is the part I spend the most time on at kitchen tables. Nick puts it about the same way:

Something customers really need to look at is the warranty of the roof being offered, and where that warranty is coming from. We highly recommend you’re getting your roof warranties from the roof manufacturer, not just from a contractor. A lot of contractors are offering material-only warranties with a workmanship warranty backed by the contractor. If you’re able to get something where the manufacturer covers labor and material both, that’s typically a much better system.

That last part is the whole point. A workmanship warranty backed by the contractor is only worth as much as the contractor, and that includes ours. If a company closes up shop or moves on, the promise leaves with them. This is the practical problem with the crews that come through town after a hailstorm. Usually the shingles weren’t nailed on correctly to begin with, probably because they were in a hurry to get to the next roof, and by the time the leak shows up there’s nobody left to stand behind the work. We see the aftermath of that on storm damage repairs a year or two later. When the manufacturer is carrying the coverage instead, it doesn’t depend on anybody still being in business.

What We Can Actually Register on a Canton Roof

Here’s where I can quit talking in generalities and tell you what’s on the table with us specifically.

Holthaus Roofing is a CertainTeed ShingleMaster PREMIER contractor, which is their current top credential tier, and we’ve been credentialed with them since 2010. What that means practically is that we’re able to register CertainTeed’s SureStart PLUS 5-Star warranty on jobs that qualify, and we do register it.

On a qualifying single-family detached home, that coverage is:

• 50 years non-prorated on materials, and that includes the labor to replace them, plus tear-off and disposal
• 30 years of workmanship coverage backed by CertainTeed, not just by us
• Transferable for 20 years to the next owner

The conditions, in plain terms

Now the conditions, because they’re real and you ought to hear them from me instead of finding out later:

• It requires a full CertainTeed Integrity Roof System. That means the shingles plus CertainTeed underlayment, starter, hip and ridge, and ventilation. CertainTeed shingles with somebody else’s accessories underneath doesn’t qualify. CertainTeed also wants the metal flashings replaced rather than reused, so step flashing, sidewall, chimney, and any skylights. That’s a specification decision made before the job starts, so it has to be in your estimate, and it does cost more than a basic tear-off and re-shingle. Some of that four thousand dollar spread between your two bids is exactly this, which is worth knowing before you assume the cheaper bid is the same roof.
• The durations above are for single-family detached homes. Other structure types cap lower.
• Not every shingle line reaches 50 years. CertainTeed’s XT25 caps at 25 years even at the 5-Star tier, so make sure you know which shingle is written on your estimate.
• It has to be registered with CertainTeed after the install, and there’s a filing window. An unregistered roof is a roof with the standard warranty, no matter what anybody intended. We file it and hand you the confirmation, and I’d tell you to put it with your closing papers rather than a kitchen drawer.
• Make sure you see the current SureStart PLUS document at the time of your job. CertainTeed has changed these terms before, and the version that governs your roof is the one in force the day it gets registered, not the one on a web page.

When the premium system is not the right buy

Now the part that costs us work sometimes. The premium system isn’t always the right buy. If you’re listing the house next spring, or it’s a rental, or you know you’re moving in three or four years, you’re paying up front for coverage that mostly benefits somebody else. Lifetime never applied to a rental to begin with. In those situations I’d rather quote you a solid basic replacement and tell you plainly what warranty comes with it. If your job doesn’t qualify for 5-Star, ask us directly what coverage does apply and get the term in writing before you sign, same as you would with anybody else. Our roof replacement page covers how the whole process runs either way.

One more honest note. Manufacturer coverage is stronger than contractor coverage, but it isn’t a magic word. Manufacturers do deny claims, usually on a ventilation or installation exclusion, and a claim takes time to work through. Which is a decent argument for having it installed right and ventilated right the first time.

Does It Follow the House When You Sell?

Twenty years of transferability is documented on the 5-Star tier, and that’s worth real money when you list the home. But I want to be careful with the word follow, because it makes it sound automatic and it isn’t.

A transfer is something somebody has to actually do, and there’s a deadline attached to it after the sale closes. Miss that window and the coverage doesn’t move. So if you’re buying a house with a newer roof, don’t take the seller’s word for it. Ask for the registration paperwork, find out what tier it was registered at, and find out what the transfer process and the deadline are. If you’re selling, get that paperwork together before closing. It’s a real asset and it’s easy to leave sitting on the table.

Metal Roofs Are a Different Conversation

We get asked about metal warranties a fair amount, especially out around the ag buildings, and this one is more Nick’s territory than mine, so I’d loop him in before you make a decision on it. The short version he gives is that on a standard exposed-fastener or agricultural panel roof, “a typical metal roof warranty is a 40-year paint warranty.” It’s covering the finish rather than promising the roof stays dry, which is not what most people assume they’re buying.

He also points out that on those panels the leaks usually don’t start with the metal at all. It’s the rubber grommets on the exposed screws drying out and letting water in around the fasteners, well before the panel itself is done. Engineered standing-seam systems are a different category and the coverage works differently. Either way, ask specifically what the warranty covers, because finish and watertightness are two different promises. Our metal roof repair page gets into those failure points, and it’s the same conversation whether you’re in Canton, Macomb, or Peoria.

Commercial Roofs Work Differently

I stay on the residential and steep slope side, so this one belongs to Nick. Here’s how he describes what happens on the commercial systems before any warranty gets issued:

Every commercial roof we install, they send out a tech rep to inspect that roof before they issue the warranty. Once they do the inspection, they issue the warranty.

That’s the manufacturer’s own rep, not us, grading the work before they will cover it. If you own a commercial building, that one is a conversation for Nick and our commercial roofing team.

What Actually Voids a Roofing Warranty

Nobody enjoys this part of the conversation, but it’s the useful part. A warranty that exists on paper and doesn’t hold up in practice is worse than no warranty, because you quit worrying about it.

The ones we run into:

• Inadequate ventilation. This is the big one and it’s genuinely common. Trapped heat and moisture cook shingles from underneath, and most manufacturers exclude damage caused by poor ventilation. Ventilation is also part of that Integrity System requirement, so it cuts both ways.
• Roofing over an existing layer. A roof-over is cheaper up front and it can disqualify you from some coverage, including certain wind upgrades.
• Somebody else working on the roof. A satellite installer or a handyman putting fasteners through your field shingles gives the manufacturer grounds to exclude damage caused by that work. Generally, have whoever installed the roof do the repair.
• Never registering it. The most common one of all, and the most avoidable.

Five Questions to Ask Before You Sign

You don’t need to become an expert on any of this. You need five answers, in writing, from anybody bidding your roof. Including us.

• How many years are non-prorated, and does labor come with them? One number, not the headline number.
• Who backs the workmanship coverage, you or the manufacturer? And for how long.
• What credential tier are you registering this at, and does my estimate include the full accessory system that tier requires?
• Who files the registration, and when do I get a copy? Make sure that paperwork ends up in your hands.
• What’s your Illinois roofing license number? Illinois licenses roofing contractors at the state level and requires the number in advertising, so it’s a fair question and an easy one to verify. Ours is 104.007039.

A contractor who’s in it for the long run will answer all five without getting defensive. If the answers get vague, that tells you something too. There’s more on this in our write-up of the red flags worth watching for.

A warranty is only ever as good as the installation underneath it and the company standing behind it. What’s different about Holthaus is they’ve got me. Just kidding. We’ve been in Canton more than thirty years now, with a second office, by appointment, over in Pekin, and in a town this size you see the people you worked for at the grocery store. That keeps a person honest better than any piece of paper does. Get both layers in writing and you won’t be the homeowner who finds out at year twelve.
