When you buy a new roof, you are also buying a set of warranties, and they are easy to misunderstand. Most homeowners picture a single guarantee, but a roof actually comes with two very different ones that cover different things. Knowing the difference tells you what is really protected, and it can save you a frustrating surprise years down the road. Here is how roofing warranties work.
The two warranties on every roof
A new roof is covered by a manufacturer warranty and a workmanship warranty. They come from different places and protect against different problems, and a roof is only fully protected when it has both.
The manufacturer warranty covers the materials
The manufacturer warranty comes from the company that made the shingles, and it covers defects in the product itself. If the shingles fail because of a manufacturing flaw, this is the warranty that responds. These warranties often carry long or even lifetime terms, but it is worth reading the fine print, because the coverage frequently steps down over time and may only cover the materials rather than the labor to install replacements.
The workmanship warranty covers the installation
The workmanship warranty comes from the contractor, and it covers how the roof was installed. This is the one that matters most day to day, because the truth of roofing is that most leaks are not caused by defective shingles. They are caused by installation, an improperly flashed chimney, a missed nailing pattern, a valley that was not detailed correctly. A defective shingle is rare. A workmanship issue is what actually drives most callbacks, and only the contractor warranty covers it.
Why the contractor behind it matters
A workmanship warranty is a promise, and a promise is only as good as the company making it. A long warranty from a contractor who may not be around in a few years is worth very little. This is one more reason to choose a local, established roofer with a track record, because they are still here and still accountable when you need them. Storm-chasing crews who disappear after the season leave their warranties disappearing right along with them.
How certification raises the bar
There is a third layer worth knowing about. When a contractor is certified by a shingle manufacturer, that manufacturer will often back enhanced warranties that an uncertified installer simply cannot offer, sometimes covering both materials and labor for a longer term. The certification exists because the manufacturer trusts that crew to install the system correctly, which protects you on both fronts at once.
What to check before you sign
Get the workmanship warranty in writing, with the term and what it covers spelled out.
Read how the manufacturer warranty steps down over time and whether it covers labor.
Ask whether the contractor is manufacturer certified and what enhanced coverage that unlocks.
Find out whether the warranties are transferable if you sell the home, which adds real value.
Confirm the company is local and established enough to honor the promise.
Coverage you can count on
Our shingle systems carry a lifetime workmanship guarantee, and many of these warranties are transferable to the next owner. More important than any document, though, is being a local contractor who stands behind the work and is here when you need us. A warranty should be a promise you can actually collect on.
