The truth about commercial roof warranties is that most are created to limit the manufacturer’s liability rather than offer real protections for you. Many warranties list in great detail what they will not cover instead of what they will and have exclusions that make it ridiculously easy for the manufacturer to invalidate the warranty. Many commercial roofing manufacturers further lack important code approvals for their products and have low standards for granting and maintaining their warranties.
The bottom line: When you’re choosing a commercial roofing company or a certain roofing system, it’s important to dig deeper than just the number of years a warranty covers.
It’s About More Than Just the Number of Years

Exclusions
When you look at the fine print, your warranty may list exclusions that make it very easy for a manufacturer to reject any warranty claims you make. For instance, some roofing warranties stipulate that the presence of animal debris on a roof—something that virtually every roof has within hours of installation due to bird droppings—is grounds for invalidation of the warranty.
Responsibilities
It’s also important to know what your responsibilities are as a consumer. Failure to inspect and maintain a roof in the ways stipulated by your warranty can lead to invalidation of the warranty. Some companies require written notice of a leak within 30 days of the leak being discovered or they may not cover the repairs. Many warranties will further not cover any damage resulting from a leak, such as damage to office equipment or the presence of mold and mildew.
Selecting a product with even a 200-year warranty won’t matter if its language makes it easy for the manufacturer to get out of it and legally refuse your claims.
The bottom line: Know what your warranty covers—and what it doesn’t.
Prorated vs. Non-Prorated Warranties

Diminishing Value
Many roofing products have prorated warranties, which means the warranty coverage lessens over time. This type of warranty is designed to favor the manufacturer. Once your roof is installed and the clock begins to tick, your warranty will cover less and less with each passing year. If you have a 10-year prorated warranty, for instance, and at the eight-year mark your roof needs repairs or replacement, you’ll find that your warranty will only cover 20% of the cost.
A non-prorated warranty, in contrast, requires the issuer to cover a roof for the entire period of the warranty in full. In other words, the manufacturer’s responsibility does not diminish over time.
The bottom line: Make sure your warranty carries its full worth when you are most likely to need it.
Who Do You Think You’re Dealing With?
One of the biggest factors to consider when choosing any roofing product or system is the background of the manufacturer or specific product. Has the manufacturer of your roofing product been around for decades—or has the company only been in business for a couple of years? A well-established manufacturer with a long-time trusted product is obviously the preferred choice.
