The Difference Between Denver Commercial Roofing Warranties and Roof Guarantees


Many people use the terms “warranties” and “guarantees” interchangeably when discussing Denver commercial roofing repairs, but these two terms have very different meanings. Every business or commercial property owner should understand how these two terms differ so they know what type of protection they have if an issue with their roof arises. Here’s what you need to know about commercial roofing warranties and guarantees:

Types of Warranties
There are two common types of warranties that cover commercial roofs. The first is a manufacturer’s material warranty, which is issued by the manufacturer of the roofing materials. This type of warranty typically provides protection from 10-30 years depending on material used. This can lead many commercial property owners to think that they are covered if they ever need roof repair. But unfortunately, that’s not necessarily true. A manufacturer’s material warranty will only cover the product if it is defective. For example, if the membrane on a TPO roofing system shows early signs of failure because it was installed next to window glare, it may be replaced under this material warranty.  However most issues arise due to the installation of the roofing materials, not the manufacturing of them. As a result, many commercial property owners are surprised to learn that their warranty does not cover many types of repairs. What does your roof warranty cover?

The second type of warranty is known as a NDL warranty. A NDL warranty is issued by the manufacturer of the roofing materials. A NDL warranty states that the manufacturer agrees in some respect to cover any repairs caused by defective roofing materials and labor.  In some cases the first two years after completion, the repairs are at the cost of the installer. After the initial 2 years the manufacturer will cover both material and labor for the remaining years of the warranty. If things don’t work out this way when a problem does arise, the manufacturer will be on the hook for the terms of the warranty.

There are a few loopholes that a manufacturer or installer can use to get around the terms of a warranty. Don’t just assume that the manufacturer or installer will do the right thing if a roofing issue arises. To avoid these problems, look for an installer that offers a roofing guarantee to customers along with the manufactuers material warranty. Its always best to get the NDL warranty, but they are usally only offered with a commercial project, and only an Authorized or Certified Installer of the product manufacturer can offer them. 

The Basics of Roof Guarantees
A warranty is filled with terms that exclude certain types of roof repairs and severely limit coverage. Often times a guarantee does not have many of these limitations or exclusions. An installer that offers customers a roofing guarantee is agreeing to cover the costs of any repairs that arise due to the materials, labor, or installation process. This means a roofing guarantee will cover everything from defective roofing materials to a problem that arises due to the improper installation of the roofing materials. For this reason, it’s in your best interests to look for a roofing company that offers customers this type of guarantee.


Finding the Right Roofing Guarantee
Many companies may offer roofing guarantees, but don’t take them at their word. You should always ask for a copy of the roofing guarantee before agreeing to do business with the roofing company. Ask for a copy of the guarantee from each company that you speak with so you can compare them and determine which offers the most coverage. This is one of many factors that you should consider when deciding which local roofing company to hire.

How do you know which company has the best roofing guarantee? There are a few things you should look for when comparing roofing guarantees from different companies. First, look at the time frame of the guarantee. How long will you be covered by the guarantee? If the guarantee only lasts 1 -2 years, then it may not do you any good. You should also pay attention to the dollar cap on repairs. Each guarantee will specify how much the roofing company will cover when a repair is needed. For example, a guarantee may state that the roofing company will pay $1,000 towards any covered repair. This means if the repair costs $1,500, you will be responsible for paying the $500 balance. Look for a roofing company that offers a guarantee with a high dollar cap on the covered repairs.

Next, find out if there is a fee for coverage under the guarantee. Some roofing companies ask customers to pay a one-time or annual fee for coverage under their guarantees. This is something that you will need to know when comparing guarantees from different companies to ensure you choose the best one.

Finally, read the terms of the guarantee to see if it discusses the cost of labor. Some guarantees will state that although the cost of the repair is covered, the cost of labor to make the repair is not covered. This type of guarantee basically asks commercial property owners to pay for a portion of the repairs that the guarantee is supposed to cover. 

Authorized Installers/Roofing Companies
Only accept and take bids from roofing companies that are authorized or certified from a manufacturer.  There are many roofing manufacturers in the market, and although not all are created equal, they do most of the homework and investigations of the roofing companies for you. Most manufacturers will only offer NDL warranties on behalf of the highest, and most qualified roofing companies.
