Warranties and Inspections: Manufacturer vs. Contractor

There are two basic types of warranties. Those issues by the manufacturer and those issued by the contractor. Granted, there are many, many warranty options, but warranties are generally issued by one of the two parties above.  Terms and specifications of the warranty are determined by the issuer. That party is also responsible for any warranty claim. LaFerney Commercial Roofing believes that a roof should be required to pass an inspection prior to the warranty being issued, but that is not always mandatory. 

Let’s look at the manufacturer warranties first. In the majority of instances the terms of a manufacturer’s warranty will require an inspection conducted by a representative of the manufacturer. This inspection should include the installation of the insulation, membrane, and flashing. In some instances the manufacturer will allow a sales representative to act as the manufacturer representative and conduct this inspection. This brings potential for a conflict of interest in raising the question of the ability of this sales representative to critique work for a customer with whom a continued relationship and future sales depends on the product performance. Some manufacturers circumvent this possible conflict of interest by providing a technical inspector with no direct sales responsibility to perform the inspections. This promotes a higher level of objectivity in the inspection process. Again, inspections are not required by all manufacturers. 

LaFerney Commercial Roofing ONLY works with manufacturers who provide frequent, rigorous inspections conducted by technical representatives in a non-sales related role. Our superior inspection ratings have earned Elite Contractor ratings from manufacturers. We further require the manufacturer to provide complete support of their warranty. We do this for the protection and peace of mind of our customers. 


Now, let’s talk about contractor warranties. These are written and upheld by the contractor – not the manufacturer. Terms, conditions, issuance, and support of the warranty are all the responsibility of the contractor. The contractor will install the roof and, if inspected, determine the quality of his/her own work. Should any warranty related problems arise, the contractor will be responsible for the repair. With this type of warranty, a contractor can create their own roof installation specification and select the material components to comprise the roof system themselves. Often, the contractor relies on experience rather than industry specific testing. 

LaFerney Commercial Roofing prefers projects to be inspected at regular, scheduled intervals. LaFerney further recommends semi-annual inspections after the completion and for the duration of the roof’s life-cycle. These inspections should occur in early spring to repair any damage from winter, and the second in early fall to prepare the roof for colder weather conditions. Think of your roof as capital equipment in your business. As with any other piece of capital equipment, proper maintenance is strongly encouraged to maximize performance and longevity.
