About roofing warranties

Current state-of-the-art low-slope roofing systems are the result of a century of research and innovation. The relatively recent introduction of numerous systems utilizing rubbers, plastics, modified asphalts and other synthetic materials caused manufacturers to focus attention upon the warranties they offered and to employ long-term warranties as a marketing tool. The National Roofing Contractors Association (NRCA), in the interest of the roofing consumer, acknowledges the following concerns relative to manufacturers' roofing warranties.

The length of a roofing warranty should not be the primary criterion in the selection of a roofing product or system because the warranty does not necessarily provide assurance of satisfactory roofing performance. The selection of a roofing system for a particular project application should be based upon the product's qualities and suitability for the prospective construction project. A long-term warranty may be of little value to a consumer if the roof does not perform satisfactorily and the owner is plagued by leaks. Conversely, if the roof system is well-designed, well-constructed and well-manufactured, the expense of purchasing a warranty may not be necessary.

Manufacturers who use long-term warranties as a marketing tool have encountered a highly competitive roofing market and have found themselves compelled to meet or exceed warranties of competitive manufacturers. It is suspected that in some cases the length of the warranty was established without appropriate technical research or documentation of in-place field performance.

Increased liability risk associated with long-term warranties has contributed to the recent demise of some manufacturers resulting in unanticipated and costly expenses for extensive roof repairs by roofing consumers. Unfortunately, there are a number of manufacturers who issued long-term warranties and who are no longer operating companies with the capability of honoring their warranty commitments, leaving consumers with an ineffective warranty and a serious roofing problem.

There is a common misconception by roofing consumers that long-term warranties are all-inclusive insurance policies designed to cover virtually any roofing problem, regardless of the cause or circumstance. Roof warranties typically do not warrant that the roof system will not leak or is suitable for the project where it is installed. Even the most comprehensive manufacturer warranties that cover material and workmanship generally provide only that the manufacturer will repair leaks that result from specific causes enumerated in the warranty. A material-only warranty typically provides only that the manufacturer will provide replacement material.

Warranty documents often contain restrictive provisions which significantly limit the warrantor's liability and the consumer's remedies in the event that problems develop. The warranty document may also contain other restrictions and limitations such as a prohibition against assignment or transfer of the warranty, exclusion of damages resulting from a defective roof and monetary limitations.

Long-term warranties are largely reactive rather than pro-active solutions to roof problems. In general, they tend to undermine a prudent owner's initial concern for proper roofing specifications and application, as well as their subsequent primary responsibility for periodic roof maintenance.

The roofing consumer is best served by:

• Manufacturers who focus their sales efforts primarily on the relevant and proven merits of those  products and systems best designed to serve the specific needs of the roofing consumer.
  .
• Manufacturers who base warranties for membranes or systems solely upon an honest and realistic appraisal of their proven service life contingent upon the financial ability and good faith of the issuer to honor those warranties for the duration of the designated warranty term.
  .
• Manufacturers who clearly and conspicuously state in writing all recommended, as well as required, owner maintenance responsibilities during the projected service life of the roof.
  .
• Manufacturers who solicit from the roofing consumer a clear understanding of the consumer's primary responsibility to provide periodic routine maintenance during the service life of the roof membrane.

NRCA believes that the roofing consumer, with the assistance of a roofing professional, should focus his purchase decision primarily on an objective and comparative analysis of proven roofing system options that best serve his specific roofing requirements and not on warranty time frames.

NRCA further advises that the roofing consumer consult the membrane warranty section of the Roofing Materials Guide for a comparative analysis of the specific provisions, remedies, limitations, and exclusions of the warranties of those roofing systems under consideration. All questions should be addressed to the respective roofing manufacturers for specific written clarification.
