Earlier this year, asphalt shingle manufacturers significantly increased the duration of warranty coverage for the most popular segment of the asphalt shingle roofing product market: laminated asphalt shingle products. Asphalt shingle manufacturers have replaced their "30-year laminated shingles" designation (based on product warranty length) with a "lifetime shingles" designation in their updated asphalt shingle product warranties.
GAF Materials Corp., Wayne, N.J., released an announcement Jan. 10 stating all GAF Materials laminated shingles installed after Jan. 1 automatically are covered by a lifetime limited warranty. Similar announcements from other asphalt shingle manufacturers followed, with a few exceptions.
However, when a company markets a warranty as a "lifetime" warranty, it does not necessarily guarantee satisfactory performance. It is important to consider why companies decide to extend warranties and whether a product's performance history is adequate.
