Commercial roof systems often come with warranties that provide assurance and protection for building owners. The types of warranties available for commercial roof systems can vary depending on the manufacturer, roofing material, and specific terms and conditions. Here are some common types of warranties you may come across:
Manufacturer's Warranty: Also known as a material warranty. Most roofing material manufacturers offer warranties that cover their products against manufacturing defects. These warranties typically guarantee that the roofing materials will perform as intended for a specified period. Stated another way, this is the length of time that you can expect the roofing materials to last on top of your building. Manufacturers' warranties can range from 10 to 30 years or more, depending on the product, manufacturer, and roof type.
Workmanship Warranty:
Also known as a labor warranty. This is a warranty that comes directly from the installing contractor. It is the period of time that the contractor will warranty the roof for defects in their workmanship. These often are of shorter time periods of 1-5 years, but sometimes up to 10 years.
System Warranty: System warranties cover both the roofing materials and the installation workmanship. These warranties are typically provided by roofing contractors or roofing system manufacturers. System warranties offer comprehensive coverage and ensure that both the materials and installation meet the manufacturer's specifications. They may have different durations for materials and workmanship, with coverage ranging from 5 to 20 years or longer.
Prorated Warranty: Prorated warranties cover the roofing materials for a specified period but decrease in coverage value over time. Typically, prorated warranties offer full coverage for a specific period, followed by decreasing coverage percentages as the warranty progresses. This means that the building owner may be responsible for a portion of repair or replacement costs as the warranty ages.
It is important to carefully review the terms and conditions of any warranty before making a decision. Consider factors such as the duration of coverage, any exclusions or limitations, and the reputation and financial stability of the manufacturer or roofing contractor offering the warranty. Consulting with roofing professionals can provide valuable insights and help you choose the most suitable warranty for your commercial roof system.
