The terms and conditions in commercial roofing warranties can vary between manufacturers and roofing types. However, there are certain similarities that can help you make informed decisions when comparing warranties.
The Types of Commercial Roofing Warranties
Like their residential counterparts, there are two types of limited warranties for commercial roofing systems: manufacturer and installation warranties.
Manufacturer warranty is also known as a factory or material warranty. It covers roofing issues caused by factory defects and may include coverage for accessories. Manufacturer warranties are typically prorated. This means coverage will be 100% for the first few years, and then the percentage diminishes over the roof’s lifespan. There are four types of manufacturer warranties:
1. No dollar limit (NDL) warranty – An NDL warranty offers coverage for defective materials at full value. The other associated costs of roof repairs, such as labor or damage to adjacent systems like the gutters, may not be covered.
2. Manufacturer’s material warranty – If the roof is built using a combination of materials from different manufacturers, the roofing manufacturer may only provide coverage for their materials.
3. Manufacturer’s labor and material warranty – This provides coverage for both materials and labor, but only up to a certain dollar limit. The roof may need to be installed by a certified roofing contractor to qualify for coverage.
4. Manufacturer’s roof system warranty – This is also known as the “membrane only” warranty because it only provides coverage for the main roofing material.
Installation warranty is also known as contractor warranty and covers problems caused by installation errors. Coverage is typically offered through the roofing contractor as a “workmanship guarantee”, but some manufacturers include coverage through certified contractors.
Warranty exceptions are conditions that are not covered by the warranty or actions that may result in voided coverage. Roofing problems that are covered by insurance, including weather-related damage, can be considered as exceptions – which is why insurance and warranties go hand-in-hand; one should not be substituted for the other. Conditions that may be considered neglect, such as not keeping up with maintenance or making unauthorized modifications to the roof, may result in voided warranty coverage.
