Commercial roofing warranties vary between manufacturers and roofing types, but they have enough similarities that you can make informed decisions when choosing what’s best for the commercial property that you own or manage. As one of the leading roofing and gutter companies in Southern Maryland, ExteriorPros shares a quick guide to the basics of commercial roofing warranties.
Types of Warranties
Like most types of warranties for building-related products and services, commercial roofing warranties have two parts: manufacturer and installation warranty.
Manufacturer warranty, also known as factory warranty, provides coverage for roofing issues caused by factory defects. There are four types of manufacturer warranties for commercial roofs:
1. No dollar limit (NDL) warranty — Manufacturers with NDLs offer material cost coverage for defective materials at full value, except for labor costs and other adjacent systems that may be affected, such as work by gutter installers.
2. Manufacturer’s material warranty — Some roofs are built using a combination of materials from different manufacturers, in which case the manufacturer will only provide coverage for warranted materials that they’ve manufactured.
3. Manufacturer’s labor and material warranty — This type of warranty provides coverage for both materials and labor up to a certain dollar limit. The manufacturer may have requirements like the roof has to be installed by a certified installer.
4. Manufacturer’s roof system warranty — Roofers refer to this type of coverage as “membrane only” warranty because it only covers the main roofing material.
It’s important to note that manufacturer warranty coverage is typically prorated. This means the full cost of materials and/or labor will be covered for the first few years, then at a percentage that diminishes for the rest of the roof’s life span.
The installation or contractor warranty covers issues caused by installation errors, which is, more often than not, the cause of early roofing failure. Some roofing manufacturers provide installation warranties through certified contractors. In its absence, a commercial roofing contractor may offer a “workmanship guarantee”.
Warranty exceptions are the conditions that are not covered by the warranty or may void coverage. Conditions that are typically covered by insurance, such as weather-related damage, may not be covered, so keeping your insurance policies up to date is important. Lastly, neglecting maintenance is an exception that can result in a voided warranty coverage.
