Commercial Roofing Warranties: A Brief Guide

Pipes vary in materials from which they are made

Commercial roofing warranties are extremely important if you own a business. While warranties may vary from vendor to vendor and will depend on several factors such as the type of roofing system that is installed, the climate in your area, etc., they are fundamentally similar – it is a binding legal relationship between you and your roofing contractor.

Types of Commercial Roofing Warranties

There are two types of commercial roofing warranties: Manufacturer warranties and contractor, or installer, warranties. If this sounds familiar it is because they are actually no different from the warranty of your residential roofing, the only difference being the type of property the warranty covers.

Manufacturer Warranty:
Manufacturer warranties apply to the materials used for your roofing system. It covers roofing problems that are caused by manufacturing errors or factory defects. There are four basic types of manufacturer warranties namely No Dollar Limit Warranty, Manufacturer’s Material Warranty, Manufacturer’s Labor and Material Warranty, and Manufacturer’s Roof System Warranty.

Contractor Warranties
Contractor warranties, on the other hand, provide coverage for problems caused by installation errors or workmanship issues. Roofing system manufacturers provide detailed instructions on how to properly install their products. They are typically shorter than manufacturer warranties since problems caused by improper installation usually become apparent a few years after your roof is initially installed.

Common Exclusions
Similar to residential roofing warranties, your commercial warranty will have a list of exclusions or conditions where your roof may not be covered such as damage from natural disasters or improper maintenance.

For this reason, it is important that you go over your warranty carefully and make sure you understand all the finer details. If you have any questions or would like to invest in additional coverage then be sure to go over it with your roof repair company.
