What You’ll Learn in This Guide

Questions to ask your contractor before signing a roofing contract
Why Do Roofing Warranties Matter for Commercial Buildings?
A commercial roofing warranty protects your investment by outlining what’s covered and for how long. Roofing systems shield your business from rain, UV damage, hail, and temperature extremes. Without proper coverage, repairs can become expensive and disruptive.
In Texas, where hailstorms, heavy rain, and scorching heat are common, a solid warranty ensures your roof lasts as long as promised. Ignoring warranty details can lead to unexpected costs, voided coverage, and compromised building protection.
What Are the Different Types of Commercial Roofing Warranties?
Understanding the types of commercial roofing warranties helps you make smarter decisions about installation and maintenance.
What Manufacturer Material Warranties Typically Include
Manufacturer warranties cover defects in roofing materials like TPO, PVC, EPDM, or metal. This usually includes:
Premature cracking or blistering
Material degradation beyond normal wear
Manufacturer-specific repairs or replacements
In Texas, where sun and heat can accelerate material aging, a manufacturer’s warranty ensures that defective materials are replaced without additional cost.
How Contractor Workmanship Warranties Work
Workmanship warranties are issued by the roofing contractor to cover installation errors. This means if improper installation causes leaks, water intrusion, or structural issues, the contractor is responsible for repairs.
A local Texas roofing company may offer 1–10 years of workmanship coverage, giving building owners peace of mind after installation.
What Full System Warranties Cover Long-Term
Full system warranties combine manufacturer and contractor coverage, ensuring that both material defects and installation errors are protected. These comprehensive warranties are ideal for business owners looking for long-term protection against unexpected roof issues.
What Common Issues Void a Commercial Roof Warranty?
Several actions can void a warranty, leaving you financially responsible for repairs:
Improper maintenance or delayed inspections
Unauthorized modifications or repairs
Walking on the roof without precautions
Ignoring manufacturer installation guidelines
Understanding these pitfalls helps Texas owners maintain compliance and protect their warranty coverage.
How Long Do Roofing Warranties Last by Roof Type?
Warranty durations vary depending on roofing materials and type:
TPO Roofing: Manufacturer warranty 10–20 years, workmanship 1–10 years
EPDM Roofing: Material warranty 15–20 years, workmanship 5–10 years
Built-Up Roofs (BUR): Material 15–30 years, workmanship 5–10 years
Metal Roofing: Material 20–40 years, workmanship 5–15 years
Knowing your roof type and typical coverage period helps set realistic expectations.
What Questions Should You Ask Before Signing a Roofing Contract?
Before committing to a commercial roofing project, ask your contractor:
What type of warranty is included, and who backs it?
Does the warranty cover full system replacement or just materials?
Are there exclusions for weather events or maintenance lapses?
What is the process for filing a claim if an issue arises?
How long does coverage last for both workmanship and materials?
Asking these questions ensures transparency and prevents unexpected costs.

Common Challenges with Commercial Roofing Warranties
1) Keeping Up With Required Maintenance If inspections or maintenance are skipped or poorly documented, your warranty can be voided without you realizing it.
2) Unauthorized Modifications or Repairs Adding equipment like HVAC units or doing DIY repairs without approval often eliminates coverage.
3) Misunderstanding What Is Covered Many owners assume they’re covered for all damage — but severe weather and other exclusions are common.
4) Warranty Term Confusion Warranties vary widely by materials and provider, which can make it hard to know what’s truly protected.Â
