FAQ: What Warranty Should I Expect with a Commercial Roof?

When you're investing in a commercial roof in Florida—whether in Jacksonville, Miami, Tampa, or anywhere else—you need to understand the warranty options that come with it. Warranties are not just paperwork; they’re a sign of material quality, installer confidence, and long-term protection.

What kind of warranty do commercial roofing systems usually come with?

Most commercial roofing systems offer two main types of warranties:

• Manufacturer Material Warranty:
  Covers defects in the roofing material itself.

  • TPO, PVC, and metal roofs often come with 20- to 30-year warranties.

  • Modified bitumen and EPDM typically offer 10- to 20-year coverage.

  • These warranties vary based on thickness, UV resistance, and membrane type.

• Installer Workmanship Warranty:
  Covers labor and installation quality.

  • Usually lasts 2 to 5 years, depending on the contractor.

  • Some certified installers may offer longer warranties backed by the manufacturer.

What’s usually included in a commercial roof warranty?

It depends on the type of warranty. Here's what to look for:

• Material Warranty Includes:

  • Defects in the roofing membrane

  • Premature cracking, blistering, or separation

  • Manufacturer-approved flashing components

• Workmanship Warranty Includes:

  • Leaks due to improper installation

  • Incorrect fastening or seam welding

  • Faulty flashing or edge metal installation

Always read the warranty carefully to understand exclusions like:

• Storm damage

• Ponding water

• Roof traffic wear

• Unauthorized repairs

Does a longer warranty mean a better roof?

Generally, yes. Longer warranties often reflect:

• Better material performance over time

• Proper installation by certified professionals

• Confidence from both the manufacturer and the roofer

But always verify:

• Is it prorated or full coverage?

• Does it require annual inspections to remain valid?

• Is it transferrable if the building is sold?
