When you invest in a new roof for your home or business, you expect it to last for decades. And while most modern roofing systems are designed with durability in mind, unexpected issues can arise—whether due to severe weather, faulty materials, or improper installation. That’s where your roof warranty comes in.
However, many homeowners are surprised to learn that not all roof warranties are created equal. Some offer limited protection, while others come with fine print that can leave you responsible for thousands in repairs. To truly understand the value of your roof warranty, you need to know what it covers—and just as importantly, what it doesn’t.
Let’s break down the key components of a roof warranty, what’s typically included, and common exclusions that every homeowner in Oklahoma should be aware of.
The Two Types of Roof Warranties
Roof warranties generally fall into two main categories:
1. Manufacturer’s Warranty (Material Warranty)
This warranty comes from the manufacturer of your roofing materials (such as shingles, metal panels, or TPO membranes). It covers defects in the materials themselves—in other words, if the product fails before its expected lifespan due to a manufacturing flaw.
Typical coverage includes:
- Premature cracking or granule loss on shingles
- Delamination or splitting of materials
- Defective underlayment or membranes
These warranties often range from 20 years to a “lifetime,” depending on the product line and brand.
However, they do not cover issues caused by improper installation, natural disasters, or poor maintenance.
2. Workmanship Warranty (Installation Warranty)
This warranty is offered by the roofing contractor and covers errors in installation or labor. For example, if your contractor fails to properly seal flashing or align shingles, and that causes a leak, the workmanship warranty would cover the repairs.
The length of this warranty varies by contractor—some offer 1 year, others 5, 10, or even lifetime coverage for workmanship.
What Is Typically Covered
While the exact terms vary between manufacturers and contractors, here’s a look at what is usually covered in a standard roofing warranty package:
✅ Manufacturing Defects
If shingles deteriorate, curl, crack, or lose granules due to a defect in production, the manufacturer will typically cover replacement materials. Labor might be included if it’s a premium warranty.
✅ Blistering or Premature Aging (Material Faults)
High-quality roofing warranties cover premature aging or visible surface defects under normal weather conditions.
✅ Improper Installation (Workmanship)
If the roofing contractor offers a workmanship warranty, issues like faulty flashing, poor sealing, or improper ventilation installation may be covered.
✅ Wind Damage (to a Point)
Some manufacturers offer wind warranties for damage caused by winds up to a specific speed (usually around 110–130 mph). Anything above that, such as tornado-force winds, may fall outside of coverage.
✅ Algae or Mold Protection
Premium shingles often come with limited warranties against algae streaks or biological staining for a set number of years.
What Your Roof Warranty Does Not Cover
Understanding the exclusions is critical—because many homeowners are caught off guard when their claim is denied. Here are the most common exclusions:
❌ Storm Damage (Hail, Tornadoes, Hurricanes)
Most roof warranties do not cover damage from natural disasters. Hail impact, high winds, fallen tree limbs, and tornado damage are typically covered by homeowners insurance, not your roof warranty.
❌ Improper Installation by Unlicensed Contractors
If your roof was installed by someone who isn’t certified by the manufacturer or fails to follow the correct procedures, your material warranty may be voided altogether. Always work with a certified roofer to preserve your coverage.
❌ Neglect or Lack of Maintenance
A common clause in most warranties is that homeowners must perform regular maintenance—like clearing gutters, removing debris, and checking flashing. If you neglect maintenance and that leads to damage, your warranty likely won’t help you.
❌ Alterations and Add-Ons
Modifications to the roof—like satellite dish installations, skylights, or solar panels—can void parts of your warranty unless done professionally and with manufacturer-approved methods.
❌ Improper Ventilation
Many roof systems require proper attic ventilation to perform as intended. If your home has inadequate ventilation and the roof overheats or traps moisture, warranty coverage can be denied.
Common Misunderstandings About Roofing Warranties
“Lifetime” Doesn’t Always Mean Forever
A “lifetime warranty” usually refers to the expected lifespan of the product—not your lifetime. Many of these warranties are prorated after a certain number of years, meaning you’ll receive less compensation the older the roof gets.
Transferability Isn’t Always Automatic
Some warranties are transferable to new homeowners—but only once, and often only within a set timeframe (usually 10 years). Make sure to file the correct paperwork if you’re buying or selling a home with a new roof.
Labor and Disposal Costs May Not Be Included
Many warranties only cover materials, not labor. So if shingles fail due to a defect, you may still be responsible for the cost of tearing off and replacing them unless you purchased an upgraded warranty.
Oklahoma-Specific Considerations
In a state like Oklahoma—where severe storms, tornadoes, and extreme temperature swings are the norm—homeowners should be particularly cautious.
Why It Matters:
- Roofs in Oklahoma face higher wind stress and hail impact than in most states.
- Damage from frequent storms may fall under insurance but not under warranties.
- Choosing a contractor who understands local weather patterns and can install storm-resistant materials correctly is essential.
That’s why it’s smart to work with a local, licensed roofer who offers strong workmanship guarantees and uses products backed by upgraded warranties, including storm damage resistance.
How to Protect Your Warranty
To ensure your warranty remains intact:
- Keep Records: Save your original contract, material purchase info, and warranty documents.
- Get Annual Inspections: Schedule routine professional roof inspections to catch small problems before they void your warranty.
- Follow Maintenance Guidelines: Clean your gutters, trim back trees, and monitor attic ventilation.
- Avoid Unauthorized Work: Only allow certified professionals to work on your roof, especially for repairs or add-ons.
