A new roof is a significant investment, and a solid warranty can provide peace of mind by protecting you from unexpected repairs and defects.
However, not all roofing warranties are created equal, and many homeowners don’t realize what is actually covered until it’s too late.
At Roofers Worcester, we help homeowners navigate roofing warranties to ensure they get the best protection for their investment. In this guide, I’ll break down the different types of roofing warranties, what they cover, and what they don’t.
Types of Roofing Warranties
1. Manufacturer’s Warranty (Material Warranty)
What It Covers:
✅ Defects in roofing materials (e.g., faulty shingles, premature cracking, or curling).
✅ Coverage typically lasts 20-50 years, depending on the material and brand.
What It Doesn’t Cover:
❌ Improper installation or poor workmanship.
❌ Damage caused by extreme weather, falling debris, or lack of maintenance.
✔ Example: If your shingles start deteriorating well before their expected lifespan due to a manufacturing defect, you may be eligible for free replacement materials.
2. Workmanship Warranty (Contractor’s Warranty)
What It Covers:
✅ Installation errors or poor workmanship.
✅ Leaks or damage resulting from faulty installation.
✅ Coverage typically lasts 1-10 years, depending on the contractor.
What It Doesn’t Cover:
❌ Defective materials (that falls under the manufacturer’s warranty).
❌ Damage from storms, improper maintenance, or homeowner alterations.
✔ Example: If your roofer fails to install flashing correctly, causing leaks, the workmanship warranty should cover repairs.
3. Extended Manufacturer’s Warranty
What It Covers:
✅ Both materials and labor for covered defects.
✅ Typically lasts 25-50 years and includes full roof system coverage.
What It Doesn’t Cover:
❌ DIY installations or work by uncertified contractors.
❌ Storm damage or improper maintenance.
✔ Example: If you have an extended GAF or CertainTeed warranty, both materials and installation labor may be covered for a longer period.
4. Prorated vs. Non-Prorated Warranties
- Prorated warranties: Coverage decreases over time, meaning you pay more out-of-pocket for repairs as your roof ages.
- Non-prorated warranties: Provide full coverage for a set period before switching to prorated coverage.
✔ Example: A 50-year prorated warranty may offer full coverage for the first 10 years, then decrease coverage gradually.
What’s Typically Covered?
✅ Material Defects – Premature failure of roofing materials (shingles, tiles, metal panels).
✅ Manufacturing Defects – Poorly made products that don’t perform as advertised.
✅ Workmanship Issues – Installation errors that lead to leaks, sagging, or structural issues (if covered by a contractor’s warranty).
✅ Blow-Off Protection – Some warranties cover shingles blowing off in moderate winds.
✔ Tip: Always check the wind resistance rating of your shingles to see if blow-offs are covered.
What’s NOT Covered?
❌ Storm or Weather Damage – Wind, hail, and heavy rain are usually excluded (home insurance may cover this instead).
❌ Lack of Maintenance – If you neglect inspections and cleaning, your warranty may be voided.
❌ Improper Installation by an Unlicensed Roofer – If a contractor isn’t certified by the manufacturer, your warranty may be void.
❌ Algae and Moss Growth – Some warranties exclude algae stains, though certain brands offer algae-resistant shingles.
❌ Interior Damage – Water damage to ceilings, walls, and belongings is not covered by most roofing warranties.
✔ Tip: Read the fine print—some warranties require proof of regular maintenance to remain valid.
How to Keep Your Roofing Warranty Valid
✔ Hire a Certified Roofer – Ensure your contractor is licensed and manufacturer-certified.
✔ Follow Maintenance Guidelines – Schedule annual roof inspections and clean gutters regularly.
✔ Register Your Warranty – Some manufacturers require you to register your warranty after installation.
✔ Don’t Alter Your Roof – Adding solar panels, skylights, or satellite dishes without approval may void your warranty.
✔ Keep All Paperwork – Save your warranty documents, receipts, and inspection reports.
✔ Tip: Check if your roofing contractor offers a warranty transfer option if you plan to sell your home.
