Types of Roofing Warranties Explained
Understanding the different types of roofing warranties is essential before investing in a new roof. A roof warranty protects your investment, but not all warranties are created equal. Here's what Los Angeles homeowners need to know about roofing warranties.
Contractor Roof Warranty (Workmanship)
A workmanship warranty—also called a contractor roof warranty—covers installation quality. If your roof leaks due to improper installation, this warranty covers the repair.
What our 10-year workmanship warranty covers:
- Installation of roofing shingles and materials
- Application of underlayment, ice-water barrier, vents, and drip edge
- Integration of flashing and waterproofing details
- Repair of any workmanship-related condition affecting roof performance
Industry standard: 1 year
We provide: 10 years
Manufacturer Warranties
Manufacturer warranties cover defects in the roofing materials themselves. These are separate from workmanship warranties and typically last much longer.
How long is a roof warranty by material type:
- Asphalt Shingles: 25-50 year limited lifetime warranties
- Clay Tile: 50 year to lifetime limited warranties
- Concrete Tile: Up to 100 year lifetime limited warranties
- Metal Roofing: 30-50 year limited lifetime warranties
See specific manufacturer's warranty for your specific roof system.
Understanding Non-Prorated vs. Prorated Warranty Periods
Non-Prorated Period (Strong Protection)
The non-prorated period is your full coverage window—typically the first 10 years on lifetime shingles. During this time, if there is a manufacturing defect:
- Manufacturer covers 100% of material cost
- May cover reasonable labor costs
- Coverage terms are strongest during this period
Prorated Period (Limited Protection)
After the non-prorated period ends (typically after year 10), coverage becomes prorated and significantly less valuable:
- Manufacturer pays only a declining percentage of material cost
- Labor is usually NOT covered
- Tear-off is usually NOT covered
Example: If a 30-year-rated shingle fails in year 20, you may only receive a small percentage of material cost—not a new roof. This is why quality installation matters: proper installation extends roof life and keeps you in the strong coverage window longer.
What Voids a Roof Warranty?
Many homeowners accidentally void their shingle manufacturer warranty without realizing it. Here are the most common ways roof warranties get voided:
Improper Installation
- Wrong nails or nail placement
- Missing required accessories
- Adding second layer over existing shingles
Poor Attic Ventilation
- Excessive heat buildup
- Blocked soffit or ridge vents
- Inadequate intake/exhaust ratio
Improper Repairs
- Using non-approved accessories
- Mixing different manufacturer components
- DIY repairs without proper materials
Pressure Washing
- Damages shingle granules
- Voids algae resistance coverage
- Can force water under shingles
Unauthorized Alterations
- Solar panels without proper flashing
- Satellite dish mounts
- Skylights installed incorrectly
Failure to Register
- Enhanced warranties require registration
- Usually within 30-60 days of install
- We handle registration for you
Nail and Nailing Requirements to Maintain Warranty
Improper nail placement is the most common warranty denial reason. All major manufacturers have specific requirements that must be followed precisely.
| Manufacturer | Nail Type | Penetration | # of Nails | Placement |
|---|---|---|---|---|
| CertainTeed | Corrosion-resistant (galvanized, stainless, aluminum) | ¾" into deck or fully through | 4 standard / 6 high-wind | Designated nailing zone, straight and flush |
| GAF | Galvanized steel (min 12-ga shank, ~3/8" head) | ¾" into deck or fully through | 4 standard / 6 high-wind | LayerLock nailing zone on Timberline |
| Owens Corning | Corrosion-resistant roofing nails | ¾" into deck or fully through | 4 standard / 6 high-wind | Manufacturer's nailing strip, not above or below |
| Malarkey | Corrosion-resistant (12-ga typical) | ¾" into deck or fully through | 4 standard / 6 high-wind | Nailing zone, flush (not over or under-driven) |
Key Takeaway: All four major manufacturers require corrosion-resistant nails, ¾" deck penetration, 4 nails standard (6 in high wind), and exact placement in the designated nailing zone. High nailing, angled nails, or overdriven nails are the most common warranty issues.
Roof Maintenance Requirements for Warranty Coverage
While asphalt roofs don't require ongoing servicing like tile or metal, manufacturers do expect reasonable care. Neglect that leads to damage can void your warranty coverage.
Do This to Maintain Coverage
- Keep debris off the roof (leaves, branches)
- Keep gutters clean and flowing
- Trim overhanging tree limbs
- Ensure ventilation remains unobstructed
- Address moss/algae with approved methods
Avoid These Actions
- Don't pressure wash shingles
- Don't walk on shingles unnecessarily
- Don't ignore ponding water or drainage issues
- Don't allow debris to dam behind chimneys
- Don't ignore visible damage or wear
Are Roof Warranties Transferable?
If you're selling your home or buying a home with a newer roof, warranty transferability matters. Here's what you need to know:
Our Workmanship Warranty
- Fully transferable to new homeowners
- No transfer fees
- Coverage continues for remaining warranty period
Manufacturer Warranties
- Transfer policies vary by manufacturer
- Some require transfer fees ($50-$250)
- Some limit transferred warranty length
- Registration may be required within timeframe
