Understanding Roof Warranties in Los Angeles
Roof warranties in LA come in two types: manufacturer and workmanship. Learn what each covers, what voids them, and what to look for before you sign.
A new roof is one of the biggest investments you will make in your home. The warranty that comes with it is supposed to protect that investment. But not all warranties are the same, and the fine print matters more than most homeowners realize.
Here is what you need to know about roof warranties in Los Angeles.
Two Types of Roof Warranties
Every new roof replacement should come with two separate warranties.
Manufacturer warranty. This covers defects in the roofing material itself. If your shingles crack, delaminate, or fail prematurely due to a manufacturing flaw, the manufacturer covers the cost of replacement materials. Most major manufacturers offer 25 to 50 year material warranties on architectural shingles and longer on tile and metal.
Workmanship warranty. This covers the installation. If a leak develops because flashing was installed incorrectly or underlayment was not lapped properly, the contractor’s workmanship warranty covers the repair. These warranties vary widely. Some contractors offer 2 years. Good ones offer 10 years or more.
You need both. A defective shingle is the manufacturer’s problem. A good shingle installed wrong is the contractor’s problem.
What Manufacturer Warranties Actually Cover
Manufacturer warranties sound generous on paper. A “lifetime” or “50-year” warranty gets attention. But read the details.
Standard warranties cover replacement materials only. They do not cover labor to remove the failed material and install the new. Labor is typically 60 to 70 percent of the total job cost.
Enhanced warranties cover both materials and labor. These are only available when a certified contractor installs the manufacturer’s full roofing system, including their underlayment, starter strips, and ventilation products.
Prorated vs non-prorated. Some warranties are prorated after a certain number of years. A 30-year warranty might provide full coverage for the first 10 years, then reduce the payout by a percentage each year. By year 25, coverage might be only 15 to 20 percent of replacement cost.
What Voids a Roof Warranty
Both manufacturer and workmanship warranties have conditions that can void coverage.
Improper ventilation. Almost every shingle manufacturer requires adequate attic ventilation as a warranty condition. If your attic does not meet their specs and shingles fail prematurely, they can deny the claim. This is one of the most common warranty denials.
Unauthorized modifications. If someone installs solar panels or a skylight and penetrates the roof membrane without following manufacturer guidelines, the warranty on the affected area may be voided.
Pressure washing. Pressure washing a shingle roof strips granules off the surface. Manufacturers consider this homeowner-caused damage. Use a low-pressure chemical treatment for algae or moss instead.
Failure to register. Many warranties require registration within 30 to 90 days of installation. Without registration, you may only have basic coverage instead of the enhanced warranty you were promised. Ask for proof of registration.
What to Look for Before Signing
When getting quotes for a roof replacement or major roof repair, ask these questions:
- What is the manufacturer warranty length and is it prorated?
- Does it cover materials only or materials and labor?
- What is the workmanship warranty length?
- Is the workmanship warranty transferable if you sell the house?
- What ventilation requirements keep the warranty valid?
- Will the contractor handle warranty registration?
Get the answers in writing. Verbal promises do not hold up when you have water coming through your ceiling three years from now.
Transferable Warranties and Home Sales
If you plan to sell your home within the warranty period, transferability matters. Most manufacturer warranties are transferable, but some require a transfer fee ($50 to $200) and must be initiated within a set timeframe after the sale.
A transferable warranty adds real value at resale. Keep all warranty paperwork and registration confirmations in a file you can hand to the buyer at closing.
Frequently Asked Questions
How long is a typical roof warranty in Los Angeles?
Manufacturer material warranties range from 25 to 50 years for shingles and up to lifetime for tile and metal. Workmanship warranties from reputable LA contractors range from 5 to 25 years.
Does a roof warranty cover storm damage?
No. Warranties cover defects in materials or installation. Storm damage is covered by your homeowner’s insurance, not the roof warranty.
Can I void my warranty by walking on the roof?
Walking on an asphalt shingle roof occasionally will not void your warranty. But repeated foot traffic or walking on tile can crack the surface. Have a professional handle any roof work.
What happens if my roofing contractor goes out of business?
The workmanship warranty becomes unenforceable. The manufacturer warranty remains valid since it comes from the material manufacturer, not the installer. This is one reason to choose an established local contractor.
Protect Your Investment
A good warranty protects you from defective materials and sloppy installation. A bad warranty looks good on paper but falls apart when you need it. Read the terms, ask questions, and choose a contractor who offers real workmanship coverage.
