Replacing a roof is one of the largest single investments you’ll make as a Metairie homeowner, and the warranty that comes with it determines how well that investment is protected over the next 20 to 50 years. Between manufacturer coverage on the shingles themselves and workmanship guarantees from your installer, there’s a lot of fine print that directly affects what happens when something goes wrong. Big Easy Roofers walks Jefferson Parish homeowners through every warranty detail before work begins, so there are no surprises down the road.
A manufacturer’s warranty covers defects in the roofing materials themselves — shingles that curl prematurely, granules that shed faster than they should, or tiles that crack under normal conditions. This warranty comes from the company that made the product, not the contractor who installed it.
Most asphalt shingle manufacturers offer warranties ranging from 25 years to what they market as “lifetime” coverage. That “lifetime” designation has a specific legal meaning that varies by manufacturer — some define it as 50 years, others cap it at the expected useful life of the product. Read the actual warranty document, not just the marketing language on the shingle packaging.
For Metairie homeowners, manufacturer warranties that specifically address wind and algae resistance matter more than they would in other parts of the country. Jefferson Parish sits in a high-wind zone, and the humidity rolling off Lake Pontchartrain creates prime conditions for algae streaking. Many premium shingle lines include algae-resistance warranties of 10 to 15 years and wind warranties rated to 110 or 130 mph — but these enhanced coverages often require specific installation methods to remain valid.
Major manufacturers like GAF, Owens Corning, and CertainTeed all offer tiered warranty programs. The base-level warranty covers only the materials. Higher tiers — which typically require installation by a manufacturer-certified contractor — add coverage for labor costs, provide non-prorated protection for longer periods, and sometimes include a workmanship guarantee backed by the manufacturer rather than just the installer.
The workmanship warranty covers installation errors — improperly driven nails, flashing that wasn’t sealed correctly, underlayment that was installed in the wrong direction, or starter strips that were skipped. This warranty comes from your roofing contractor, and it’s only as reliable as the company standing behind it.
Workmanship warranty periods vary widely in the Metairie market. Some contractors offer as little as one or two years; others provide five, ten, or even 25-year workmanship guarantees. The length of the warranty matters, but so does the contractor’s track record and financial stability. A 25-year workmanship warranty from a company that folds in three years isn’t worth the paper it’s printed on.
Before signing a contract, verify that the contractor is licensed through the Louisiana State Licensing Board for Contractors (LSLBC) and carries both general liability in
