A roof warranty in Texas covers far less than most homeowners assume — and the gaps between what’s covered and what isn’t can cost you thousands of dollars when something goes wrong. Understanding the difference between manufacturer warranties and workmanship warranties, what voids each one, and what to look for when hiring a contractor is essential knowledge for any Texas homeowner investing in a new roof.
The Two Types of Roof Warranties
Every roofing installation involves two separate warranties that cover completely different things.
A manufacturer warranty covers defects in the roofing material itself. If shingles crack, blister, or fail prematurely due to a manufacturing defect, the manufacturer warranty covers replacement of the defective material. It does not cover installation errors, storm damage, or normal wear and tear.
A workmanship warranty covers the contractor’s installation. If your roof leaks because of improper flashing, incorrect nailing patterns, or other installation errors, the workmanship warranty covers the repairs. This warranty is only as good as the contractor who issued it — a storm chaser who leaves town after completing your job isn’t going to honor a workmanship warranty two years later.
How Long Do Roof Warranties Last in Texas?
Manufacturer warranties on standard architectural shingles typically run 25 to 30 years for the shingle itself, with coverage that decreases over time. Most manufacturer warranties are prorated — meaning they cover 100% of defective material costs in the early years but a decreasing percentage as the roof ages.
Premium shingles from manufacturers like CertainTeed and Malarkey offer enhanced warranty programs that provide non-prorated coverage and longer terms for contractors who are certified installers. Silver Ridge Roofing is CertainTeed certified, which means our customers qualify for CertainTeed’s strongest warranty programs.
Workmanship warranties vary significantly by contractor. Reputable contractors typically offer 5 to 10 year workmanship warranties. Storm chasers and low-quality operators often offer little to no meaningful workmanship coverage — or they won’t be in business to honor it when problems arise.
What Voids a Roof Warranty in Texas
This is where most Texas homeowners get surprised. Several common situations can void your manufacturer warranty entirely:
Installation by a non-certified contractor. Most premium manufacturer warranties require installation by a certified contractor. If your roof was installed by an uncertified contractor, your manufacturer warranty may be void from day one even if the shingles themselves are defect-free.
Improper ventilation. Roofing manufacturers require adequate attic ventilation as a condition of their warranty. Insufficient ventilation causes heat and moisture buildup that accelerates shingle degradation — and manufacturers won’t cover premature failure caused by ventilation problems.
Walking on the roof incorrectly. Repeated foot traffic on shingles that aren’t designed for it can damage the surface and void warranty coverage on affected areas.
Layering new shingles over old ones. Installing new shingles over an existing layer — called a re-roof or overlay — typically voids or significantly limits manufacturer warranty coverage.
Repairs made by uncertified contractors. If a non-certified contractor repairs your roof after a storm or leak, many manufacturer warranties are voided for the affected areas.
Does Homeowner’s Insurance Work with Your Warranty?
Your homeowner’s insurance and your roof warranty cover different things and work independently. Insurance covers storm damage — hail, wind, and other sudden events. Your warranty covers manufacturing defects and installation errors. They don’t overlap, but they also don’t conflict.
Where it gets complicated is when storm damage accelerates a pre-existing warranty issue. For example, if your roof had inadequate ventilation that was slowly degrading your shingles, and a hail storm then damaged those already-weakened shingles, sorting out what’s covered by insurance versus what’s a warranty issue requires careful documentation.
Silver Ridge Roofing documents every installation thoroughly — ventilation measurements, material certifications, nailing patterns, and installation photos — so that warranty and insurance claims are fully supported if issues arise later.
What to Ask Your Contractor Before Signing
Before any roofing contractor starts work on your Texas home, ask these three questions:
What manufacturer are you installing and what warranty program does that qualify me for? A certified contractor will know the answer immediately and can provide documentation.
What workmanship warranty do you offer and is it in writing? Get the workmanship warranty in the contract, not just a verbal promise.
Are you a certified installer for this manufacturer? Ask them to prove it — certification can be verified directly on the manufacturer’s website.
