More than the shingles you see.
A roof replacement starts with what is underneath. Understand the decking, underlayment, flashing, ventilation, and roofing materials in your written scope before the work begins.
What a Replacement Includes
A roof system combines components such as the roof covering, underlayment, flashing, ventilation, and roof decking. The right materials and work scope depend on roof design, existing conditions, product instructions, and applicable code. The estimate identifies the components proposed for your project. Roof replacements carry a 5-year Zilker workmanship warranty. Manufacturer material-warranty coverage is separate and depends on the selected products, installed system, eligibility requirements, and written terms; ask for the applicable warranty documents.
The Replacement Process
The process begins with an inspection and written estimate that describes the proposed materials, labor, and project scope. Schedule and duration depend on roof size and complexity, weather, access, crew availability, and conditions discovered after tear-off. The estimate or project plan should state the expected schedule. After removal, the crew reviews the exposed deck, completes the agreed work, and reviews the finished project with the customer.
When Storm Damage Leads to Replacement
If a roof inspection shows storm damage severe enough that replacement may be warranted, homeowners insurance may be involved depending on the policy, deductible, carrier review, and documented roof condition. Zilker Roofing inspects and documents the damage and can explain, educationally, what a Summary of Damages or scope of loss means — so you understand your own claim paperwork — and we provide our own detailed, independent roofing estimate. The claim remains yours: you and your insurer file, review, and settle it, and you decide whether to file at all. Zilker Roofing does not use Assignment of Benefits contracts and is not a licensed public adjuster, so we do not file claims on your behalf or negotiate with your insurance carrier.
Full Tear-Off. No Shortcuts.
No — Zilker Roofing does not install new shingles over an existing roof system. A full tear-off allows us to inspect the decking, correct hidden issues, and install the new roof system properly.
What you can expect
Clear from the start.
5-Year Workmanship Warranty
Roof replacements carry a 5-year Zilker workmanship warranty and repairs a 2-year workmanship warranty. Manufacturer material coverage is separate; its duration, exclusions and any enhanced protection depend on the selected product and written warranty terms.

Manufacturer material coverage and contractor workmanship coverage address different risks. Compare the written terms for the selected roof, including any optional enhanced protection.
