Metal Roof Repair in Austin — Screws, Seams, Flashing, and Hail Dents.

We repair shingle, metal, modified bitumen, and some TPO flat roofs — both residential and light commercial. Metal roof repair divides by fastening system. Standing seam and exposed-fastener panels are different metal-roof systems. We also diagnose water coming through the roof so the repair addresses the source rather than just the symptom. This page is about repairing the metal roof you already have: metal roof repair addresses fasteners, seams and flashings on an existing metal roof; a metal roofing service replaces the system when repair no longer holds. Choosing and installing a new metal roof is covered on our metal roofing page.

On exposed-fastener (screw-down) roofs, the dominant failure is the fasteners themselves: thousands of gasketed screws whose neoprene washers UV-degrade, crack, and lose compression as panels expand and contract daily — leaks then follow the screw lines. Because the panel expands and contracts against a fixed screw, the holes gradually elongate while the screws work loose or the washers extrude. Signs include rust halos around screw heads, visibly raised screws, and drips at purlin lines. The durable repair replaces fasteners with oversized screws and new washers across the roof, not dabs of caulk on the leakers, because every washer on the roof is the same age.

On standing seam roofs, the panel field is fastener-free, so leaks concentrate at flashings, penetrations, end laps, and ridge details, and repairs are detail work demanding familiarity with the specific seam profile. Failures concentrate at the details rather than the field: eave and ridge closures, penetration flashings, and seams left un-crimped on mechanical-lock profiles. Repairs demand a specialist, since panels interlock and cannot be swapped like shingles.

Re-fastening — not caulking each screw — is the durable fix. Sealant chemistry matters (butyl and polyurethane products adhere to metal long-term; general-purpose silicone often does not), dissimilar-metal contact corrodes (copper wash over galvanized steel, for instance), and rust at scratches and cut edges is arrested early with rust-inhibiting treatment and touch-up. On Galvalume steel, copper or lead contact, treated lumber, and runoff from dissimilar metals corrode the coating, so repairs must not introduce them. Every Zilker roof repair follows a clear process: inspection and diagnosis; a written proposal with photo documentation; the agreed repairs; a final review of the work. Repairs carry a 2-year workmanship warranty. We document the applicable terms in writing.

The ceiling stain is not the leak. Water enters at a flashing, penetration, or fastener, runs down the underside of the decking or along a rafter, and drops onto the ceiling somewhere downslope — so the stain is the exit, not the entrance. Exposed-fastener panels rely on rubber washers that dry out in the Texas sun; standing seam hides its fasteners and has far fewer of those failure points. Two decoys are worth ruling out: condensation from attic humidity or uninsulated ducts mimics a leak in summer, and wind-driven rain can enter vents and exhaust caps that are watertight in ordinary weather. Finding the entry point first means the repair addresses the source rather than just the symptom.

Roof repair is appropriate for localized damage when the surrounding system is sound. Replacement is warranted when damage is widespread, the roof is near the end of its useful life, or the system can no longer be repaired reliably. A roof inspection determines which is appropriate, and we recommend repair when repair is right. Some things that look wrong are not repair items: oil-canning — visible waviness in flat panel areas — is cosmetic, not a defect requiring repair. Zilker Roofing does not recommend a full roof replacement when a targeted repair is the right solution. The repair-vs-replace decision is driven by the condition of the roof, not by what is most profitable.

Hail can dent or otherwise damage metal roofing; the result depends on the product, thickness, support, and impact. Cosmetic damage affects appearance only, like dents in a metal panel or vent cap that still perform; functional damage shortens the roof's life or compromises how it sheds water. From a safe place, note visible damage and the storm date. Do not climb onto a wet or damaged roof. An active leak, storm-damaged roof, or tree puncture needs prompt attention. Scheduling and temporary stabilization depend on weather, safe access, materials, and crew availability. If hail or wind affects a metal roof, Zilker can document visible roofing conditions and prepare an estimate for roofing work. The property owner decides whether to file a claim; the insurer determines policy coverage and claim handling. The estimate can explain the proposed metal system and scope; it does not determine coverage or negotiate a claim. Contact your insurer promptly about possible damage and applicable deadlines; an inspection appointment should not delay that call. Zilker Roofing is not a licensed public adjuster. We do not file insurance claims on your behalf, negotiate with your insurance carrier, or speak to your insurer without your involvement. We provide documentation and support only. Zilker Roofing does not use Assignment of Benefits contracts. The homeowner remains the policyholder in control of their claim at all times.
