At Steadfast Roofing, we bring decades of experience in ensuring metal roofs withstand Florida’s unique climate—from torrential rain to blazing sun, relentless humidity, and intense UV exposure.
🔧 Common Metal Roof Issues Needing Patches
- Corrosion around fasteners and seams: High humidity and salt air can degrade exposed screws and joints, causing rust and water seepage.
- Loose, missing, or damaged fasteners: Vibrations and wind lift panels, leading to gaps and leaks.
- Damaged seam laps and flashing: Sealant breakdown or bent flashing invites water infiltration at edges, roof penetrations, and valleys.
- Surface abrasions or dents: Hail, fallen limbs, or ladder damage can crack coatings, exposing metal to corrosion.
🧼 Inspection Steps for Metal Roof Maintenance
- Semi‑annual inspections in spring and fall: Look for rust spots, blistering, worn sealant, and debris accumulation.
- Fastener torque checks: Re‑tighten with a torque wrench—compress but do not overtighten washers.
- Seam and flashing evaluation: Inspect sealant elasticity; reseal laps and flashing around chimneys, vents, skylights.
- Roof membrane inspection: Even corrosion-resistant panels degrade; inspect visually for coating wear and treat exposed metal promptly.
🛠️ Effective Patch Repair Methods
1. Fastener Replacement & Sealant Application
- Use neoprene-crimp or butyl washers to restore watertight integrity.
- Remove rust, apply a surface‑safe rust inhibitor, and reseal with approved polyurethane or butyl roof sealant.
2. Seam Repair Kits
- Apply elastomeric seam tape over seams after eliminating old sealant.
- Apply a compatible sealant layer on top of the tape, smoothing it to ensure a continuous water block.
3. Patch Panels for Corrosion
- Cut a patch from a matching metal panel, extending 2–3″ beyond the corroded zone.
- Prime bare metal, align the pattern seamlessly, fix with gasketed fasteners, and seal the edges to match the existing finish.
4. Coating Restoration
- For widespread fading or coating loss, clean the surface to bare metal, apply primer, and then apply a reflective acrylic or silicone topcoat—boosting UV resistance and extending the lifespan.
🧴 Recommended Materials & Sealants
- Butyl or polyurethane sealants rated for metal panel movement
- Self-adhered butyl seam tape designed for standing-seam roofing
- Rust-inhibiting metal primers and reflective topcoats
- Washered steel fasteners rated for high-wind applications
📋 Step-by-Step Patch Workflow
- Clean area: remove debris, dust, and rust.
- Prepare the surface: apply a rust inhibitor or primer.
- Position patch or tape: ensure overlap over the damaged area.
- Secure fasteners: ensure durable attachment.
- Seal edges continuously by feathering the sealant outward.
- Clean up: Remove residue and collect old materials.
