Metal Roof Repair

Backed-out fasteners where thermal cycling has walked screws out of the deck. Failed neoprene washers under the fastener heads - the number-one Miami metal roof leak source. Seam separation on exposed-fastener panels. Coastal-edge corrosion on aluminum, galvalume, and steel panels near saltwater. Wall flashing, curb flashing, and pipe penetration flashing where sealant has aged out.

For each of these we use correct-specification hardware and sealants - not a generic caulk fix - and document the repair with photos.

Salt air in coastal Miami neighborhoods - Key Biscayne, Coconut Grove, Miami Beach, Aventura, the barrier islands - accelerates fastener and cut-edge corrosion measurably. Metal roofs within a few blocks of open water should be inspected on a shorter cycle than inland roofs.

During a coastal metal roof repair we address the immediate failure and flag any accelerated corrosion we see. If the panels themselves are beginning to corrode at cut edges, we say so - a proactive edge treatment or panel section replacement is often much cheaper than waiting for a full re-roof.

Miami metal roofs come in two families that fail in very different ways. Standing seam metal roofs — with concealed clip fasteners and raised interlocking seams — are the most durable metal system for coastal Miami, and their failures cluster at end conditions: eaves, ridges, valleys, and any place a penetration crosses the seam. Repair on a standing seam roof is precision work that respects the panel movement the system is designed for.

Exposed fastener panel roofs — the 5V, R-panel, and screw-through profiles common on older Miami homes and outbuildings — fail primarily at the fasteners themselves. Washers crack, screws walk out of the deck, and every fastener eventually needs to be re-torqued or replaced. A correct metal roof repair on these systems is a fastener-by-fastener pass, not a spot patch.

Different systems, same principle: fix the connection that failed, verify the surrounding connections, and document what was done.

Metal roof sealant on Miami roofs is a specific class of material — high-solids polyurethane or STPE-based sealants rated for the movement and UV that a metal panel sees over years. Off-the-shelf silicone or generic caulk pulled from a hardware store shelf fails within a season and often leaves a residue that prevents the correct product from adhering later. Using the wrong sealant on a metal roof repair is one of the most common ways a repair fails prematurely in Miami.

For aluminum roof panels near the coast, we also monitor cut edges and any place where an old fastener has been removed and re-driven — those are the corrosion initiation points that turn into panel replacement later. On a coastal maintenance interval — 12 months instead of the inland 24 — we catch those early. It is dramatically cheaper to treat a corroding cut edge than to replace a corroded panel section.

Every metal roof repair leaves the roof with correct-specification hardware, correct sealants, and photo documentation of the work performed.
