IKO Flashing Replacement in Miami, FL

IKO Flashing Replacement: The Miami Owner’s Guide

IKO flashing replacement in Miami typically runs $340-$780 installed for standard residential applications, and we stock the most common IKO profiles on our trucks for same-day completion. Most of our Miami customers call after spotting water stains near valleys, chimneys, or wall joints - places where IKO’s pre-formed flashing was either improperly seated or has finally succumbed to our salt-air climate. If you’re seeing rust streaks, lifted edges, or dampness in the attic after a hard rain, the flashing is the first place we look.

Which IKO Models This Applies To

IKO flashing isn’t one-size-fits-all, and the part you need depends on which shingle system was originally installed. We regularly replace flashing on IKO Cambridge, Dynasty, and Nordic lines across Miami-Dade, plus the older Renaissance and Marathon series still found in Coral Gables and Pinecrest homes from the 1990s and early 2000s.

The critical identifier is the profile height. Cambridge and Marathon use a standard 5-inch exposure with matching 8-inch step flashing; Dynasty’s thicker laminate profile requires the deeper 10-inch step flashing IKO specifies for proper water channeling. The part number is stamped on the underside of existing pieces if you can safely access an edge - look for the IKO shield logo and a code starting with “FL-” followed by the profile series. For valley flashing, IKO’s woven and closed-cut valley systems use different widths: 24-inch for standard pitches under 6/12, 30-inch for steeper Miami roofs common in Coconut Grove and the Beach.

We carry both OEM IKO flashing and a Miami-tested aftermarket equivalent from Quality Edge that meets the same 26-gauge G90 galvanized spec. For coastal properties within three miles of the bay, we typically recommend the OEM - the factory coating holds up better against salt corrosion over a 15-year span. Inland, the aftermarket saves roughly $80-$120 per job with equivalent performance.

We’re an independent service provider - not affiliated with IKO - but we’re authorized to install their full product line and keep current on their spec changes.

Signs Your IKO Flashing Replacement Is Failing

• Rust streaks running down fascia or soffit. Miami’s salt air accelerates galvanic corrosion at cut edges and fastener holes. Once rust appears, the flashing’s protective layer is compromised and water is already migrating behind it.
• Lifting or curling at the edges. IKO flashing is designed to lie flat under shingle courses. Heat cycling in Miami - 95-degree days followed by torrential cooling rains - causes expansion and contraction that pops fasteners. Lifted edges channel water directly underneath.
• Water stains on interior ceilings near valleys or walls. This usually means the step flashing at a wall-roof intersection has separated or the valley pan has cracked at the crease. In Miami’s flat-roof additions common in Little Havana and Allapattah, this is often the first visible symptom.
• Granule accumulation in gutters below flashing joints. When flashing fails, water backflows under shingle tabs and washes granules into the gutter. If you’re cleaning IKO granules from gutters repeatedly, the flashing above is the likely culprit.
• Soft or discolored decking visible from the attic. By the time you see this, the flashing has been leaking long enough to damage the substrate. We find this most often in Miami homes with original IKO installations from the 2004-2006 building boom, where fastener spacing was sometimes rushed.

Replacement Cost & What’s Included

What drives the range: accessibility (steep pitches or tight spaces like Miami’s zero-lot-line homes in Wynwood), whether decking beneath needs spot repair, and whether we’re matching existing IKO color profiles or switching to a compatible aftermarket. Every estimate includes removal of failed material, inspection of underlying substrate, installation of new flashing to IKO spec, and sealant at all penetrations. Our 90-Day Done Right Promise covers the workmanship - if water gets past our flashing, we come back and make it right, no paperwork, no arguing. The number we quote is the number on the invoice.

DIY or Call Us?

Here’s what you can safely check yourself: from the ground or a stable ladder, look for the visual signs above - rust, lifting, stains. Note the IKO shingle line if you can find original paperwork. That’s useful information, and you’re not risking anything.

Here’s where DIY goes wrong: flashing replacement requires removing shingle courses above and around the failure, working on a pitched surface with proper fall protection, and reseating new material so it integrates with the existing water-shedding layers. In Miami’s afternoon thunderstorms, an open roof section can take on gallons of water in minutes. We’ve been called to jobs where a homeowner’s weekend project turned a $400 flashing repair into a $3,000 decking and interior repair. The height work alone is genuinely dangerous - we’ve seen falls from single-story eaves cause serious injury.

We carry IKO-compatible flashing on every truck, and most residential replacements in Miami finish in a single visit. If you’re unsure what you’re looking at, call us at (855) 837-1678. We’ll talk through what you’re seeing, and if it makes sense to send a technician, we’ll give you an upfront price before any work starts.
