Tamko Flashing Replacement in Miami, FL

Tamko Flashing Replacement: The Miami Owner’s Guide

Tamko flashing replacement in Miami typically runs $280-$520 installed for standard residential applications, and we stock the common Tamko profiles on our trucks for same-day repair. We carry both OEM Tamko flashing and quality-matched aftermarket alternatives that meet the same ASTM standards, so you’re not waiting on a warehouse order while water finds its way in. Most homeowners first realize there’s trouble after a hard summer storm, when they spot a water stain spreading across the ceiling or a drip that wasn’t there yesterday.

Which Tamko Models This Applies To

Tamko’s flashing systems aren’t universal across their shingle lines. The MetalWorks StoneCrest Slate and Steel Shingle profiles use a proprietary roll-formed valley and step flashing with a 5-inch exposure leg, while their Heritage and Heritage Vintage laminated shingle lines integrate with standard 4-inch by 5-inch step flashing in galvanized steel or aluminum. If you’re trying to identify what you’ve got, check the underside of an existing piece for the stamped Tamko part number, usually found on the drip edge return. The MetalWorks series prefix will read “MW-” followed by the profile code.

Here’s where Miami owners get tripped up: Tamko switched from a .019-inch to a .024-inch aluminum gauge in their residential flashing after 2016, and the two are not interchangeable without adjusting the shingle lay. If your roof was built in that window, measure the metal thickness with a caliper or call us out to verify. We keep both gauges on the truck, plus the heavier .032-inch stock we prefer for coastal Miami installations where salt air chews through thinner metal in eight to ten years instead of fifteen.

We’re an independent service provider, not affiliated with Tamko. We source OEM when the job calls for exact matching, but we’ve also vetted aftermarket lines from Quality Edge and Boral that perform to the same spec at a lower parts cost. Carlos Espinosa makes the call on a case-by-case basis, usually after he’s had a look at what’s actually up there.

Signs Your Tamko Flashing Replacement Is Failing

• Water stains on interior ceilings or walls below roof intersections. The most common failure point is the step flashing where a roof plane meets a vertical wall. In Miami’s climate, the expansion and contraction from 90-degree days to 70-degree nights works the fasteners loose, and once the seal breaks, capillary action draws water behind the flashing.
• Rust streaks bleeding down exterior walls from roof-wall joints. This means moisture is trapped behind the flashing and carrying oxidation out with it. On Tamko’s pre-2016 galvanized steel stock, we see this start around year seven in coastal neighborhoods like Coral Gables and Coconut Grove, sooner if the original installer skimped on primer.
• Lifted or buckled shingles along valleys or chimneys. When flashing pulls away from the deck, shingles lose their anchor and start to cup. The wind uplift from a typical July afternoon thunderstorm will finish the job if it’s not addressed.
• Visible gaps or daylight where flashing meets a dormer or vent stack. Tamko’s rubber collar flashing on pipe penetrations hardens in UV faster than the metal components. We’ve replaced collars that cracked clean through in four years on south-facing slopes in Miami.
• Granule accumulation in gutters below valley flashing. This signals that the valley’s centerline has shifted or the flashing edge is protruding, abrading the shingle surface every time it flexes. It’s an early warning most homeowners miss until the leak starts.

Replacement Cost & What’s Included

What drives the range: height of the roof, how many layers we’re working through, and whether the surrounding shingles can be salvaged or need replacement too. Our quote includes removal of the failed flashing, deck inspection for rot, installation of new Tamko-compatible material, and reintegration with existing shingles. Every flashing job carries our 90-Day Done Right Promise. If water finds a path we missed, we come back and make it right, no paperwork, no argument. The number we quote is the number on the invoice.

DIY or Call Us?

There’s a short list of things a careful homeowner can check safely from a ladder: confirming the stain location matches a visible penetration, looking for obvious shingle displacement, and clearing debris that might be damming water against the flashing. Do not climb onto the roof itself. Miami’s tile and shingle roofs are steep, and the morning dew or afternoon rain squall turns them slick without warning.

Where DIY goes wrong is in the details that aren’t visible from below. Proper flashing replacement requires lifting surrounding shingles without tearing them, sealing the nail penetrations correctly, and integrating the new piece with the existing water barrier. Miss one seal point and you’ve traded a small repair for a larger leak in the next storm. We’ve been called in after homeowner attempts that doubled the repair scope. If you’re unsure, call (855) 837-1678. Estimates are free, and most flashing replacements we complete in a single visit.
