CertainTeed Flashing Replacement Nationwide

CertainTeed Flashing Replacement: The Orlando Owner’s Guide

We stock and install CertainTeed-compatible flashing replacement throughout Orlando, with most repairs running $275 – $650 installed depending on the flashing type, roof pitch, and how much of the surrounding shingle needs to be pulled back. A straightforward step flashing replacement on a single-story Orlando home usually lands around $325 – $450, and yes, we can typically get it done the same day once we see the job. Most homeowners discover the problem the hard way: a ceiling stain after an afternoon thunderstorm, or a water ring creeping across the garage drywall. By the time you see it inside, the flashing has usually been failing for months.

Flashing is the metal that keeps water from finding its way through the joints in your roof, and in Orlando’s humidity and afternoon downpour cycles, it works harder than almost any component up there. We’re Tilehurst Roofing Orlando, a Kingswell family roofing company, and we replace flashing on CertainTeed systems every week. We’re an independent service provider, not affiliated with CertainTeed, but we know their products well enough to match the right flashing to the right shingle line without guesswork.

Which CertainTeed Models This Applies To

CertainTeed flashing compatibility depends less on the shingle model and more on the flashing type and the roof’s geometry, but there are a few things worth knowing. If your home has CertainTeed Landmark, Landmark Pro, or Presidential shingles, the flashing itself is almost always a standard galvanized steel or aluminum profile, not a CertainTeed-branded part. The shingle manufacturer matters for color matching and warranty paperwork, but the flashing is selected by the roofer based on the roof’s pitch, the siding or stucco interface, and the chimney or wall condition.

Where CertainTeed branding actually shows up is in their accessory line: CertainTeed makes branded ridge vents, starter strips, and underlayment, but their flashing products are typically sold through roofing supply houses as code-compliant metal profiles. The gotcha we see in Orlando: many older CertainTeed roofs from the 2000s and early 2010s were flashed with thin, 26-gauge galvanized steel that corrodes faster in Florida’s humidity than what we’d install today. If your roof is over 12 years old and you’re seeing rust streaks near the valleys or wall joints, the flashing was likely undersized for our climate. We spec minimum 24-gauge galvanized or pre-finished aluminum on every replacement we do, which holds up significantly longer against Orlando’s wet-season exposure.

Signs Your CertainTeed Flashing Replacement Is Failing

• Water staining on ceilings or upper wall corners after rain. This is the most common first sign in Orlando, and it usually points to step flashing behind a wall or chimney flashing that has pulled away from the mortar. The leak often tracks several feet from the actual breach, so the stain isn’t always directly under the problem.
• Rust streaks or visible corrosion on exposed flashing. If you can see orange-brown streaking running down from a valley or wall joint, the galvanized coating is gone and the steel underneath is thinning. In Orlando’s humidity, this progresses faster than most homeowners expect.
• Lifted or curled shingle edges near walls and chimneys. When flashing moves or pulls loose, the shingles around it lose their anchor point. You’ll often see the shingle edges lifting right where the flashing should be holding them flat.
• Granules accumulating in gutters directly below wall or valley junctions. Shingle wear accelerates wherever flashing has failed, because water pools and runs in concentrated channels. If one gutter section fills with granules faster than the others, look uphill from it.
• Daylight visible in the attic around chimneys or skylights. On a bright afternoon, go into the attic and look toward any roof penetration. If you can see light where there shouldn’t be light, water is getting through the same gap. This is a straightforward check that costs you nothing.

Replacement Cost & What’s Included

Here’s what we quote for CertainTeed flashing replacement in Orlando, and what drives the number:

• Step flashing replacement (wall-to-roof joint): $275 – $425 installed. This is the most common flashing repair on Orlando homes. We remove the first course of shingles, replace the step flashing pieces, re-secure the shingles, and seal everything with a UV-stable roofing sealant.
• Chimney flashing replacement: $450 – $650 installed. The range depends on chimney size, whether we need to cut a reglet (the groove in the mortar that holds the counter-flashing), and whether the existing mortar needs repointing before we can seat the new metal.
• Valley flashing repair or replacement: $300 – $550 installed. This requires lifting shingles on both sides of the valley, so the shingle condition and roof pitch affect the final number.
• Pipe boot or vent flashing replacement: $175 – $275 installed. Small job, big payoff. Orlando’s UV exposure rots the rubber collar on pipe boots faster than most manufacturers expect.

Every quote is a written, line-item price before we touch the roof. That’s The Kingswell Way and it’s not negotiable or optional at Tilehurst Roofing Orlando. The price we hand you is the price you pay, parts and labor included. If the repair fails inside the guarantee period, we come back and fix it at no charge under our 365-Day Done Right Promise. That’s in writing too, delivered before the crew leaves, not mailed later.

DIY or Call Us?

You can safely check a few things yourself: look for visible rust, lift a shingle edge near a wall to see if the step flashing underneath is still flat against the wall, and check the attic for daylight around penetrations. Those checks help you understand the problem before you call anyone.

What we don’t recommend is replacing flashing yourself on a pitched roof. The work requires lifting and re-seating shingles without cracking them, cutting metal to fit the specific wall joint, and sealing everything in the right sequence so water sheds away from the joint instead of behind it. One overlapping mistake and you’ve created a leak that’s worse than the one you fixed. It’s also genuinely dangerous up there: Orlando roofs get slick after rain, and working at height without proper harnesses and roof brackets is how people get hurt. If you’ve found the problem and want it done right, call (850) 303-7235. We’ll walk the roof ourselves, show you what we found, and hand you a written price before any work starts. Greg Holloway walks every Orlando roof we quote, and he’ll explain what he sees in plain terms.
