This page is for Miami homeowners who bought CertainTeed because they wanted a premium roof, and now need a roofing company that actually knows how those roofs behave in South Florida heat and hurricane weather. Grant Whitlock and our crew have torn off and replaced enough CertainTeed systems around Coral Gables, Kendall, Cutler Bay, and the Roads to recognize a CertainTeed problem by looking at it, not guessing at it.

How CertainTeed Products Fail – and How We Fix Them

CertainTeed makes a solid shingle. But Miami is hard on every roof, and CertainTeed products fail in specific, predictable ways here. Here’s what we see most often:

• Landmark PRO granule shedding in the first five years. CertainTeed’s Landmark PRO line carries heavier granules than the base Landmark, but Miami’s UV index bakes asphalt shingles faster than almost anywhere in the country. When the granule layer starts washing into your gutters after a hard rain, that’s the shingle’s UV protection leaving. We identify whether it’s normal wear, a batch issue, or installation-related, then replace affected slopes before the matting underneath starts cracking.
• Presidential Shake TL cupping and curling at the eaves. CertainTeed’s thick luxury shingle looks great on Coral Gables and Pinecrest homes, but its laminated layers trap more heat than a standard architectural shingle. We regularly see the bottom edge lift and curl on south-facing eaves where attic ventilation is weak. The fix is usually mechanical re-sealing plus ventilation correction, not a full roof replacement, which saves homeowners thousands.
• Flashing failures at CertainTeed skylight and pipe boot transitions. This isn’t a CertainTeed-specific defect, but Miami’s humidity and salt air corrode the metal flashings that tie CertainTeed shingles to penetrations faster than they do inland. We see rusted-through pipe collars and failed step flashing on 8- to 12-year-old roofs that still have plenty of shingle life left. Replacing the flashings and resealing the transition keeps a salvageable roof going for years.
• Symphony and XT 25 three-tab brittleness. CertainTeed’s entry-level XT 25 and older Symphony three-tab shingles get brittle fast in Miami’s heat cycle. A shingle that snaps when you bend it can’t survive a repair without cracking. When we’re called out for a patch job on one of these older lines, we’re honest about whether a repair will hold or whether the roof has reached the end of its service life.
• Carriage House and Grand Manor lifting at the leading edge. CertainTeed’s heavyweight designer shingles look beautiful, but their size and weight make them susceptible to wind lift if the original installer skimped on fasteners. Around Miami’s gusty summer squalls, we find whole sections that weren’t nailed to spec. The fix is re-nailing to the deck with correct fastener placement, which a surprising number of roofing companies skip because it’s tedious.

Our CertainTeed Roofing Company Process

When you call Mercer Roofing Co Miami about a CertainTeed roof, here’s exactly what happens:

1. 1
   The call. A live person answers, day or night. You tell us what you’re seeing: a ceiling stain, missing shingles, granules in the gutter. We schedule a visit and send you the technician’s name and photo before they arrive. When they knock, they’ll be in uniform with a photo ID badge.
2. 2
   The walk-through. The technician walks the roof with you or without you, whichever you prefer. They check the shingle condition, flashings, decking, and attic ventilation if it’s safe to access. On CertainTeed roofs, they’re specifically looking at granule condition, seal strip integrity, fastener patterns, and penetration flashings.
3. 3
   The written price. Before any work starts, you get a written, line-item price. No verbal estimate, no “we’ll see once we open it up.” If it’s a repair, the price includes the fix and the written guarantee. No work begins without your yes on paper.
4. 4
   The repair. We use OEM CertainTeed components where they’re available and genuinely better for the job, which is usually the case for shingle matching, ridge caps, and starter strips. For flashings and underlayment, we’ll use quality aftermarket options when they outperform or outlast the original spec for Miami conditions. We’ll tell you which is which and why before we install anything.
5. 5
   The check. After the repair, the technician tests the area for water resistance and confirms the repair is secure. You get a walk-through of what was done, what they found, and what to watch for going forward.
6. 6
   The paperwork. Every repair comes with Mercer’s written guarantee: if the repair fails within 365 days, we come back and make it right at no charge. That’s not a verbal promise. It’s in writing, on your invoice, every time.

What CertainTeed Roofing Company Costs in Miami

Miami roofing prices are driven by access, roof height, and what we find under the surface. Here’s what we typically see, in real dollars, for CertainTeed work:

• Small repair (single shingle patch, pipe boot reseal, minor flashing fix): $275 to $600, including materials, labor, and the written guarantee.
• Medium repair (multiple shingles replaced, valley flashing correction, chimney flashing reseal): $600 to $1,800, depending on roof pitch and access difficulty.
• Skylight flashing replacement: $400 to $950 per skylight, depending on type and deck condition.
• Ventilation correction alongside a repair: $250 to $700, depending on the number of vents and whether we’re cutting in ridge vents or installing box vents.
• Full CertainTeed roof replacement: $8,500 to $24,000 on the typical Miami home, depending on square footage, tear-off layers, decking replacement, and which CertainTeed line you’re installing. Landmark sits lower in the range; Presidential Shake sits higher.

The big variables are roof access (two-story with steep pitch costs more to work safely), decking rot we can’t see until tear-off, and whether you’re adding underlayment upgrades that Miami code or your insurer wants. We give you the exact number before work starts. Call (850) 753-2996 for a free estimate and Grant will give you a straight price.

Why Miami Homeowners Call Mercer Roofing Co Miami for CertainTeed Work

Most roofing companies in Miami can shingle a roof. Very few can tell you why your CertainTeed Landmark PRO is shedding granules three years in, or whether your Presidential Shake can be salvaged instead of torn off. We can, because we’ve worked on thousands of CertainTeed roofs across Miami and we know their failure points as well as we know our own trucks.

But the reason people stay with us is simpler. Every Mercer Roofing Co Miami technician is background-checked, identity-verified, and dispatched under the Threshold Verified standard. Their name and photo reach you before they do. They badge in with a photo ID at your door. You get a written price before a single nail is driven. And every repair is covered by a written 365-Day Done Right Promise: if it’s not right within a year, we make it right, at no charge. A roof shouldn’t be something you worry about – that’s our job. If your CertainTeed roof is giving you trouble, call (850) 753-2996. Someone real answers.
