Why Orlando Homeowners Choose CertainTeed Roofing
Mercer Roofing Co Orlando provides Orlando Certainteed service for independent roofing repair and installation, and we’re one of the few local crews that will tell you exactly what’s failing on your CertainTeed roof before we ever pick up a tool. Every tech who shows up at your door is background-checked, photo-badged, and familiar with CertainTeed’s specific product lines, from Landmark architectural shingles to Presidential Shake TL. We are not authorized by CertainTeed, and that’s deliberate: our recommendations come from what actually holds up in Central Florida’s storm cycles, not from a factory playbook. Call (850) 757-3564 to talk through what you’re seeing.
Why Trust Mercer Roofing Co Orlando for Your CertainTeed Roofing?
CertainTeed roofs fail in predictable ways here in Orlando. The heat, the afternoon thunderstorms, the hurricane gusts: each one leaves a specific signature on the shingles and flashing. Our crew has spent years reading those signatures on CertainTeed roofs across Lake Nona, Conway, and Certainteed in Sanford and the older subdivisions around Pine Castle. Grant Whitlock, our owner, trained at Los Angeles Trade-Technical College and has nearly two decades of hands-on roofing behind him, and he makes sure every tech on the crew knows the difference between a Landmark tab that lifted from wind and one that was never sealed properly at install. That’s the kind of distinction that changes whether you pay for a spot repair or a full replacement.
We stock genuine CertainTeed shingles and accessory components locally, so color lot consistency and profile matching are not a guessing game. When an aging XT 25 starts shedding granules, we can source matching three-tab bundles or tell you honestly that the roof has hit the point where patching is throwing money at a problem. Being independent means we’ll give you the answer we’d want on our own house, in writing, with a price attached before any work starts.

Common CertainTeed Roofing Problems We Fix in Orlando
Here’s what we actually see on CertainTeed roofs across Orlando, week after week:
- Cracking and granule loss on CertainTeed XT 25 three-tab shingles. The XT 25 was a workhorse three-tab, but after 15 to 20 years of Central Florida UV exposure, the asphalt dries out and the surface cracks along the tab lines. Granules end up in the gutters in handfuls. By the time you’re seeing bare fiberglass mat, the shingles are past repair and the roof needs section or full replacement.
- Wind uplift and tab separation on CertainTeed Landmark architectural shingles. Landmark shingles have a two-layer laminated design that resists wind well, but after tropical storm gusts, we regularly find tabs that lifted and never re-sealed. The heat softens the sealant strip, and a strong enough gust can peel it free. Once that seal is broken, the next storm gets under it and the damage spreads quickly.
- Chalking and surface erosion on CertainTeed Presidential Shake TL. The Presidential Shake is a thick, luxury shingle, but in attics that run hot, the surface binder breaks down into a chalky white film. It looks worse than it is, but it signals the shingle’s UV resistance is spent. We check the attic ventilation when we see this: often the fix is more airflow, not just shingle work.
- Leaks at valley metal transitions on CertainTeed tile and metal roof systems. Under every CertainTeed tile or metal valley, there’s an underlayment doing the real waterproofing. After 12 to 15 years in Orlando’s humidity, that underlayment can age out while the tile above it still looks fine. We see the telltale staining at the valley edges and know the water’s been getting under the metal for months before it showed up on the ceiling.
- Pipe boot collar failures. This one’s not the shingles; it’s the flashing. After a fast-moving afternoon thunderstorm, our crew responded to a home in the Conway area where an original CertainTeed Landmark roof was leaking around a pipe boot. The rubber collar had cracked from heat and UV exposure, letting water run straight down the vent pipe into the attic. We replaced the boot with a new corrosion-resistant flashing assembly, re-sealed the surrounding shingles, and confirmed the decking was still sound. A $300 fix instead of a $3,000 ceiling repair.
CertainTeed Parts & Our Repair-vs-Replace Approach
For active CertainTeed lines like Landmark and Presidential Shake, we source genuine CertainTeed shingles and tiles from local distributors so the color lot matches and any remaining manufacturer warranty stays intact where it applies. For discontinued styles or isolated repairs on older roofs, we’ll find a high-quality aftermarket match that mirrors the original profile and color as closely as possible. We’ll tell you which one you’re getting, and why.
The repair-vs-replace decision-one we handle through our Roof Repair services-comes down to two questions: how much roof life is left, and how likely the same failure is to repeat. A cracked tile on a 5-year-old Grand Manor roof? Replace the tile. Granule loss across 60% of a 22-year-old XT 25 roof? Repairs become a monthly subscription, and we’ll say so plainly. You get a written price before any work starts either way. Call (850) 757-3564 and we’ll put eyes on it.
Our CertainTeed Service Process — Step by Step
- 1
Diagnosis. We inspect the specific failure point: shingle condition, flashing integrity, underlayment status, and the roof-to-wall connections that Florida wind codes care about. For CertainTeed roofs, we check the sealant strips on Landmark tabs and the valley transitions on tile systems.
- 2
The written price. Before any work starts, you get a line-item quote in writing. Not an estimate range, not a handshake number. The price we quote is the price you pay. No change orders unless you ask for more work.
- 3
Repair or install. We use genuine CertainTeed components where the line is still active, matched aftermarket where it’s not. Every shingle, tile, and flash boot goes in per the manufacturer’s nailing and sealing specs, plus the Florida Building Code requirements for wind uplift.
- 4
Test. After the work, we water-test the repaired area and check the surrounding shingles for any we disturbed. On tile work, we confirm the replacement tiles are seated and the underlayment at the edges is sealed.
- 5
Warranty. Every repair includes our written guarantee: 365 days, in writing, and a free second visit if the repair fails. That’s the 365-Day Done Right Promise, and it’s part of every job we do in Orlando.

AfterCertainTeed Products We Service & Install in Orlando
We work on the full range of CertainTeed roofing systems you’ll find across Orlando, including CertainTeed Roofing in Alafaya, FL,: Landmark architectural shingles in the planned communities, XT 25 three-tabs on older homes from the 1970s and 80s, Presidential Shake TL on higher-end custom builds, and Grand Manor luxury shingles where the profile matters as much as the protection. We also handle CertainTeed tile and metal roof systems and their underlayment layers. Locally, we keep Landmark bundles and common accessory parts stocked for quick turnaround. Special-order colors and discontinued profiles take a few extra days, and we’ll tell you the timeline before you commit.
We Also Service These Brands
We’re not tied to one manufacturer. Mercer Roofing Co Orlando installs and repairs GAF, Owens Corning, IKO, Atlas, Tamko, and Boral systems too. That matters because our advice on your CertainTeed roof isn’t filtered through a single-brand lens. If your best fix is a different product, we’ll tell you.
FAQs — CertainTeed Roofing Service in Orlando
No, we are an independent CertainTeed service provider, not a factory-authorized installer or warranty agent. That independence is the point: our recommendations are driven by what keeps Orlando roofs performing, not by manufacturer quotas.
Yes, whenever the product line is still active. For Landmark, Presidential Shake, and current tile lines, we source genuine CertainTeed shingles and accessories from local distributors to keep color lots matched and warranty eligibility intact where it applies. For discontinued lines like certain XT 25 colors, we source the closest high-quality aftermarket match and tell you upfront.
Almost always, yes. Landmark’s laminated design means isolated tab damage, a few missing shingles, or a failed flashing boot can be spot-repaired cleanly. We match the color lot as closely as the available stock allows. If the surrounding shingles are too brittle to lift and re-seal, we’ll tell you a section replacement makes more sense.
Some granule loss is normal as shingles age, but heavy shedding where you see bare fiberglass mat or wide cracking means the shingles are at the end of their service life. In Orlando’s UV, XT 25 three-tabs typically reach that point around 15 to 20 years. We’ll inspect and tell you honestly whether you have repair years left or replacement is the right call. Call (850) 757-3564 for a free estimate.
Most spot repairs are done in a single visit, often the same week we diagnose. Full roof replacements on CertainTeed Landmark roofs in Orlando typically take two to five days depending on roof size, decking condition, and weather. We give you a written timeline with your written price before any work starts, and we keep you posted on any weather delays.
Spot repairs on CertainTeed roofs in Orlando typically run $250 to $800 depending on what’s failed and how much material is needed. Full replacements with Landmark architectural shingles generally fall between $14,000 and $24,000 for an average Orlando single-family home, with Presidential Shake and Grand Manor runs higher. The exact number depends on your roof’s size, decking condition, and the accessories involved. Call (850) 757-3564 and we’ll give you a written line-item quote, not a ballpark.
