CertainTeed Home Additions & ADU: The Fort Lauderdale Owner’s Guide
If you’re planning a home addition or ADU in Fort Lauderdale and want CertainTeed materials used the right way, we install CertainTeed siding, roofing, insulation, and trim as part of full home additions and accessory dwelling units. Typical project costs in Fort Lauderdale run $45,000 to $130,000 for home additions and $90,000 to $220,000 for ADUs, depending on square footage, foundation work, and finishes. What most owners discover too late is that the CertainTeed components are only as good as the framing and waterproofing behind them, and that’s where a Fort Lauderdale-specific build matters.
Most homeowners don’t search for “CertainTeed parts” until something has already gone wrong. They notice water staining at a corner, siding that’s warped or pulling away from the wall, or a roof section that sags after a storm. Or they’re mid-planning on an ADU and realize the contractor they talked to couldn’t answer basic questions about CertainTeed product compatibility. Either way, you’re here because you want specifics, not a sales pitch.
Which CertainTeed Models This Applies To
CertainTeed divides its exterior products into product families that are not interchangeable in the field. On the siding side, that means Monogram, Cedar Impressions, MainStreet, and Board & Batten lines. Each has different thicknesses, nailing flanges, and expansion tolerances. On the roofing side, Landmark, Presidential Shake, and Grand Manor shingles have different exposure widths and fastening patterns. In Fort Lauderdale’s humidity and storm-driven rain, mixing Series lines on one wall or roof plane is a common cause of premature failure we get called to correct.
The best way to identify what you have is to look for the product code printed on the back of a siding panel or on the shingle wrapper, often a series of letters and numbers stamped near the nailing line. If you’re missing that, we match by profile, thickness, and lock geometry. For an ADU or home addition, we specify products from the same CertainTeed family already on your main house so the addition doesn’t look like an afterthought. And we don’t push aftermarket equivalents when the OEM product is still in production and reasonably priced. For older CertainTeed lines that have been discontinued, we find the closest current-series match and tell you plainly what the difference will look like.

Signs Your CertainTeed Home Additions & ADU Is Failing
Here’s what we see in Fort Lauderdale when CertainTeed-installed work goes wrong, and what’s usually happening behind the surface:
- Siding buckling or waving along the wall plane. This usually means the panels were nailed too tight, leaving no expansion room. CertainTeed vinyl and polymer siding expands and contracts more than people expect in South Florida heat. The fix is often re-fastening, not replacing, but it needs to be caught early.
- Water staining at inside corners or around window trim. For home additions, this typically points to missing or poorly lapped flashing behind the CertainTeed siding or around the roof-to-wall transition. The siding itself is rarely the problem; the layer behind it is.
- Shingle granule buildup in your gutters after every storm. CertainTeed shingles shed some granules when new, but steady loss after the first year means premature wear, usually from attic heat or poor ventilation under a Fort Lauderdale sun.
- Soft spots in the wall sheathing when you press from inside. By the time you feel this, water has been getting behind the siding for months. This is the most expensive repair because it means pulling siding, replacing sheathing, and re-flashing the entire section.
- Visible daylight through the siding seams at certain angles. If you can see the house wrap or felt behind the siding locks, the product wasn’t installed with proper overlap. This is a re-installation job, and in some cases the panels have to be replaced once they’ve been pried off.

AfterReplacement Cost & What’s Included
In Fort Lauderdale, replacing failed CertainTeed siding on one wall of a home addition typically runs $4,500 to $14,000 installed, depending on the product line, wall height, and whether sheathing has to be replaced. A partial roof repair where CertainTeed shingles have failed prematurely runs $1,500 to $8,000 depending on the number of squares and decking condition. Full home addition and ADU projects using CertainTeed products from the start run $45,000 to $130,000 and $90,000 to $220,000 respectively.
What’s included when we do the work: removal and disposal of the failed material, inspection and replacement of any rotted sheathing or damaged flashing behind it, installation of the correct CertainTeed product matched to your existing line, and a written guarantee on the workmanship with clearly stated terms. We deliver a written price before any work starts, which means you know exactly what you’re paying before we pull the first panel. No change orders, no surprise invoices.
DIY or Call Us?
CertainTeed siding and roofing work is not a high-tension danger like garage door springs, but it is not a weekend project either. You can safely check your own siding for loose panels, visible gaps, and granule buildup, and you can document what you find with photos. What you shouldn’t do is start pulling panels to “see what’s behind them.” Once a panel comes off, the water-resistive barrier behind it is exposed to Fort Lauderdale’s humidity and afternoon storms, and an unsealed opening becomes a leak within days.
Roof work is another line we don’t cross into DIY territory. Walking a CertainTeed shingle roof without proper fall protection, especially on a two-story Fort Lauderdale home, is how people get hurt. If you suspect a leak or granule failure, call us at (754) 354-3720. We tell you what we found, what it takes to fix it, and what it will cost, before we touch a thing.
FAQs
CertainTeed siding products generally carry lifetime limited warranties, but in Fort Lauderdale’s heat, salt air, and hurricane exposure, the realistic service life of the installation, not the product, is what matters most. We see properly installed CertainTeed siding holding up 30+ years here. Poor installation can cut that to under 10. The warranty on the product doesn’t cover labor or installation errors, which is why we put our own written guarantee on every job for 365 days from the completion date with clearly stated terms.
Yes, in most cases a single panel or a short run can be replaced, as long as we can match the product line and color. CertainTeed colors are mixed in batches, so older panels may have faded slightly. We match as closely as possible and tell you if the difference will be visible before we order anything. Call (754) 354-3720 for an exact quote, estimates are free.
Most single-wall siding repairs or partial roof repairs take one to two days on site, depending on how much hidden damage we find behind the failed material. Full home additions and ADUs in Fort Lauderdale typically run three to six months from permitting to final inspection. We pull permits, schedule inspections, and keep the job site as clean as we’d want it if it were our house.
We keep fast-moving CertainTeed trim, corners, J-channel, and starter strips in common colors on the truck or in our Fort Lauderdale yard. For full siding panels, specialty shingles, or custom-color orders, we order directly from our supplier, usually with a few days’ lead time. We can also source KraftMaid cabinetry, Cambria countertops, and Silestone surfaces for the interior side of your home addition or ADU.
