CertainTeed Home Additions & ADU: The Fort Lauderdale Owner’s Guide
CertainTeed siding, roofing, and trim products are common on Fort Lauderdale home additions and ADUs, and when a section fails or you’re planning new construction, matching the exact CertainTeed line matters. A full addition or ADU in Fort Lauderdale typically runs $45,000 to $130,000 installed, while a standalone ADU starts around $90,000 and can reach $220,000 depending on size, foundation work, and finish level. Most owners discover a problem after a storm, when they see warped siding, missing shingles, or water staining along a wall that ties into the original structure. We match existing CertainTeed products and install new ones the right way, with a written price before any work starts.
Here’s what we see on job sites across Fort Lauderdale: the original builder used a CertainTeed product line, something fails or the homeowner wants to expand, and now there’s a question about whether the new section will match the old one. That’s where a contractor who actually knows the product lines pays off.
Which CertainTeed Models This Applies To
CertainTeed makes several product families that show up on Fort Lauderdale additions and ADUs. The big ones are the siding lines: Monogram, Cedar Impressions, and MainStreet. Roofing is usually the Landmark or Independence shingle lines, plus the Flintlastic self-adhered system we see a lot on low-slope Florida roofs. Trim products run under the Restoration Millwork name. If you’re planning an ADU, the exterior cladding and roof need to either match your main house or stand on its own without looking like an afterthought.
How to identify what you have: check the underside of a siding panel, the back of a trim board, or the shingle packaging (if the installer left any). CertainTeed prints the product name and sometimes the manufacturing code right on the material. Siding panels are typically 12 feet long with a specific reveal depending on the profile: double 4-inch, double 5-inch, and so on. Getting the reveal wrong means your new section won’t line up with the existing course lines, and that looks bad from the street. For roofing, Landmark shingles have a specific exposure and the color names matter: Weathered Wood, Moire Black, Georgetown Gray. Matching a faded shingle is harder because Florida sun changes the color over time. We’ll tell you straight if a perfect match isn’t possible and what the closest option is. We’re an independent contractor, not affiliated with CertainTeed, but we install their products regularly and know where to source them in Fort Lauderdale.

Signs Your CertainTeed Home Additions & ADU Is Failing
- Warped or buckled siding panels. In Fort Lauderdale’s heat and humidity, vinyl siding that wasn’t nailed with the right expansion gap will buckle. The nails were driven too tight, and now the panels have nowhere to move when they expand.
- Water staining on interior walls where the addition meets the original house. This usually points to failed flashing at the transition, not the CertainTeed product itself. The seam between old and new construction is the first place water finds its way in during a South Florida downpour.
- Missing or cracked shingles after a storm. CertainTeed shingles are tough, but flying debris during hurricane season rips them loose. Once the seal strip breaks, adjacent shingles start lifting and you get a cascade of failures.
- Chalky residue washing off the siding. That’s normal for older vinyl and isn’t a structural failure, but it tells you the product is aging and replacement may be closer than you think. UV exposure in Fort Lauderdale ages siding faster than the manufacturer’s northern test data would suggest.
- Soffit or fascia pulling away from the roofline. This is often installation-related: the installer under-fastened or used the wrong fastener. In a high-wind event, that section catches air like a sail and tears loose.
Replacement Cost & What’s Included
For a full home addition in Fort Lauderdale, you’re looking at $45,000 to $130,000. That covers the structure, foundation, framing, roofing, siding, electrical, plumbing, drywall, and finishes. An ADU is a bigger project because of the separate utility connections and site work, so plan on $90,000 to $220,000. A garage conversion lands between $30,000 and $80,000. If you’re only replacing a section of CertainTeed siding or a roof tie-in, the number gets much smaller: a roof repair runs $400 to $1,800, and a roof replacement on the addition is $8,000 to $20,000.
What drives the range: size of the addition, the age of your existing structure (tying into an older Fort Lauderdale home usually means more surprises), whether you’re on a slab or have a crawl space, and the finish level inside. Every quote we write includes the full line-item breakdown before you approve anything. The 365-Day Done Right Promise applies to every addition and ADU project we complete: if it’s not done right, we make it right, in writing. No change orders that show up after the fact. The price we put in writing is the price you pay.

AfterDIY or Call Us?
There’s nothing a homeowner should DIY on a home addition or ADU. Not the framing, not the roof tie-in, not the electrical, and definitely not the structural work. Failing certain parts of this work puts people at risk: a roof that’s not tied into the existing structure correctly can pull away in a storm, and improper electrical work is a fire hazard. The safe things an owner can do: document what you have, take photos of the existing CertainTeed product labels, measure the affected area, and call us at (754) 354-7423 to talk it through. Luca Romano has been on plenty of Fort Lauderdale job sites where a homeowner tried to save money with a handyman, and the fix cost more than the original project would have. The work either holds up or it doesn’t: we make sure it does.
FAQs
A properly built addition with CertainTeed siding and roofing should last 30 to 50 years for the structure, with the roof needing replacement around 15 to 25 years depending on storm exposure and the shingle line. Fort Lauderdale’s salt air and UV load shorten exterior product life compared to inland areas, so count on the lower end of those ranges for anything facing the ocean. Call (754) 354-7423 if you want us to assess the condition of an existing addition.
Yes, in many cases a section of siding, soffit, or a roof tie-in can be repaired without replacing the whole addition, but the repair only makes sense if the surrounding material is sound. If the failure is a flashing issue or isolated storm damage, we can usually match and patch it. If the failure is widespread or the product is discontinued, replacement is the honest answer.
A home addition typically runs 8 to 16 weeks from permit approval to final inspection, and an ADU runs 4 to 8 months depending on utility work and the city of Fort Lauderdale’s permit schedule. We give you a written timeline before work starts along with the written price, and you get photo updates at every stage. Call (754) 354-7423 for a project-specific timeline.
We keep common CertainTeed siding profiles, trim pieces, and Landmark shingle colors on the truck for repair calls, and we source full addition and ADU materials direct from our local Fort Lauderdale suppliers. We also work with KraftMaid, Cambria, and Silestone for interior finishes, so the whole project comes from named brands, not mystery suppliers. Tell us what you have and we’ll tell you if we can match it.
