Tamko Home Additions & ADU Nationwide

Tamko Home Additions & ADU: The Fort Lauderdale Owner’s Guide

We stock and install Tamko-compatible components for home additions and ADU projects in Fort Lauderdale, with typical installed pricing from $45,000 to $130,000 for additions and $90,000 to $220,000 for detached ADUs. Most homeowners discover issues during the rough-in phase, when a mismatched roof-to-wall transition or an incompatible underlayment specification reveals the original Tamko documentation didn’t account for Florida’s wind-borne debris requirements. Our crews carry Tamko Heritage series shingles, Titan XT impact-rated options, and the correct peel-and-stick underlayment for Fort Lauderdale’s HVHZ compliance zone.

Which Tamko Models This Applies To

The critical compatibility issue for Fort Lauderdale additions and ADUs isn’t the shingle line itself, it’s the wind rating assembly. Tamko’s Heritage series carries a 130 mph wind warranty with standard six-nail application, but in Broward County’s High Velocity Hurricane Zone, your addition or ADU roof assembly must meet Florida Product Approval or Miami-Dade NOA standards. We see this mismatch most often when a homeowner sources Tamko shingles independently and discovers the specific color or weight class lacks the required NOA documentation for permit approval.

To identify what you have, check the bundle label for the Florida Product Approval number, typically formatted FLxxxxx, or the Miami-Dade NOA reference. The Titan XT line carries HVHZ approval standard, while some Heritage colors do not. For the roof-to-wall transitions common in second-story additions, we stock Tamko’s approved peel-and-stick underlayment in 36-inch and 48-inch rolls, matching the slope requirements of your existing structure. OEM Tamko accessories are our default, though we also carry Atlas and CertainTeed equivalents where the lead time on Tamko-specific flashing is running long. Measure twice, write it down, then say it once.

Signs Your Tamko Home Additions & ADU Is Failing

• Granule loss visible in gutters or downspout elbows. Tamko shingles shedding granules at an accelerated rate, common in Fort Lauderdale’s UV exposure and salt-air environment, expose the asphalt substrate to premature cracking. We document this with close-up photos showing the bald patches and measure remaining granule depth against the manufacturer’s spec.
• Lifted or creased shingles along the addition’s valley or ridge lines. Thermal cycling in Fort Lauderdale’s afternoon thunderstorms creates expansion-contraction stress at the attachment points; creasing indicates the shingle has flexed beyond its design limit and the sealant strip has failed.
• Water staining on interior drywall where the addition ties into the existing roof. This typically traces to an improper step-flashing detail or Tamko’s approved ice-and-water barrier being omitted at the wall intersection, a code requirement we verify during tear-off.
• Soft or spongy decking when walked during inspection. In Fort Lauderdale’s humidity, a failed Tamko underlayment allows moisture to saturate OSB or plywood decking within 18 to 24 months of installation; we probe with an awl and photograph the decay pattern for the photo record.
• Shingle tabs that no longer lie flat after a wind event. The self-sealing asphalt strip on Tamko shingles activates with solar heat; if the seal fails, Fort Lauderdale’s routine 40 to 50 mph afternoon gusts will lift and fatigue the tab until it tears.

Replacement Cost & What’s Included

What drives the range: existing structure condition, whether the addition requires foundation work in Fort Lauderdale’s coral rock substrate, and the complexity of tying into the existing roofline. Every quote from Rowan Construction Group lists material brands by name, including the Tamko series and any KraftMaid cabinetry, Cambria or Silestone surfaces specified for interior finishes. Under Clause 1 of the Haven Standard, the written price arrives before any work starts; no change proceeds without a signed change order. Our 365-Day Done Right Promise covers the installation, and the documented photo record shows you every layer before it’s covered.

DIY or Call Us?

An owner can safely verify the Tamko bundle labels and photograph any visible damage from the ground or a secured ladder. What you cannot safely assess is the decking condition beneath the shingles, the integrity of the peel-and-stick underlayment at critical intersections, or whether the existing assembly meets current Fort Lauderdale building code for HVHZ compliance. We do not recommend homeowner tear-off on any roof surface above six feet, and we do not recommend attempting to match a Tamko roof-to-wall flashing detail without the specific NOA-approved installation sequence. The permit inspection will fail if the fastening pattern or underlayment overlap is incorrect, and the rework costs more than doing it properly the first time. Call (754) 254-7676 and we’ll scope it, photograph it, and put the number in writing.
