IKO Underlayment & Deck Repair Nationwide

IKO Underlayment & Deck Repair: The Fort Lauderdale Owner’s Guide

IKO underlayment and deck repair in Fort Lauderdale typically runs $450 – $1,900 installed, depending on how much of the roof deck has rotted and which IKO underlayment you’re replacing. We stock IKO-compatible underlayment on our trucks and can usually complete a standard repair the same day we diagnose it. Most homeowners discover the problem after a leak shows up on the ceiling, or when a roofer doing a shingle replacement peels back the old material and finds the deck underneath has turned to mulch. In Fort Lauderdale, with our humidity, afternoon downpours, and hurricane-season wind-driven rain, a failed underlayment doesn’t stay hidden for long. The water finds a way in, and then it’s a race between the repair and the mold.

Which IKO Models This Applies To

If your roof has IKO shingles, the underlayment beneath them could be one of several IKO products: RoofGard-Cool, RoofPro, or the ArmourGard synthetic line. The specific underlayment matters less than the condition of the deck beneath it, but we do match material when the roof is newer. If your home still has the original underlayment from an older IKO Cambridge or Dynasty install, it’s likely a felt-based product that’s nearing the end of its useful life in South Florida’s climate.

Here’s the compatibility gotcha most homeowners don’t know: IKO’s synthetic underlayments have different exposure ratings, and mixing a high-exposure synthetic with an older felt system creates uneven protection at the overlaps. We see this on patch jobs done by other crews. For IKO roofs specifically, we recommend staying within the same product family rather than mixing a bargain aftermarket roll with an IKO system. The aftermarket synthetics work, but the warranty math gets murky. We’re an independent contractor, not affiliated with IKO, but we install to their spec so the material warranty stays intact.

Signs Your IKO Underlayment & Deck Repair Is Failing

• Ceiling stains that darken after rain. This is the classic first sign. Water has breached the underlayment and is now traveling along the deck before dripping through. The stain usually appears feet away from the actual breach, which is why guessing the source without pulling shingles is a fool’s game.
• Granules in your gutters after every storm. IKO shingles lose granules as they age, but if the underlayment is failing, the shingles above it move more, accelerating the granule loss. Excessive granules mean the whole system is shifting.
• Soft spots you can feel from inside the attic. If you can press a screwdriver into the deck and it sinks, the plywood or OSB has absorbed water and lost its structural integrity. This is a deck replacement, not a patch.
• Daylight visible through the attic boards. Underlayment isn’t structural, but when it’s gone, the deck is exposed. Any gap or crack that lets light through is a direct path for water.
• Mold or mildew smell in the attic after humid weeks. Fort Lauderdale’s humidity means a small leak doesn’t dry out on its own. The deck stays damp, and that dampness feeds mold long before you see a stain on the ceiling.

Replacement Cost & What’s Included

Most standard IKO underlayment and deck repair jobs in Fort Lauderdale run $450 – $1,900 installed. A simple underlayment replacement over a sound deck sits at the lower end. If we’re replacing rotted deck sections, the cost climbs with the square footage of plywood or OSB we have to cut out and reinstall. Full deck replacement on a large roof can push past that range.

Every quote includes the same line items: tear-off of the affected area, deck inspection and replacement as needed, new IKO-compatible underlayment installed to manufacturer spec, shingle reinstallation or replacement, and full cleanup. The written price you get before work starts is the number on the invoice. No change orders, no “we found more damage” upcharges after we’ve already opened the roof. If we do find something unexpected, you’ll see it in photos before you approve a single extra dollar. Every repair carries the 365-Day Done Right Promise: if it fails within a year, we come back and fix it at no charge. That’s in writing, included with every job.

DIY or Call Us?

A homeowner can safely check a few things: look for ceiling stains, peek into the attic on a sunny day for visible light gaps, and run a hand along the deck boards near any known leak to feel for softness. Those checks tell you the scope of the problem, not the fix.

What you shouldn’t do is climb onto a Fort Lauderdale roof in July, peel back IKO shingles, and start swapping underlayment. Walking a roof without proper training and safety gear is how people end up in the ER. Underlayment replacement means exposing the deck to the elements, and if a storm rolls in before the new material is sealed, you’ve turned a $600 repair into a $6,000 water damage claim. Our techs are background-checked and uniformed, so you know exactly who’s arriving before they pull into your driveway. If you’ve found signs of failure, call (754) 354-8628. We’ll diagnose it, quote it in writing, and you’ll see before-and-after photos of the work.
