IKO Underlayment & Deck Repair: The Orlando Owner’s Guide

IKO underlayment and deck repair in Orlando typically runs $450 to $1,800 installed, depending on how much decking has rotted and whether we’re replacing the underlayment across the whole roof or a single section. We stock IKO-compatible underlayment on our trucks and complete most deck repairs the same day we start. Most Orlando homeowners discover the problem two ways: a leak that stains the ceiling after an afternoon thunderstorm, or a roofer (us, usually, after they call) finds soft decking during a shingle replacement.

Here’s what’s happening under your shingles. The decking is the plywood or OSB layer nailed to your rafters. The underlayment is the water-shedding barrier between that wood and your shingles. IKO makes several underlayment products, and when either layer fails in Florida’s heat-and-humidity cycle, water finds the plywood. Then the plywood swells, delaminates, and you’re looking at a deck repair that could have been a simple underlayment swap if it’d been caught two years earlier.

Key takeaways:

• Most IKO underlayment failures in Orlando trace back to installation errors, not product defects; IKO’s synthetic underlayments are solid products when installed to spec.
• Deck repair means cutting out rotted plywood and replacing it, then re-nailing the section to code before underlayment goes back down.
• We give you a written line-item price before any work starts, and every repair carries the 365-Day Done Right Promise.

Which IKO Models This Applies To

IKO’s underlayment lineup includes their synthetic lines (StormShield, Stormtite, AquaBarrier) and traditional felt products (RoofGard, AMCO). The decking under all of them is structural, not brand-specific. The compatibility question matters most when matching underlayment to your IKO shingle system, because IKO’s high-end architectural shingles (Cambridge, Dynasty, Nordic) are engineered to work with their synthetic underlayments for the warranty to stay intact.

Here’s the gotcha most Orlando homeowners don’t know: if your original install used IKO felt and you’re replacing it with IKO synthetic mid-roof, you should also check the decking fastening pattern. Synthetic underlayment is thinner and slicker than felt, which means it telegraphs the deck’s condition more honestly. Wavy OSB that hid under felt shows up immediately under synthetic. We’d rather you know that before you commit.

If you can’t find the original underlayment brand, look in your attic near the eaves. The roof deck is visible from underneath in most Orlando homes (we don’t have the same rigid insulation encapsulation you see up north), and a flashlight will show you the underlayment label, the decking stamp, and any water staining you should know about. Greg Holloway walks every roof himself before quoting a number, and the attic check is part of that walk. No shorthand, no assumptions.

One honest note: Tilehurst Roofing Orlando is an independent service provider and not affiliated with IKO. We stock and install IKO-compatible materials because they’re a solid choice for Florida roofs, but we also carry GAF, Owens Corning, CertainTeed, Atlas, Tamko, and Boral. You get the product that fits the home, not whatever happens to be in the truck.

Signs Your IKO Underlayment & Deck Repair Is Failing

• Water stains on ceilings or walls after a storm. This is the classic. Underlayment’s job is to catch what gets past the shingles, and once it’s breached, the decking soaks through. Stains usually mean the deck has been wet for a while, not just once.
• Spongy or sagging areas when you walk the roof. Rotted decking loses its stiffness. If a section flexes underfoot, the wood is compromised and needs cutting out. In Orlando’s humidity, this happens faster than most homeowners expect.
• Granules from IKO shingles in your gutters. Excessive granule loss weakens shingle protection, which shifts more water load onto the underlayment. Age plus UV exposure in Orlando accelerates this. The underlayment wasn’t designed to handle that much water alone.
• Visible underlayment tears or exposed decking through missing shingles. After a wind event, check your roof from the ground. If you see white or black synthetic material flapping or plywood visible where shingles used to be, the waterproofing layer is exposed and needs attention now.
• Musty smell in the attic or visible mold on the underside of decking. Trapped moisture in the decking frame means the underlayment has failed and water has been sitting. Mold on OSB means replacement, not treatment. The wood’s structural integrity is already compromised.

Replacement Cost & What’s Included

For IKO underlayment and deck repair in Orlando, here’s what we’re seeing on real jobs:

• Small deck patch (1-2 sheets of plywood/OSB) with underlayment repair: $450 to $900
• Larger deck replacement (3-6 sheets) with new IKO synthetic underlayment over that section: $900 to $1,500
• Full roof deck replacement with complete IKO underlayment re-install: $1,500 to $4,500+, depending on roof size and how much framing needs attention

What drives the range: how many sheets of decking need replacing, whether we’re re-nailing to code (Florida requires 8d nails at 6-inch spacing on the perimeter and 12-inch in the field), the underlayment you choose (felt runs less than synthetic, IKO’s StormShield runs toward the higher end), and roof pitch. A steep second-story roof costs more in labor and safety setup than a low ranch in the Milk District.

Every quote includes parts, labor, disposal of the old material, and the written guarantee. We tell you the price before we touch the roof – and we mean it. No change orders. No “we found more once we opened it up” and then a bigger invoice. If we find hidden decking damage during the job, we show you a photo and get your sign-off before we proceed. The guarantee covers the repair for a full year under the 365-Day Done Right Promise, and if the repair fails inside that window, we return at no charge.

DIY or Call Us?

What you can safely do from the ground: look for missing shingles, visible underlayment flapping, and granule buildup in gutters. You can also check your attic for daylight coming through the deck, which tells you exactly where the roof is compromised. None of that requires a ladder.

What you should not do: walk a wet roof, climb a ladder with tools on an Orlando afternoon (the afternoon storms roll in fast and the decking gets slippery), or try to patch underlayment yourself. Decking repair means cutting out structural material while standing on the structure you’re cutting. If you miss a rafter, you’re going through. If you don’t seal the underlayment overlap correctly, the repair fails in the next storm. Florida’s code also comes into play here: improper deck repairs void your IKO warranty and create a liability if the roof fails later. This isn’t a job where “good enough” holds up.

If you’re not sure what you’re looking at, call us at (850) 303-7235. We’ll send someone out, walk the roof, and tell you what’s actually needed. The estimate is free, and you get a written number before any work starts.
