IKO Underlayment & Deck Repair Nationwide

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

If your IKO shingle system is failing from the deck up, we stock and install IKO-compatible underlayment in Orlando, and typical deck repair and replacement runs $850 to $2,400 depending on how much sheathing needs to come out. Most underlayment-only work lands between $1,100 and $1,800 for an average Orlando roof slope, and we can usually get a crew to you within a few days, not weeks. The way Orlando homeowners discover this problem is almost always the same: a shingle blows loose, they climb up or a roofer gets eyes on the deck, and the plywood underneath is soft, dark, or delaminating. By then, the underlayment has been quietly failing for a while.

Which IKO Models This Applies To

IKO’s lineup splits into three families that matter for underlayment and deck work: the Cambridge architectural series, the Dynasty premium architectural line, and the Nordic performance shingle. Each sits on a different deck tolerance. Cambridge and Dynasty install over standard 3/8-inch or 1/2-inch plywood or OSB, while Nordic’s heavier construction means the deck gets inspected harder for deflection, edge support, and fastener hold. Here’s the gotcha most Orlando roofers won’t mention: IKO’s installation instructions require specific underlayment fastening patterns per wind zone, and Central Florida sits in a high-wind zone where cap nails or staples every 6 inches on laps is the minimum, not the recommendation. If your existing underlayment was installed with 12-inch stagger spacing, it voids the warranty and explains a lot about why you’re replacing it early.

We are an independent Orlando roofing contractor, not affiliated with IKO, but we install their full accessory line including IKO’s StormShield and AquaBarrier synthetic underlayments. For deck repair, OEM doesn’t really apply in the way it does with shingles. What matters is matching deck thickness to the original build and using an underlayment rated for IKO’s fastening schedule. We stock both IKO-branded underlayment and quality equivalents like GAF Deck-Armor or Owens Corning ProArmor when a homeowner wants a cross-compatible option.

Signs Your IKO Underlayment & Deck Repair Is Failing

• Dark stains bleeding through roof sheathing joints in the attic. This means water has saturated the deck and is wicking through the plywood. The underlayment has already failed somewhere above, and the staining tells you exactly which deck sections to plan for replacement.
• Visible sag between rafters from inside the attic. Plywood and OSB lose stiffness when they have been wet more than once. A deck that deflects under your hand is not going to hold IKO shingles flat through the next storm, and it is a tear-off situation, not a patch.
• Granule loss collecting in gutters with no shingle edge wear. When the deck moves, shingles flex, and granules shear off from the backside even though the top face looks fine. This is a deck stability issue masquerading as a shingle issue.
• Shingles lifting along an entire row or ridge line after a normal afternoon storm. If your IKO shingles are nail-anchored to decaying sheathing, the whole field can loosen at once. Fasteners lose pullout resistance in rotted OSB long before the shingle itself fails.
• Soft, spongy feel when walking the roof, especially near valleys, eaves, and pipe boots. Those are the three highest-traffic water intrusion points on an Orlando roof. If the deck is soft there, expect to replace at least a 4-by-4 section at each location.

Replacement Cost & What’s Included

For an average Orlando single-story home, expect honest numbers like these when we quote IKO underlayment and deck repair:

Those numbers include tear-off of failed material, haul-away, new underlayment, and labor. What moves the price is deck condition: if the first sheet comes up and the rot runs three sheets deep, we show you photos before we proceed and give you a written price for the added scope before any additional work starts. That is the part most Orlando roofers skip. We do not want you finding out the final bill changed after the fact. Every repair also carries our 365-Day Done Right Promise, which means the underlayment and deck work we just installed is covered in writing for a full year, including a free second visit if anything fails.

DIY or Call Us?

Here is the honest split. An Orlando homeowner can safely check their attic for water staining on a dry weekend, and you can walk your roof edge from the ground with a pair of binoculars and note where shingles look lifted. What you should not do is cut into a failed roof deck without the right fall protection, and underlayment installation done incorrectly will void whatever IKO warranty you thought you still had. Walking a compromised deck is exactly how a homeowner falls through. If you see soft spots, dark staining, or shingles lifting after the last storm, the best next step is a professional deck inspection, and we will show you photos of every problem area before we touch anything. Call us at (448) 218-0800 and we will send someone who will not upsell you a roof replacement over a deck repair.
