IKO Underlayment & Deck Repair Nationwide

IKO Underlayment & Deck Repair: The West Palm Beach Owner’s Guide

Underlayment and deck repair on an IKO roof in West Palm Beach typically runs between $950 and $2,400 installed, depending on how many deck sections need replacement and which underlayment you choose. We keep IKO-compatible underlayment rolls and decking materials on our trucks, so most repairs can be finished in a single visit. Most homeowners discover the problem after a leak starts, or when a roofer doing an inspection points out soft spots in the deck before a re-roof. If you’re seeing water stains on the ceiling after a Florida downpour, or your roofer mentioned “decking” during a quote, this page covers what actually happens next.

Which IKO Models This Applies To

IKO’s underlayment and deck system works across their entire asphalt shingle lineup here in West Palm Beach: Cambridge, Dynasty, Nordic, and Royal Estate. The underlayment itself is generally interchangeable across IKO product lines, but we check one thing before quoting: the slope of your roof. IKO’s synthetic underlayments (like their StormShield and RubrGard lines) have different fastening requirements depending on whether your roof is a 3:12 pitch near Northwood Village or a steeper 6:12 on a newer build out west near Wellington. If you have the original paperwork, look for the product name on the shingle wrapper or the warranty card. No paperwork? We identify the underlayment by the backing pattern and width, and we match the replacement to your existing system. We are an independent roofing contractor in West Palm Beach, not an IKO affiliate, so we can also recommend aftermarket equivalents from GAF, Owens Corning, or CertainTeed when they perform the same job for less money. IKO’s StormShield high-temp ice and water shield, for instance, is a solid product, but it’s overkill for most West Palm Beach roofs that never see ice. We’ll tell you when the premium product makes sense and when it doesn’t.

Signs Your IKO Underlayment & Deck Repair Is Failing

• Water stains on ceilings after heavy rain. In most West Palm Beach homes, this means the underlayment has worn through or a seam has opened. By the time water reaches drywall, the deck underneath is usually wet too.
• Soft spots or a spongy feel underfoot on the roof. This is deck rot. Florida’s humidity and afternoon thunderstorms mean wood decking in West Palm Beach fails faster than in drier climates, especially if the underlayment wasn’t sealed properly at the edges.
• Shingles lifting or curling at the eaves. The underlayment below has dried out or lost adhesion. IKO’s underlayments degrade faster with direct sun exposure at the roof edges, which is common on South Florida homes with minimal overhang.
• Granules collecting in gutters. Failed underlayment allows water to pool and saturate the shingle mat, which accelerates granule loss. If you’re seeing granules, the problem is usually underneath the shingles, not the shingles themselves.
• Visible cracks or tears in the underlayment during a re-roof. If you’re already replacing shingles in West Palm Beach and the crew finds the underlayment is brittle or torn, replacing it now saves you from a leak in two years.

Replacement Cost & What’s Included

The range we see in West Palm Beach for underlayment and deck repair is $950 to $2,400, and here’s what moves the number. A small repair of one deck panel with new underlayment is usually under $1,200. Replacing underlayment across half a roof pushes toward $1,800. Full deck replacement on a larger ranch or two-story home hits the top of the range. You’ll see a written price before any work starts, and that number doesn’t change. Erik Lindgren makes a point of this with every homeowner: the number on the page is the number on the final invoice. Every job includes shoe covers at the door, drop cloths through the hallway, and a clean-up photo before the crew leaves. The work comes with the 365-Day Done Right Promise, which means if the repair isn’t done right, we make it right.

DIY or Call Us?

You can safely check a few things from the ground: look for missing shingles, granules in the gutters, or water stains inside the home. What you should not do is climb onto a West Palm Beach roof in July to inspect underlayment yourself. Heat, steep slopes, and brittle decking make that genuinely dangerous. If the deck is already soft, putting weight on it can send you through. The underlayment inspection itself takes a trained eye, especially on IKO systems where seam failure is the most common issue and it’s easy to miss from the wrong angle. If you want to know exactly what’s wrong, call (728) 220-0842. We’ll come out, inspect, photograph what we find, and hand you a written price. That part costs you nothing.
