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

If your IKO shingles are failing because the underlayment beneath them gave out or the decking has rotted, we stock IKO-compatible underlayment and repair decks daily across Fort Worth. Most underlayment and deck repair jobs on IKO roofs in this area run $1,800 to $4,600 installed, depending on how many deck sheets need replacing and how much underlayment has to be pulled up. We can usually get out within 48 hours to assess it, and the written quote you get is the price you pay.

Here’s how most people find out: they spot a water stain on the ceiling after a hard North Texas storm, or they climb up to check the roof after a hailstorm and see shingles lifting where the underlayment has torn loose. The shingle looks fine from the ground, but underneath, the deck is spongy and the underlayment is shredded. That’s the part nobody sees until it’s too late.

Key takeaways:

• We install IKO-compatible underlayment and decking with written pricing before any work starts.
• Fort Worth’s hail and 100-degree summers kill underlayment faster than the national average.
• Every deck repair carries our 365-day written guarantee, including a free second visit if anything fails.

Which IKO Models This Applies To

This repair applies to any IKO asphalt shingle roof: the Cambridge, Dynasty, Nordic, and Marathon lines all sit on the same type of underlayment and decking. Whether your house went up with a builder-grade Marathon or a premium Dynasty, the failure pattern is the same: water gets past the shingle, the underlayment is the last line of defense, and the deck board is what rots when that defense fails.

One compatibility gotcha we see in Fort Worth: if your roof was installed before 2015, there’s a good chance the original underlayment was a lightweight felt product, not a synthetic or rubberized membrane. IKO’s current warranty guidance is clear that their shingles should sit on a proper underlayment rated for the pitch of your roof. If the original installer cut corners there, the shingles might still have five or eight years of life left, but the underlayment is done. We match the replacement to IKO’s specifications for your pitch and exposure, not just whatever was peeled off.

You don’t need to know your exact IKO model to call us. We’ll identify it from the shingle itself, the bundle wrap if you have one, or the original permit on file with the city. The part that matters for pricing is the square footage of decking that has gone soft and the condition of the underlayment across the rest of the roof.

Signs Your IKO Underlayment & Deck Repair Is Failing

• Water stains or bubbling on the ceiling after rain. This is the classic sign that water has made it past the shingles, through the underlayment, and into the deck. By the time it shows indoors, several square feet of decking are usually involved.
• Shingles lifting at the edges or sliding out of alignment. Underlayment holds the shingle in place when the adhesive strip fails. If you see shingles that look wrinkled or drifted, especially near the eaves, the underlayment underneath has likely torn or wrinkled.
• Soft spots or bouncy areas when walking the roof. A deck board that flexes underfoot is already compromised. In Fort Worth’s climate, that usually means repeated small leaks over several seasons, not one big storm.
• Granules collecting in gutters while the shingle looks thin or shiny. Granule loss is normal wear, but if it’s concentrated under specific shingles or heavy in one section, water has been sitting against the underlayment and the deck is at risk.
• A musty or damp smell in the attic after rain. Underlayment that has lost its water resistance holds moisture against the decking. That smell is the deck board slowly rotting under the surface.

Replacement Cost & What’s Included

In Fort Worth, underlayment and deck repair on an IKO roof runs $1,800 to $4,600 installed for most homes. The range comes down to three things: how many 4×8 deck sheets need to be pulled and replaced, how much underlayment has to be peeled back to expose the damage, and whether the area is straight decking work or includes valleys, penetrations, and eaves where the labor is slower.

Here’s the line-item breakdown we use:

• Deck sheet replacement: $95 to $140 per 4×8 sheet, including tear-out, new OSB or plywood, and fastening.
• IKO-compatible synthetic underlayment: $85 to $115 per 100 square feet installed.
• Ice-and-water shield in valleys and around penetrations: $65 to $95 per 100 square feet of coverage.
• Labor and site cleanup: included in the total, never billed as a separate line item.

We write the price down before we touch the roof. You know the number before we start, and that number doesn’t change unless the tear-off reveals something we genuinely couldn’t see from the surface, like a rotted rafter we point out and photograph for you. Even then, we don’t proceed without your sign-off. Every repair carries the 365-Day Done Right Promise: if that deck repair fails within a year, we fix it free.

DIY or Call Us?

You can safely check a few things from the ground or the attic: look for the warning signs above, shine a flashlight along the deck boards, and check for water trails after rain. That’s useful information when you call us, and it helps you understand the problem before anyone stands on your roof.

But this isn’t a patch job. Replacing decking and underlayment means working off a steep, often wet surface, pulling up shingles without damaging the good ones, and getting the fastening and lap spacing right so the IKO shingles above don’t fail prematurely. Getting it wrong doesn’t just leak: it voids the roof warranty and can cost twice as much to correct. We do this weekly across Fort Worth, we document every step with photos, and the work carries a written guarantee. If you’d rather watch from the ground, call (682) 730-3548 and we’ll schedule the free estimate.
