Wind Damage Roof — Underlayment Was Missing From the Estimate

This was part of a wind damage roof where multiple facets were affected and the insurance company agreed to replace the entire roof. The issue wasn’t approval — it was the estimate. On paper, the adjuster only wrote for removing and replacing shingles and included a dumpster, but critical components of the roofing system were missing. One of those items was the underlayment.

The Situation

The roof was being fully replaced due to wind damage.

This was a full tear-off, meaning everything down to the decking was being exposed and rebuilt. Once you get to that point, the underlayment becomes one of the most important layers in the entire system.

What Was Written

The adjuster initially wrote for:

• remove and replace shingles

• dumpster / debris removal

There was no mention of underlayment anywhere in the estimate.

What Was Missed

The underlayment was completely missing.

This includes:

• full coverage across the roof deck

• proper fastening method

• correct installation sequence beneath shingles

This is not optional.

It is a required layer of the roofing system.

What Most People Miss

Underlayment is what sits between the shingles and the roof deck.

👉 It is your secondary water barrier

There are typically two types used today:

• #30 felt (asphalt-saturated felt paper)

• synthetic underlayment (breathable sheet material)

Both serve the same purpose:

• protect the deck during installation

• provide backup protection if water gets under shingles

But how it’s installed matters just as much as what it is.

In many states, especially high-wind areas like Florida:

👉 you cannot just staple underlayment

It must be:

• fastened with cap nails or cap staples (buttons)

• installed in a specific fastening pattern

This is to prevent blow-off before shingles are installed.

And here’s another important part:

👉 some states require an inspection before shingles even go on

In Florida, for example:

• the roof must pass a dry-in (underlayment) inspection

• before the final roofing material is installed

Other states:

• may not require this

• only perform a final inspection

So requirements vary.

Structural Note (Often Overlooked)

At this stage, if any decking is replaced:

• it must be properly fastened into rafters or trusses

• nail spacing and placement must meet code

In stricter areas:

• missed framing members

• incorrect fastening patterns

👉 can result in inspection failure

This is how precise roofing installation actually is.

What Changed the Outcome

Once it was explained:

• that the roof was being fully replaced

• that underlayment is a required system layer

• and that installation methods vary by code and region

👉 it was added to the estimate and approved

Why This Happens

This happens because underlayment is not visible once the roof is finished.

The adjuster sees:
👉 shingles

The contractor sees:
👉 layers that make the system work

Underlayment sits in the middle of that system, so it’s one of the most commonly missed items.

What Homeowners Should Look For

If your roof is being replaced, check your estimate for:

• full underlayment coverage

• type (felt vs synthetic)

• fastening method (especially in high-wind areas)

• whether local code requirements are being followed

If it’s not listed:

👉 it’s not included

Takeaway

Shingles are not your only protection.

👉 underlayment is what protects your roof when shingles fail

And how it’s installed matters just as much as having it there.

If it’s missing from the estimate:

👉 the roofing system is incomplete

And this is where it goes wrong.

One Last Thing (What Everything Comes Down To)

Everything comes down to the estimate.

If your claim is delayed, underpaid, or being pushed back, that’s usually the reason.

If you’re not finding a clear answer to your situation here, go through the other case studies. Most real-world claim problems — and how they were handled — are already shown there.

And if your estimate is in good shape, the other issues tend to be straightforward to push through.
