Moisture Survey for Roof Restoration – and the Warranty That Protects It

Commercial Roof Restoration

Pre-Restoration Surveys and Manufacturer Warranty Documentation for Contractors

Whether you’re applying a fluid-applied restoration (roof coating) or installing a single-ply membrane overlay, the outcome of that project depends on one thing the finished product can’t fix: the condition of the insulation underneath. Wet insulation at the time of application is one of the most common causes of premature restoration failure, and it’s the reason manufacturers require a dry substrate as a condition of issuing a warranty.

Moisture Survey Pros provides the pre-restoration moisture surveys that confirm your substrate is ready, and delivers the certified documentation that manufacturer warranty programs often require. For many contractors, this is the same deliverable: the survey report that goes into the warranty application file.

Why Wet Insulation Makes Restoration Warranties Voidable

Fluid-applied coatings and overlay systems are designed to bond to a stable substrate. Wet insulation expands and contracts with temperature cycles, working against the new system from below. When trapped moisture evaporates, the resulting steam has no where to go and will create additional pressure within the system until it is released. The result is blistering, delamination, and failure that will appear in the same areas where moisture was present at the time of application.

Manufacturers know this. Their warranty conditions are explicit: the existing insulation must be substantially dry before installation, and in many programs, the contractor must upload documentation of a pre-installation moisture survey as part of the warranty application. Without that documentation, the warranty may be conditional, reduced, or denied entirely if a claim is ever filed.

Fluid-Applied Restoration Coatings

Before a silicone, acrylic, polyurethane, or similar fluid-applied system is applied, the existing roof system needs to be evaluated. Our survey identifies wet zones that must be removed and replaced before coating, protecting the integrity of the finished system and satisfying the manufacturer’s installation requirements.

Single-Ply Membrane Overlays

Installing a new membrane layer over wet insulation traps that moisture in the assembly permanently. This leads to the same failure patterns over time and is often a line item within a manufacturer system warranty that can void coverage. A pre-installation survey gives you a documented baseline and identifies any areas requiring remediation or replacement before the new membrane goes down.

What the Survey Delivers

A complete map of the roof showing the temperature differential between wet and dry areas. This is produced by drone-mounted infrared cameras that fly after civil sunset.
Probe testing withing anomalous areas identified in the infrared thermography to produce quantitative moisture readings.
Optional impedance moisture mapping on the roof system to identify and mark areas where the insulation will need to be remediated or removed.
Photos and data from the dates of inspection.

Using the Report for the Warranty Application

Many manufacturers that offer roof coating and overlay warranties have a specific process for warranty application that includes uploading supporting documentation. Our reports are formatted to meet the documentation standards that many of these programs require: certified thermographer credentials, equipment details, survey conditions, methodology, and findings with photographic and thermal documentation.

If your manufacturer has a specific report format or documentation checklist, contact us before the survey. We will confirm that our deliverables meet their criteria. We have experience working with commercial roofing manufacturer warranty programs and can coordinate directly with your manufacturer representative if needed.

Trust the Process

Step 1 — Pre-survey coordination

We confirm roof dimensions, access requirements, scheduling window, and any manufacturer-specific documentation requirements before mobilization.

Step 2 — Nighttime infrared drone survey

Conducted after sunset when thermal contrast between wet and dry insulation is greatest. We survey the entire roof and produce a full thermal mosaic of the assembly.

Step 3 — Probe verification

Probe testing at flagged areas provides the quantitative moisture content readings. All penetrations are patched before we leave the site.

Step 3.5 — Optional Impedance Mapping

A surface-level scan maps moisture areas that were identified through previous thermography and probe verification. Inspectors mark areas on the roof where insulation is reading as wet to make it clear where removal or remediation needs to take place.

Step 4 — Report and documentation delivery

We deliver the complete written report, roof map, thermal imagery, and any supporting data within the agreed turnaround window.

Planning a restoration or overlay project?

Contact us with the project address, estimated roof size, and the system type. We will examine the roof system via satellite imagery prior to sending a proposal to ensure that the roof is a viable candidate for a moisture survey.
