Building Envelope & Moisture Diagnostics
When Moisture Hides, Damage Grows
You can’t fix what you can’t see.
Trapped moisture moves silently through insulation, sheathing, and wall assemblies—degrading performance long before visible damage appears. A small leak today becomes microbial growth, corrosion, or insulation collapse tomorrow.
At Roofing Analysis & Consulting (RAC), we don’t guess where water goes—we trace it.
Our Building Envelope & Moisture Diagnostics service uses the RoofingLogix™ Methodology to find the source, measure the extent, and document the mechanism of intrusion so you can restore performance with confidence.
The Problem: Hidden Moisture = Hidden Risk
Policyholders
see stains but not the path of water.
Contractors
replace membranes without knowing why they failed.
Carriers and attorneys
need proof of cause—not just a wet spot.
Unverified moisture data leads to premature replacement, recurring failures, and disputes over coverage or responsibility.
RAC’s RoofingLogix™ Diagnostics replace guesswork with measurable truth.
The RoofingLogix™ Methodology: Science Before Summary
Every diagnostic investigation follows RAC’s RoofingLogix™ protocol—integrating standards from ASTM, NRCA, SMACNA, ASHRAE, FM Global, IIBEC, and IICRC.
We combine thermal imaging, humidity data, pressure differentials, and material analysis to map where moisture enters, how it travels, and what it affects. By correlating real-time field data with building-physics principles, we reveal what others miss.
For policyholders and contractors, it means verified evidence that justifies scope and coverage.
For designers and insurers, it means defensible documentation that prevents future loss.
Our Process
Step 1 — Non-Destructive Detection
- Infrared thermography per ASTM C1153 and D7954
- Electrical impedance and capacitance scanning
- Psychrometric and dew-point measurements (ASHRAE 160 & 55)
- Air infiltration tests (ASTM E1186, E779)
Step 2 — Verification & Sampling
- Core sampling and gravimetric moisture content testing
- Material adhesion and fastener pull-out evaluation
- Vapor retarder and air barrier integrity checks (SMACNA & NRCA guidelines)
- Interior correlation per IICRC S500/S520 for drywall, insulation, and ceiling assemblies
Step 3 — Analysis & Correlation
- Cross-reference data to weather records and building pressurization profiles
- Determine primary vs. secondary moisture migration paths
- Quantify risk for mold, corrosion, and material failure
- Recommend mitigation or restoration per industry standards
Deliverables: A Clear Moisture Map
RAC diagnostic reports turn complex data into actionable clarity.
Every report includes:
- Infrared and moisture mapping with color-coded visuals
- Photographic and sampling logs
- Psychrometric analysis summary charts
- Recommendations with ASTM, NRCA, ASHRAE, and IICRC references
- Appendices for claim, design, or QA/QC documentation
