Building Envelope & Moisture Diagnostics
Finding what’s really behind leaks, stains, and hidden damage.
When Moisture Hides, Damage Grows
When water appears inside a building, the cause isn’t always the roof. Moisture can travel through walls, ceilings, and mechanical openings — following air pressure and temperature changes that move it far from its source.
At Roofing Analysis & Consulting (RAC), we perform building-envelope and moisture diagnostics to identify how water, air, and heat move through a structure.
Our goal is simple: locate the true source of leaks and prevent further damage — not just treat the symptoms.
Most moisture problems start with unseen conditions — not visible leaks.
Our diagnostics reveal what’s truly happening beneath the surface, before repairs or claims are made.
What We Do
RAC examines the building as an integrated system — roof, walls, insulation, and ventilation all working together (or sometimes against each other).
Our diagnostic process includes:
- Infrared thermography and drone-based aerial imaging to locate hidden wet areas and insulation loss.
- Blower-door testing to measure air leakage and pressure imbalances.
- Moisture probing and mapping to determine the extent of saturation.
- Vapor-drive and dew-point analysis to assess condensation and humidity movement.
- Review of materials, ventilation, and mechanical design for moisture-migration risks.
- Detailed reporting with annotated imagery and corrective recommendations.
Whether it’s a flat commercial roof or a residential attic, we determine how water entered, how far it spread, and what must be done to restore the envelope’s integrity.
Why It Matters
Moisture is one of the most misunderstood forms of damage.
Leaks blamed on roofs may actually start in wall cavities, poorly sealed windows, or unbalanced HVAC systems.
Misdiagnosing the cause leads to wasted money, repeated failures, and sometimes mold or structural decay.
A moisture diagnostic matters because it:
- Pinpoints the actual entry point — not just the visible damage.
- Prevents unnecessary roof replacements when the issue is elsewhere.
- Documents hidden water intrusion for insurance or warranty claims.
- Protects indoor air quality by addressing unseen humidity and mold potential.
- Saves time, cost, and frustration by solving the root problem once.
The real danger isn’t water itself — it’s not knowing where it came from.
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.
Standards & Technology
RAC follows nationally recognized standards, including:
- ASTM E1186 / E2128 – Building Envelope Water-Intrusion Diagnostics
- IICRC S500 / S520 – Water Damage & Microbial Remediation
- ASHRAE 62.2 / 160 – Moisture Control and Indoor Air Quality
- NRCA Roofing & SMACNA Sheet Metal Manuals
- ICC / IRC / IBC Building Codes for air and moisture management
All instruments are calibrated, and results are fully verifiable and defensible.
How It Connects to Claims
Moisture diagnostics often clarify gray areas in insurance evaluations.
A minor leak can reveal hidden storm-related damage — or confirm an issue is unrelated to a claim.
Because RAC holds Adjuster and Public Adjuster licenses, we can legally interpret and communicate findings in the context of coverage.
Our reports separate storm-caused damage from age, defect, or installation error, ensuring all parties understand what falls under the covered peril — and what does not.

If you notice water stains, humidity issues, or other signs of water damage, don’t assume it’s the roof.
The best time to call is as soon as you notice a problem — or if you suspect a problem or storm damage but aren’t sure whether to file a claim.
RAC will determine whether the issue warrants a claim, or if it’s another matter entirely, saving you time, money, and frustration.
