Building Science Insights

Air movement drives condensation and roof decay. Discover how blower door and pressure diagnostics reveal hidden leakage patterns that traditional inspections miss.

Go behind the scenes of a typical RAC investigation. See how infrared, core sampling, and data modeling uncover root causes that even contractors and engineers often overlook.

“Cool roofs” are not always cooler. Learn what new research says about reflectivity, condensation risk, and how over-insulation can actually increase moisture loading in attics and roof decks.

Air, vapor, and thermal control layers must work together. This article breaks down how poor coordination between trades causes hidden failures and long-term structural decay.

Whether you represent a carrier or a policyholder, success in appraisal depends on facts, not assumptions. Here’s how RAC’s analytical approach to documentation changes outcomes for both sides.

Moisture intrusion is one of the most misunderstood failures in roofing. Learn how trapped vapor, improper fastener patterns, and air leakage cause recurring leaks — and how forensic testing identifies the real cause.
