Why Systems Fail
Forensic analysis of failure causes in commercial roof coatings, waterproofing membranes and liquid systems. Understanding why failure occurs determines what the specification must prevent.
Why Roof Overlays Fail
Substrate moisture, preparation failures, drainage, detailing compatibility — why most overlay failures are specification failures, not product failures.
Why Liquid Coatings Delaminate
Adhesion breakdown — the role of primer, contamination, trapped moisture and substrate movement in delamination failure.
Why Trapped Moisture Destroys Overlays
Vapour pressure, blistering and substrate degradation — why moisture testing is mandatory before any overlay specification.
Why Detailing Determines Roof Lifespan
Penetrations, parapets, gutters and upstands are where roofs fail. Detailing scope determines service life, not the field membrane.
Why Gutters Repeatedly Fail
Joint failure, inadequate falls and temporary repair cycles — why patch repair without addressing root cause produces repeat failures within 18 months.
Why Standing Water Matters
Drainage failure and its consequences for overlay specification — why ponding water is not cosmetic.
Why Metal Roof Coatings Fail Prematurely
Thermal movement, fixing-line corrosion and inadequate elongation — why standard coatings crack on profiled metal roofing.
Why Traffic Destroys Non-Traffic-Rated Systems
Vehicle loading, polyurea specification and why car park decks require traffic-rated systems — not roof coatings.
Why Preparation Failures Invalidate Warranties
Moisture, primer omission, contamination and compressed preparation time — the dominant warranty rejection factors.
Why Overlay Cannot Fix Structural Failure
Structural assessment thresholds before any coating system — when overlay must stop and structural remediation begin.
