Some detailed info on roofing forensics
A roofing forensics study is a specialized investigation that applies scientific principles to determine the cause of roofing and overall building envelope failures. The building envelope consists of all the components that separate a building’s interior from the exterior, including the roof, walls, windows, and foundation.
The goal of a forensic investigation is to identify the root cause of the problem, such as persistent leaks, premature system failure, or damage after a weather event. The findings are often used for legal disputes, warranty claims, or to design effective repair strategies.
Key aspects of the investigation
Forensic experts use a variety of tools and methodologies to perform a thorough investigation, including:
- Document review: Investigators analyze original architectural plans, construction documents, and maintenance records to understand how the building was constructed and maintained.
- Visual inspection: A thorough visual assessment of the interior and exterior of the building identifies signs of stress, damage, or water staining. Drones are often used to inspect hard-to-reach or hazardous areas, such as the roof.
- Infrared thermography: Thermal imaging cameras detect temperature variations that can indicate hidden moisture trapped inside the roof or walls.
- Moisture surveys: Specialized moisture meters are used to locate and confirm moisture within building materials
- Controlled testing: This involves standardized tests to pinpoint weaknesses in the building’s exterior. Common examples include ASTM E2128 and ASTM E1105 protocols for water penetration testing on walls and windows.
- Destructive testing: If necessary, engineers may conduct destructive testing, which involves making targeted openings in walls or roofs to inspect concealed components and confirm the extent of the damage.
- Material and laboratory analysis: Core samples of roofing materials may be taken for chemical and physical testing in a lab to check for material defects or premature degradation.
