Roof Moisture Surveys
Non-destructive surveys locate trapped moisture and wet insulation within the roof assembly. Every survey concludes with a detailed written report, findings, and a color graph outlining problem areas.

Services
Testing and consulting for commercial flat roofs.
A full range of non-destructive testing, forensic, and consulting services — each concluding with a written report of findings and recommendations, and a color moisture map where applicable.
Wind Uplift Testing
Field testing of a roof system’s resistance to wind uplift forces, which concentrate at perimeters and corners and can compromise the entire assembly.
ASTM E-907Fastener Uplift Testing
Withdrawal-resistance testing determines whether mechanical fasteners provide sufficient uplift resistance for the roof assembly and helps establish fastener-spacing requirements.
Withdrawal resistanceDe-saturation Testing
Evaluation of moisture-laden roof components to determine the degree of saturation and whether affected areas can be dried, repaired, or must be replaced.
Moisture assessmentProject Management
Independent oversight of roofing projects — from specification and scope through construction observation — protecting the owner’s interests at every phase.
Owner’s representativeForensic Roof Analysis
Investigative analysis to determine the cause, origin, and extent of roof failures and water intrusion, documented with objective test data.
Cause & originExpert Witness
Credentialed expert testimony and litigation support for insurance claims and construction disputes, grounded in laboratory testing and field evidence.

Uplift-resistance testing of adhered or mechanically attached roof assemblies to verify attachment of the total system to the deck.

The testing behind the report
- Wind Uplift TestingASTM E-907 · TAS 124-95
- Determines a roof assembly’s resistance to uplift pressure across the field of the roof, with corners and perimeters calculated separately.
- Fastener Uplift TestingWithdrawal resistance
- Confirms whether a given fastener provides sufficient static uplift resistance for the assembly, and informs fastener-spacing requirements.
- Roof Moisture SurveysNon-destructive
- Locate trapped moisture and wet insulation and map their extent, so only affected areas are addressed — not the entire roof.
- Bonded Pull TestSystem attachment
- Verifies attachment of an adhered or mechanically attached roof system to the deck.
