Research Methods & Evidence-Based Practice Flashcards

Which organization publishes the FM Global Property Loss Prevention Data Sheets that roofing contractors often reference for wind uplift resistance standards?

Answer: FM Global

FM Global publishes Property Loss Prevention Data Sheets that provide evidence-based standards for wind uplift resistance used in commercial roofing.

When reviewing a manufacturer's product data sheet, which section most directly informs a contractor about the tested performance limits of a roofing membrane?

Answer: Physical properties table

The physical properties table lists tested values such as tensile strength, elongation, and puncture resistance that define performance limits.

A contractor notices field performance of a product differs from lab test results in the manufacturer's data sheet. What is the most evidence-based first step?

Answer: Document conditions and consult the manufacturer's technical support

Documenting conditions and consulting the manufacturer's technical team allows root-cause analysis comparing controlled lab conditions to real-world variables.

What does the term 'third-party tested' mean when referenced on a GAF product specification sheet?

Answer: An independent laboratory verified the product's performance claims

Third-party testing means an independent, accredited laboratory validated the manufacturer's performance claims, adding credibility to the data.

Which roofing research concept describes the systematic review of multiple studies to reach a stronger overall conclusion than any single study provides?

Answer: Meta-analysis

A meta-analysis combines results from multiple studies statistically, producing more reliable conclusions than any individual study alone.

GAF's roofing system warranties require that products are installed according to the manufacturer's application instructions. Why is this considered an evidence-based requirement?

Answer: Installation methods were validated through testing to achieve stated performance

Manufacturer application instructions are derived from testing protocols that confirmed specific installation methods produce the warranted performance outcomes.

What is the primary purpose of GAF's Certified Contractor program requiring continuing education on new research and products?

Answer: To ensure contractors apply current evidence-based best practices

Continuing education keeps certified contractors current with evolving research, materials science, and installation techniques that represent evidence-based best practices.
