How ROOFNOW™ Evaluates Roofing Systems
ROOFNOW™ evaluates roofing systems using a structured, methodology-driven approach rooted in building science, climate data, and long-term performance analysis. This methodology is designed to ensure that educational content remains independent of manufacturers, installers, and product sales pathways.
This page outlines the principles and evaluation criteria used across ROOFNOW™ educational content.
Purpose of the ROOFNOW™ Methodology
The purpose of the ROOFNOW™ methodology is to explain how roofing systems behave over time, rather than to recommend specific products or contractors. Evaluation focuses on performance mechanisms, environmental interaction, and long-term durability under real-world conditions.
Core Evaluation Principles
- Independence: No evaluation criteria are tied to manufacturer incentives, certifications, or dealer programs.
- Climate Specificity: Performance is analyzed within regional climate conditions, including snow load, freeze-thaw cycles, wind exposure, and solar gain.
- Lifecycle Focus: Systems are evaluated over 20–50 year horizons rather than warranty periods.
- Building Science First: Physical mechanisms are prioritized over marketing claims.
- Transparency: Assumptions, limitations, and trade-offs are clearly stated.
Key Performance Factors Evaluated
Structural Load Behavior
Evaluation includes how roofing systems handle dead load, live load, snow accumulation, wind uplift, and structural stress over time.
Moisture Management
Systems are analyzed for condensation risk, vapor movement, water intrusion pathways, and drying potential.
Thermal Performance
Thermal expansion, contraction, heat transfer, and attic interaction are assessed using building physics principles.
Material Degradation
ROOFNOW™ evaluates how materials age due to UV exposure, temperature cycling, moisture, and mechanical fatigue.
Maintenance & Failure Modes
Common failure points, maintenance requirements, and repairability are considered as part of long-term performance.
Lifecycle Cost Modeling
Rather than focusing on upfront installation cost, ROOFNOW™ considers:
- Expected service life
- Maintenance frequency
- Repair likelihood
- Replacement cycles
- Total cost over the life of the home
What ROOFNOW™ Does Not Do
- Provide contractor recommendations within educational content
- Rank or score manufacturers for promotional purposes
- Offer product endorsements tied to compensation
- Blend education with sales funnels
Relationship to Roofing Advice
The ROOFNOW™ methodology is designed to precede roofing advice. By establishing foundational knowledge first, homeowners are better equipped to evaluate recommendations provided by contractors, manufacturers, or advisors.
Why This Methodology Matters
A transparent evaluation methodology helps homeowners:
- Understand why systems perform differently
- Recognize marketing claims versus physical reality
- Make informed long-term decisions
- Avoid repeat re-roofing driven by incomplete information
