Specification Review, Design & QA Oversight
Precision-designed and independently verified roofing and envelope systems.
Design Is Intent — Performance Is Proof
A roof system can look flawless on paper yet fail in the field.
Specifications often conflict between drawings, manufacturer requirements, and installation realities — leaving contractors guessing and owners paying for redesigns or repairs later.
At Roofing Analysis & Consulting (RAC), we bridge that gap.
Our Specification Review, Design & QA Oversight service ensures that every detail — from submittal to system warranty — performs to design intent, code, and physics.
Because a line on paper isn’t protection until it’s proven in the field.
What We Do
RAC provides independent, data-driven design and quality oversight for architects, contractors, owners, and insurers.
Our services include:
- Design-Phase Specification & Detailing
- Create or review roof and envelope specifications for constructability, performance, and compliance.
- Produce 3D CAD and BIM-compatible roof and wall assemblies showing slopes, transitions, and penetrations.
- Integrate digital drainage models, wind-uplift calculations, and flashing details to meet code and manufacturer criteria.
- Digital Site Modeling & Verification
- Deploy LiDAR and photogrammetry scanning to map existing conditions, dimensions, and roof geometry.
- Generate accurate as-built models that eliminate measurement errors and rework.
- Use digital overlays to compare design intent vs. field conditions in real time.
- Submittal & Pre-Installation Review
- Evaluate drawings, submittals, and substitutions for compliance with the approved design.
- Confirm all components meet required wind, fire, and energy codes (IBC/IRC, FM, ASCE, ANSI/SPRI).
- Submittal & Pre-Installation Review
- Evaluate drawings, submittals, and substitutions for compliance with the approved design.
- Confirm all components meet required wind, fire, and energy codes (IBC/IRC, FM, ASCE, ANSI/SPRI).
- On-Site Quality Assurance Inspections
- Perform progress inspections at critical installation stages (deck prep, underlayment, flashings, seams).
- Use drone-based thermography and high-resolution imagery to verify field progress and detect anomalies.
- Provide photographic documentation and daily QA reports for traceability.
- Final Verification & Closeout
- Conduct core verification or moisture scans to confirm a dry-in condition.
- Document all terminations, flashings, and transitions for warranty and insurance purposes.
- Deliver comprehensive QA packages with 3D renderings, as-built data, and compliance reports.
Why It Matters
Most roof or envelope failures are preventable.
They don’t come from bad materials — they come from gaps between design, documentation, verification, and installation.
Without an integrated QA process:
- Design intent can be lost in translation between the architect and the contractors.
- Substitutions may void warranties or reduce performance.
- Missing data can lead to costly errors or denied claims later.
With RAC involved from the start:
- Designs are accurate, compliant, and field-ready.
- Construction stays on track with verifiable data.
- Owners, insurers, and manufacturers gain confidence that the system performs as specified.
Design it right. Verify it. Build it once. Build it right!
Our Design & QA Workflow
RAC combines digital precision with building-science expertise to eliminate guesswork and ensure measurable quality.
Digital Design Phase
- LiDAR and drone scanning to capture site data and surface geometry.
- Conversion to CAD/BIM models for design and drainage analysis.
- Integration of slope, wind, and load data for performance modeling.
- Clash detection for penetrations, parapets, and transitions.
Field QA Oversight
- Visual and instrumented inspection at key stages.
- IR and drone thermography for coverage verification.
- Adhesion, fastener, and pull-test sampling (ASTM D 7877 / FM 1-52).
- Comparison of installed work vs. digital model for dimensional accuracy.
Documentation & Delivery
- Final QA package with annotated photos, 3D visuals, and compliance matrix.
- Includes manufacturer, code, and warranty verification checklist.
Permanent digital record for warranty submission or insurance audit
How It Connects to Claims & Warranty Compliance
RAC’s QA and design documentation provides objective proof that assemblies meet all required standards.
That documentation:
- Protects owners and contractors from future disputes.
- Confirms code and warranty compliance for insurers and manufacturers.
- Provides measurable baseline data for any future inspections or storm claims.
In cases of later damage, our 3D and LiDAR-based as-built records often become the decisive evidence in determining whether failure resulted from design, workmanship, or a covered peril.
Standards & Technology
RAC’s specification and QA systems are built around the following standards and protocols:
- NRCA Roofing Manuals (Steep & Low-Slope)
- FM Global 1-28 / 1-29 / 1-52 (Wind & Attachment Requirements)
- ANSI/SPRI ES-1 (Edge Metal Testing)
- ASTM D 7877 / D 7905 / E 2128 (Roof QA & Water Intrusion)
- ASCE 7-16 / 7-22 (Wind Load Calculations)
- ICC IBC/IRC (2018–2021 Editions)
- Manufacturer Warranty Protocols (Carlisle, GAF, Sika, Johns Manville, etc.)
We combine field-tested standards with cutting-edge scanning and CAD platforms to deliver results that are both practical and defensible.
Who We Support
Architects & Engineers
seeking design validation before bid or warranty.
Contractors
needing QA oversight that prevents callbacks and protects installation integrity.
Owners & Policyholders
wanting assurance that the system they paid for performs to specification.
When RAC is involved, every stakeholder gains confidence — and every system gain accountability.
Build it once — and build it right.
Whether you need specification review, 3D design, or independent QA oversight, RAC delivers precise documentation and verifiable quality that protects your investment in the long term.
Because a roof’s strength begins long before the first fastener is driven.
