Commercial and Industrial Roof Coatings for Professional Roof Coaters
Article 24 of 25
A successful roof-coating project requires more than good application.
The contractor must understand exactly what has been specified, submit
the required technical information, document changes, satisfy warranty
conditions, and produce a defensible project record.
The Written Requirements Define the Project
The contract documents establish what the contractor has agreed to
provide. A verbal conversation, sales brochure, familiar product name,
or previous project should not be substituted for the written
requirements of the current project.
Before bidding or beginning work, the contractor should identify every
document that affects the roof-coating system.
- Drawings and roof plans
- Technical specifications
- Scope-of-work documents
- Addenda and bid clarifications
- Manufacturer system specifications
- Approved submittals and substitutions
- Preconstruction meeting minutes
- Requests for information and written responses
- Change orders and field directives
- Building-code and approval requirements
- Warranty requirements
- Owner standards and facility restrictions
Contractor principle: If an important requirement is
unclear, obtain written clarification before pricing, purchasing
material, or applying the roof system.
Common Types of Specifications
| Specification Type |
What It Does |
Contractor Concern |
| Prescriptive specification |
Identifies the required materials, preparation,
application steps, reinforcement, coverage rates,
thicknesses, and details.
|
Follow the stated system. Do not assume that a different
product or application method is equivalent.
|
| Performance specification |
Defines required outcomes or performance properties while
allowing some flexibility in system selection.
|
Confirm how compliance will be demonstrated and who is
responsible for system design.
|
| Proprietary specification |
Names a particular manufacturer, system, or product.
|
Determine whether substitutions are prohibited, permitted
before bid, or subject to formal approval.
|
| Reference-standard specification |
Incorporates ASTM, ANSI, FM, UL, NRCA, CRRC, building-code,
or other published requirements.
|
Verify the required edition and understand which portions
apply to the work.
|
| Manufacturer specification |
Defines one manufacturer’s approved assembly, products,
preparation, details, and application requirements.
|
Obtain the current project-specific version and confirm
that it supports the requested warranty.
|
Many projects combine these approaches. For example, a specification may
name an approved manufacturer while also requiring minimum physical
properties, tested assemblies, reflectance values, application rates,
and a particular warranty.
Reading the Roof-Coating Specification
A coating contractor should extract the requirements into a working
checklist. Important information is often distributed across multiple
specification sections, drawings, notes, schedules, and detail sheets.
System Requirements
- Existing roof and substrate type
- Approved manufacturer and system
- Primer and pretreatment
- Base coat and finish coat
- Reinforcement type and width
- Detail materials
- Coating color
- Coverage rate and minimum thickness
- Number of coats
- Required application method
Project Requirements
- Substrate repairs and replacement
- Moisture investigation
- Drainage correction
- Adhesion testing
- Environmental limitations
- Inspection and testing
- Manufacturer site visits
- Protection of occupied areas
- Warranty duration and type
- Closeout documentation
Do not select isolated numbers: A published coverage
rate, dry-film thickness, elongation value, or tensile strength does not
describe an entire roof system. Requirements must be read in the context
of the specified substrate, preparation, primer, reinforcement, number
of coats, and warranty.
Division 07 and Fluid-Applied Roofing
Commercial roofing requirements are commonly located within Division 07,
Thermal and Moisture Protection. Fluid-applied roofing may be addressed
in CSI MasterFormat Section 07 56 00, but project organization and section
numbering can vary.
Related requirements may also appear in sections covering insulation,
sheet-metal flashing, roof accessories, joint sealants, vapor retarders,
spray polyurethane foam, roof restoration, demolition, and temporary
protection.
The contractor should read the complete project manual and drawings
rather than relying on one section title.
Product Data versus System Documentation
A product data sheet describes an individual material. A system
specification explains how multiple products are assembled into a
functioning roof system.
| Document |
Typical Information |
What It Does Not Prove by Itself |
| Technical data sheet |
Product properties, coverage, application limitations,
cure, packaging, and storage.
|
That the product is approved for the specific roof,
substrate, or warranty.
|
| Safety data sheet |
Hazards, exposure controls, PPE, handling, first aid,
storage, and emergency information.
|
System performance or suitability for the project.
|
| System specification |
Preparation, primer, repairs, reinforcement, application
rates, sequencing, and details.
|
That all project-specific conditions have been evaluated.
|
| Evaluation or approval report |
Tested configuration, recognized uses, limitations, and
installation conditions.
|
Approval of configurations not included in the report.
|
| Warranty sample |
General coverage, exclusions, owner obligations, and
remedies.
|
That the completed project has been accepted for warranty.
|
The Submittal Package
Submittals allow the owner, consultant, design professional, and
manufacturer to review what the contractor proposes to install. The
package should be project-specific, organized, and submitted early
enough to permit proper review.
Recommended Roof-Coating Submittals
- Manufacturer’s project-specific system specification
- Technical data sheets for every proposed product
- Current safety data sheets
- Color and finish information
- Primer-selection documentation
- Reinforcement descriptions and dimensions
- Detail drawings for seams, penetrations, curbs, drains, and edges
- Required ASTM compliance documentation
- Applicable code, FM, UL, or evaluation reports
- CRRC product information when cool-roof properties are required
- VOC documentation when required
- Installer authorization or qualification
- Project references or experience documentation
- Sample warranty and warranty requirements
- Inspection and quality-control plan
- Adhesion-test or mockup procedure
- Product storage and handling requirements
- Proposed repair procedures for the existing roof
Approval is not a blank check: Approval of a submittal
generally does not relieve the contractor from complying with the
contract documents, verifying field dimensions, coordinating the work,
or identifying deviations.
Substitutions Must Be Evaluated as Complete Systems
A proposed substitute should not be accepted merely because it uses the
same general chemistry. Two acrylic, silicone, polyurethane, or
polyurea products may have different primers, solids content, cure
requirements, tensile properties, elongation, permeability, adhesion,
weathering performance, approvals, and warranty conditions.
A responsible substitution request should identify:
- The exact product and complete proposed system
- The specified product or system being replaced
- All differences from the contract requirements
- Required primers, details, reinforcement, and application rates
- Compatibility with the existing roof substrate
- Physical-property comparisons using equivalent test methods
- Code, fire, wind, and cool-roof approvals when applicable
- Warranty availability and changes in warranty coverage
- Cost or schedule effects
- Written manufacturer acceptance for the intended application
Substitutions should be approved in writing by the authorized project
party before materials are ordered or installed.
Requests for Information and Change Control
An RFI is used when the contract documents contain an ambiguity, conflict,
omission, or condition requiring clarification. It should describe the
issue objectively and identify the affected location.
An RFI response does not automatically authorize additional cost, time,
or a change in scope. When the answer changes the contracted work, the
contractor should follow the project’s written change-order procedure.
Conditions Requiring Clarification
- Unidentified roof substrate
- Unexpected wet insulation
- Incompatible existing coating
- Unspecified primer
- Conflicting coverage requirements
- Missing detail at a penetration
- Unacceptable drainage condition
- Unknown previous repair material
Record the Resolution
- RFI number and date
- Exact roof location
- Photographs or marked drawings
- Applicable specification reference
- Written response
- Cost and schedule effect
- Approved change document
- Final as-built condition
Warranty Language Must Be Read Before Bidding
The word warranty can describe very different levels of
coverage. Contractors should never promise a “20-year roof warranty”
without identifying who issues it, what it covers, what it excludes,
and what conditions must be satisfied.
| Warranty Type |
Typical Provider |
General Scope |
| Product or material warranty |
Manufacturer |
Generally addresses a defined defect in the manufactured
product. Labor, removal, access, repairs, and consequential
costs may be excluded.
|
| Contractor workmanship warranty |
Installing contractor |
Generally addresses installation defects for a stated
period under the contractor’s written terms.
|
| Manufacturer system warranty |
Roof-system manufacturer |
May cover defined system performance, materials, and
sometimes labor, subject to the exact warranty language.
|
| Labor-and-material warranty |
Manufacturer or contractor |
May include specified repair labor and material, but
exclusions, monetary limits, and owner responsibilities
still apply.
|
| NDL or no-dollar-limit warranty |
Manufacturer |
Commonly intended to avoid a stated monetary repair limit,
but coverage remains controlled by the warranty’s terms,
exclusions, and conditions.
|
Do not describe warranties from memory: Read the actual
sample warranty and project-specific requirements. Warranty terminology
is not identical among manufacturers.
Questions to Ask About the Warranty
- Who is the legal issuer of the warranty?
- When does the warranty period begin?
- What roof areas and components are covered?
- Are leaks covered, or only manufacturing defects?
- Are repair labor and materials included?
- Is there a dollar limitation, deductible, or service charge?
- Are consequential damages or interior damages excluded?
- Are ponding-water areas covered or excluded?
- Are wind, hail, fire, chemical exposure, or biological growth excluded?
- Are leaks from equipment, walls, windows, or penetrations excluded?
- Are unauthorized repairs grounds for cancellation?
- What owner inspections and maintenance are required?
- How quickly must a leak or damage be reported?
- Must repairs be performed by an approved contractor?
- Is the warranty transferable to a new building owner?
- Does transfer require notice, inspection, or payment?
Conditions Required for a Manufacturer Warranty
Requirements vary by manufacturer, system, roof condition, building,
location, warranty length, and exposure. Common requirements may include:
- Use of a manufacturer-authorized or approved contractor
- Preconstruction roof survey or manufacturer review
- Moisture investigation and removal of wet materials
- Approved adhesion testing
- Project registration before work begins
- Use of a complete approved system
- Specified application rates and minimum thickness
- Approved details and reinforcement
- Documented material quantities and batch numbers
- Manufacturer inspections or progress photographs
- Correction of punch-list items
- Submission of final invoices, reports, and warranty fees
- Owner acceptance of maintenance obligations
The contractor should obtain written confirmation that the proposed
system and project conditions qualify for the requested warranty before
making commitments to the owner.
Building-Code, Fire, and Wind Requirements
The project may require evidence that a roof assembly satisfies specific
building-code, fire-classification, uplift, or severe-weather
requirements. Compliance belongs to the tested or evaluated assembly—not
simply to a bucket of coating.
Verify that the approval applies to the actual combination of:
- Structural roof deck
- Vapor retarder or air barrier
- Insulation type and attachment
- Cover board
- Existing or new roof membrane
- Primer, foam, reinforcement, and coating
- Attachment pattern
- Roof-zone and perimeter requirements
- Building height and location
- Required wind-uplift pressure
System approval is configuration-specific: A listed
product may be part of an approved assembly, but that does not mean every
assembly using that product carries the same approval.
Cool-Roof Requirements
When the project requires specific solar reflectance or thermal emittance,
verify the exact product, color, tested values, aging status, and
applicable code or program requirement.
The
Cool Roof Rating Council Roof Rating Program
publishes rated surface radiative properties for roofing products.
CRRC ratings report product values; they do not by themselves declare
that a product satisfies every energy code, project specification, or
incentive program.
The contractor should verify the product in the current CRRC Rated Roof
Products Directory and confirm whether the project requires initial,
rapid-rated, or three-year-aged values.
Daily Project Documentation
Daily documentation establishes what happened during construction.
Reports should be completed while the information is current and should
identify specific roof locations.
Recommended Daily Report Information
- Date, project name, and report number
- Personnel and hours worked
- Roof areas worked on
- Weather and environmental readings
- Substrate condition
- Preparation and repairs completed
- Products and batch numbers used
- Containers opened, installed, wasted, and remaining
- Mixing and application equipment
- Coverage and wet-film measurements
- Start, stop, and cure times
- Adhesion, moisture, or other tests performed
- Photographs tied to roof locations
- Visitors and manufacturer inspections
- Delays, interruptions, and unexpected conditions
- Instructions received and corrective work completed
Photographic Documentation
Photographs should tell the story of the work, not merely show that
someone was on the roof. Use consistent roof-area names and photograph
important work before it is covered.
- Overall roof condition before work
- Moisture-damaged and deteriorated areas
- Existing seams, fasteners, penetrations, drains, and flashings
- Cleaning and preparation
- Completed substrate repairs
- Primer application
- Reinforcement placement and embedment
- Wet-film measurements
- Material labels and batch numbers
- Daily stopping points
- Defects and their repair boundaries
- Completed repairs
- Finished roof and drainage components
Photograph files should be named or indexed so another person can
identify the date, roof area, direction of view, and subject years later.
Closeout Documentation
Project closeout should be planned before mobilization. Waiting until the
end of the project to discover missing records can delay payment,
acceptance, and warranty issuance.
Technical Closeout
- Final inspection report
- Completed punch list
- Material-usage summary
- Batch and lot records
- Thickness and adhesion results
- Repair records
- Final roof photographs
- As-built roof-area map
- Approved changes and RFIs
Owner and Warranty Closeout
- Manufacturer warranty
- Contractor workmanship warranty
- Maintenance instructions
- Inspection schedule
- Approved repair procedures
- Product data and safety data sheets
- Emergency contact information
- Warranty claim procedure
- Transfer requirements
Common Documentation Failures
| Documentation Failure |
Possible Consequence |
Better Practice |
| Using an outdated technical data sheet |
Incorrect coverage, cure, primer, or application
requirements.
|
Date-stamp and retain the current document used for the
project.
|
| Depending on verbal approval |
Disagreement about responsibility, scope, cost, or
accepted repair.
|
Obtain written authorization from the designated project
authority.
|
| Recording weather only once per day |
Missed temperature, humidity, dew-point, wind, or rain
changes.
|
Record conditions at required intervals and when
conditions change.
|
| Photographs without locations |
Images cannot be tied to a specific roof area or repair.
|
Use marked roof plans, file names, captions, and direction
references.
|
| Tracking purchases instead of installed material |
Material delivered elsewhere, returned, wasted, or left
unused may be counted incorrectly.
|
Reconcile actual containers against mapped application
areas.
|
| Waiting until project completion |
Missing batch numbers, readings, photographs, and
approvals cannot be reconstructed reliably.
|
Review documentation daily and maintain a running
closeout file.
|
Build a Defensible Project Record
A strong project record should allow a knowledgeable person who was not
present during construction to understand:
- What roof conditions existed before work began
- What system was approved
- What materials were delivered and installed
- How the substrate was prepared
- How seams, details, and repairs were completed
- What environmental conditions existed during application
- What quantities and thicknesses were applied
- What testing was performed
- What problems occurred and how they were corrected
- Who inspected and accepted the completed work
Good documentation protects the owner, contractor, manufacturer,
consultant, and future maintenance personnel. It also provides valuable
information when the roof is inspected, repaired, modified, or renewed.
Technical References and Industry Resources
Standards and reference publications may require purchase or authorized
access. Verify the edition adopted by the project. Always use the
manufacturer’s current technical data sheets, safety data sheets,
system specifications, approval reports, details, and warranty
requirements.
Article 24 Takeaway
Specifications, approvals, submittals, warranties, and project records
are part of the installed roof system. They determine what must be
installed, how compliance will be judged, and what protection the owner
will receive after completion.
The professional roof coater reads the documents before bidding,
identifies conflicts before application, records conditions every day,
obtains written approval for changes, and completes the warranty and
closeout requirements before leaving the project.
