Roof Restoration & Coating Systems
Repair, preparation and liquid-applied roof systems for qualifying commercial, multifamily, metal, SPF and residential low-slope roofs throughout Palm Beach and Broward Counties.
What is roof restoration?
Roof restoration is a controlled repair, preparation and liquid-applied system installed over an eligible existing roof to renew its weathering surface and waterproofing performance without automatically removing the entire roof assembly.
Repair, Restore, Recover or Replace?
The least expensive initial option is not automatically the lowest-risk lifecycle decision. Start with the condition of the complete assembly.
Localized Repair
Correct one or more isolated defects when the surrounding roof remains serviceable.
- Leak entry point can be identified.
- Surrounding membrane remains repairable.
- No broad renewal is needed.
Roof Restoration
Repair and renew an eligible existing roof with a specified liquid-applied system.
- Substantially dry and adequately attached.
- Compatible substrate and repairable details.
- Drainage and flashing heights remain workable.
Approved Recovery
Install a new approved roof assembly over an eligible existing roof.
- May include insulation, cover board and new membrane.
- Added load, fire, moisture and attachment must be verified.
- Not the same as applying a coating.
Complete Replacement
Remove the existing roof as required and rebuild the coordinated assembly.
- Widespread moisture or deterioration.
- Deck, structure, attachment or drainage concerns.
- Existing roof is not a dependable substrate.

Seven Conditions Should Be Verified Before a Coating System Is Selected
A coating chemistry should not be selected until the existing roof is proven capable of supporting the restoration strategy.
A stronger restoration candidate is more than a roof that looks dry.
- Known and compatible roof substrate.
- Substantially dry insulation and deck.
- Adequate roof and perimeter attachment.
- Repairable seams, fasteners, flashings and penetrations.
- Serviceable drainage and overflow.
- Successful cleaning, primer and adhesion testing.
- Enough remaining system integrity to justify restoration.
Choose the System After the Substrate and Conditions Are Known
Each chemistry has different cure, weather, primer, ponding, reinforcement, dirt-pickup and recoat boundaries.
Ten Steps Should Happen Before the Final Topcoat Is Accepted
Many coating failures are preparation or specification failures—not simply chemistry failures.
Records and Survey
Identify roof type, layers, age, repairs, leaks, warranties and prior coatings.
Moisture Investigation
Use appropriate scans, cores and field verification to locate wet materials.
Clean and Dry
Remove dirt, biological growth, oils, loose surfacing and incompatible residue.
Remove Wet Materials
Replace wet insulation, damaged cover board and deteriorated deck as required.
Repair the Existing Roof
Correct seams, laps, fasteners, blisters, splits, penetrations and membrane defects.
Correct Details
Repair walls, curbs, drains, scuppers, flashings, perimeter and rooftop equipment interfaces.
Prime and Test Adhesion
Use the required primer and document representative adhesion tests.
Reinforce as Specified
Embed fabric, scrim or detail membrane at seams, transitions and repairs where required.
Apply Specified Coats
Control weather, mixing, coverage, wet-film thickness, cure and recoat windows.
Verify and Close Out
Inspect dry-film thickness, repairs, drains, touchups, documentation and warranty records.
The Existing Roof Determines the Preparation and Primer Path
This matrix is conceptual. Exact manufacturer technical data and field adhesion testing control.
| Existing roof | Potential restoration direction | Typical investigation / preparation | Major disqualifiers or limits |
|---|---|---|---|
| Smooth BUR / Modified Bitumen | Silicone, acrylic, reinforced liquid or asphaltic restoration | Moisture survey, cleaning, repairs, bleed-blocking primer or asphalt emulsion where specified | Wet insulation, unstable surfacing, coal tar, severe alligatoring or insufficient flashing height |
| Granulated Modified Bitumen | Silicone, acrylic or reinforced system after product-specific preparation | Remove loose granules, level rough areas, prime and test adhesion | Loose cap sheet, widespread splits, wet insulation or excessive surface texture without approved leveling |
| Aged TPO / PVC / KEE | Product-specific silicone, acrylic or reinforced liquid-applied system | Membrane identification, cleaning, repairs, primer and adhesion patches | Incompatible membrane, plasticizer migration, widespread shrinkage, poor attachment or active moisture |
| EPDM | Product-specific coating system with approved primer | Repairs, cleaning, treatment of seams, primer and adhesion testing | Unresolved shrinkage, contaminated surface, poor attachment or incompatible primer |
| Metal Roof | Silicone, acrylic, urethane or reinforced metal-restoration system | Corrosion treatment, panel replacement, seam and fastener repair, primer and movement review | Structural corrosion, failed panels/purlins, incompatible metals or unresolved condensation |
| SPF | Acrylic, silicone or approved SPF renewal system | Identify foam condition, remove damaged foam, repair bird pecks, moisture and UV deterioration | Widespread saturated foam, poor adhesion, extensive substrate failure or incompatible prior coating |
| Concrete | Approved liquid-applied waterproofing or restoration system | Crack repair, moisture/vapor review, cleaning, profile and primer | Hydrostatic pressure, structural cracking, contaminated concrete or incompatible curing compounds |
| Previously Coated Roof | Compatible recoat after identification and testing | Identify chemistry and history, clean, repair, abrade or prime as required, test adhesion | Unknown multiple coatings, chalking, delamination, trapped moisture or incompatible chemistry |
The System Must Be Measured—Not Judged by How White It Looks
Coverage and Dry-Film Worksheet
Conceptual calculation only. The manufacturer specification, surface texture, waste, reinforcement and field measurement control.
One gallon spread over 100 square feet is approximately 16 wet mils. Rough or porous surfaces can consume more material than a smooth theoretical calculation.
A coating does not create structural slope.
Before restoration, evaluate drains, scuppers, gutters, overflows, deck deflection, low areas, curbs and flashing heights.
- Some products have ponding-water resistance; others require positive drainage.
- Blocked outlets and localized defects may be repairable.
- Structural deflection and chronic ponding may require a different scope.
- Drainage limits should appear in the written specification and warranty documents.
Restoration Does Not Automatically Upgrade the Roof Below It
The existing roof must remain adequately attached for the property’s conditions. Coating the surface does not correct every wind, structural or envelope weakness.
Existing Attachment
Deck attachment, insulation attachment, membrane attachment and fastener withdrawal may require verification. A surface coating cannot make a poorly attached assembly dependable.
Perimeter and Edge Metal
Edges, coping, fascia, gutters and counterflashing may require repair or replacement. A liquid system should terminate into a stable, compatible and wind-resistant perimeter.
Roof-to-Wall and Envelope
Roof-to-wall connections, exterior walls, openings and other building-envelope features remain separate from coating restoration. Use the Wind & Code Guide for those decisions.
Open Wind & Code GuideA Reflective Roof Can Reduce Surface Temperature—But It Is Not Insulation
Reflective coatings can reduce solar absorption and roof-surface temperature. Building energy performance still depends on insulation, air leakage, HVAC, interior loads, roof area, reflectance retention, dirt pickup and maintenance. No specific utility savings should be promised without analysis.
Initial Reflectance
White and light-colored coatings can start with strong solar reflectance, but the exact rating is product-specific.
Reflectance Retention
Dirt, biological growth, weathering and maintenance influence how the surface performs over time.
Complete Assembly
Insulation, air sealing, ventilation, vapor control, deck type and HVAC conditions remain major performance variables.

Roof Restoration Questions Property Owners Should Ask
What is roof restoration?
Roof restoration is a specified repair, preparation and liquid-applied system installed over an eligible existing roof to renew its weathering surface and waterproofing performance without automatically removing the entire roof assembly. It is not simply paint and it is not appropriate for every roof.
How is restoration different from a repair?
A repair corrects one or more localized defects. Restoration addresses the existing roof more broadly through repairs, cleaning, primers, reinforcement and a specified coating or liquid-applied membrane. A roof may need repairs before it can qualify for restoration.
How is restoration different from a roof recovery?
Restoration generally renews the existing roof with a liquid-applied system. Recovery installs an approved new roof assembly over an eligible existing roof. Recovery can add insulation, cover board, attachment and a new membrane; restoration usually relies more heavily on the existing assembly remaining serviceable.
Can a wet roof be coated?
Widespread or unresolved wet insulation should not be concealed beneath a restoration system. Moisture investigation, core cuts and selective removal may be required. Limited wet areas may sometimes be removed and replaced before restoration, subject to the manufacturer and project design.
Does a coating fix poor roof attachment?
No. A coating does not automatically improve the existing deck attachment, insulation attachment, membrane attachment, roof-to-wall connection or perimeter resistance. Those conditions must be investigated and corrected separately when required.
Can ponding water be coated over?
The answer is product- and condition-specific. Some silicone products are formulated to resist ponding water, while many acrylic systems require positive drainage. A coating does not correct structural deflection, blocked outlets or an inadequate drainage layout.
What is the difference between silicone and acrylic roof coatings?
Silicone and acrylic systems differ in chemistry, cure, weather window, dirt pickup, reflectivity, ponding-water limitations, recoat procedures and compatible primers. The exact product data and approved specification control; neither chemistry is universally superior for every roof.
Can TPO, PVC, KEE or EPDM be restored?
Some aged single-ply roofs may be eligible for manufacturer-approved restoration after cleaning, repairs, adhesion testing and any required primer. Compatibility varies by membrane and product. A coating should not be selected from the membrane acronym alone.
Can a metal roof be restored?
Potentially. Metal restoration normally requires corrosion review, panel and fastener repair, seam and penetration reinforcement, compatible primers, movement accommodation and coating at the specified thickness. Coating does not repair structurally failed or severely corroded panels.
Can asphalt shingles be coated?
Most commercial roof-coating systems are not intended for asphalt shingles, and several manufacturers expressly prohibit shingle application. Shingle restoration claims must be treated cautiously and verified against the exact product, code, manufacturer and warranty requirements.
Why do adhesion tests matter?
Adhesion patches help determine whether the selected primer and coating bond adequately to the cleaned and prepared substrate. One successful test does not replace full preparation or field quality control, but proceeding without testing can create avoidable delamination risk.
How is coating thickness verified?
The specification should identify application rate, wet-film thickness, volume solids, target dry-film thickness and the method of field verification. Color alone does not prove that the required membrane thickness was installed.
Can a reflective coating reduce energy costs?
A reflective surface may reduce roof-surface temperature and solar heat gain. Actual utility savings depend on insulation, air leakage, HVAC, internal loads, roof area, color, reflectance retention and maintenance. No specific savings should be guaranteed without a separate energy analysis.
What warranty options are available?
Warranty eligibility depends on the existing roof, repairs, approved system, application rate, dry-film thickness, contractor status, project registration, inspections, maintenance and written manufacturer terms. A warranty term is not a prediction of roof life.
What should a roof-restoration proposal include?
It should identify the existing roof, moisture and adhesion testing, cleaning, repairs, wet-area replacement, primers, reinforcement, exact products, coverage rates, target dry-film thickness, drainage limits, perimeter details, exclusions, quality control, warranty pathway and maintenance obligations.
When is replacement the better decision?
Replacement is generally the stronger pathway when moisture is widespread, the deck or structure is deteriorated, attachment is inadequate, drainage cannot be reasonably corrected, flashing heights are insufficient, multiple incompatible coatings exist or the existing roof no longer provides a dependable restoration substrate.
