Silicone roof coating for long-term protection.

Restore aging commercial roofs with a high-performance silicone system built to resist UV, standing water, and extreme heat.

ROC #362145

Silicone Roof Coating

Extend roof life without a full tear-off.

Silicone coating systems deliver durable waterproofing and reflectivity for commercial roofs. We combine moisture scanning, targeted repairs, and manufacturer-approved application for long-term performance.

Best For

A strong fit for these roof types.

Low-slope commercial roofs
Roofs with ponding water concerns
Aging membranes needing restoration
Facilities seeking energy savings

Benefits

Why silicone coatings perform so well.

Outstanding UV resistance

Silicone coatings maintain reflectivity and performance in harsh Arizona sun.

Ponding water protection

Ideal for low-slope roofs where standing water is a concern.

Seamless waterproofing

A continuous membrane reduces leak risk and seals penetrations.

Energy efficiency

Cool roof coatings can support lower HVAC costs during peak months.

Compatibility

Where silicone coatings make the most sense.

Compatible substrates

  • TPO, PVC, and EPDM (with proper primers)
  • Modified bitumen (SBS/APP)
  • Built-up roofing (BUR)
  • Spray polyurethane foam (SPF)
  • Metal roofs with appropriate prep
  • Concrete roof decks

Not ideal for

  • Widespread saturated insulation or trapped moisture
  • Severe substrate instability requiring tear-off
  • Heavily contaminated surfaces without viable cleaning
  • Details that can’t be corrected (drainage, flashings, terminations)

System Options

A system matched to your roof conditions.

Silicone restoration (standard)

A balanced system for many low-slope roofs: targeted repairs, seam reinforcement where needed, then silicone applied to specification.

Reinforced detail package

Fabric reinforcement at seams, penetrations, and transitions to strengthen leak-prone areas before the field coat.

High-traffic / walkway areas

Adds walk pads or enhanced protection around HVAC access points and service routes to reduce wear.

Technical Specs

Performance details at a glance.

Dry film thickness

Typically 20–35 mils, depending on system

Ponding water resistance

Designed for long-term waterproofing in standing water

UV durability

Excellent resistance for Arizona sun exposure

Adhesion

Primers selected per substrate chemistry

VOC compliance

Meets regional environmental requirements

Values are typical ranges; exact specifications are confirmed per project conditions and manufacturer requirements.

Our Process

Clear steps from inspection to closeout.

Step 1

Inspection & moisture scan

We assess membrane condition, locate wet insulation, and define the scope.

Step 2

Prep & repairs

Seam reinforcement, flashings, and repairs are completed before coating.

Step 3

Coating application

We apply the silicone system to manufacturer specs for thickness and cure.

Step 4

Final walk-through

We confirm workmanship and provide warranty-ready closeout details.

Maintenance Packages Available

Keep your coating performing long-term.

Seasonal inspections

Spring and fall roof walks to spot punctures, open seams, and clogged drains.

Drainage checks

Keep scuppers, drains, and gutters clear to prevent backups and interior leaks.

Detail touch-ups

Maintain flashings and high-stress transitions to protect the system long-term.

Warranty readiness

We outline recoat timing and maintenance priorities to keep warranty requirements on track.

FAQs

Common questions about silicone coatings.

Why choose silicone over acrylic elastomeric?

Silicone is often preferred where ponding water is common. Acrylic elastomerics can be a great choice when ponding is minimal and reflectivity is a priority.

How long does a silicone coating system last?

Service life depends on thickness, substrate condition, and maintenance. Many systems run 10–20 years with proper inspections and recoats as needed.

Will the roof be slippery?

Some coatings can be slick when wet. We recommend designated walk paths and can add walk pads or surfacing in service areas.

Can you coat over wet insulation?

No—wet insulation and trapped moisture must be addressed first. We moisture-scan and repair affected areas before coating.
