Types of Roof Sealants and Coatings for Commercial Roofs
Choosing the right sealant or coating is crucial for protecting your commercial roof from leaks, UV damage, and wear. Different products offer specific benefits, including weather resistance, flexibility, and energy savings. Understanding these options helps us apply the best solution for each roof type.
Acrylic Roof Sealants
Acrylic coatings are water-based and provide a highly reflective, durable finish for commercial roofs. They are breathable, allowing moisture vapor to escape, which reduces the risk of blistering under the coating. This makes acrylic sealants a great choice for flat or low-slope roofs prone to ponding water.
These sealants adhere well to most roof substrates and are cost-effective. However, they are less durable in standing water conditions and may require reapplication every 5-10 years depending on climate stresses. Acrylic coatings also provide good UV resistance, helping lower building energy costs by reflecting sunlight.
Silicone Roof Coatings
Silicone roof coatings offer excellent waterproofing and superior resistance to weathering and UV exposure. Their strong adhesion creates a seamless barrier that resists ponding water better than acrylic coatings. This makes silicone ideal for roofs with water drainage issues or harsh climate conditions.
We appreciate silicone’s longevity and elasticity, which allows it to expand and contract with roof movements without cracking. These coatings are typically more costly but provide extended service life and energy savings by reflecting sunlight. Silicone roof coatings bond well with various materials like metal, modified bitumen, and asphalt.
Elastomeric and Polyurethane Solutions
Elastomeric roof coatings provide exceptional flexibility and crack-bridging properties, ideal for roofs experiencing frequent temperature changes. They withstand surface movement while maintaining waterproofing integrity, making them a preferred choice for older roofing systems.
Polyurethane roof sealants and foam deliver highly durable waterproofing along with insulation benefits. Polyurethane foam expands to seal gaps, offering excellent protection against leaks and improving energy efficiency. These products are effective for roofs requiring extra durability and thermal resistance.
The Commercial Roof Sealing Process
Our approach to commercial roof sealing involves careful evaluation, precise application, and ongoing maintenance. Each step is designed to protect your TPO roofs and other flat roofing systems from leaks, UV damage, and energy loss.
Professional Roof Inspection
We begin with a thorough roof inspection to identify existing damage and areas vulnerable to leaks. This includes checking seams, flashing, and the condition of the current TPO roofing membrane. Heat-welded TPO roofing systems demand particular attention to seams, as improper sealing here can cause moisture infiltration.
During inspection, we also assess ponding water spots. Standing water weakens roofing materials and accelerates wear. We document cracks, brittle sealants, and damaged flashing as candidates for repair.
Sealant Application Techniques
We apply advanced sealants suited to your roofing materials, including silicone, acrylic, or polyurethane coatings optimized for energy-efficient TPO flat roofs. Application starts with cleaning and drying the surface to ensure adhesion.
Seams and crevices receive special focus, with roofing cement or fabric reinforcement used to reinforce weak points. For large areas, we utilize spray polyurethane foam or liquid-applied coatings that cure into seamless, waterproof membranes.
Post-Sealing Maintenance
Sealing your commercial roof is an investment that requires regular care. We recommend scheduling roof inspections at least twice a year to monitor the sealant’s condition and check for new damage.
Cleaning debris, clearing drainage systems, and examining flashing are essential to maintaining seal integrity. Minor cracks or wear spotted during inspections should be repaired promptly to prevent costly roof repair.

Commercial Roof Sealing FAQs
How much does commercial roof sealing cost per square foot?
Commercial roof sealing typically costs $2-$4 per square foot, depending on the sealant type and roof condition. Silicone-based sealants cost more than acrylic or aluminum coatings but offer superior protection. Factors affecting cost include roof accessibility, necessary repairs before application, substrate type, and required preparation work. For larger projects exceeding 20,000 square feet, we offer volume pricing discounts.
What are the energy-saving benefits of commercial roof sealing?
Reflective roof sealants can reduce cooling costs by 15-30% by reflecting up to 85% of solar radiation. ENERGY STAR certified roof coatings can lower roof surface temperatures by up to 50°F and decrease peak cooling demand by 10-15%. Our commercial-grade silicone and acrylic sealants meet Cool Roof Rating Council standards for solar reflectance and thermal emittance, qualifying many buildings for energy rebates through ComEd and Illinois energy efficiency programs.
How long does a commercial roof sealing treatment last?
Premium silicone roof sealants typically last 15-20 years, while acrylic coatings provide 7-10 years of protection when properly applied. Aluminum-based sealants generally last 5-7 years. Factors affecting longevity include local climate conditions, roof traffic, maintenance practices, and initial application thickness. We offer extended warranty options when combining our sealing service with our preventative maintenance program.
Which roof sealing systems work best in Joliet's climate extremes?
For Joliet's varied climate, high-solid silicone sealants provide superior performance, maintaining flexibility in winter temperatures as low as -40°F while resisting UV degradation during hot summers. Hybrid polyurethane-silicone systems also excel in our freeze-thaw cycles. For metal commercial roofs, elastomeric coatings with rust inhibitors provide additional protection against moisture and thermal movement common in northern Illinois.
Can roof sealing prevent leaks on aging commercial buildings?
Yes, professional roof sealing can stop and prevent leaks on aging commercial roofs by sealing micro-cracks, reinforcing weakened seams, and creating a waterproof barrier. Our seamless membrane application encapsulates aging substrates, extends roof life by 5-10 years, and addresses up to 90% of common leak sources. For buildings with 5+ years of expected use before replacement becomes necessary, sealing offers an economical alternative to premature roof replacement.
