What Is Commercial Roof Sealing?

Commercial roof sealing, also known as roof coating or restoration, involves applying a seamless, weather-resistant membrane over your existing roofing system. This process renews your roof’s surface without full removal or downtime.


At TruRoof Evanston IL, we use premium-grade sealants including:


  • Silicone Roof Coatings – best for ponding water resistance
  • Acrylic Coatings – cost-effective and reflective
  • Polyurethane Roof Sealants – high-impact and chemical-resistant
  • Elastomeric Coatings – flexible and durable for harsh Florida conditions

The Smart, Cost-Effective Alternative to Full Roof Replacement

Not every leaking or aging roof needs to be torn off. If your flat roof is structurally sound but showing surface damage, UV degradation, or minor leaks, a commercial roof coating system can restore its performance for a fraction of the cost.


Our high-performance roof sealants are designed to:


  • Stop active leaks
  • Reflect sunlight and lower rooftop temperatures
  • Improve waterproofing and drainage performance
  • Extend your roof’s life by 10–20 years
  • Improve ENERGY STAR® efficiency
  • Meet Florida’s building and wind uplift codes

Roof Sealing FAQs – TruRoof Evanston IL

  • How long do roof coatings last?

    High-quality coatings last 10–20 years, depending on the product type and environmental exposure.

  • Can a coating stop roof leaks?

    Yes. When applied correctly, commercial roof coatings can seal small leaks, prevent future intrusion, and waterproof the entire surface.

  • What’s the difference between roof repair and sealing?

    Repairs target specific damage. Sealing involves coating the entire surface with a continuous membrane, essentially restoring the roof.

  • Is sealing cheaper than replacing a commercial roof?

    Yes. Sealing typically costs 40–60% less than a full replacement and can be completed with far less disruption.

  • Can all roofs be sealed?

    Not all. If your roof has structural issues, wet insulation, or severe membrane failure, a full replacement may be required.

  • Will this meet Florida building codes?

    Yes. All our sealing systems are Miami-Dade County approved, UV and fire-rated, and meet state wind uplift standards.

  • How much does commercial roof sealing cost?

    Typical pricing ranges from $2–$6 per square foot, depending on prep work, material used, and roof complexity.

  • Do you provide warranties?

    Yes. Most systems include 10–20 year manufacturer warranties, plus TruRoof Spring Hill’s workmanship guarantee.

  • Can sealing improve my building’s energy efficiency?

    Absolutely. Reflective white coatings can lower rooftop temps by up to 40°F, reducing HVAC loads and energy bills.
