Our professional-grade coatings help stop leaks, reduce heat absorption, and restore aging roofs without the cost of a full replacement.

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 Joliet 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 Joliet IL 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 Joliet IL building and wind uplift codes

Our Commercial Roof Sealing Process
Free On-Site Roof Inspection
We evaluate your current membrane, flashing, insulation, and drainage system to determine if sealing is appropriate.
Roof Surface Prep
The roof is cleaned of dirt, grease, mildew, and debris. Power washing or soft washing is used to ensure optimal adhesion.
Priming and Detailing
We apply any needed primers, reinforce seams, reseal flashing, and patch small areas before applying the main coating.
Coating Application
We roll or spray on the roof sealant in one or more layers, following the manufacturer’s recommended thickness and cure time.
Final Walkthrough & Warranty
We perform a full post-sealing inspection and issue a manufacturer warranty (10–20 years depending on system).

Roof Sealing FAQs – TruRoof Joliet IL roofers
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 Joliet IL building codes?
Yes. All our sealing systems are Joliet IL 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 Joliet IL 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.
