We don't replace your roof. We make it stronger, longer-lasting, and leakproof.

  1. Deep Power Wash Prep
    Removes dirt, oils, & loose materials to ensure maximum adhesion. This step is what most companies skip — and it's why their coatings fail.

  2. Aromatic Polyurea Base Coat
    A flexible, self-sealing foundation layer that expands/contracts with your roof. Think of this as your shock-absorbing armor.

  3. Aliphatic Polyurea Top Coat
    The UV-resistant, weatherproof final layer that locks everything in. Keeps your roof cool, bright, and protected for decades.

Comparison chart of traditional flat roofs showing that acrylic/tar roofs have poor crack resistance, fade fast UV durability, are brittle, slow and disruptive to install, and not designed for Michigan weather protection. Polyurea roofs are rated as excellent in crack resistance, reflective and cool UV durability, expand and contract, are fast and non-invasive to install, and made for Michigan weather protection. The J&J Polyurea Roofing logo appears at the bottom right corner of the chart.

Why Commercial Property Owners Are Switching to Polyurea Roof Coatings

  • Designed to withstand heavy foot traffic, extreme weather conditions, and harsh chemicals, polyurea creates a tough, impact-resistant surface that extends the life of your commercial roof.

  • Unlike traditional roofing materials, polyurea forms a completely seamless membrane, preventing leaks, cracks, and pooling water that can lead to costly interior damage and mold growth.

  • Avoid expensive tear-off costs and disruption to your business. Polyurea coatings are applied directly over your existing roof, saving you time and money while delivering superior performance.

  • Polyurea coatings cure within seconds, allowing businesses to resume operations the same day without lengthy wait times or weather-related delays.

  • Polyurea maintains its structural integrity, preventing premature degradation while reflecting heat for enhanced energy efficiency.

  • By forming a highly insulating barrier, polyurea helps regulate indoor temperatures, keeping buildings cooler in summer and warmer in winter. This reduces strain on HVAC systems, cutting monthly energy costs significantly.

  • Wow. I got several quotes and Jason was by far the most knowledgeable. He was very honest and did not try to sell me on something I didn’t need. These guys run their business on a different level than everyone else. If you want the best product, by the most knowledgeable/honest people, at a very fair price, then call J&J.

  • I was finishing my lower level and trying to find a contractor that would not only do a great job at a reasonable price but also educate my wife and I on the process of spray foam which was new to us. Jason nailed it on both points. Provided prompt follow up completed the job on time and for the price quoted.

Frequently Asked Questions

  • Polyurea is a high-performance, spray-applied protective coating used in commercial and industrial roofing. It creates a seamless, waterproof, and highly durable barrier over your existing roof, extending its lifespan and improving energy efficiency.

  • SPF is a seamless, spray-applied roofing system that provides insulation, waterproofing, and structural reinforcement. It expands upon application, creating a thick protective layer that enhances durability and energy efficiency.

  • If your roof is aging, leaking, or has frequent maintenance issues, polyurea or spray foam can provide a cost-effective, long-lasting alternative to traditional roof replacement. A professional inspection can determine the best solution for your property.

    • Stronger & More Durable – Withstands extreme weather, impact, and heavy foot traffic.

    • Seamless & Waterproof – Eliminates leaks, cracks, and water pooling.

    • UV & Chemical Resistance – Protects against environmental wear and reduces cooling costs.

    • Cost-Effective Alternative to Roof Replacement – No need for a full tear-off.

    • Highest R-Value Per Inch – Reduces energy costs by providing superior insulation.

    • Renewable & Long-Lasting – Easily recoated every 10-20 years, extending lifespan indefinitely.

    • Self-Flashing & Seamless – Conforms to any shape, eliminating vulnerable seams and leaks.

  • Unlike traditional roofing that requires seams, fasteners, or adhesives, polyurea forms a seamless, monolithic membrane that resists leaks, cracks, and weather damage. It is also much thicker—up to 10X thicker than conventional coatings—providing enhanced durability.

  • Both options provide superior insulation. SPF roofing has the highest R-value per inch, significantly cutting HVAC costs. Polyurea’s UV reflectivity also helps reduce heat absorption, leading to a cooler building in the summer.

  • Installation time depends on the size of the project, but most commercial roofing projects can be completed within one day due to the rapid curing time of polyurea. SPF roofing also allows for quick application with minimal downtime for your business.

  • No, one of the biggest advantages is that both systems can be applied directly over existing roofing without a costly tear-off. This saves money, reduces waste, and minimizes disruption to your operations.

  • Routine inspections are recommended twice a year. Any minor damage can be easily repaired by recoating the affected area. Unlike traditional roofs, SPF and polyurea coatings do not require frequent repairs

  • With proper maintenance and periodic recoating, both systems can last over 50 years. They are highly resistant to environmental wear and are designed to be renewable and low-maintenance.

  • We offer a 20-year labor and material warranty for our commercial roofing solutions, ensuring long-term protection and peace of mind.

  • Yes. Unlike conventional roof replacements that require full tear-offs, these systems install over your existing roof, drastically reducing labor and material costs. They also lower long-term energy costs by improving insulation.

  • Yes! These coatings can be applied to a variety of commercial roofing materials, including:

    • Metal

    • Concrete

    • TPO

    • EPDM

    • Modified Bitumen

    • Built-Up Roofing (BUR)
