At Great Western Roofing, we use flat roof coatings to help commercial and industrial building owners protect aging roof systems, stop small problem areas from turning into major damage, and get more life out of the roof they already have. A roof coating is a fluid-applied restoration system that creates a seamless, protective membrane over an existing flat or low-slope roof. When the roof is a good candidate, coatings can be a smart alternative to a full tear-off because they improve performance, reduce exposure to leaks, and help control long-term roofing costs.
With 20 years of experience as a Utah commercial roofing contractor, we have seen how intense sun, heat, snow, ponding water, wind, and freeze-thaw cycles wear down flat roofing systems. That is why we take a practical approach. We do not just apply a product and hope for the best. We inspect the roof, identify weak points, make the needed repairs, and build a coating system that fits the roof condition, drainage, and use of the building.
What flat roof coatings are designed to do
Flat roof coatings are made to restore and protect existing roofing surfaces. They can help extend the service life of many low-slope commercial roofs, including single-ply roofing, metal roofing, modified bitumen, built-up roofing, and other approved substrates. Once installed properly, a coating system can:
- Seal and protect the existing roof surface
- Create a seamless waterproofing layer over many problem areas
- Help reduce UV damage and surface breakdown
- Improve reflectivity and energy efficiency on many buildings
- Reduce thermal movement that stresses roof materials
- Limit disruption compared to some full roof replacement projects
- Provide a cost-effective roof restoration option when the roof is still structurally sound
Many property owners come to us because they are dealing with leaks, weathering, cracked seams, aging surfaces, or rising maintenance costs. In the right situation, a commercial roof coating can solve those issues while preserving much of the existing roofing system.
Our process starts with a full roof evaluation
Not every flat roof should be coated. That is why our first step is always a detailed inspection. We look at the overall condition of the membrane or panel system, moisture concerns, open laps, punctures, flashing details, drainage, ponding areas, penetrations, curb conditions, and signs of movement or structural issues. If a roof has widespread trapped moisture, major substrate failure, or serious design problems, we will be honest about it and recommend a better solution.
If the roof is a good candidate for restoration, we put together a clear scope of work. That scope may include surface cleaning, repairs, seam reinforcement, flashing work, rust treatment on metal, replacing damaged sections, and applying the coating system at the proper thickness. Our goal is to do the job right so the coating performs the way it should.
What is included in flat roof coating service
Every building is different, but our flat roof coating projects often include the following steps:
- Inspection and moisture review: We assess roof condition and identify whether restoration is a good fit.
- Surface preparation: We clean the roof to remove dirt, chalking, oils, loose material, and biological growth. Good prep is critical for coating adhesion.
- Repairs before coating: We repair leaks, damaged seams, punctures, flashing details, and weak areas so the roof is ready for restoration.
- Detail reinforcement: Around penetrations, drains, seams, transitions, curbs, and other high-risk areas, we may use reinforcing fabric, mastics, primers, or specialty materials as needed.
- Coating application: We apply the specified coating in one or more passes to achieve the required dry film thickness and system performance.
- Final review: We inspect coverage, details, and workmanship to make sure the roof coating system is installed correctly.
This process matters because roof coatings are only as good as the preparation underneath them. We focus on the details that protect against future issues, not just the visible surface.
Common coating options for commercial flat roofs
We install roof restoration systems based on the roof type, budget, exposure, and performance goals of the building. Common flat roof coating options include:
Silicone roof coatings
Silicone coatings are a strong choice for many flat and low-slope roofs, especially where ponding water is a concern. They offer excellent weather resistance, UV protection, and long-term flexibility. Silicone systems are often used on commercial roofs that need durable waterproofing with strong resistance to standing water and sun exposure.
Acrylic roof coatings
Acrylic coatings are known for reflectivity and can be a good option for improving energy efficiency. These systems are often selected when reducing roof surface temperature and lowering cooling demand are important goals. Acrylic coatings perform well on many roof restoration projects when drainage is adequate and the substrate is in suitable condition.
Elastomeric roof coatings
Elastomeric coatings are designed to expand and contract with the roof. This flexibility helps them handle normal building movement and temperature swings. These systems can help bridge small cracks, protect aging roof surfaces, and improve overall roof performance when installed over a properly prepared substrate.
We help customers choose the right coating system based on the actual roof condition, not just what is popular. That guidance is important because the wrong product or wrong application can lead to early failure.
Roof types that may be good candidates for coatings
As a commercial and industrial roofing contractor, we work with a wide range of roof systems. Depending on condition and manufacturer requirements, coatings may be used on:
- Single-ply roofing systems
- Metal roofs
- Modified bitumen roofs
- Built-up roofing
- Previously coated roof systems
- Other low-slope commercial roof assemblies that meet restoration criteria
Because we also specialize in single ply roofing, metal roof systems, restoration, and energy-efficient roofing, we understand how coatings fit into the bigger picture. Sometimes a coating is the best answer. Other times, targeted repairs or replacement make more sense. We will tell you which option gives you the best value and the best long-term result.
Benefits of flat roof coatings for building owners
One of the biggest advantages of a roof coating system is that it can restore performance without the cost and disruption of a full roof tear-off in many cases. That can be especially valuable for occupied commercial buildings, industrial facilities, retail spaces, schools, and multi-building properties that need to stay operational during the project.
Key benefits may include:
- Extended roof life: Coatings can add years of service to an aging but repairable roof.
- Lower lifecycle costs: Restoration is often more affordable than replacement when the roof qualifies.
- Improved waterproofing: Seamless application helps protect vulnerable areas.
- Energy savings potential: Reflective roof coatings can reduce heat gain and support better energy performance.
- Less disruption: Many coating projects create less noise, debris, and interruption than tear-off work.
- Sustainable roofing option: Restoring an existing roof can reduce landfill waste compared to full replacement.
For many customers, the value comes down to planning ahead. If a roof is showing age but has not failed beyond repair, a coating can be a smart way to protect your investment before conditions get worse.
Why proper preparation and installation matter
Roof coatings are not a shortcut. A successful system depends on the contractor understanding substrate condition, repair methods, weather windows, material compatibility, and application rates. If the roof is not cleaned correctly, if seams are not addressed, or if the coating thickness is off, the system may not perform as intended.
That is where experience matters. At Great Western Roofing, we bring 20 years of commercial roofing experience to every project. We have worked on everything from schools to large retail buildings, including Walmarts in Utah and Wyoming and Daniels Canyon Elementary. We understand the standards required on commercial properties, and we back our workmanship with a guarantee. As Owens & Corning Certified Master Applicators, we are committed to high-quality installation and dependable service from start to finish.
When a flat roof coating may be the right choice
A coating system may be worth considering if your flat or low-slope roof is showing signs of age but is still in restorable condition. Common signs include:
- Small recurring leaks
- Surface wear from UV exposure
- Drying, cracking, or weathering
- Seam or flashing deterioration
- Rusting on aging metal roof sections
- Higher roof temperatures and poor reflectivity
- A need to extend roof life before budgeting for replacement
If you are not sure whether your building is a good candidate, we can inspect it and give you a straightforward recommendation. We do not push coatings where they do not belong. Our job is to help you make the right roofing decision for your property.
