Flat Roof Coating Services to Protect Your Commercial Property

A roof coating applies a liquid sealant or coating atop an existing roof membrane. The roof coating application is either rolled or sprayed on the entire existing roof surface. As the liquid is applied, it spreads and binds together to create a seamless roof coating.

The experts at Metro City Roofing offer complete roof coating services, starting with a FREE ROOF INSPECTION. We provide detailed documentation with photos and video, including a thermal camera to identify if your commercial roof would qualify for a roof coating.

This flat roof coating service extends the life of the existing roof, and with a reflective type coating, it becomes an energy saver. This coating creates an environmentally friendly structure that reduces the carbon footprint. This flat roof coating technique has grown in popularity because it contracts and expands with the weather changes and doesn’t leave the roof unprotected.

Coatings are appealing for many business owners, property managers, and homeowners with flat roofs for several reasons, including:

  • Seals and prevents future roof leaks
  • Extends your roof’s life with a long-term warranty of 10-20 years
  • More cost-effective than completely tearing off and replacing your existing roof
  • No city or county permit is required since a roof coating is considered maintenance and does not count as another layer of roofing materials
  • Offers added protection against hail and storm damage
  • Avoids costly upgrades to the most recent code requirements
  • Reduces energy costs since most roof coatings have reflective properties and reflect ultraviolet (UV) rays
  • Installation is quick, often completed within several days for smaller buildings
  • Minimal to no disruption to normal business activities

The best time to install a roof coating is before your roof begins to display issues such as minor leaks, seams that lift or are already loose, or flashings such as pipe jacks that have cracks or noticeable tears of holes that invite water inside the building. If any of these have already occurred, a roofing contractor will need to complete commercial flat roof repairs before beginning a coating project.

The Process of Installing Roof Coating Over Flat Roof

The roof coating application consists of three main installation steps: surface preparation, including repairing and sealing all seams, applying a primer coat, and the actual coating application.

Free flat roof inspection

Critical insight before your free flat roof inspection

Once you contact us to schedule a flat roof inspection, we will have several questions, including:

  1. Does your building have any active roof leaks?
  2. When was your commercial roof last inspected or repaired?
  3. What is your roof’s age?
  4. What type of roof material is currently installed?
  5. What is the approximate size of the roof in square feet?
  6. How many stories is the building?

Once we capture this essential information, we will schedule a free roof inspection.

Thorough inspection and documentation

The professionals at Metro City Roofing will complete a thorough flat roof inspection, carefully looking for any standing or ponding water, inspecting all seams and flashings for water penetration points. We document everything with photos and video, including a thermal infrared camera to detect moisture that has already entered underneath the roof’s top layer.

Following our inspection, we will share our inspection results to discuss recommended actions. If we recommend a flat roof coating, we will need to bring out a manufacturer’s rep to complete an inspection to confirm that your roof will qualify for a warranty with the finished roof coating. Suppose there is extensive water saturation that damages the roof’s substrate and insulation. In that case, the roof will unlikely qualify for a coating, as the roof coating will not adhere and perform properly. At times, we may require a commercial repair to the existing roofing material before beginning the roof coating. Any affected, damaged section will need to be removed and replaced using the same matching materials when this occurs.

Metro City Roofing is the only call you need to make for Colorado homeowners in need of a high-quality roofing contractor.


Commercial Roof Coating Materials for Low Slope & Flat Roof Systems

There are two different commercial roof coating products – acrylic and silicone. Both materials provide numerous money and energy-saving benefits and can add years of serviceable life to aging commercial roof membranes.

While silicone coatings are superior to acrylics in a lot of ways, it doesn’t mean they are the most appropriate solution for every roof coating project. Choosing the best roof coating depends on a number of critical factors.

An acrylic coating is a less expensive, water-based option. It works excellent for specific locations like Arizona, where there is little rain and snow. An acrylic coating cannot typically be installed in Colorado during the winter months since it cannot freeze for 48 hours. An acrylic coating is an excellent option for metal barns.

When you want higher-quality, a silicone coating is better but more expensive and works best with TPO, EPDM, PVC, and modified bitumen.

Acrylic Roof Coatings

Elastomeric coatings have proven very effective in solving roof leaks and extend the life of low slope and flat roofs. An acrylic roof coating is an elastomeric water-based roof system applied over various roofing materials like asphalt built-up roofs, modified bitumen, metal, EPDM, TPO, and PVC.

Acrylics offer exceptional exterior durability and UV stability and are an excellent choice for more budget-conscious building owners, property managers, and homeowners with low slope and flat roofing systems. Acrylics work best when a roof has no ponding water, over a metal roof with minimal rust, or when installation temperatures are above freezing.

At Metro City Roofing, our effective roof coating solutions achieve waterproofing protection to stop leaks and extend your roof’s life. An acrylic elastomeric roof coating is one such product. Acrylic coatings provide a practical solution for roof protection and restoration applications, delivering multiple valuable benefits, including ease of application, reflectivity, durability, and cost-effectiveness.

We look forward to discussing the best flat roof coating option for your property and budget.

Silicone Roof Coatings

Silicone is gaining notoriety as the flat roof coating go-to material. A silicone roof coating offers numerous benefits including, leak-free protection, enhanced sustainability with UV protection, and improved design aesthetic. A silicone roof coating could be the best way to extend the life of your commercial roof for decades, with additional recoating applied as necessary.

Silicone is durable and flexible, offering superior protection from nature’s elements in wind, hail, and rain. It also provides UV stability, providing maximum long-term performance against weather and atmospheric conditions. UV stability is critical in Colorado, where the UV exposure to roof systems is extreme. Choosing a brighter color for your silicone coating will also help to reflect the sun’s rays.

A silicone flat roof coating can be applied over new spray-applied polyurethane (SPF) foam, EPDM, TPO, aged PVC, aged acrylic coatings, concrete, asphalt built-up roofs, granulated modified bitumen, and metal roofs.

Silicone coatings are the best material choice when a roof has ponding water, or a complex roof provides installation issues for a conventional membrane roof.

Look no further than Metro City Roofing for the best silicone roof coating in metro Denver and across the Front Range.


Roofing Materials You Can Apply a Roof Coating

A roof coating is an available option for most roofing materials, provided the roof is free from water penetration. The following are types of roofing materials where a coating can be applied:

TPO roof coating

Popular, Reflective, and Energy-efficient

Thermoplastic polyolefin (TPO) is a prevalent material used in commercial roofing. TPO is highly reflective and energy-efficient, and typically white. The cost-effective white roof reflects up to 78 percent of the sun’s rays, reducing cooling costs.

TPO membranes, however, have low surface energy, making adhesion difficult. Adhering a roof coating to TPO membranes requires either sanding, scuffing, priming the surface.

EPDM rubber roof coating

Very Durable And Low Maintenance

Known for low maintenance and its ability to withstand all types of weather, EPDM (ethylene propylene diene monomer) is optimal in many geographies. In northern climates, a black EPDM membrane harnesses solar energy, equating to reduced heating costs in the winter.

An EPDM membrane is very durable with excellent weathering properties but poor chemical resistance to solvents. Many solvents make an EPDM membrane swell and deteriorate.

Commercial roofing manufacturers recommend either an acrylic or silicone coating to extend the life of an EPDM roof.

PVC roof membrane coating

The Original White Commercial Roof

Polyvinyl Chloride (PVC) is the original white roof with more than 30 years of proven track record. PVC in its natural state is rigid. Adding plasticizers make PVC flexible for use as a roofing membrane but challenging to coat.

As PVC ages and plasticizers migrate out of the membrane, it becomes a candidate for a roof coating.

Metal roof coating

Preventing Corrosion and Rusting

A metal roof is a wise investment to increase a property’s value, longevity, energy efficiency, and sustainability.

Metal roof panels must be structurally sound to provide a safe work environment and a suitable surface for a coating application. Acrylics and silicones require treating any rust before coating.

Modified bitumen roof coating

Popular On Residential Flat Roofs

Modified bitumen roofs are popular for residential flat roofs, especially when matching the flat roof section with the pitched roof portion that has asphalt shingles.

You can coat a modified bitumen roof, but asphalt roofs contain oils. A modified bitumen roof should age a minimum of 90 days before applying a coating to allow the oils to leave the membrane. Still, aged asphalt and modified bitumen have enough retained oil to cause staining.

Any coating applied over asphalt or modified bitumen should have a stain blocker applied. This will prevent color staining.

Metro City Roofing is proud to be a Warranty Eligible Contractor for commercial roof coatings, offering up to 20-year warranties.

Gaco Roof Coating to Extend The Life Of Your Roofing System

Gaco products are known for their excellent adhesive properties, which allow the silicone coating material to bind with the existing roofing material.

A silicone coating can be applied to almost any flat roof surface, except architectural shingles or 3-tab asphalt roofs, providing versatility for contractors and building owners. Gaco roof coatings installed by a certified contractor are available with up to a 20-year warranty.

Choose The Flat Roof Coating as Cost-Effective Alternative to Roof Replacement

A roof coating is an excellent alternative to a roof replacement, provided there is no water underneath the roof substrate. The primary benefit of a flat roof coating is to extend the life of an existing roofing system. It is also substantially less expensive than a roof replacement.

Roofing contractors do more than repair leaks and complete roof replacements. It may make sense to prolong a roof’s life with a quality roof coating for your commercial flat roof.

Roof coatings have progressed from a maintenance decision to a long-term investment with No Dollar Limit (NDL) warranties up to 20 years.

Contact the professionals at Metro City Roofing for your FREE ROOF INSPECTION to learn the condition of your commercial roof and if a roof coating is right for you.

How Much Does It Cost To Coat A Flat Roof?

On average, a roof coating will cost approximately $5-$8 per square foot (SF) of roof surface. Thus, a 3,000 SF roof will cost between $15,000-$24,000.

The actual flat roof coating cost will depend on several variables, including the size of the roof, type of roofing material the coating will be applied to, roof coating material to be used, the desired or necessary thickness of the coating, and overall accessibility to the building for the roofing contractor.

With Metro City Roofing, our process starts with a FREE ROOF INSPECTION. We also respect your time and schedule actual appointment times, unlike other roofing companies that schedule several-hour windows and make you stay home waiting for them. Call us today.

Answers to Common Questions Asked by Our Customers

A roof replacement includes tearing off all layers of a roofing system and installing a completely new roof. A roof coating adds a protective layer of acrylic or silicone to protect against water and weather applied to an existing roof. A coating is applied by brush, roller, or spray and can extend the life of a roof up to 20 years. Due to the material used and weight, an additional coating may be applied in the future, further extending the roof’s life and avoiding any structural damage.

A roof coating is more cost-effective than a complete roof replacement. The reason is that a roof coating is an application on top of the existing roof. A roof replacement includes tearing off the existing roof down to the roof deck and installing a new roof. All roof replacements must be permitted and meet current code requirements at the time of installation. For commercial properties, this includes insulation under the roof membrane, which can be very expensive.
