Avoid the unnecessary costs of roof replacement when a roof coating may solve your roofing problems. Knowing how roof coatings are applied to existing roofing systems can help you save money while extending the lifespan of your roof.

atlantacommercialroofingcontractors.com gathered the following information and tips about roof coatings and their advantages when applied to your roofing system.

What Are Roof Coatings?

Roof coatings are monolithic, fully adhered, fluid-applied roofing membranes. Roof coatings are typically applied to cover, protect, and extend the lifespan of a structure’s roofing system. Many roof coatings are elastomeric, having elastic properties that allow them to stretch and constrict to their original shape without suffering any damage or deformities.

Are Roof Coatings Worth it?

Yes. Coatings are often seen as an economical way of increasing a roof’s reflectivity. Thus, reducing a structure’s cooling and heating costs. However, a coating is not always necessary if enough insulation is installed with the original roofing system.

Applying a roof coating can add extra protection to a roofing system’s components, adding years or decades to its lifespan.

Considering the lowered air conditioning and the building’s roof preservation, applying a roof coating is worth the investment as it will likely pay for itself over time.

What Are Types of Roof Coatings?

Depending on the type, size, and geographical location of your roofing system, one of the following roof coatings may be applied to your roof:

Metal Roof Coating – Metal roof coatings stop leaks, eliminate stubborn rust, and turn hot metal surfaces into a cooler energy-saver. This could be considered metal roof restoration when preparations are made before this weather and heat-shielding coating is applied.

Note: Commercial metal roof coatings start saving you money immediately. Since it is a reflective roof, it can reduce roof temperatures by 30%. This means that heat isn’t transferred to your building, which significantly reduces energy use.

Flat Roof Coating – Flat roofs are typically plagued with leaking, ponding, drainage problems, and rapid deterioration. Whether your current roofing system is hot-tar, modified bitumen, built-up, single-ply, metal, or polyurethane foam, you can apply a roof coating that adds up to 20 more years of useful roof life.

Rubber Roof Coating – Silicone roof coatings are the preferred choice regarding UV protection and resistance to ponding water on rubber roofing systems. They erode much slower than other coatings without becoming brittle or hard.

Extend your existing roof’s lifespan while adding energy efficiency and extra protection for your commercial, industrial, agricultural, or residential structure. Rubber roof coatings can efficiently solve current problems and prevent them from recurring.

Elastomeric Roof Coating – These roof coatings are applied to your roofing system as a liquid. After application, the acrylics dry to a seamless, clean coating that significantly extends roof life.

Note: Correctly installed elastomeric roof coatings are practically weatherproof and can keep your property shielded from most weather conditions. The coating material is elastic, so it can expand and contract as the weather and temperature change.

Cool Roof Coating – Cool roof coatings, or cool roof paint (as it is known in the roofing industry), is a coating that’s applied to a variety of roofing systems to better reflect sunlight, keeping buildings cooler on the inside and significantly reducing energy costs.

Tip: Reducing a structure’s air-conditioning usage will naturally extend its cooling equipment’s lifespan, decreasing maintenance costs and saving you even more money.

When considering a roof coating, be mindful that mechanical fixes to your roofing system are always a better choice than coatings to stop leaks or repair cracks. If you discover leaks, cracks, or other damages, replace and repair them before applying a coating or sealant.

Roof Coating Installation Costs

According to homeadvisor.com, you can expect to pay anywhere between $0.65 and $5 per square foot for an installed roof coating or sealing. Variables can include:

• Type of roof
• Type of coating or sealant
• Condition of the current roof
• Geographic location

Coating a flat or low-sloped roof is a common way to extend the life of your roof while reducing maintenance expenses and cutting down on cooling costs.

Note: Costs for roofing material and installation vary significantly and are heavily influenced by demand, supply chain interruptions, inflation, and fuel/transportation expenses.

Prevent your failing commercial roof from shuttering your business, costing you valuable time and money. Commercial roof coatings can extend the life of your current roofing system by twenty years or more,

atlantacommercialroofingcontractors.com gathered information about commercial roof coating purpose, benefits, installation, types, and maintenance for you to make informed decisions when your commercial roof needs attention.

Commercial Roof Coating Purpose

The purpose of commercial roof coatings is to improve the performance of your roof and increase its lifespan.

Commercial roof coatings protect your property by creating a seamless layer of protection that self-adheres to your existing roofing system. The majority of these coatings are reflective and do not absorb UV rays, keeping your roof and property cooler (making your roofing system a “cool roof”), saving energy and money.

Commercial Roof Coating Benefits

As previously mentioned, commercial roof coatings can help you save money by reflecting UV rays. The benefits don’t stop there, consider the following when determining if a roof coating is the right choice for your building:

No Leaks – Commercial roof coatings eliminate leaks from your roofing system. You may rarely wind up with a leak, but they are easy to fix.

Cool Roof – High solar reflectance (albedo) is the most critical characteristic of a cool roof as it reflects sunlight and heat away from a building, reducing roof and internal temperatures. A high thermal emittance also positively contributes to lowering heat-island temperatures in climates that are warm and sunny.

These properties help roofs to absorb less heat and remain up to 50–60°F cooler than conventional materials during the summer months.

Resistant To Ponding – When your roofing system’s drains get partially or entirely interrupted, water will back up and settle in the lowest areas of the roof. Due to the coating’s seamless application, water penetration is prevented until you can correct the problem with the drainage system.

Low-Cost Solution – A commercial roof coating application is an inexpensive alternative to roof replacement that, when properly applied, can significantly extend the life of your roofing system, making its cost-benefit even greater.

• $8,000 to $16,000 is the range you can expect to pay for a 1,600 square foot flat roof installation (materials and labor).
• $1,040 to $8,000 is the range you can expect to pay for a 1,600 square foot roof coating application (materials and labor).

Longevity – Creating a watertight barrier over your original roofing material can extend its lifespan by as much as 20 years.

Versatility – Commercial roof coatings can adhere to a wide range of substrates. Occasionally, a primer is needed for the coating to adhere to the substrate (more on this below).

Easy Installation – When applying a commercial roof coating, contractors will save time and headaches. At the same time, building owners can get their roof revamped faster for less money and without interrupting operations within the building.

While there are impressive benefits associated with nearly every aspect of commercial roof coatings, if your roof has suffered catastrophic damages or has completely failed, it may be necessary to replace it altogether.

Commercial Roof Coating Installation

A roof coating installation is a simple process. As mentioned above, it is one of the benefits. The following will bring into focus just how easy it truly is:

Roof Inspection – A roof inspection is the first step in this process, and the professional performing it will be looking for the following:

• Storm, animal, or impact damages
• Shrinkage (membrane roofing systems)
• Damaged sheet metal (metal roofing systems)
• Damaged flashing
• Loose protrusions
• Drain blockages
• Pooling water
• Previous or current leak damage
• Structural integrity

These inspections are most effective when performed within 48 hours after rainfall.

Roof Repairs – Once your inspection is done, you’ll have a list of damages or irregularities to fix. Before you can apply a roof coating, all problems must be halted and removed. If a roof coating is applied to a roof with wet insulation, loose protrusions, structural problems, etc., those problems will be sealed in and continue to cause problems.

Clean the Roof – Once all repairs are complete, the final activity before installation is to clear the roof of:

• Tools and equipment
• Debris
• Dirt
• Oil/Exhaust buildup

Remove everything that is not a part of the roofing system. Using a power-washer, brooms, and industrial vacuums are effective ways of cleaning your roof before coating application.

Install the Roof Coating – After the roof has been inspected, repaired, and cleaned, your roofer can properly apply your roof coating. Coatings can be applied by rolling them on or spraying them on the roof’s surface. Done correctly, the coating will cure over 24 hours, leaving your roofing system rejuvenated and sturdy for up to 20 years.

Commercial Roof Coating Types

The following are common types of roof coating that can be applied to your existing commercial roofing system:

Acrylic Coatings – Acrylic coatings come in solvent and water-based formulas, and the qualities of the coating depend on the selected formula. Acrylic coatings have outstanding weathering properties and reflect UV rays. The selection of a formula depends on the type of the roof, adhesion, regional temperature fluctuations, etc.

Silicone Coatings – Silicone coatings are commonly applied in regions subject to an abundance of rain, leaving the roof wet for long periods. These coatings are also highly effective at reflecting UV rays, helping commercial structures stay cool.

Butyl Elastomeric Coatings – Butyl elastomeric coatings are made from butyl rubber and possess excellent flex properties, adhesion to multiple substrates, and resistance to most weather and temperature conditions.

Polyurethane Coatings – Polyurethane coatings are solvent-based and come in either aromatic or aliphatic variations. Polyurethane coatings have high abrasion resistance traits and are preferred on roofing systems with high foot traffic or regions that experience frequent hailstorms.

Commercial Roof Coating Maintenance

Should you acquire a maintenance program to cover your roof coating and roofing system?

Yes. In the same way you would contract a professional roofing service to maintain your roof without a roof coating, you should acquire an equivalent maintenance program once your roof coating is installed. Some of the benefits include:

• Bi-annual inspections
• Emergency inspections after severe weather
• Light maintenance and repairs
• Preventive maintenance
• Gutter and drain cleaning
• Debris removal

Commercial Roof Recoating

One of the added benefits to getting a roof coating is that once you near the end of its lifespan, you can have it recoated, adding another 15 to 20 years to the life of your roofing system.

Note: Some municipalities have codes that address commercial roof recoating and may limit the number of times a roof can be coated before requiring repair or replacement. Visit your city’s website and search for “roofing codes” or call their “Office of Buildings/Construction” for more information.

Coating Your Commercial Roof

In this article, you discovered information about the purpose, benefits, installation, types, and maintenance programs associated with commercial roof coatings.

By informing yourself about commercial roof coatings, you can make well-informed decisions when it’s time to address roofing issues, or take action to prevent them.

Allowing your roof to remain fully exposed to the elements can dramatically reduce its lifespan, leading to premature problems and failure. Significant problems or premature replacement can lead to you exceeding your roofing budget and costing your company capital that could be used in other areas.
