We use roof coatings primarily to shield roofs from environmental threats that could compromise their structural soundness. Using roof coating would help homeowners prevent water leaks, reduce the rate at which mould and moisture can destroy roof membranes, and lengthen the lifespan of their roofs. Waterproofing is a crucial issue that can accelerate the roof's deterioration, thus a roofing system without even a roof coating was missing a key point. If your roofing expert can find ways to improve the roof's durability and longevity, your roof may even outperform those of other similar buildings. Because of this, roof coating is crucial.
Roofing coatings are significantly thicker than paint and have a much higher elasticity. The elastomeric qualities that develop during curing provide for a coating that is both thick and resilient, able to close gaps of various sizes. Coatings for roofs, much like paint, exist in a wide variety of formulations to accommodate the wide variety of roofing materials. It's important to take care of the roof and all of its components to extend their useful life and keep them protecting your home. Roof coatings are commonly used to protect new roofs from the elements. However, paint is not adequate to protect the roof from the damaging effects of the sun, rain, wind, and snow. An existing roof can have roof coating put to it if it is made of a suitable material, such as a single-ply membrane, asphalt, BUR (tar and rubble membranes), EPDM, spray polyurethane, or metal.
Due to surface wear, roof coatings eventually need to be replaced. Expert roofers should be consulted for advice on the best coating to use on your roof. Hiring a professional roofing contractor can help you swiftly fix problems like leaks that won't go away, membrane damage, and poor insulation. An effective roof coating will seal all leaks, including those that aren't immediately apparent.
The lifespan of roof coatings is directly proportional to the thickness with which they are applied to the roof. Ten years is the maximum possible duration. If you know how to make the appropriate decision and how to increase the safety of your roof, you may be able to extend the life of your roof by many years. However, the extent to which roof coatings protect your home also relies on the local climate and other environmental factors. Looking for a roof replacement?

Roof Coatings And Their Durability
Coatings, like other types of roofing, have a finite lifespan. It has been shown that commercial roofs manufactured from alternative roofing materials also require maintenance over time.
Because of differences in coating thickness and quality, roof coatings have varying expected lifespans. However, depending just on roof system they are designed for, many coatings come with manufacturer guarantees of 5-10 years. One decade of trouble-free service from the typical roof coating is not an exaggeration.
But roof coatings have unique characteristics that set them distinct from other roofing materials. The subsequent characteristics describe these features:
- The roof coating is entirely bonded to the roof substrate rather than being fixed down in specific regions.
- Unlike other roofing materials, roof coatings are monolithic, meaning they don't have any seams (e.g., metal roof panelling, roofing sheet product)
- Roofing coatings typically outperform other waterproofing methods and do not necessitate the removal of the roof.
Roof coatings, which are totally bonded and seamless, are the ideal way to "upgrade" an older business roof so that it can survive ponding water, strong winds, or severe hail. The best part is that most coatings have excellent elastomeric qualities, meaning they can easily expand and contract in response to the sun's heat throughout the day.
Roof coatings are easily maintained and reapplied as needed, although not lasting for very long. Coating systems, when properly cared for, can last for decades with only one or two easy reapplications.
In the market for roof coatings, Conklin roof coatings are the best option. Conklin pioneered the use of acrylic roof coatings for commercial buildings in the 1970s. Since then, nearly 2 billion square feet of commercial roofing has been covered by Conklin materials. It has been claimed that Conklin roof coatings installed on buildings 40 years or more ago are still performing admirably. There are no other coatings on the market that come with a full 18-year, no-expenses-recovered warranty on both labour and materials. Their percentage of warranty claims is less than 0.5 percent, which is also quite low.
Roof Coatings Come In Four Varieties
Coatings come in a variety of styles, colours, and textures for commercial roofs. Facility managers should consult the manufacturer's material spreadsheet to select the right product for their needs, as there are significant variations in material compositions, applications, and application techniques. Incompatible or unsuitable coatings can ruin a roof's integrity. In addition, make sure that you get your roof ready for the roof coating by following the manufacturer's guidelines. All fluids and adhesives in use in roofing have a finite shelf life, thus it's crucial to store them properly on-site. Roof Repair & Restoration has a wide range of Melbourne roof restoration services.
Acrylic Finishes
Acrylic coatings were first used to shield sprayed urethane foam from the sun's rays. These coatings have found widespread application on metal roofing systems and single-ply membranes. Acrylic-based polymers offer the intrinsic flexibility needed to tolerate the dimensional instabilities of most roof cell membranes, and they also give good resistance to radiation damage and hail damage. Acrylate coatings that are designed correctly can lower the temperature rise by 20 degrees Fahrenheit when exposure to direct sunshine at 85 degrees Fahrenheit, according to certain research.
Acrylic coatings are made of 100% acrylic and can have one or more layers applied. Most manufacturers offer warranties at varying coverage levels; longer durations typically necessitate a higher level of coverage. Temperatures below freezing or the possibility of precipitation within a set time frame should prevent the installation of acrylic coatings. These items have a very narrow window of opportunity to cure, and curing will be slowed by either cold weather or heavy humidity. In order for something to cure properly, warm temperatures and low humidity are required.
As well as being cheap and highly reflective, acrylic coatings are also very user-friendly. These coatings, however, suffer from a reduction in mil thickness due to weathering, may only be applied at temperatures over 50 degrees Fahrenheit, and are easily damaged by ponding water.
Today, you may find instant-set materials from a number of different acrylic coating producers. This shortens the time it takes for the acrylic coating to cure, making it less likely that the coating will run off if it rains soon after being applied.
Coatings Made Of Silicone
Coatings made of silicone are typically made with a high solids' dispersion of pure silicone. The material is incredibly elastic and sticks very well to the current surface. Silicones are resistant to the effects of the weather and don't harden or crack easily. In the last ten years, silicone coatings have become increasingly popular for use on business roofs. The capacity of the material to endure long-term exposure with ponding water is largely responsible for the increase in uses, as most other coatings can withstand ponding water. Coatings made of silicone are not only resistant to oxidation but also do a great job of shielding their surfaces from the sun's rays in even the harshest of conditions. Silicone comes in a wide spectrum of colours, and it has excellent reflectivity and emissivity properties.
Only a select few materials (including silicone itself) can be linked topically to a silicone surface, which increases the barrier to entry and increases the cost. In addition, silicone attracts and retains dirt and gradually loses its reflective qualities.
Coatings Made Of Polyurethane
Sprayed-in-place foam roofing were the inspiration for the creation of polyurethane coatings. As of late, they have found widespread use as coatings on various preexisting roof membranes. With regards to impact resistance and wear and tear from foot traffic, polyurethane coatings rank highest. Polyurethane roof coatings can either be aromatic or aliphatic. As a rule, these components are utilised in tandem with base coat or topcoat. Though the topcoat material is tough, it does not provide much protection from the sun. For these reasons, as well as its resistance to UV light, cleanliness, and colour retention over time, aliphatic coatings are increasingly being used as top surfaces.
Asphaltic Rubber Membrane System With Fluid Application
Fluid-applied solutions have been developed to successfully and economically extend the service life of the current roofing system in response to technological advancements and labour shortages. For repairs that last longer, engineers created a cold-process fluid-applied asphaltic rubber membrane system. Rubber's elasticity is combined with the imperviousness to water and weather of an emulsified asphalt of the highest quality to create asphaltic rubber. The resulting blends are patented materials that cure into a single, seamless rubber sheet. The resultant membrane has a dry application thickness range of 20–200 mils.
Asphaltic rubber makes a monolithic, continuous membrane that immediately weatherproofs and waterproofs, unlike coatings that simply give a films surface or adhesive that require reinforcement for waterproofing capacity. When used in conjunction with coatings, these materials form a cost-effective and durable solution for repairing damaged areas.
Roof Coating Application Tips
A DIY enthusiast, are you? Do you feel confident enough to instal roof coatings on your own? You may save money and time by doing it yourself rather than employing a professional, and you'll realise how easy it is to do once you give it a try. EPMS liquid coating is compatible with a wide variety of substrates, including metal, concrete, neoprene, and more. So, let's have a look at the essentials for getting started.
When Is The Best Time To Do It?
Although it is probably obvious to most people, there are situations in which it is not a good idea to apply liquid roof coatings. Applying the coating on warm, sunny days will speed up the curing process significantly. If it has rained recently or if rain is predicted in the near future, you should wait until the weather clears before applying the coating. Moisture should be avoided at all costs.
Roof Surface Cleaning
Cleaning is always the first step. To ensure the roof coatings stick, the roof surface must be meticulously cleaned. Get rid of the bigger items first. Then, use a broom to remove some of the finer debris and dirt from the roof. It may look tidy and fresh right now, but don't be fooled. Still, a power washer can help you make sure you've removed everything from the roof.
Look For Additional Problems
The roof should then be inspected for damage, such as cracks or blisters. If any of them are noticed and are not too severe, a patch repairing kit can be used to fix them. Once you've assessed the state of your roof and are comfortable that things are under control, you may decide whether or not to hire a professional.
Roof Coatings Installation
Applying this coating is very comparable to painting. A lot of the same resources will be utilised. For instance, to cover a large area of your roof with coating, you'll need a roller with a long handle. The brush will be used for the last touches and to ensure that all the crevices and nooks are covered. Simply applying one application to your roof and you'll be finished.
After that, all you must do is wait for this to dry & cure. You must realise those are not the same. While the roof may be dry after a day, it will take many days to fully cure. Curing time can be weeks if damp weather persists.
As you can see, restoring and sealing a roof doesn't have to be difficult at all. If you don't feel up to handling it alone, though, you don't have to. To this day, expert assistance is still available. Roof Repair & Restoration has the best range of services if you’re looking for Melbourne roof repairs.
Conclusion
New roofs often have coatings applied to them for weatherproofing purposes. Any leaks in the roof, even those that aren't visible at first, can be permanently repaired with a high-quality coating. Consult professional roofers for guidance on the best coating for your roof. Fast repairs for issues like leaks and torn membranes can be facilitated by employing a skilled roofing contractor. Coatings on roofs wear out much like any other roofing material.
In many cases, the manufacturer's warranty on a coating will last for 5-10 years. The longest period of time is ten years. You might be able to keep your roof in good condition for a longer period of time if you know what to do. In the 1970s, Conklin was the first in the industry to apply acrylic roof coatings on commercial structures. Conklin products have been used to cover nearly 2 billion square feet of commercial roofing.
The 18-year, full-cost-reimbursement warranty is unmatched by any other coatings available today. Coatings with a low pH are inexpensive and highly reflective. Silicones don't harden or crack when exposed to the elements. When it comes to durability against impact and foot traffic, polyurethane coatings come out on top. Both aromatic and aliphatic coatings are possible for aliphatic substrates.
The lifespan of the current roofing system can be prolonged by using a fluid solution. In order to create a seamless and impermeable membrane, asphaltic rubber is often used. Liquid EPMS coating can be applied to many different materials, including metal, concrete, neoprene, and more. If you need any kind of roof repair in Melbourne, Melbourne Roof Repair & Restoration is your best bet. Support from knowledgeable people is still accessible today.
It could be dry on the roof in a day, but it will take many days for the roof to cure completely. Wet weather might extend the curing process by many weeks.

Frequently Asked Questions About Roof Coatings
every 4-6 years
How Often Do Roofs Need Recoating? Typically, a built-up roof requires routine maintenance and re-coating every 4-6 years. Ponding areas may need more frequent re-coating. Built-up roofs should be checked at least once a year for developing issues.
While we typically apply an acrylic elastomeric roof recoating every 18 years, a silicone roof recoating should occur every ten years. Silicone roof coatings, while not as durable as acrylic elastomeric, are often the better choice where severe precipitation and roof ponding is an issue.
If left unchecked for too long, it causes water to seep into the roof. The coating prevents such problems from threatening the building's structural integrity. It's advisable to coat your roof as a pre-emptive measure. This should ideally be done at least every five years.
Silicone. Silicone roof coatings are the preferred choice when it comes to UV protection and resistance to ponding water. They erode much slower than other coatings without becoming brittle or hard. Modern silicone formulations have a high-solids content that typically exceeds 90 per cent.
The Benefits of Applying Roof Coating
A roof coating is thicker than paint. It has elastomeric properties that enhance the roof's surface, producing a thick film that seals cracks between flashings, gutters, and tiles. Roofs without coats could easily damage roof membranes due to leaks.
