If you are a homeowner, you should look for ways to extend the lifespan of your roof. In this case, the best solution is to coat your roof to protect and restore it. Besides repairing leaks, roof coating helps protect your roof against hail, rain, sunlight and other harmful natural elements. As a result, this helps you get the most out of your roof.

What Is Roof Coating?

Roof coating is a fully adhered fluid with elastic properties. When applied on a roof, it increases its lifespan. The fluid can stretch and return to its original shape undamaged. Compared to paint, roof coatings are thicker and have higher solid contents.

They are specially designed to protect roofs against the harmful effects of the environment and weather such as excessive water, UV light, and the wind. Since they are extremely elastic, they can provide protection to your roof for many years. Moreover, their high-quality resin helps improve their effectiveness.

The Main Benefits of Roof Coating

#1. Saves Money

Roof coatings are usually applied to low slope roofs on commercial, industrial and residential buildings to prolong the lifespan of a roof by avoiding chemical, water or physical damage. As a result, the owner of the building saves money. Some types of roof coating can even provide an additional level of waterproofing protection to aid shed water and keep the interiors of a building dry. Roof coating is considered the least costly and most efficient option to help buildings to save energy.

#2. Increased Roof Life

Roof coating helps increase the lifespan of your roof. You may choose to perform minor repairs by yourself. Otherwise, you may hire professionals to coat, repair and restore your old roof. A professional can repair leaking roofs and can identify, remove and patch affected areas prior coating.

#3. Reduces Construction Debris

According to recent estimates, roofing projects account for about 45% of construction waste. Applying a coating to the roof at the best time during the life cycle of your roof can help improve your roof’s state. You will, therefore, not need to tear off and dispose of your roofing membrane and old insulation which ends up in the landfills.

#4. Reduced Energy Use

Most roof coatings are well-known for their emissive and reflective properties. These features help roof coatings minimize roof temperatures, leading to decreased energy consumption requirements especially during the day. With reduced roof temperatures and reduced energy use requirements, the workload of HVAC systems is considerably reduced. In the long-run, your energy expenses will go down.

#5. Aesthetic Improvements

Instead of replacing an aging and unattractive roof for aesthetic reasons, roof coating can help improve your roof’s appearance. Moreover, roof coatings are available in various colors to suit your style. It is, therefore, safe to say that the best way to improve the overall appeal of your home is by roof coating.

#6. Micro-Climate Management

Roofing membranes are susceptible to early wear and tear and eventual leakage, especially low slope roof areas. Similarly, roof areas exposed to harmful wastes can experience localized failure. However, applying the best coating products on the affected areas can help extend the lifespan of the whole roof system. Inability to implement this sustainable approach can result in structural deterioration, leaks, wet insulation and premature replacements.

Note that, coating your roof isn’t the best solution all the time. Sometimes, roof coating can be more costly than anticipated and can lead to undesirable outcomes. If you happen to see either of the following conditions on your roof, you might need to consider other options rather than roof coating application.

#7. Failing Roof Systems

Although roof coating can help prolong the lifespan of your roof, you shouldn’t use it as a substitute for roof replacement. Some conditions such as roof system adhesion loss and widespread wet insulation might require you to replace your roof altogether. In these situations, coatings might only restore the watertight nature of your roof for a short time.

Even with a good coating in such circumstances, wind-uplift damage especially at neglected areas, undercoating splitting, weak areas hail damage, thawing and freezing of wet insulation can still occur. As a homeowner, it would be wiser to consider replacing your roof system in such cases.

You can use roof coating to sustain your roof especially after contaminant exposure or if it has ponding issues. However, a coating is not an ideal option if your roof has issues related to surface preparation. You should not apply coating if the surfaces of your roof are difficult to prepare.

The Main Types of Roof Coating

#1. Acrylic Roof Coating

This is a water-based coating solution that is cost efficient and Eco-friendly. It is highly elastic and flexible, making it exceptional at cooling roofs. Its materials are easy to shrink and expand, making it perform well in almost all climates. This leads to longer lasting roofs and lower hydro bills all year round. Acrylic roof coating is arguably the best coating.

#2. Polyurethane Roof Coatings

This roof coating is more rigid and durable than the acrylic coating. More importantly, it is available in two varieties; aliphaltic and aromatic. Aromatic roof coatings are less UV stable and cheaper. For this reason, homeowners prefer coating the base with aromatic and the top with aliphaltic, which is more sunlight resistant.

#3. Silicone Roof Coatings

This type of roof coating works best in extreme sunshine climates. Moreover, it is perfect for spray polyurethane foam roofs. Compared to other types of roof coatings, silicone roof coating weathers best, but it tends to lose its reflectivity over time. If you often walk along your roof, silicone isn’t an ideal choice because it is slicker and easily damaged than the other types of coating.

Summing It Up

Considering the fact that coating will help prolong the lifespan of your roof, it is only wise that you consider this option if you are looking for a permanent solution. In fact, it will make your old roof more appealing without having to replace the entire roofing system. Since coatings cost less than total roof replacement, you will save money in the long run. Coatings they are quick and easy to install, and you can complete application in less than a day without interrupting your schedule.
