Roof coatings play a crucial role in protecting your home from the elements and extending the lifespan of your roof. With so many options available in the market, choosing the right roof coating can be overwhelming. In this comprehensive guide, we will walk you through the different types of roof coatings and help you make an informed decision that suits your specific needs and preferences.

Understanding Roof Coatings

Roof coatings are liquid applied materials that provide an additional layer of protection to your roof. They are designed to enhance the durability, waterproofing, and energy efficiency of your roof. Roof coatings can be used on various types of roofs, including metal, asphalt, concrete, and single-ply membranes.

Types of Roof Coatings

There are several types of roof coatings available, each with its unique properties and benefits. Let’s explore the most common types of roof coatings:

Acrylic Coatings

Acrylic coatings are one of the most popular choices for roof protection. They are formulated from acrylic polymers and offer excellent resistance to UV radiation and hail damage. Acrylic coatings are available in a variety of colours and provide high reflectivity, reducing surface temperature and lowering energy costs. They are also cost-effective and easy to work with. However, acrylic coatings may lose thickness over time and cannot withstand ponding water.

Silicone Coatings

Silicone coatings are known for their exceptional durability and weather resistance. They provide excellent protection against UV radiation and can withstand extreme temperatures and harsh environments. Silicone coatings are highly elastic and can retain their flexibility over time. They are also resistant to oxidation and have high reflectivity and emissivity ratings. However, silicone coatings can be more expensive compared to other options and may require specific application requirements.

Polyurethane Coatings

Polyurethane coatings are commonly used on sprayed-in-place foam roofs but can also be applied to various existing roof membranes. They offer excellent impact resistance and can withstand foot traffic. Polyurethane coatings come in two types: aromatic and aliphatic. Aromatic coatings are durable but do not offer high UV resistance. Aliphatic coatings, on the other hand, are UV stable, retain colour longer, and provide better UV protection. Polyurethane coatings require proper base coat and topcoat application for optimal performance.

Asphaltic Rubber Membrane Systems

Asphaltic rubber membrane systems are ideal for extending the service life of existing roofs. They consist of a highly refined emulsified asphalt combined with elastic rubber properties. These systems form a seamless and fully adhered monolithic membrane, providing instant waterproofing and weatherproofing capabilities. Asphaltic rubber membrane systems can be applied in a range of thicknesses and are cost-effective alternatives for roof repairs.

Factors to Consider

When choosing a roof coating for your home, it’s essential to consider several factors to ensure you make the right decision. Here are some key factors to keep in mind:

Roof Type and Condition

The type and condition of your roof play a crucial role in determining the most suitable roof coating. Different roof materials may require specific coating types and application methods. Additionally, if your roof has existing damage or leaks, it’s important to address those issues before applying a coating.

Climate and Environmental Factors

Consider the climate and environmental conditions in your area. If you live in a region with extreme temperatures, high humidity, or frequent rainfall, you’ll need a roof coating that can withstand these conditions. Certain coatings, such as silicone, are more resistant to ponding water, making them ideal for areas with heavy rain.

Energy Efficiency

Roof coatings can significantly impact the energy efficiency of your home. Look for coatings with high reflectivity and emissivity ratings, as they can help reduce heat transfer and lower cooling costs. Energy-efficient roof coatings are especially beneficial in hot climates.

Longevity and Warranty

Evaluate the expected lifespan of the roof coating and check if it comes with a warranty. A longer warranty period indicates the manufacturer’s confidence in the product’s durability. Be sure to review the warranty terms and conditions to understand any limitations or required maintenance.


Consider your budget when selecting a roof coating. Different coatings vary in price, and it’s important to find a balance between cost and quality. Keep in mind that investing in a high-quality roof coating can save you money in the long run by extending the lifespan of your roof and reducing energy costs.

Finding a Reliable Roofing Contractor

To ensure a successful roof coating application, it’s crucial to hire a reputable and experienced roofing contractor. Here are some tips for finding a reliable contractor:

Research and Referrals

Do thorough research and ask for referrals from friends, family, or neighbours who have recently had roof coatings installed. Look for contractors with positive reviews, certifications, and a proven track record of quality work.

Licensing and Insurance

Verify that the contractor holds the necessary licences and insurance coverage. This protects you from liability in case of accidents or damages during the project.

Experience and Expertise

Choose a contractor with extensive experience in roof coating applications. They should have in-depth knowledge of different coating types, application techniques, and industry best practices.

Written Estimates and Contracts

Obtain written estimates from multiple contractors and compare them. Ensure that the estimates include detailed information about the scope of work, materials, costs, and project timeline. Once you’ve selected a contractor, sign a written contract that outlines all the agreed-upon terms and conditions.

Maintenance and Long-Term Care

Proper maintenance is crucial for maximising the lifespan and performance of your roof coating. Here are some maintenance tips to follow:

Regular Inspections

Regularly inspect your roof coating for any signs of damage, wear, or deterioration. Look for cracks, blisters, or areas with reduced reflectivity. Address any issues promptly to prevent further damage.


Clean your roof coating periodically to remove dirt, debris, and organic growth. Use a mild detergent and a soft-bristle brush or a low-pressure washer. Avoid using abrasive materials or harsh chemicals that can damage the coating.

Preventive Measures

Take preventive measures to protect your roof coating. Trim overhanging tree branches to prevent debris accumulation and potential damage during storms. Avoid walking on the roof unless necessary and use caution when accessing rooftop equipment.

Professional Inspections

Schedule regular inspections by a professional roofing contractor. They can identify any hidden issues, perform necessary repairs, and provide expert advice on maintaining your roof coating.


Choosing the right roof coating for your home is essential for protecting your investment and ensuring the longevity of your roof. Consider factors such as roof type, climate, energy efficiency, and budget when selecting a coating. Follow proper application and maintenance practices to maximise the performance and lifespan of your roof coating.
