Are you looking to give your roof a fresh new look? Perhaps you want to protect it from the harsh elements or increase its energy efficiency. 

Whatever your reasons may be, roof painting is an excellent option that can transform the appearance and performance of your roof. In this comprehensive guide, we will explore the best types of roof paints available and provide valuable tips for choosing the right colour to suit your needs.

Why Consider Roof Painting?

Your roof is constantly exposed to various weather conditions, including intense UV rays, heavy rainfall, and corrosive pollution. Over time, this exposure can lead to degradation and ageing of your roof, compromising its durability and appearance. Roof painting offers a range of benefits that can significantly improve the lifespan and aesthetics of your roof:

  • Enhanced Durability: A high-quality roof paint can add years of durability to your roof, protecting it from UV damage, corrosion, and premature colour fading.
  • Increased Energy Efficiency: Certain roof paints are designed to reflect heat, improving the thermal performance of your roof and reducing cooling costs during hot summers.
  • Improved Appearance: Roof painting can transform the look of your entire house, giving it a fresh, updated appearance and increasing its curb appeal.
  • Protection Against Mould and Algae: Some roof coatings have mould and dirt resistance properties, preventing the growth of mould, algae, and other organic matter on your roof.
  • Choice of colours: Roof paints come in a wide range of colours, allowing you to choose the perfect shade that complements your home’s exterior.

Types of Roof Paints

When it comes to roof painting, there are several types of paints available, each with its own unique properties and suitability for different roof materials. Let’s explore the most common types of roof paints:

Acrylic Coatings

Acrylic coatings are versatile and can be used on various roof membrane surfaces, including metal roofs and single-ply membranes. These coatings offer excellent resistance to UV radiation and hail damage, making them ideal for withstanding harsh weather conditions. Acrylic paints also provide a significant reduction in surface temperature when exposed to direct sunlight, helping to keep your home cooler in the summer. They are cost-effective, easy to work with, and available in a wide range of colours.

However, it’s important to note that acrylic coatings can lose mil-thickness over time due to weathering and are not suitable for roofs that experience ponding water. Additionally, they require application in temperatures above 50 degrees Fahrenheit to ensure proper curing.

Silicone Coatings

Silicone coatings have gained popularity in recent years due to their ability to withstand long-term exposure to ponding water. These coatings offer excellent adhesion and weather resistance, making them a durable choice for various roof surfaces. Silicone paints provide high reflectivity and emissivity ratings, helping to keep your roof cool and reducing energy costs. However, they can hold dirt on the surface and may lose reflectivity over time.

Silicone coatings are available in different colours but tend to be more expensive than other types of roof paints. Additionally, there are limited options for materials that can be applied directly to a silicone surface.

Polyurethane Coatings

Polyurethane coatings are commonly used on sprayed-in-place foam roofs but can also be applied to other existing roof membranes. These coatings offer excellent impact resistance and can withstand foot traffic. There are two types of polyurethane coatings: aromatic and aliphatic. The base coat is durable but lacks high UV resistance, while the aliphatic topcoat provides UV stability, colour retention, and cleanliness.

Polyurethane coatings provide flexibility and can be an effective solution for extending the lifespan of your roof. However, they require proper application and may be more expensive than other options.

Asphaltic Rubber Membrane System

The asphaltic rubber membrane system is a cold-process fluid-applied material that can extend the service life of your existing roof. This system combines the elasticity of rubber with the waterproof and weatherproof properties of emulsified asphalt. It forms a fully adhered monolithic membrane that provides instant waterproofing and weatherproofing capabilities.

The asphaltic rubber membrane system is an economical repair solution, but it requires proper preparation and application. It can be applied in various thicknesses to suit your specific needs.

Choosing the Right Roof Paint Colour

Now that you’re familiar with the different types of roof paints, it’s time to choose the right colour for your roof. The colour you select can have a significant impact on your home’s overall appearance and curb appeal. Here are some tips to help you make the right choice:

  • Consider Your Home’s Style: Take into account the architectural style and colour scheme of your home. Choose a roof paint colour that complements the existing elements and enhances the overall aesthetics.
  • Think about Climate: Consider the climate in your area. Lighter colours reflect heat and are suitable for hot climates, while darker shades can help retain heat in colder regions.
  • Neutrals are Timeless: Neutrals like blacks, browns, greys, and bronzes offer versatility and allow for a wide range of exterior paint colour choices.
  • Avoid Strong Undertones: Opt for colours with neutral or subtle warm undertones to ensure compatibility with various exterior paint colours.
  • Consider the Roof Material: Different roof materials may require specific colour choices to achieve a natural appearance. Earthy colours work well for tile roofs, while blacks and charcoals are suitable for asphalt shingles.

It’s essential to test the selected colour on a small section of your roof before fully committing to ensure it meets your expectations.

Hiring Professionals vs. DIY

Deciding whether to hire professionals or tackle the roof painting project yourself depends on several factors. While DIY painting may save you money, professional painters have the expertise and proper tools to ensure a high-quality, long-lasting finish. They also possess the necessary safety equipment for working at heights. If you choose to paint your roof yourself, here are some essential tips:

  • Clean the Roof: Use a pressure washer to thoroughly clean the roof before painting. Remove any dirt, debris, or loose material that may affect the adhesion of the paint.
  • Repair Damages: Address any roof damages before painting. Fix leaks, replace broken tiles, and ensure the surface is smooth and in good condition.
  • Primer Application: Apply a primer to promote paint adhesion and prevent rust or mildew formation. Follow the manufacturer’s instructions for the appropriate primer type and application method.
  • Choose the Right Tools: Select the right tools for the job, such as a paint sprayer or a soft-bristled broom for larger surfaces. Use high-quality paint brushes for detailed areas.
  • Weather Conditions: Choose a day with favourable weather conditions for painting. Avoid painting in freezing temperatures or during periods of rain or high humidity.


Roof painting offers an excellent solution for enhancing the durability, energy efficiency, and overall appearance of your roof. By selecting the right type of paint and colour, you can transform your home’s exterior and increase its curb appeal. Whether you decide to hire professionals or embark on a DIY project, proper preparation, application, and maintenance are key to achieving a long-lasting and visually appealing result. Take the time to research and choose the best roof paint for your specific needs, and enjoy the benefits of a beautifully painted roof for years to come.
