Making the correct choice for your roof paint is essential for extending its life and shielding it from adverse weather. Owners have to decide based on their needs which is better: oil-based or water-based roof paints, as both types have their advantages. Through the following article, you will be able to understand which type of roof paint is best for you.
Roof Coating and Roof Painting
Roof coating and roof painting are similar processes that involve the use of paint or coating to enhance the strength of a roof. Roof coating paint provides protection and prevents water infiltration and damage, UV rays, and weathering. With roof painting, there are extra advantages, including beautification, efficiency, and even longevity of the roof. The type of paint—oil or water-based—depends on the price range, appearance, and climate.
What are Oil-Based Roof Paints?
Alkyd paints, also known as oil paints, are popular for their toughness and hard, glossy finish. It includes natural oils such as linseed or synthetic ones that, when they dry, form a hard and water-resistant film. Roof paints made from oils are known to have long durability and excellent adhesion capabilities.

Pros of Oil-Based Roof Paints
- Durability: The oil-based paints are more durable and can withstand heavy usage and therefore are suitable for areas that have more traffic or areas that are exposed to harsh weather conditions. They are not easily affected by weather conditions such as rain, heat, sunburn, and wind.
- Water Resistance: Organic solvent-based coatings provide long-lasting protection against water penetration and moisture intrusion.
- Enhanced Finish: These paints provide a luxurious, shiny surface and enhance the looks of your roof.
- Slow Drying Time: It dries slowly, and this gives time to correct mistakes or level the paint on the surface before it dries up.
Cons of Oil-Based Roof Paints
- Long Drying Time: As the paints dry slowly, the curing of oil-based roof paints takes a longer time as compared to the curing of water-based roof paint.
- Odour and Emissions: Oil-based paints have what is known as VOCs, volatile organic compounds that produce fumes that are dangerous if there is no proper air circulation.
- Complex Cleanup: To clean brushes and other tools after painting with oil-based paints, paint thinner or mineral spirits are needed, which is expensive and cumbersome.
- Environmental Impact: Oil-based paints contain high VOCs that cause pollution of the air and may cause health complications.
Water-Based Roof Paints
Washing paints, also called latex or acrylic paints, are made with water as the baseline solvent. These paints are usually popular amongst the owners who pay attention to the ecological impact as they contain few VOCs. Recent innovations in technology enhance water-based paints to be as tough as oil-based paints and therefore are ideal for roof coating.
Pros of Water-Based Roof Paints
- Environmentally Friendly: Water-based roof paints release fewer VOCs, reducing air pollution and the impact on human health.
- Quick Drying: water-based paints take less time to dry up, and therefore, there is little time between the application of two coats, and the entire process is completed much more quickly.
- Low Odour: These paints are almost odourless and therefore more comfortable when applied in closed spaces.
- Easy Cleanup: Because water is the main solvent, cleaning tools are as basic as washing them with soap and water.
Cons of Water-Based Roof Paints
- Less Durable in Extreme Conditions: New water-based paints are more or less equal performance with oil-based paints but may not be as effective when exposed to very hot, sunny, and rainy weather.
- Possible Peeling and Cracking: Water-based roof paints can at times peel or crack, especially in regions that have high humidity, especially if the work was not well done.
- Cost: The initial cost of water-based roof paints is almost equal to that of oil-based paints; however, the latter may need more frequent touch-ups, thus increasing the overall maintenance cost.
Oil-Based or Water-Based Roof Paint
When selecting the ideal roof paint, consider the following factors:
-
Durability and Longevity
The oil-based roof coating is more resistant and appropriate for surfaces that are subjected to various weather conditions. It offers a hard-wearing and waterproof barrier that can be renewed without being touched up for several years at a time.
Water-based paints have advanced in their VOC content and resistance to wear and tear but may still need to be reapplied more frequently in highly demanding areas.
-
Application and Drying Time
The water-based roof paints are faster in drying than the oil-based roof paints and are therefore recommended for use where time is of the essence. Although they last longer, oil-based paints take a longer time to dry than their water-based counterparts.
If you are operating from a region of fluctuating climate conditions, then water-based paints might just be the best because they will not be as affected when the climate changes and they are less likely to be damaged during the drying period.
-
Environment and Safety Consideration
Looking at the environmental considerations, water-based paints are the clear winner. They have lower levels of VOCs as they are safer for homeowners and the environment as well. Oil-based roof paints give off strong vapours and need chemicals to clean up, and this leads to pollution of the air.
-
Colour Retention and Finish
The oil-based paints are known to offer a shinier and more luxurious look and last longer, especially when it comes to fading off the colour due to UV radiation. There are vibrant colours of water-based roof paints too, but they may not have the shine for longer times, especially when exposed to direct sunlight.
Considerations to make when Selecting Roof Paint
The decision on which kind of roof coating to use is influenced by climatic conditions and weather patterns, the need for appearance, and the durability of paints. Severe weather is likely to work in the favour of oil-based paints due to their endurance, and mild climates are likely to prefer water-based paints due to their environmental impact. Oil-based paints give a shiny appearance, whereas water-based paints can be of any finish but not shiny.
Oil-based paints cost more at the material buy but will serve longer than water-based paints, which cost cheaper but might require more coating. These are better for the environmentally conscious homeowner since they have less of an impact on the environment and release fewer toxic fumes than oil-based paints.
Roof Coating: Top Professional Recommendations
To achieve a professional-quality roof paint finish, follow these tips:
- First, clean the roof before applying paint.
- Ensure you use the correct primer for the type of paint that you are going to use.
- Use a day with no rain and mild temperature for the paint to dry.
- It is better to apply several thin coats rather than one thick coat.
- Always check regularly for signs of wear and paint the affected areas.

Conclusion
The decision to use oil-based or water-based roof paint depends on what you want and what your roof requires. Oil-based roof coatings are recommended for regions with severe climate conditions because they are more durable and waterproof. However, they present themselves as environmentally unfriendly and also take a longer time to dry. As for the water-based roof paints, these are eco-friendly; they dry up very fast, and also, when one is done painting, cleaning is very easy since they are not affected by the weather, hence very suitable for places with moderate weather.
