When choosing the best roof paint for coating a flat roof or gutter the most crucial factors to consider are waterproofing capability, UV protection and durability.
It may be tempting to choose a roof paint which is cheap and easy to apply, however this is not likely to give you the results you require for lasting protection for your roof, especially on a flat roof.
Saving a small amount on the cost of a roof paint may end up costing you a lot more in the medium to long term.
An acrylic roof paint is a cheaper and easier solution to coating your roof; however it requires more frequent maintenance and reapplication. While acrylic paints are generally a popular choice for sloping metal roofs they are usually not recommended for flat roofs due to their susceptibility to damage from ponding water. An acrylic paint will degrade when exposed to prolonged standing water.
Acrylic roof paints offer good UV resistance, but they may degrade faster when exposed to prolonged sunlight. They can also become brittle with age in harsh climates.
When selecting the best roof paint, you should look for a paint with a long warranty from a reputable manufacturer. If you are painting a flat roof, you should ensure that the roof paint is recommended, and covered by the manufacturer’s warranty, for this purpose. It’s also a good idea to check out online reviews about the product you are considering.
Silicone roof paints are known for their durability and resilience to weathering, UV rays and temperature fluctuations. A quality silicone roof coating will maintain its elasticity over time and will not crack.
Additionally, a silicone roof paint is applied in thick layers which help to fill cracks and gaps in the roof surface.
A silicone roof paint will usually be more expensive initially than an acrylic roof paint however the durability and long lifespan of the silicone will result not only in a more waterproof coating but a cheaper alternative over time.
