Roof coating is a necessity for residential, commercial and industrial buildings. It extends the lifespan of a roof by preventing water, chemical and physical damage. The simple solution offers a host of benefits, acting as both a protective measure against high and low temperatures and extending the longevity and functionality of your roof. It protects your roof against harsh weather and environmental conditions, saving money for the building owner.
How Roof Coating Works
Acrylic polymers are most commonly used for roof coatings as they have been specifically designed to weather the harsh conditions that a roof faces. The coating looks like paint in a can, but is made up of a very different, thicker material. It is resistant to ponding (collecting) water, has reflectivity properties and has the ability to expand or contract. It is usually white in color – which reduces the temperature of the roof membrane and also reflects the heat portion of sunlight.
Almost all types of roofs can be coated, extending the lifespan of your roof in a number of ways while improving the aesthetic. The coating is applied by using a spray, roller or brush, and is usually applied in colder weather, and when no rain is forecast in order for it to set properly. The time it takes for the coating to dry depends on the air temperature and moisture in the air, as well as the type of coating used. A roofing professional can determine what roof coating will suit your roof best, as well as whether or not you need a primer – a decision that is based on the type of coat used as well as the conditions that the roof will typically handle. The professional will also determine how much coating is required.
Things to Know Before Coating Your Roof
After consulting with a roof professional and determining what type of coating works for your roof, you’ll need to prepare the roof surface. In order to do so, it must be thoroughly cleaned and allowed to dry properly. All debris must be cleared, and any noticeable problems should be fixed before the coat is applied. This is a vital step to ensure that the coating application is successful.
Benefits of Roof Coating
Applying a roof coating is the smartest thing you can do for your roof. It is best to apply to the roof coating when the roof is new or relatively new, as it will have fewer problems than an older roof. However, if any faults are fixed prior to the coating, the roof being new is not a prerequisite. Below are the advantages that roof coating provides:
- It reduces heat transfer into the building, decreasing expansion and contraction – also known as thermal shock. This keeps the roof in much better condition.
- Helps stop minor leaks. The coating will stop any little leaks from spreading, however the roof should be properly repaired and repaired prior to coating application, and any big problems should be addressed beforehand.
- Reflective coatings can also significantly reduce heat energy costs – depending on your geographic location and insulation. The coating allows heat to be stored, while regulating the temperature. This decreases the risk of power outages and the strain on the electrical grid.
- Roof coating makes the roof resistant to ultraviolet radiation from sunlight and other adverse effects of weathering.
- It acts as waterproofing protection for the roof, keeping the interior dry and reducing the chances of flooding and/or water damage.
Roof coating – if done properly – typically lasts up to 10 years or more. Performance is based on type and conditions, as well as coating film thickness. It is recommended that you inspect your roof at least twice a year, paying attention to how effective the coating is. Your roof can be recoated once the coating wears away as most coatings are renewable.
