Elastomeric Coatings For Roofs
To determine whether an elastomeric coating is right for your roof, you must first consider its lifespan. Though some sources quote even longer lifespans, most elastomeric roof coatings are guaranteed to last for 10 to 20 years. The longevity of an elastomeric coating is highly dependent on the thickness of the coating, the amount of maintenance involved, and many other factors. To get the maximum benefit from an elastomeric roofing system, make sure to hire experienced roofing companies.
There are several kinds of elastomeric roof coatings. Butyl elastomeric is the best choice for flat and low slope roofs. It is compatible with modified bitumen, asphalt built-up, and single-ply applications. Polyurethane elastomeric is best suited for modified bitumen and single-ply applications. Butyl elastomeric may be too thin for some types of roofing.
A good elastomeric roof coating should be able to withstand temperatures of up to a million degrees Fahrenheit. It should also be able to withstand temperatures up to 600°F. Depending on the climate, some elastomeric roof coatings also provide added benefits, such as keeping buildings cooler in hot weather. As long as the application process is done correctly, an elastomeric roof coating should last at least fifteen or twenty years. Proper maintenance is key to ensure that the coating will protect the building, but a reapplying of the coating is required after 15 to 20 years.
An asphalt emulsion is a simple but effective coating. This type of elastomeric roof coating is often used in monolithic foundation membranes to help level irregularities in roof surfaces. It usually requires two to three gallons per hundred square feet of roofing area. Multiple passes may be required to get the best results. This type of roof coating is sensitive to freezing temperatures and is difficult to work in cold weather.
It is vital to prepare a roof before applying an elastomeric roof coating. A professional painting contractor will schedule a site visit and evaluate the condition of the roof. The elastomeric coating will help protect the building and protect the structure. A home improvement store elastomeric roof paint is not intended for roofing applications. It is not recommended for use in the rainy season. If the elastomeric coating is applied improperly, it may cause damage to the structure of the house.
Generally, elastomeric roof coatings are not waterproof. If you have severe roof damage, you should use high-quality elastomeric material. The elastomeric coating should be allowed to dry for at least a day. In ideal weather conditions, it may take up to a week to cure, but in most cases, it will not be affected. If you don’t plan to leave the roof for a month after the application, it will take longer than a week.
A quality elastomeric roof coating is necessary to protect a building from moisture. It should be easy to work with and inexpensive to apply. It is not a good choice for a home that has very irregular surfaces, and it is not suitable for flat roofs. Although it is inexpensive, it is not recommended for home roofs. As it is water-based, elastomeric coatings are susceptible to freezing temperatures and are difficult to apply in cold weather.
Before applying an elastomeric coating to a roof, it is important to prepare the surface properly. A power washer with a 30-degree cleaning tip is best for cleaning the roof. When a power washer is used on a flat roof, it is best to keep it at least 18 inches away from it. Then, you can clean it with a hose. If water remains on the surface, you can use a push broom to push it toward the drain. After the elastomeric coating, you can reinforce the curbs, rooftop equipment, and penetrations.
While elastomeric roof coatings are not ideal for repairing a roof, they can help restore it and make it safer to live in. These coatings are easy to repair and reseal and will last for 10 to 20 years. The process is very time-consuming, but a high-quality finish can make your home more comfortable for you and your family. And if you are not in a hurry, an elastomeric coating can save you time and money in the long run.
