Roof coatings on flat roofs as they are known, involve applying a fluid roofing membrane over an existing roof substrate. It’s rolled on evenly over the roof making a waterproof, durable, and seamless layer. These coatings protect your home from roof leaks, are energy efficient, reduce cooling costs, and extend the service life of your roof.
Roof coating is a barrier between your flat roof and the elements. It protects your roofing system from UV rays and rain damage. It also prevents algae and mold growth as well as makes your roof more resistant to fire. These coatings have a thicker consistency than paint and are tremendously elastic because of the high-quality resin that they contain. This elasticity makes the coating flexible and pliable to fill in seams and small racks. Typical roof coatings are made of silicone or acrylic.
Benefits of Roof Coating-Types of Roofs
There are many benefits to roof coatings. First, they are the least expensive, most effective way to help make flat roof structures become more energy efficient. Buildings that have roof coatings are much easier to control the temperature inside. They also produce less strain on HVAC systems because the coatings reflective and emissive benefits help reduce energy use. They also prevent chemical damage as well as physical or water damage. Roof coatings can increase your roof’s life by several years, and there is always the option to re-coat your roof.
Many suggest using silicone for flat roof such a Gaco S-2000 Roof Coating. One of the primary reasons is because its resistant to the standing water that tends to gather on flat roofs. Silicone doesn’t absorb water like some of the acrylic-based coatings because they are naturally resistant to water and dampness. It also doesn’t shed over time or require reinforcing with fabric. This saves time and money on extra labor. A little goes a long way, so you use less of this material than acrylic coatings.
For concrete roofs, the best choice of roof coating system is a silicone one such as Acrylic or Urethane based Elastomeric Roof Coatings. This solution is seamless and water-based to protect roofs from problems with leaking and rusting. Since it is very reflective, it helps reduce temperatures on rooftops.
Any of the coatings covered can be used on your flat roofs surface, it’s just that some work better than others. The key is to contact a roofing professional who can give you the best advice on which coating to pick for your roof. Roof coatings can be very beneficial and are worth the investment in most cases.
