Elastomeric roof coatings can provide a cost-effective alternative to a full roof replacement. When a roof shows signs of wear, damage, or leaks, many people assume they have to go through the expensive process of replacing the entire structure. However, using elastomeric coatings can add up to 20 years to the lifespan of the roof while solving common roofing problems. The material cost for elastomeric roof coatings is often significantly less than that for a full roof replacement, and because they can be applied directly over the existing roof, there are savings in labor costs reduced waste, and occupant inconvenience. In addition, these white coatings can also provide energy efficiency benefits by reflecting sunlight, potentially lowering cooling costs. Given the considerable savings in materials, labor, and energy, elastomeric roof coatings often represent a wise financial choice for those looking to maintain the integrity and function of their roof.
Elastomeric roof coatings offer excellent protection for your roof, potentially extending its lifespan by up to twenty years. The most common types of elastomeric roof coatings are silicone, asphalt, polyurethane, and acrylic. These coatings are typically applied using a roller or spray method, with several gallons used per 100 square feet to ensure thorough sealing. It's important to note that elastomeric roof coatings are not the same as paint. While both are liquids, there are significant differences between them.
Elastomeric roof coatings are superior to paint for several reasons:
Elastomeric roof coatings can be applied to various types of roofing materials. However, some preparation work is necessary to ensure optimal effectiveness. Before applying an elastomeric coating, the roof should be thoroughly cleaned. Additionally, a comprehensive inspection should be carried out to identify any existing damage. It's essential to address significant repairs before relying solely on roof coatings for protection. Concrete, masonry, gypsum, block, brick, and metal surfaces require a coat of primer before the roof coating is applied. The roof must be completely clean and dry prior to applying the primer. Consulting an expert may be necessary to determine the most suitable type of primer for the specific project and roof substrate.
Silicone Roof Coatings Silicone roof coatings provide numerous advantages, including 100% waterproofing, long-lasting durability, and minimal maintenance requirements. Silicone is highly resistant to the elements, effectively preventing UV damage and maintaining waterproofing properties. With its quick curing time, silicone coatings are well-suited for application just before severe weather conditions.
Silicone roof coatings are suitable for various surfaces, including:
Silicone coatings are the ideal choice when:
Acrylic Roof Coatings Acrylic roof coatings exhibit exceptional durability and provide high UV stability. They are highly flexible, making them a preferred option for buildings located in low-temperature environments.
Acrylic roof coatings can be used on the following materials:
Acrylic coatings are the best choice when:
Rubber Roof Coatings Also fall into the acrylic category but differ in a few notable ways. Liquid rubber roof coatings are ideal for metal roofs, as they can be applied over mildly rusty surfaces. They require fewer coats compared to acrylic paints.
SEBS Roof Coatings Styrene Ethylbutlyene Styrene (SEBS) Coatings are specifically designed for metal roofs. These coatings offer a highly reflective surface, helping to maintain a comfortable temperature inside the building while providing maximum protection against UV rays. SEBS roof coatings are waterproof, capable of accommodating building movement, possess high tensile strength to withstand roof traffic, and are made with antioxidants and light stabilizers to prolong the lifespan of the roof. They are particularly suitable for use on rusty metal roofs, effectively preventing corrosion.
SEBS coatings are the best choice when
EPDM Roof Coatings EPDM roofs are highly durable and suitable for areas with severe weather conditions. However, they are not easily compatible with solvents used in roof coatings, as the solvents can cause the EPDM to swell. Coating an EPDM roof is still possible but requires careful selection of solvents. Consulting a professional roof coatings installer can help in choosing the appropriate solvent.
TPO Roof Coatings TPO membranes have low surface energy, which makes it challenging for roof coatings to adhere properly without prior treatment. To ensure long-lasting performance of the roof coating, it is advisable to sand down the TPO surface and apply a suitable primer before coating.
Asphalt and Modified Bitumen Roof Coatings Applying roof coatings to asphalt or modified bitumen roofs require special care. New bitumen and asphalt roofs should age for a minimum of ninety days to allow excess oil to dry off before applying primer and/or roof coating. While older asphalt or bitumen roofs have less retained oil than new ones, they still have some. To prevent oil stains on the roof coating, applying a stain blocker before coating is necessary.
PVC Roof Coatings PVC roofs are naturally rigid, posing challenges when coating a new PVC roof. If you have a PVC roof, it is important to allow it to age before applying either a silicone or acrylic coating.
Metal Roof Coatings For metal roofs, it is crucial to ensure that the roof is in good repair to ensure worker safety and the effectiveness of the coating. If your metal roof has mild rust, applying acrylics or silicones before the coating process is recommended. Alternatively, a SEBS coating can be used without prior treatment for rust, unless the roof has severe rusting. Keep in mind that fiberglass skylights can pose hazards to workers. To prevent accidents in the future, ensure that the skylight is not painted the same color as the roof.
