Roof & Wall Coatings

Roof Coatings

• Roof-coating products seal out moisture and renew surfaces. Many roof coatings are designed to resist mold, rust and fire. When choosing a product, select a formula that's designed for your specific roofing material. Most products that protect against sun and weather damage can be used on tar or gravel.

Cool-Roof Coatings

• Many roof coatings are now designed to reflect the sun. Most of these cool-roof coatings are composed of water-based acrylic elastomers that can be used on metal, asphalt, wood, rubber and bitumen. Select a coating that incorporates water, rust, and mildew protection with solar reflection for best results. Some are based on biomaterials, such as agricultural oils and biobased urethane.

Wall Coatings

• Various wall coatings also work for roofs. These coatings are composed of acrylic or rubber, which makes them elastic. They protect against damage caused by rust, mold, mildew, moss and water. They shield your home from ultraviolet light and storm damage, making them smart home investments.

Application

• Walls and roofs should be entirely dry before applying any coating. Avoid starting the project if it might rain. Clean the roof of debris. Wash the roof and walls with a pressure washer to remove residue, which will ensure good application. Use a drop cloth to protect windows and plants from splatters. Apply the coating with a brush or roller, ensuring even application. Do not allow it to puddle or spread too thinly in areas.
