Construction and Materials
TAMKO's roofing coatings are designed to provide a protective and weather-resistant layer for various roofing surfaces. These coatings are formulated to enhance the lifespan of existing roofs, prevent leaks, and offer energy-saving benefits.
The construction of TAMKO roofing coatings typically involves a liquid-applied system. This means the product is applied in a liquid state and cures to form a seamless, monolithic membrane. This method ensures that there are no seams or joints where water can penetrate, offering superior waterproofing.
- Base Material: The primary component of TAMKO roofing coatings is usually a high-quality acrylic or elastomeric polymer. These polymers provide the flexibility and durability required to withstand expansion and contraction caused by temperature changes, as well as environmental stressors.
- Reinforcement: In some applications or specific product lines, reinforcing fabrics (like polyester or fiberglass scrim) may be embedded within the coating layers. This reinforcement adds tensile strength and puncture resistance to the final membrane, creating a more robust system.
- Fillers and Additives: The coatings also contain various fillers and additives to enhance their performance characteristics. These can include:
- Pigments: For color and UV reflectivity.
- Fillers (e.g., calcium carbonate): To add body, strength, and bulk.
- Biocides: To resist mildew and algae growth.
- Fire retardants: To meet building code requirements for fire resistance.
- Flow and leveling agents: To ensure a smooth and even application.
- Curing Process: The coatings cure through the evaporation of water or solvents (depending on the formulation), or through a chemical reaction, forming a continuous, waterproof barrier.
The specific materials and construction can vary depending on the intended application and the type of roofing surface being treated. TAMKO offers coatings for a range of substrates, including:
- Metal roofs
- Single-ply membranes (TPO, PVC, EPDM)
- Built-up roofs (BUR)
- Modified bitumen roofs
- Concrete roofs
- Asphaltic roofs
These coatings are applied using various methods, such as roller, brush, or spray application, allowing for versatility in their use across different roof types and complexities.
