The answer depends on several factors, including the type of coating, the roof’s texture and condition, as well as the manufacturer’s specifications. On average, a 5-gallon container of roof coating will typically cover between 250 to 350 square feet in a single coat. For more porous or rough surfaces, coverage may decrease, while smooth, clean surfaces often allow you to maximize the product’s spread. Always check the instructions on your chosen roof coating, as some may specify different rates—but as a general rule, budgeting for approximately 300 square feet is a safe bet for one coat.As a designer, I always recommend taking into account both the practical and aesthetic aspects of any surface upgrade. Beyond ensuring your roof is structurally sound and protected, consider how the finish will complement your home’s external design. If you're looking to visualize and plan your upgrades for different parts of the house efficiently, leveraging tools like a home designer platform can dramatically streamline your workflow.Tips 1:Before you begin applying roof coating, thoroughly clean and inspect your roof.
