However, one of the most common challenges homeowners face is determining how much paint they’ll need for the job. Buying too little can delay your project while overbuying wastes money and resources. This guide will walk you through the process of accurately calculating the amount of roof painting in Melbourne you’ll need. The first step in calculating your paint needs is to measure your roof’s surface area accurately. For a Simple Pitched Roof Measure the length and width of each roof plane (section). Multiply the length by the width of each plane to get its area. Add the areas of all planes together for the the total roof area. For Complex Roof Designs For roofs with multiple levels or unusual shapes, consider hiring a roofing contractor like West Pro Painting & Decorating for accurate measurements. PAGE 2

3. Account for Roof Pitch The pitch of your roof affects the actual surface area that needs painting. To adjust it, determine your roof’s pitch (rise over run) and use a multiplier based on the pitch: Low pitch (3/12): Multiply area by 1.04 Medium pitch (6/12): Multiply by 1.08 Steep pitch (12/12): Multiply by 1.20 Consider the Paint’s Coverage Rate Paint coverage rates vary depending on the product and roof material. Check the manufacturer’s specifications for the coverage rate per litre. Metal roofs: 100-200 sq ft per litre Tile roofs: 60-100 sq ft per litre Asphalt shingles: 75-150 sq ft per litre W E S T P R O P A I N T I N G . C O M . A U Calculate Base Amount To calculate the base amount of paint needed, divide your total roof area by the paint’s coverage rate. This gives you the number of litres for a single coat. For example: Roof area: 2000 sq ft Coverage rate: 100 sq ft per litre Calculation: 2000 / 100 = 20 litres

4. Factor in Multiple Coats Most roof paintings in Melbourne require at least two coats for adequate coverage and protection. To account for multiple coats: Multiply your base amount by the number of coats you plan to apply. For example: 20 litres x 2 coats = 40 litres Also, consider roof features. Don’t forget to account for extra paint needed for roof features such as chimneys, vents, skylights, and dormers. Measure these separately and add their area to your total calculations.
