How Much Metal Roofing Do You Need?: 1 Minute to Calculate Your Metal Roofing Requirements

Are you considering a metal roofing installation? Understanding how much metal roofing you need is crucial for a successful project. Metal roofs are not only durable but are also increasingly popular due to their longevity and energy efficiency. To accurately estimate your requirements, start by calculating the total area of your roof.

Measure Your Roof Area

To find out how much metal roofing you need, measure the length and width of each section of your roof. If your roof has multiple slopes, break down the measurements into manageable sections. Once you have the dimensions, use this formula: Length x Width = Area. For instance, if one section measures 40ft by 20ft, the area would be 800 square feet.

Don’t forget to consider the pitch of your roof. If your roof slopes, you'll need to adjust your measurements. The formula for calculating the area of a sloped roof includes the pitch: Roof Area = (Length x Width) / Cosine(Pitch Angle). This adjustment ensures you're not underestimating the amount of material needed.

Accounting for Overlap and Waste

When ordering metal roofing, it's essential to factor in overlap and waste. Typically, you should add 10% to your total area to cover mistakes, cuts, or overlaps where metal sheets meet. For instance, if your calculated area is 800 square feet, ensure to order for approximately 880 square feet.

Finally, consider the type of metal roofing you want to use. Different styles, such as standing seam or corrugated, may have varying coverage per square foot, impacting your final calculations.
