How do I calculate my roof space?

As part of home maintenance or renovation, knowing how to estimate roof space accurately is of utmost importance. Knowing its dimensions allows for informed choices when considering insulation upgrades, additional storage needs, or solar panel installations. Therefore, many people asked: How do I calculate my roof space? – Here is an easy guide on estimating roof area!

Why Is Roof Space Necessary?

Roofspace, commonly referred to as attic space or loft space, serves a multitude of uses from storing items to optimizing energy usage efficiency. Understanding its precise dimensions enables you to make full use of its potential.

Step One: Determine Roof Length

Step one is taking measurements of how long your roof is. Measure from top to bottom using a tape measure so you have an exact reading.

Tips: For accurate measurements on multiple sections of the roof, divide each into smaller segments and measure individually to get more precise measurements.

Step Two: Determine Roof Width

Next, measure the length of your roof. Take measurements across its entire width – one end to another side of your structure – making sure to take accurate readings for best results.

Tip: For pitched roofs, take care to measure at their widest point to get an accurate reading.

Step Three: Determine The Roof Slope

Roof pitches or slopes have the power to significantly impact available space within your home or workplace. Roofs that have a steeper slope tend to be less functional space inside the attic however, roofs with a more gentle slope provide more space.

Tip: You can use the level as well as a tape measure. Place the level on the roof’s underside and take a measurement of the vertical rise in a horizontal distance. The result will reveal an estimate of the slope.

Step Four: Calculate the Area of Your Roof

It’s time to estimate the size of the roof. Multiply the width and length of your roof. If your roof measures 30-foot long with a width of 25-foot the total area is 775 square feet.

Formula:

Area = Length x Width

Step Five: Consider the Slope for Adjustments

If your roof is on a slope, you’ll have to alter the calculation of area. The steeper the slope, the more the roof’s surface will be. To adjust, divide your area with the slope coefficient. For instance, for a roof with a pitch of 6:12, you’ll need to divide your size by 1.2 to accommodate the additional space.

Adjusted Formula: 

Adjusted Area = Area x Slope Factor

Step Six: Calculate the Usable Roof Space

To determine the usable space take out any spaces that are blocked or not usable such as corners with slopes or areas occupied with roof beams. These spaces may not be suitable for storage or other purposes.

Tips: If you plan to use the roof space for storage or for other reasons ensure that the space conforms to standards for accessibility and safety.
