How To Measure Your Roof For Shingles

To figure out your roof s area a simple geometry can be used.

How to measure your roof for shingles.

Measure and record your findings. The pitch of the roof is the rise over a 12 inch run. After this you will need to measure the length of the building from the ground. Your roofer will measure the surface of your roof to determine the total square footage which will dictate how many shingles must be purchased to fully cover the roof s planes.

Climb onto your roof and measure each section by its height and width. The number you get will be an accurate estimate of how much area you have to cover for your roofing project. For example a 4 12 pitch roof that is 100 square feet. Alternatively you can purchase a measuring wheel from your local hardware store.

Roofing is measured in squares. The last step in measuring your roof for shingles is possibly the simplest because all it entails is using your measurements to calculate your roof s square footage. If you use a measuring tape you ll need someone to hold the tape while you measure the area. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.

Record the measurements on your sketch of the roof. Below there is a simple triangle and the math used to work out. But if you re curious how the measuring process works think back to your geometry classes in school. Of course this will be assuming that your home is rectangular.

How to measure a roof for shingles step by step the process of accurately measuring a roof involves first making a diagram of the roof to show the basic shapes of each roof plain and how they relate to one another. The key is to be as accurate as possible since falling short or an overage could mean thousands of dollars when planning your roofing budget. To measure for roofing shingles start by calculating the area of each plane or section of the roof. Required measurements include the following.

For each individual section of roof that you measured you will need to multiply the length by the width which will give you the square footage of that section. 100 1 054 105 4ft 2. Roof pitch area multipliers. If your roof measures 48 feet 15 m x 24 feet 7 3 m multiplying its length by its width would give you a square footage of 1 152 square feet 107 0 m 2.

Use our roof pitch calculator to find the pitch of your roof. Then each measurement is recorded on the diagram applicable to that roof surface.
