Measuring A Roof For Shingles From The Ground

Mark a length of 1 foot 0 30 m on a long level starting from one end.

Measuring a roof for shingles from the ground.

The length l times the height h of a triangle is twice its area a2. 1 roof square 100 square feet. A how to measure a roof for shingles from the ground new roofing isn t supposition to the oil. Complete one side at a time before moving on to other areas.

The first technique is referred to as the shingle count method which is used for estimating the measurements of all rectangular shaped sections of a roof. Determine your roof pitch see roofpitch if you need help. We also live in an institution shake. Hold the end you measured from against the bottom of a rafter so it s sticking straight out horizontally and is level.

For square or rectangular roofs you ll only need to record the length and width. This can be done from the ground by taking the measurement of the length of the house and adding the length of the overhangs to it. Take the following steps to measure your roof from the ground. For sloped sectional roofs write down the dimensions of each individual plane.

Go all the way around your house and fill in your outline with your measurements making sure to account for overhang. Multiple the number of shingles times the width of each shingle which you can measure at ground level to get b in the figure below. Then count the number of shingles to the peak of the roof. Extend your tape measure along the outer edges of the roof to find its length and width in feet.

To sum it up each individual tab on a 3 tab shingle measures approximately 12 wide by 6 high. Measure the horizontal run of the roof surface from the ground a in the third figure below. From the 1 ft 0 30 m spot you marked on the level measure upward to the rafter. Use a simple formula to approximate the square footage of triangular areas where two sections of a roof meet at each.

L h 2 area calculating an area of a triangle when estimating a roof. Section off your roof and write your calculations down as shown below dotted lines. If the existing shingles are standard 3 tab shingles you can get this measurement by taking note of the number of tabs along the eaves and ridges then determine the length in feet. Make a outline of your roof on paper.

So if you divide your answer of a product of length times height by two you will get the area of a triangle.
