How much shingles do i need for my roof.

Roof surfaces are measured in squares a square is an area of roof which measures 100 square feet. High wind areas and other types of shingles may need more. Keep in mind that a drip edge will be needed to protect the edge of the roof from rot vents and other materials such as flashing or caulk. You will then have to get the measurement of the rake of the roof.

For example a very steep roof on a 1 000 square foot attic will need more shingles than a lower sloped roof on the same sized attic. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. To do this you need to note that one tab will be equal to 1 foot. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.

Note that in the last 3 4 years costs of roof shingles and many accessories have gone down by an average of 18 20 currently the us national average for benchmark architectural shingles is around 74 51 square or 25 per bundle. Waste is calculated at 7 5 for a gable roof and 15 for a hip roof which are typical in the roofing industry. However shingles are packaged in a way that they are light enough for the average person to carry around. 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.
