How to determine shingles needed for roof.

Determine the bundles of shingles. You will then have to get the measurement of the rake of the roof. 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. This roof shingle calculator requires four basic inputs.

Then determine the area of the roof as if it were flat. Measure the length and width of each portion of the roof multiply length by. Roof length measured in feet roof width measured in feet roof pitch roof type either gable or hip. When figuring the amount of shingles needed to roof a house you first convert the total square footage of the roof to squares a square represents 100 square feet of area covered by shingles.

Place the end hook of the tape on the corner and run it all the way to the opposite corner of the house. Measure both the width gable side and the length eave gutter side. They are typically 36 inches long in total. Find the square footage of the roof.

Remember that the length and width need to be found for the roof not the house so take into account that the roof overhangs the building. The first thing you need to do when figuring out how to put shingles on a roof is to determine which type of roofing shingles you need. 3 tab shingles are the most common type of shingle. Architectural shingles are another option and are installed the same way as 3 tab shingles but give your roof.

Measure your roof accurately use a measuring tape preferably 50 or 100 feet long and get exact ground dimensions of your house. Singles are often sold in bundles with three bundles equaling one roof square. Measure the pitch of your roof in the attic. A square of shingles is the quantity needed to cover 100 sq.

Mark a length of 1 foot 0 30 m on a long level starting from one end. The number of squares determines the amount of shingles needed. Hold the end you measured from against the bottom of a rafter so it s sticking straight out horizontally and is level. Given pitch and a horizontal area measurement multiply the horizontal area by a correction factor corresponding to pitch provided in the table below to determine the actual area of the roof to be used in the roofing material calculator.

To do this you need to note that one tab will be equal to 1 foot. Start by measuring the length and width of the roof in feet as you re standing on the ground.
