How To Measure A Shed Roof For Shingles

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.

How to measure a shed roof for shingles.

Measure the length and width of each portion of the roof multiply length by width for each plane and then add the planes together for the total square footage. Estimating shingles 1 find the square footage of the roof. Measure and mark a 12 foot distance along the floor in the same direction as the pitch of the roof. The base is the bottom edge of the roof while the height is what you measure from the base to the top of the triangle in a straight perpendicular line from the bottom edge of the roof.

As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles. Inches enter the overhang of the gable. Feet inches enter the overhang of the eaves. Finding the size of the roof in squares.

Inches enter the wall to upper pitch start. Enter the length of the building. Before laying down the roof pitch the space it will cover otherwise known as the roofing square needs to be measured. The length measured from the outside of the wall to where the upper.

There are also 29 standard sized shingles measuring 12 inches by 36 inches in each one of these. Enter the attic of the home or any part where the roof framing is visible.

Times number of tabs per foot 7 tabs equals 56 tabs divided by 3 tabs per shingle 3 tabs equals the number of shingles required 19 shingles divide by shingles per bundle 26 shingles bundles required 1 bundle.

So if the base is 5 feet 1 5 m and the height is 4 feet 1 2 m then you re equation would look like this. 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.
