With that as background you are now ready to estimate how many shingles you will purchase for your roof project.
How to measure a shed roof for shingles.
To do this you need to note that one tab will be equal to 1 foot.
Total length of the roof ridge is 96 in.
Before laying down the roof pitch the space it will cover otherwise known as the roofing square needs to be measured.
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.
There are also 29 standard sized shingles measuring 12 inches by 36 inches in each one of these.
This is simply 100 square feet of roof.
Enter the length of the building.
Estimating shingles 1 find the square footage of the roof.
Finding the size of the roof in squares.
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.
The length measured from the outside of the wall to where the upper.
5 feet 1 5 m x 4 feet 1 2 m 2 10 square feet 0 93 m 2.
Roofing contractors estimate projects and materials by the square so it is crucial to find this measurement to accurately estimate the amount of material needed.
You will then have to get the measurement of the rake of the roof.
Measure and mark a 12 foot distance along the floor in the same direction as the pitch of the roof.
Inches enter the overhang of the gable.
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.
Inches enter the wall to upper pitch start.
A square simply refers to a 10 x 10 square of roofing.
Now we need to calculate the shingles required for the ridge cap.
Waste is calculated at 7 5 for a gable roof and 15 for a hip roof which are typical in the roofing industry.
Enter the attic of the home or any part where the roof framing is visible.
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.
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.
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.
