Step 1.
Measuring a roof for metal.
If the roof has a triangular shape stretch your tape measure along the bottom edge then measure from the peak point down to the center of the bottom edge.
1 roof square 100 square feet.
For example standing seam metal roofing is 24 inches wide.
If the pitch of the roof is not that steep you won t have to worry too much about following.
The many complexities of a roof must be taken into consideration in order to ensure your numbers add up.
Measuring for a metal roof begins with getting a ladder.
Measure the length of your roof.
Make your next roof your last.
Outline the roof at the points that are on the same level or elevation to ensure that you re getting an accurate calculation of your roofing measurements.
Remember it doesn t have to be to scale or look pretty.
You should do this with someone that can hold one end of the tape measure so you can go to the other ends.
Enter the diameter of the roof ridge vent gap 1 3 finally enter the coverage area width of the panels you plan to buy.

Determine the width of the metal you are installing.
How to figure how much metal roofing you need step 1.
Measuring for a metal roof.
For instance a 38 panel will have an effective coverage width of 36.
So if you divide your answer of a product of length times height by two you will get the area of a triangle.
This is done by measuring from one outside edge of your roof to the opposite.
You will need to go up on top.
We need to know the roof pitch or the slope of the roof.
If you were to click on the peaks it wouldn t give you an accurate reading of your measurement.
The length l times the height h of a triangle is twice its area a2.
Then calculate the pitch of the roof by placing a level against it angling the level so the bubble is centered and measuring the distance between the end of the level and the roof.
For trapezoidal roofs measure the bottom edge the top edge also known as the ridge and the distance between the 2 edges.
Roughly draw out your roof on a piece of paper.
The metal roof length calculator calculates the distance from peak to trim so add the length you want the roof metal to extend beyond the eave trim.
Thus in a simple style house you ll only have to click on the corners.
Find the dimensions of each of the roof s faces.
