How Do You Figure How Much Metal Roofing You Need

The rules governing roofing permits vary among districts.

How do you figure how much metal roofing you need.

Once you have a licensed contractor ready to do your roofing job they need to pull a roofing permit. Enter the diameter of the roof ridge vent gap 1 3 finally enter the coverage area width of the panels you plan to buy. Use our roof pitch calculator to find the pitch of your roof. For example standing seam metal roofing is 24 inches wide.

Let owens corning roofing help you calculate exactly how much ventilation you will need for a healthy and balanced attic with our 4 step ventilation calculator. Step 5 multiply the total width by the total length for the total roof area. Enter square footage calculate or enter the square footage of the attic or area to be vented. Next find the square footage of the metal roofing panels you want to use.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. This is simply 100 square feet of roof. In our example we will use 24 inch standing seam roofing so we will divide 360 inches by 24 which equals 15. Finding the size of the roof in squares.

This will determine the amount of roofing material you need. Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material. We plan to enable the use of fractions at a later time. Divide the length of your roof by the width of the metal.

Measure the length and width in feet then multiply together to find the square footage. Multiply the footprint square footage by the multiplier for your roof pitch to find the actual square footage of the roof. Step 6 divide the total roof area by the width of the metal roofing material you intend to use. 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.

For example if the measured length is 19 feet 10 inches and an additional overlap of 6 inches is required at both ends the final figure will be 21 feet 19 feet 10 inches plus 6 inches times 2. For example the department of economic and community development in daly city requires a permit application to be submitted for any roofing work covering more than 100 square feet. A square simply refers to a 10 x 10 square of roofing. Determine the width of the metal you are installing.

You also need to be sure that you have taken a look at how much more material is needed the types of materials you can use and the way that the installation will be done.
