Point Count Roofing Materials

All you have to do is to multiply the factors below with your computed total area in square meter.

Point count roofing materials.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. To estimate roofing materials start by finding the total square footage of the roof and divide the number by 100 to determine the number of squares in the roof. Roofing materials for pitched roofs include the following. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square.

Even steeper are many mansard roofs and parts of gambrel roofs such as on barns which may have 20 in 12 pitches. Pitched or sloped roofs range from a moderately sloped 3 in 12 pitch to the 45 degree angle 12 in 12 slope commonly seen on a frame roofs. Typical materials that are candidates for point count analysis include drywall joint compound ceiling or wall texture hard plaster etc. All in straight to the point calculations.

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. Asphalt also known as composite and wood are the traditional materials in this category. Then add 10 to the number to account for waste. This guide is a materials breakdown per square meter of roofing works.

Non friable materials such as floor tile roofing materials and their associated mastic binders are not good candidates for point count analysis they are better analyzed by gravimetric methods.
