How to figure roofing squares.

As such while it can be cumbersome measuring the area and pitch of each part of the roof and multiplying by the corresponding correction factor will result in the most accurate estimate of necessary.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.

If the house has an irregular shape measure each part separately figure the separate areas and add them together. Remember that unless the roof is flat the square footage of the building is different than the square footage of the roof.

While it is possible to estimate the amount of necessary materials using only the total roof area measurement as can be seen from the table depending how large the pitch of the roof the actual area of the roof can differ by up to 2 236 from the measured total area at a pitch of 24 12. Although roofing projects are estimated and sold by the square roofing material is often not sold in 1 square increments. A square refers to 100 square feet of roof or a 10 foot by 10 foot area.
