Roof Area Estimator

Tips on measuring for roofing.

Roof area estimator.

To accurately calculate the area of your roof you must first determine its slope or pitch. The base width is the distance from one corner of your roof to the other at its base on the short side of your house. After measuring the area of the footprint you can estimate the actual roof area based on the angle of the roof. The following tools estimate the area of a roof as well as the amount of materials necessary to construct a roof of a given area.

Similarly if you using the area calculator tool to measure a roof with multiple levels you should do the individual section separately. The rise is the distance from the top of a stud wall to the peak of. The best part of a roofing calculator is that it offers a free insight into the total cost of the replacement roof project on a sq ft basis. As you begin to calculate various costs you will see that the cost is a result of the interplay of many different variables including roof area in terms of footage measurement of any roof extras like.

Our roof calculator uses base length and base width to find the estimated area. Roof pitches are described in terms of rise and run. This gives us a 3d roof area of 1 625 sq ft. Assuming this is a hip roof we multiply this by 1 1 which gives us roughly 18 squares or 1 800 square feet of the roof surface.

The run is the distance from the outside edge of a perimeter stud wall to the center of the house. For estimating purposes we also assume that there is a chimney a couple of dormers and two layers of old shingles that need to be torn off and removed before a new roof.
