Площадь крыши is a free Android application developed by ProstoBuild. This business and productivity app is designed to help users calculate the area of their roof. The app includes four different types of roof area calculations: gable, hip, shed, and mono-pitched. Each calculation requires only the minimum number of unknown values to obtain an accurate area measurement. The app is ideal for homeowners, builders, roofers, and architects.

To calculate the area of a gable roof, the user needs to input the dimensions of their home, the height to the ridge, and the roof overhangs on both sides. The same goes for a hip roof. The app calculates the area of the roof using these inputs. For a shed roof, the user needs to input the dimensions of the home, the height to the top, and the overhangs. For a mono-pitched roof, the user inputs the dimensions of the home, the height difference between the two walls, and the overhangs.

Overall, Площадь крыши is a handy app for anyone looking to calculate the area of their roof with ease and accuracy.
