Given data

*The given height of the roof above the ground is h = 12.2 m

*The value of the acceleration due to gravity is g = 9.8 m/s^2

The formula for the time taken by the ball to reach the ground is given as

$t=\sqrt[]{(2h)/(g)}$

Substitute the known values in the above expression as

$\begin{gathered} t=\sqrt[]{(2*12.2)/(9.8)} \\ =1.58\text{ s} \end{gathered}$

Hence, the time taken by the ball to reach the ground is t = 1.58 s
