You wish to estimate the time for installation of new shingles on your house. To start, you will try to time driving one nail into a shingle. Assume that the shingle is already in place. You are kneeling on your roof facing the shingle. The hammer is on the roof on the right of the shingle. Nails are in your left pocket. Use the simplified MTM table (Table 7-5) to determine the time of driving one nail into the shingle. End with placing the hammer back on the roof.
