Have your helper start at the bottom edge of your roof and roll out the roofing felt. Make sure the side edge is lined up properly with the edge of the roof, and that there is at a 1-inch overhang at the bottom edge of the roof.
Use the nail gun to secure the far side of the roofing felt with nails placed every 9 inches. Do the same along the bottom.
Place another row of roofing nails 18 inches apart, and 12 inches in from the seam where this roll of felt will meet the one next to it.
Follow the lines on the felt to make sure that the next roll vertically overlaps the first by one-third. Secure the top layer along the bottom with roofing nails spaced 9 inches apart.
Secure the rest of the roll the same way you did the first. Repeat until you reach the roof peak. Start back at the bottom, repeat until the roof is covered, and continue to the next side.
Cut around roof vents, heating vents and any other obstructions with your utility knife, as you go.
