Installation:
Beginning at a bottom corner of the roof, lay felt courses horizontally. Carefully cut off the binding - but don´t cut into the roll - and unravel 2 or 3 feet of the roll. Position the roll of felt so that it can be rolled across the bottom of the roof, even with the eaves. Kneel and hold the roll in both hands. Maneuver the felt into position so that it covers the deck right up to the edge of the rake and eaves but not over the sides of the building.
When you are satisfied that the roll is positioned properly, drive about five nails into the top right-hand corner of the felt. Roll out the felt no more than midway (perhaps 25 feet or so) across the average-size roof. If there is any wind at all, roll out the felt only about 10 feet.
