This tip is for the homebuilder who has either run out of time, money or both and needs to get a roof covered before the next rain. I’ve tried it and it works on roofs with a minimum 4/12 pitch in any weather condition short of a gale.
After whatever sheathing you are using is in place, cover it with 30-lb. felt using any appropriate lap, and then staple string 1/2 in. above the lap line. Use kite string, mason’s line, fishing line, or some other small-diameter string with at least 15-lb. test. The staples should be at least 1/2 in. long (5/8 in. is even better) and place them 10 in. on center for effective holding. Be careful to staple every exposed edge, vertical or horizontal, or a good wind will pick off the felt. The string can be left in place when the finished roof is installed.
