Quick Tip: Shingling a Roof
If you are going to shingle a roof the do-it-yourself way, employ the technique described here for a high-performing, long-lasting installation.
Here is a tip you can use to shingle your own roof. Make a starter course at the edge of the eave, laying the shingles upside down. Trim one-third off your first shingle, so the joints will be staggered, then lay your first course over that, with tabs down. Form a pyramid of overlapping shingles, trimming each by six inches so that all rows will have overlapping joints. Then continue to lay rows from bottom to top, using whole shingles.
