Two Roofs in One Week

Monday gives you two roofs. The Hendersons' two-story house needs a tear-off and re-shingle — composition shingles, a 6:12 main roof, eaves about nineteen feet above the yard. And the strip-mall unit you are GC-ing wants its built-up roof recovered — essentially flat, call it 1:12, the roof edge twenty-two feet above the parking lot. Your roofing foreman has run crews for fifteen years and wants one plan for both jobs: 'Roofs are roofs.'
