I have a client with a 2/12 pitch roof. The previous homeowner had install arch comp roofing shingles in a 350sq ft area. This area has failed and needs roofing and structural repairs. She doesn't want a roof with differing materials and doesn't like the look of Torch Down. Is there a way to laminate shingles over Torch Down? Is there a value engineered and aesthietic solution to her problem? Thanks!
