  • Starter strip shingle and roof having same
    Patent number: 6874289
    Abstract: A starter strip shingle of a given vertical width is provided, having a severance line, from which a severance portion of the starter strip shingle may be removed, somewhat reducing the vertical width of the starter strip shingle, such that the installer of roofing material has an option to use full width starter strip shingles, or reduced width starter strip shingles, from the same package of uniform width starter strip shingles, to thereby enable a feathering of roofing shingles applied thereover, by means of a gentle transition zone, to avoid tears and punctures of the roofing shingles. Sealant areas on the starter strip shingles may be synchronized with the spacing and sizes of tabs of roofing shingles applied thereover, such that the sealant areas will always be under tabs of roofing shingles that are applied thereover, and not fall between the tabs into slots thereof.
