What this means for your roof
TAMKO recommends keeping laminated-shingle bundles flat in their packages rather than bending them over ridges, hips or valleys. Concentrating too many bundles in one area can overload the structure. The bulletin illustrates loading practices intended to reduce distortion before installation.
A useful question for your contractor
Ask how the delivery and roofing crews will distribute bundles and avoid bending them over roof transitions.
Ask for the answer to be tied to the actual roof condition and the exact product being installed. Keep the agreed repair or installation detail with your estimate and project photos.
