TAMKO technical bulletin: Proper Storage of Asphalt Shingles.
What this means for your roof
Cool, dry, ventilated storage and a level support help prevent sticking, distortion and staining. TAMKO recommends stock rotation and limits pallet stacking, with a separate warning for Heritage Vintage packaging. Long outdoor storage can create avoidable handling problems even before shingles reach the roof.
A useful question for your contractor
Ask how delivered bundles will be protected and how damaged material will be removed from the installation supply.
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.
