Yes, you can absolutely use roofing felt seconds for almost any project. At JS Roofing Supplies, our seconds are brand new, unused rolls that have been downgraded by manufacturers like IKO for minor cosmetic reasons. This might include a scuff on the wrapper, a slight colour variation in the mineral, or a marking on the edge of the roll.
Performance vs Aesthetics
The structural integrity and waterproofing performance of a “second” roll are identical to a “first” quality roll. If you are looking for the best value for money and don’t mind a minor cosmetic imperfection that is often invisible once installed, roofing felt seconds are the perfect choice for trade and DIY projects.
