Laminated shingles are more durable than traditional 3-tab shingle designs. Laminated shingles also give a more varied, contoured visual effect to a roof surface.
Organic shingles are generally paper (waste paper) saturated with asphalt to make it waterproof, then a top coating of adhesive asphalt is applied and ceramicgranules are then embedded.
Plain felt consists of a resilient, high-strength cellulose fiber mat that has been saturated with premium waterproofing bitumen resulting in a superior building material used specifically as a residential roofing underlayment.
