THE PROBLEM -Most metal shingle manufacturers are still incorporating outdated, deficient lock designs that can often direct significant water flow underneath the shingles.
Unanticipated volumes of water run onto thin tar paper or polypropylene underlays - punctured by thousands of nail holes and often just as many harder-to-seal screw holes from the shingle fasteners above. This is a recipe for eventual disaster, turning a premium, ‘life-time’ metal shingle into a continually degrading, 10-20 year and sometimes even less – roofing system.
Observation of both field and lab-tested engineering is essential to understanding and defeating the anti-gravity effects of capillary action inherent in many older, out-dated metal shingle designs using S-locks, tongue & groove locks, and even simple over-lapping ‘side lock’ joints.
