ShingleLock

ShingleLock™ is an engineered synthetic roofing underlayment for sloped roof applications. It has a patented ShingleLock™ mechanical and chemical slip resistant walking surface using an advanced polymer technology which helps prevent shingle bundles from sliding and delivers outstanding walkability. In addition, ShingleLock™ also features a state-of-the-art back-side coating technology which helps to hold the underlayment to the roof deck prior to installing fasteners. ShingleLock™ is designed for use under asphalt shingles, concrete tiles, all metal panels, synthetic shingles and primed cedar shakes. ShingleLock™ meets all the code requirements including ASTM D226, ASTM D4869 and AC 188 as required by ICC.
