Symphony composite slate is a specially-engineered roofing shingle that mimics the look and feel of natural slate, but is lighter, more durable and a fraction of the price. All Symphony slate colors meet EnergyStar® requirements.
Multiple Sizes ... Available in either pre-blended 12" bundles or pre-blended multiple width bundles consisting of 6", 9" and 12" tiles, eliminating the need for on-site sorting. Thicker 1/2" profile for a richer, more beautiful appearance.
Impact Resistant ... The UL 2218 Class 4 Impact Test drops a 2-inch steel ball from 20 feet onto a shingle to see whether the shingle cracks. The steel ball hits the shingle at 90mph, which is a stronger force than most hail that hits a roof. A typical shingle often has ruptures or cracks on the surface immediately after impact, but Class 4-rated shingles show no evidence of tears, cracks or ruptures on front or back.
Durability ... 50-year limited transferable warranty; plus 7-year sureStart warranty that covers 100% of replacement and labor costs due to manufacturing defects.
Fire Resistant ... Underwriters Laboratories Class A Fire Resistance rating (with approved underlayment), the highest rating possible.
