Learn about Class 4, impact-resistant asphalt roofing shingles, how they earn their rating, and how they can help protect your roof from hail damage.
When hail strikes a non-impact resistant shingle, it knocks off outer layer granules, leaving the shingle vulnerable to UV damage and leaks. Greater damage will follow. The unrelenting protection of CertainTeed impact-resistant shingles is verified by Underwriter’s Laboratory through their Class 4 UL 2218 Impact Test.Steep-slope IR roofing materials are currently rated according to the standard test methods UL 2218 (Underwriters Laboratory 2012) or FM 4473 (FM Approvals 2005).Products that pass these tests often carry a visible stamp, usually on the packaging and/or on the material itself.
scope: This test method provides impact resistance data for the evaluation of prepared steep slope roof covering materials. For purposes of this Standard, prepared roof covering materials are considered to be small units, sheets or panels designed for installation with multiple layers of such materials installed in overlapping rows on slopes of 2:12 (16.67%) and .The tests simply provide a basis to compare each shingle’s ability to deal with impact forces as manufactured. Testing for UL 2218. In the Underwriters’ Laboratories 2218 test, researchers drop steel balls onto the shingle surface to replicate the force of hail. This test is intended to assess the mettle of the most vulnerable parts of the . The industry guideline UL 2218 tests a metal panel’s resistance to puncturing or failing when it comes into contact with items, such as hail or other small debris. The testing method “.provides impact resistance data for the evaluation of prepared roof covering materials.The test evaluates the effect of impact from a steel ball at .
UL 2218 Class 4 Impact-Resistant. Timberline ® AS II Shingles are made with our proprietary SBS-modified asphalt formulation and pass UL’s toughest impact-resistance test — UL 2218 Class 44. That means they can really take a punch from Mother Nature.
Certifications such as UL 2218 and FM Approvals 4473 validate a roofing material’s ability to withstand impact through rigorous testing procedures. The ball-drop test, simulating hailstone impact, and the wind-driven debris test replicating storm-related airborne object impact are crucial evaluation methods. Impact resistan ce for roof coverings are rated by Underwriter Laboratories (UL) between Class 1 and 4, with Class 4 being the most durable. How Impact Resistance for Roofing Shingles Is Measured To measure the .

The UL 2218 Impact Test involves dropping steel balls of varying sizes and weights from specific heights onto a shingle. The resulting damage is carefully assessed to determine the shingle's resilience. The rating scale ranges from Class 1 to 4, with Class 4 having the highest level of impact resistance.Our AccuDrop® steel ball tester helps perform UL 2218 tests faster, using fewer test specimens and with a more economical test process. Rigorous quality control governs our testing procedures. IAS accredited Steel Ball Dropping test: UL 2218, January 25, 2010—Impact Resistance of Prepared Roof Covering Materials UL testing Three new shingle samples were subjected to additional steel sphere impact per UL 2218. Sample A is a laminated modified shingle; sample B is a modified three-tab shingle; and sample J is an asphalt three-tab shingle. Samples A, B and J are marketed with a UL 2218 Class 4 rating and in compliance with ASTM D3462. Another test method, UL 2218, “Impact Resistance of Prepared Roof Covering Materials,” classifies asphalt shingles on their relative resistances to steel-ball-simulated hail impacts. UL 2218’s Class I, Class II, Class III and Class IV represent tested resistances to impact energies of 3.53 ft-lbs., 7.35 ft-lbs., 13.56 ft-lbs. and 23.71 ft .
